A scooter designed for a 7A battery cannot accommodate a 7L battery and vice versa.What is the difference to the YTX9-BS?Both batteries have exactly the same base area (150 x 87 mm). The difference is the height.YTX7A-BS: 93 mm high.YTX9-BS: 105 mm high. The YTX9 is 1.2 cm higher and has more performance (8 Ah). If there is clearance in your battery compartment at the top, you could theoretically install the more powerful YTX9. However, in most scooters the space is so tight (lid will not close) that only the flat YTX7A will fit.Do I need to charge the battery?Yes. As this is a relatively small battery, the charge level after filling (approx. 75-80%) is often not adequate for maximum service life. Charge the battery fully before installation using a suitable charger (max. 0.6 ampere).Where is the positive terminal?With the YTX7A-BS, the positive terminal is on the left side (when viewed from the front at the terminals). This is important, as the cables in the scooter are usually very short and would not reach the other side.

The Yuasa YTX5L-BS (or YTX5L as a factory-filled version) is a widely used AGM battery for scooters in the 80-125cc class as well as for sports enduros. It shares the footprint with the smaller YTX4L but is built higher to hold more lead plates. With a capacity of 4 Ah (10h) or 4.2 Ah (20h) and a cold cranking current of 80 A (EN), it provides around 30% more energy than the smaller 3Ah model, making it the standard choice for many 4-stroke scooters and competition enduros.Highlights at a glanceThe standard for 125cc & enduros: Very frequently used in 4-stroke scooters (e.g. Honda Lead, Peugeot Speedfight 100) and almost all KTM EXC-F 4-stroke enduros.Compact power format: Uses the small footprint (114 x 71 mm) but offers considerably more starting reserves than the flatter YTX4L because of its height of 106 mm.AGM technology: The acid is bound in the glass fleece, making the battery leak-proof and extremely vibration-resistant – essential for enduros in tough off-road use.Maintenance-free: Thanks to VRLA (valve-regulated) technology, the system is hermetically sealed after first filling; topping up with water is not possible and not required.Solid starting power: With 80 A cold cranking current it reliably starts single-cylinder engines up to approx. 250cc (4-stroke) or 125cc (2-stroke).Position independence: Can (after correct activation) also be installed at an angle, which is often required by the design of modern sports motorcycles.The favourite for KTM & Honda scootersThe YTX5L-BS is the typical battery for the KTM EXC series (e.g. 250/350/450/500 EXC-F), where it must work reliably despite hard jolts and jumps. It is also a bestseller in the scooter sector, among others for the Vespa ET4 / LX 50-125, Honda Shadow 50/90 or Suzuki Address. It is the perfect balance between low weight and sufficient power. Characteristics ModelYuasa YTX5L-BS (Maintenance Free) Application4-stroke scooter (50-125cc), KTM EXC-F, Honda 125cc TechnologyAGM (VRLA) - Dry pre-charged (incl. acid pack) Voltage12 V Capacity4 Ah (10 hrs) / 4.2 Ah (20 hrs) Cold cranking current (CCA)80 A (EN) Dimensions (L x W x H in mm)114 x 71 x 106 (Higher than YTX4L) Pole arrangement0 (positive terminal right) TerminalType 5 (Front/Top mounting) Base barN (No base bar) Special featuresTilt-proof up to 45° (after filling), standard for 4-stroke scooters Weight (kg)approx. 2.0 (filled)  FAQs on Yuasa YTX5L-BSWhat is the difference to the YTX4L-BS?The footprint is identical (114 x 71 mm), but the height is the decisive factor.YTX4L-BS: 86 mm high (3 Ah).YTX5L-BS (your battery): 106 mm high (4 Ah). The YTX5L is 2 cm higher. It has more power, but only fits if the battery compartment allows this extra height (seat must still close).Can I use this battery as a replacement for YB4L-B?Yes and no.YB4L-B (acid): 93 mm high.YTX5L-BS (AGM): 106 mm high. The YTX5L is 1.3 cm higher than the classic YB4L-B. If your classic vehicle (e.g. Simson) has room above, the YTX5L is a great technical upgrade (maintenance-free, more starting current). If space is tight, it will not fit.What does YTZ6V or YTZ7S mean?In newer sports enduros (KTM, Honda), batteries labelled YTZ6V or YTZ7S are often installed at the factory. These have the same size as the YTX5L-BS (114x71x106 mm), but an even higher performance and capacity (High Performance AGM). The YTX5L-BS is the affordable standard alternative, and the YTZ models are the more expensive premium upgrades.Do I need to charge the battery?Yes. As the volume is relatively small, the battery is sensitive to undercharging. After filling (BS version), it should definitely be fully charged with a motorcycle charger (max. 0.4 - 0.6 amp charging current) before installation. This guarantees full starting power for the single-cylinder.

The standard version is cheaper and is perfectly adequate for normal use and moderate climates. If you ride in extreme sub-zero temperatures or have a high-compression tuning engine, you should opt for the HL version.What is the difference from the YTX20-BS (without L)?The difference is the polarity.YTX20-BS: Positive terminal is left.YTX20L-BS (your battery): Positive terminal is right. Since battery cables on motorbikes are usually very short and rigid, the wrong battery often cannot be connected. Check the position of the terminals on your old battery before buying.Does this battery fit in a jet ski?Yes, the YTX20L-BS is one of the most frequently used batteries for jet skis (PWC) from Sea-Doo, Yamaha, Kawasaki and Polaris. Thanks to AGM technology, it is leak-proof and can withstand “bouncing” on the waves. Good maintenance is particularly important in winter (removal and charging), as jet skis often have long periods of inactivity.

The Yuasa YTX16-BS (often also referred to as YTX16 when factory-filled) is a high-performance AGM battery specially developed for motorcycles with increased energy requirements. It shares its footprint with the widely used 12 and 14 models, but makes maximum use of the available height in the battery box to accommodate more lead plates and acid volume. With a capacity of 14 Ah (10h) or 14.7 Ah (20h) and a cold start current of 230 A (EN), it offers significantly more reserves for large-displacement cruisers and touring machines.Highlights at a glanceMaximum capacity in a small area: Uses the standard footprint (150 x 87 mm), but at 161 mm is significantly higher than a YTX14. This results in almost 15 Ah capacity for long service life and plenty of accessories.AGM technology: The acid is bound in glass fleece (Absorbent Glass Mat), making the battery leak-proof, vibration-resistant and cycle-resistant – ideal for heavy V2 cruisers.Strong starting power: With 230 A cold start current, it reliably turns over even large engines (like 1500 or 1600 V-Twins).Maintenance-free: Thanks to VRLA technology (valve regulated), the system is hermetically sealed after initial filling; topping up water is neither possible nor necessary.The "high-rise" format: Specially designed for battery boxes that are deep but allow little width (e.g. Kawasaki VN 1500/1600, Suzuki Marauder 1600).Long service life: The robust construction and larger amount of acid provide better thermal stability and durability compared to smaller batteries.The powerhouse for heavy cruisersThe YTX16-BS is the standard battery for many "big bikes", especially from the chopper and cruiser segment. It is indispensable for models such as the Kawasaki VN 1500 / 1600 Mean Streak, the Suzuki VZ 1600 Marauder or even some Triumph Tiger 800 models (depending on year/equipment). It provides enough buffer to keep the voltage stable even with a lot of chrome accessories (auxiliary headlights, sound systems). Features ModelYuasa YTX16-BS (High Performance MF) ApplicationMotorcycle & ATV (Cruiser & Adventure - e.g. Triumph Tiger 800) TechnologyAGM (VRLA) - Dry pre-charged (incl. acid pack) Voltage12 V Capacity14 Ah (10 h) / 14.7 Ah (20 h) Cold start current (CCA)230 A (EN) Dimensions (L x W x H in mm)150 x 87 x 161 (higher than YTX14) Pole arrangement1 (positive pole left) Terminal typeType 4 (Front/Top Mounting) Base stripN (No base strip) Special featuresTilt-resistant up to 45° (after filling), high reserve capacity Weight (kg)approx. 5.3 (filled)  FAQs about the Yuasa YTX16-BSWhat is the difference to the YTX14-BS?Both batteries have the same length (150 mm) and width (87 mm). The difference is the height.YTX14-BS: 145 mm high (12 Ah).YTX16-BS: 161 mm high (14 Ah). The YTX16 is 1.6 cm higher. It only fits in vehicles that have this extra space at the top. Theoretically it can be used as an upgrade for the YTX14 if the seat can then still close.What is the difference to the YTX20-BS?The YTX20-BS is a completely different size class.YTX16-BS: 150 mm long.YTX20-BS: 175 mm long. The 20 battery is much longer and will not fit in the 16 holder.Is there a YTX16-BS-1?Yes, the suffix "-1" at Yuasa often indicates a different pole arrangement or terminal type. With the YTX16-BS-1 the pole arrangement is usually identical (positive left), but to be sure always check the pictures of the terminals and the position of positive/negative on your old battery before ordering.Do I need to be aware of anything with the BS version?Yes, with the "Bottle Supplied" version you have to fill in the acid yourself. Important: After filling, leave the battery open for approx. 1 hour ("outgassing") before pressing on the sealing strip. Then charge it fully with a motorcycle charger. Once sealed, it must never be opened again.

The Yuasa YTX14H-WC is the performance-enhanced "High Performance" version of the widely used YTX14 standard battery. The "H" in the type designation stands for a significantly higher starting power, which is achieved by an optimised grid structure and additional plates inside. With 240 A cold start current (instead of the usual 200 A), it offers significant reserves for engines that are difficult to start, large V2 units or use at low temperatures. The suffix "WC" (Wet Charged) usually identifies it as a factory-filled and sealed variant that is ready for immediate use.Highlights at a glanceHigh performance series: Delivers up to 20% more cold starting current (240 A) than the standard YTX14, which ensures powerful cranking of the starter especially with large displacements.Wet Charged (WC): The battery is usually supplied factory filled, charged, and hermetically sealed, eliminating the need to handle acid packs and enabling immediate installation.AGM technology: Due to the electrolyte bound in the glass mat, the battery is leak-proof, extremely vibration-resistant, and maintenance-free (no need to top up water).Identical dimensions: Despite higher performance, it has exactly the same case (150 x 87 x 145 mm) as the standard battery and fits into the battery box without modifications.Cold start specialist: Ideal for vehicles also used in winter (e.g. snowmobiles, ATVs) or motorcycles with high current demands at start (ABS systems).Long service life: The compacted plate structure and the sulphation inhibitor ensure high cycle resistance and robustness against vibrations.The power pack for BMW & V-TwinsThe YTX14H-WC is the ideal upgrade for motorcycles that are equipped with a 12Ah/14Ah battery at the factory but struggle to start. It is particularly popular with riders of the BMW R1200 GS (LC), large Honda V-Twins (VTX 1300, Shadow 1100), Aprilia Dorsoduro/Shiver or various Piaggio maxi scooters.

The Yuasa YT14B-BS (often also referred to as YT14B-4) is a special AGM high-performance battery with the characteristic, very slim design. It is the "big brother" of the YT12B-BS and was specially developed for heavy motorbikes that have little space in width but nevertheless require a high capacity. With approx. 12 Ah (according to the 10h standard) or 12.6 Ah (according to the 20h standard) and a cold start current of 210 A, it is the standard power unit for large Yamaha tourers and cruisers.Highlights at a glanceExtra slim design: At only 70 mm wide, it is extremely slim (just like the YT12B, but taller) to fit into special battery boxes where standard batteries would be too thick.AGM technology: The acid is bound in the glass fleece, which makes the battery leak-proof, extremely vibration-resistant and maintenance-free – ideal for heavy touring machines.High capacity: Offers 12.6 Ah, providing sufficient reserves for additional electrical consumers such as heated grips, navigation devices or electric windscreens on touring bikes.Maintenance-free: Thanks to VRLA technology (valve regulated), there is no need to top up with water; the system is hermetically sealed after initial filling.Reliable start: Delivers approximately 210 A cold start current to reliably start even large-displacement four-cylinder or V2 engines in cold conditions.Yamaha specialist: Was developed specifically as original equipment for models such as the Yamaha FJR 1300 or MT-01.The specialist for Yamaha FJR & MT-01The YT14B-BS is almost inextricably linked to the Yamaha brand. It is the original battery for the Yamaha FJR 1300 (all model years), the Yamaha MT-01 (1700cc), the Yamaha XJR 1300 (from 2007) or the Yamaha BT 1100 Bulldog. These motorbikes have a very narrow battery compartment into which the regular "YTX14-BS" (which is much thicker) does not fit mechanically. Features ModelYuasa YT14B-BS (High Performance MF) ApplicationMotorbike (Yamaha specialist - FJR1300, MT-01, XJR1300) TechnologyAGM (VRLA) - Dry pre-charged (incl. acid pack) Voltage12 V Capacity12 Ah (10 hrs) Cold start current (CCA)210 A (EN) Dimensions (L x W x H in mm)152 x 70 x 145 (extremely slim & tall) Pole arrangement1 (positive pole left) Connection terminalType 11 (front/top mounting) Base barN (No base bar) Special featuresTilt-proof up to 45° (after filling), high starting power, maintenance-free Weight (kg)approx. 4.6 (filled)  FAQs about the Yuasa YT14B-BSWhat is the difference to the YTX14-BS?The crucial difference is the width.YTX14-BS (standard): 150 x 87 x 145 mm.YT14B-BS (your battery): 150 x 70 x 145 mm. The YTX14-BS is almost 2 cm thicker. You can't fit the YTX14-BS in a Yamaha FJR 1300. So be sure to look for the "B" in the name (YT14B).What is the difference to the YT12B-BS?Both are equally slim (70 mm) and equally long. The difference is in the height and performance.YT12B-BS: 130 mm high (approx. 10 Ah).YT14B-BS: 145 mm high (approx. 12.6 Ah). So the YT14B is 1.5 cm taller. It offers more power, but only fits if there is still room upwards (often the seat or frame strut). Upgrading from 12B to 14B is usually not mechanically possible.Do I have to charge the battery before installation?For the "BS" version (with acid pack), fill in the acid and allow the battery to stand ("gas out") for approx. 30–60 minutes. It then has about 70–80% charge. To achieve the maximum service life, it is strongly recommended to fully charge it with a motorbike charger before installation. With the factory-filled version (YT14B-4), you should check the voltage and recharge if necessary if it has been on the shelf for a long time.

The Yuasa YT9B-BS (often also referred to as YT9B-4) is a specialised AGM battery in a flat design. It fills exactly the gap between the very small YT7B and the larger YT12B. With a capacity of approx. 8 Ah (10h) or 8.4 Ah (20h) and a cold cranking current of approx. 115 A (EN), it is the standard power source for many mid-range motorbikes and maxi scooters, especially from Yamaha. It combines compact dimensions with high vibration resistance for single-cylinder engines.Highlights at a glanceFlat housing: At only 70 mm width it is significantly narrower than standard batteries (such as the YTX9-BS), making it ideal for slim tail frames or tight fairings.AGM technology: The acid is bound in the glass mat, making the battery leak-proof (up to 45° tilt) and extremely vibration-proof – perfect for the "vibrating plate" Yamaha XT660.Maintenance-free: Thanks to VRLA technology (valve-regulated), the system is hermetically sealed after the first fill; topping up with water is not possible and not required.Starting power for singles: Reliably delivers the necessary current (~115 A) to turn large single cylinders (660cc) past top dead centre.Long service life: The sulphation inhibitor and robust construction ensure good durability, even in seasonal use (with proper care).Yamaha standard: Specially developed as original equipment for the popular 660 models and the T-Max scooter.The standard for Yamaha XT660 & T-MaxThe YT9B-BS is the indispensable battery for owners of a Yamaha XT660 (R, X or Z Tenere) as well as the Yamaha MT-03 (the old 660 version). These single-cylinder motorcycles need a vibration-resistant battery that fits the narrow compartment. Early models of the maxi scooter Yamaha T-Max 500 also use this special type. Features ModelYuasa YT9B-BS (High Performance MF) ApplicationMotorcycle & Scooter (Yamaha specialist - R6, XT660, T-Max) TechnologyAGM (VRLA) - Dry pre-charged (incl. acid pack) Voltage12 V Capacity8 Ah (10 hrs) / 8.4 Ah (20 hrs) Cold cranking current (CCA)115 A (EN) Dimensions (L x W x H in mm)150 x 70 x 105 (Narrow & Compact) Pole arrangement1 (Positive pole left) Connection terminalType 11 (Front/Top mounting) Bottom railN (No bottom rail) Special featuresTilt-proof up to 45° (after filling), vibration-proof, maintenance-free Weight (kg)approx. 3.1 (filled)  FAQs about the Yuasa YT9B-BSWhat is the difference to the YTX9-BS?This is the most common confusion.

The difference is in the Width.YTX9-BS: 87 mm wide (the "thick" standard, e.g. Kawasaki Z750, Honda CBR).YT9B-BS: 70 mm wide (the "slim" special version, e.g. Yamaha XT660). If you ride a Yamaha XT660, the YTX9-BS will not fit into the compartment (too thick). Pay close attention to the "B" in the middle (YT9B).What does YT9B-4 mean?This is technically the same battery as the YT9B-BS.YT9B-BS: "Bottle Supplied" – The battery is supplied dry pre-charged with a separate acid pack (shipping standard).YT9B-4: Often the code for the already factory-filled and sealed version (Factory Activated). Dimensions and performance values are identical.Can I install the battery lying down?Yes, to some extent. As it is an AGM battery, the acid is bound. Many manufacturers (like Yamaha in the T-Max or Ducati in other models) install this battery type horizontally. It is important that after filling (in the BS version) the battery rests for about 1 hour and is then sealed 100% correctly with the sealing strip. It is then leak-proof.Is the starting power sufficient for my 660 in winter?The YT9B-BS is sufficiently dimensioned for the 660 engine, but does not have huge reserves. In very cold temperatures and with viscous oil, the starter has difficulty with single-cylinder engines. Make sure to recharge the battery regularly in winter (maintenance charger), as even a small voltage drop can mean the starter won't turn the piston over compression.

The Yuasa YT12A-BS (often referred to as "WC" for "Wet Charged" when supplied already filled) is a compact high-performance motorbike battery in AGM technology. It has been specially developed to provide high starting power in a very small case. It is the standard for many modern Suzuki sports bikes which have little space under the seat but need to start a powerful engine. With a capacity of approx. 10–10.5 Ah and 175 A cold starting current, it is extremely power-dense.Highlights at a glanceAGM technology: The acid is bound in the glass fibre mat (Absorbent Glass Mat), which makes the battery leak-proof (up to 45° tilt) and highly resistant to vibration.High power density: Delivers the starting power of a classic YTX12-BS, but is much smaller and lighter to save weight on the motorbike.Maintenance-free: Thanks to VRLA technology (valve regulated), there is no need to refill with water throughout its lifetime (never open!).Special format: Dimensions of 150 x 87 x 105 mm – a special size which is hardly mechanically replaceable by other types.Long service life: Sulfation inhibitor ensures longer durability, even if the motorbike stands unused for longer (with proper care).WC vs. BS: "WC" usually means factory filled/activated, "BS" is supplied with an acid pack (Bottle Supplied) for initial filling; they are technically identical.The compact powerhouse for Suzuki GSX-R and SVThis battery is well-known as the original equipment for the Suzuki GSX-R 750/1000, the Suzuki SV 650 (K3 models or newer) or the Suzuki Bandit 1250. The engineers here chose a battery that is extremely flat (only 10.5 cm high) and narrow, to optimise the motorbike's centre of gravity. It should never be confused with the normal YTX12-BS, which is much taller and would not fit. Features ModelYuasa YT12A-BS / YT12A-WC ApplicationMotorbike & scooter (High Performance MF – e.g. Suzuki Hayabusa) TechnologyAGM (VRLA) – Maintenance-free (sealed after filling) Voltage12 V Capacity10.5 Ah (20 hr) / 10 Ah (10 hr) Cold start current (CCA)175 A (EN) Dimensions (L x W x H in mm)150 x 87 x 105 Pole orientation1 (Positive pole left) Connection terminalType 5 (Front/top mounting) Base plateN (No base plate) Special featuresTilt-proof up to 45°, high starting power, compact Weight (kg)approx. 3.5 (filled)  FAQs for Yuasa YT12A-BS / WCWhat does the "WC" in my designation mean?"WC" often stands for "Wet Charged" (charged wet) or an internal production code for batteries that have already been factory filled and sealed and supplied to the vehicle manufacturer.

You definitely need the YT12A-BS, as other batteries won't fit in the battery compartment or will prevent the seat from closing.How do I charge this motorbike battery correctly?Use a smart automatic charger for motorbikes (e.g. Optimate or CTEK XS 0.8) suitable for AGM batteries. Never use a large car charger, as too high a current can damage ("inflate") the small battery. The charging current should not regularly exceed about 1 amp.Do I need to top up with water?No, never. After the initial filling (for the BS version), the sealing strip is pressed on and the battery is hermetically sealed. If you open the strip, the battery is destroyed because the chemical balance is disrupted.

The Yuasa YT12B-BS (often also referred to as YT12B-4) is a special AGM high-performance battery with a very slim design. It was primarily developed to fit into the narrow battery boxes of Ducati motorbikes and some Yamaha models, without sacrificing starting power. With a capacity of approx. 10 Ah (often specified as 10.5 Ah) and a strong cold start current of 210 A (EN), it reliably starts large-displacement two-cylinder engines.Highlights at a glanceExtra slim design: At just 69 mm wide (instead of the usual 87 mm), it is extremely slim and fits into special holders in which no other 12-series battery will fit.AGM technology: The acid is bound in the glass fleece, making the battery leak-proof, vibration-resistant and absolutely maintenance-free.High starting power: Despite its compact dimensions, it delivers approx. 210 A cold start current, ideal for the high compression resistance of Ducati L-Twins or Yamaha cruiser engines.Maintenance-free: Thanks to VRLA technology (valve-regulated), water never needs to be refilled after initial filling.Long service life: The robust plate construction protects against vibrations (important for V2 engines) and reduces self-discharge in winter.OE quality: Yuasa is the OEM supplier for Ducati and Yamaha for this battery type.The classic for Ducati & YamahaThe YT12B-BS is the standard battery for almost all modern Ducati models (Monster, Hypermotard, Multistrada, Panigale – older model years) as well as for the Yamaha YZF-R1 (RN12/RN19) or the Yamaha Drag Star XVS 650. Its special feature is the "disc shape": it is as long and high as a normal battery, but much thinner. Anyone who tries to install a cheaper standard battery here will fail, as the battery box is too narrow. Features ModelYuasa YT12B-BS (High Performance MF) ApplicationMotorbike (Ducati & Yamaha specialist - slim design) TechnologyAGM (VRLA) - Dry pre-charged (incl. acid pack) Voltage12 V Capacity10 Ah (10 h) Cold start current (CCA)210 A (EN) Dimensions (L x W x H in mm)150 x 69 x 130 (Very slim) Pole arrangement1 (Positive pole left) Connection terminalType 11 (Front/Top Mounting) Base railN (No base rail) Special featuresTilt-proof up to 45° (after filling), high starting power, maintenance-free Weight (kg)approx. 4.1 (filled)  FAQs about the Yuasa YT12B-BSWhat is the difference to the YT12A-BS?The dimensions are completely different, although the performance is similar.YT12B-BS (your battery): 69 mm wide, 130 mm high (Narrow & Tall).YT12A-BS: 87 mm wide, 105 mm high (Wide & Flat).

For the 6V block this means 6.825 Volt total voltage.Features ModelYuasa SWL+2800-6 (High Rate Monoblock) Voltage**6 V** (3 large-volume cells) Capacity**184 Ah** (High Capacity) / Optimised for high current Technology**AGM VRLA** (Sealed, recombination) Design Life**10 - 12 years** (EUROBAT: Long Life) Dimensions (L x W x H in mm)approx. 297 x 168 x 232 (typical 6V industrial size) Connection**M8 internal thread** (For heavy-duty cable connectors / copper bars) Weight (kg)approx. 33.0 - 35.0 kg (Very heavy!) Special featureIdeal for systems requiring high Ah values with a compact footprint  FAQs about the Yuasa SWL+2800-6Why use 6V blocks instead of 12V?With very large batteries (over 100 Ah), 12V blocks often become unmanageable and more thermally susceptible. 6V blocks provide the "sweet spot": they are more robust than 12V blocks, but easier to install than many individual 2V cells. They provide higher operational safety in large strings.What does the "2800" mean?The number refers to the performance in watts that the block can deliver during a short-term discharge (typically 10 minutes). For UPS engineers, this value is often more important than pure capacity (184 Ah) because it defines the maximum load the UPS can support.Is the thread M6 or M8?In this performance class (over 150 Ah), Yuasa almost always uses M8 internal thread to safely transfer the high currents and minimise connector resistance. M6 would be too weak here.

A loose connection will immediately cause dangerous heat to develop at this power level.FR compliance: Never replace a defective block in an existing FR string with a standard version (black/HB), as this cancels out the fire protection class of the entire system.Cooling: Ensure that there is approximately 10mm space between the blocks for air circulation, to prevent heat build-up inside the block. Features  ModelYuasa SWL+4300FR (Flame Retardant) Housing Specification**Flame-retardant** to UL94 V-0 (self-extinguishing) Voltage12 V Capacity**140.0 Ah** (C10) / **150.0 Ah** (C20) - The maximum Performance (10 min)approx. **4300 Watts** per block (Extreme energy density) Technology**AGM VRLA** (Sealed, maintenance-free, FR case) Design Life**10 - 12 years** (EUROBAT: Long Life) Dimensions (L x W x H in mm)approx. 341 x 173 x 281 (Identical to SWL4000) Connection**M8 female thread** (Female) Weight (kg)approx. **52.5 kg** (Extremely heavy!)  FAQs about the Yuasa SWL+4300FRWhat is the difference compared to the standard SWL+4300?The difference is solely in the case material.SWL+4300: Standard ABS (UL94 HB).SWL+4300FR: Flame-retardant (UL94 V-0). Technically, both deliver the same enormous performance. However, the FR version is required in most commercial tenders (especially data centres).Will this battery fit in my old cabinet for 120Ah batteries?Be careful with the weight. The dimensions (footprint) are often similar to 120Ah blocks (e.g. SWL3800). But the SWL+4300FR is significantly heavier (~50kg vs. ~40kg). Be sure to check if your cabinet shelves can support this additional weight before you upgrade.Why M8 connections?With a discharge capacity of 4300 watts per block, currents are so high that an M6 thread would become too hot. M8 offers more contact area and safety for the transmission of these enormous amounts of energy.

The Yuasa SWL+2900-12FT is a highly specialised VRLA battery in the Front Terminal design (FT). With a nominal capacity of 96.8 Ah (often classified as 100Ah class) and the proven SWL+ high current technology, this battery has been specifically developed for telecommunications applications and 19-inch UPS cabinets designed.The "FT" in the name stands for the front-mounted terminals. This allows extremely simple installation and maintenance in tight rack systems, as no dangerous work is required above the batteries. Combined with a life expectancy of 12+ years (Very Long Life) this is the ideal solution for space-critical data centres and network nodes.Highlights at a glanceFront Terminal design (FT): The terminals are located on the front of the slim block. This enables quick installation and voltage measurement directly from the front, without having to pull the batteries out of the rack.Optimised for 19" & 23" cabinets: The design is long and narrow. As a result, for example, four of these blocks fit perfectly side by side in a standard level of a 19-inch server cabinet or ETSI rack.High energy density (96.8 Ah): Despite its compact footprint, the block offers almost 100 Ah capacity. It is ideal for long bridging times in telecommunications or short high-current phases in the UPS.Central degassing possible: The FT series usually has connections for hoses for central degassing. This allows any escaping gases to be specifically directed out of the closed cabinet.Eurobat "Very Long Life": Classified for 12+ years. The SWL+ technology uses improved grid alloys to minimise corrosion and maximise service life even with fluctuating temperatures (typical for outdoor telecom cabinets).Maintenance-free: VRLA-AGM technology (Absorbent Glass Mat). No water topping up needed, leak-proof and vibration-resistant.Areas of applicationThe SWL+2900-12FT dominates wherever space is money and maintenance needs to be quick:Telecommunications: Base stations (BTS), outdoor enclosures, switching centres.UPS systems (rackmount): In server rooms, where batteries are installed directly in the IT rack.Renewable energies: Buffer storage in compact control cabinets.Railway technology: Signal systems (thanks to vibration resistance and compactness).Assembly & Maintenance (Front Terminal Advantages)Simple voltage measurement: As the terminals are at the front, a technician can check the block voltages (SOH check) in seconds by simply opening the rack door.Safe installation: There is no need to reach over the terminals with tools (minimising risk of short circuits).Torque: The M8 front terminals should be tightened with the prescribed torque (usually approx. 6 Nm) as specified.Monobloc connectors: Rigid copper connectors or short flexible bridges are often provided/required to interconnect the blocks side by side.Features ModelYuasa SWL+2900-12FT (Front Terminal) Design**Front Terminal** (connections at the front) Voltage12 V Capacity (Nominal)**96.8 Ah** (C10) / approx. **100 - 103 Ah** (C20) Performance (10 min)High rate performance (optimised for short bridging times) Design Life**10 - 12 years** (EUROBAT: Long Life) Dimensions (L x W x H in mm)approx. 395 x 108 x 287 (long and narrow for racks) Connection**M8 internal thread** (accessible from the front) Weight (kg)approx. 33.0 - 34.0 kg Application19" / 23" cabinets, telecommunications (BTS), UPS  FAQs about the Yuasa SWL+2900-12FTWhat is the difference to a normal SWL2900?The difference lies purely in the design.Standard (Top Terminal): Terminals are located on top of the lid. The block is rather cubic (wider).FT (Front Terminal): Terminals are at the front. The block is very slim ("shoebox" design) and deep. Electrically the performance data is nearly identical, but the FT version is essential for 19-inch cabinets.Can I install the battery horizontally?Theoretically yes, but usually not necessary. The FT design is designed to be upright (standing on the floor) pushed into rack levels. This makes optimal use of space. Horizontal installation is possible thanks to AGM, but with this specific housing design rarely offers advantages.Do I need a special rack?Yes, or a suitable cabinet. The batteries are approx. 40 cm deep. Your rack or cabinet must accommodate this depth and the corresponding load (approx. 150 kg per level with 4 blocks). Standard network cabinets are ideal for this.

The difference is in the housing material.SWL4000: Standard ABS (UL94 HB).SWL4000FR: Flame retardant (UL94 V-0). The extra charge for the FR version is an investment in safety and often a requirement of building insurance.Do I need special tools for installation?You will definitely need insulated tools (torque wrench, spanner). With batteries of this size, a short circuit is extremely dangerous (arc, molten metal). Due to the M8 connection you need suitable sockets/spanner sizes.How many of these batteries fit in a cabinet?That depends on the statics. Because of the high weight (~48 kg) and height (275 mm), fewer blocks usually fit in a standard cabinet than in smaller types. Reinforced heavy-duty shelves or special battery cabinets are often required. Be sure to check the floor load (kg/m²).

The high manufacturing quality and the use of high-purity materials ensure constant performance and thus contribute to the high operational reliability of the overall system. Features  ModelSonnenschein A512/25 G5 ApplicationStandby / UPS / safety lighting TechnologyLead gel (dryfit®) Nominal voltage (V)12 Capacity (Ah)25 (C20) Design service life12 years (Eurobat Long Life) Dimensions (L x W x H in mm)167 x 176 x 126 ConnectionG-M5 (M5 internal thread) Weight (kg)approx. 9.5  FAQs about the Sonnenschein A512/25 G5 lead-gel batteryWhat is the main advantage of Dryfit® gel technology?The decisive advantage is the combination of absolute freedom from maintenance, maximum cycle stability and extreme longevity. Compared to AGM batteries, gel batteries are often even more robust against deep discharges and offer very constant performance over a long period of time, making them the premium solution for critical standby applications.What does the classification "Eurobat Long Life" mean?Eurobat is the association of European battery manufacturers. The "Long Life" classification means that this battery is designed for an expected service life of 10 to 12 years under defined standby conditions (usually 20°C ambient temperature and correct trickle charging).What is the difference between a standby battery and a starter or solar battery?A standby battery such as this one is optimised for standby parallel operation. It is permanently kept at a constant voltage (trickle charge) and only rarely has to release energy. A starter battery is designed for short-term, high currents. A solar battery (cycle battery) is optimised for daily, deep discharging and recharging.How should this lead-acid battery be disposed of?Lead batteries contain environmentally harmful substances and must not be disposed of with household waste. You can return your old battery to any dealer who sells new batteries or to municipal recycling centres free of charge to ensure that it is recycled properly.
