For UPS systems, the value "2450" is often more important than the pure Ah, as the battery has to supply an extremely high current within a few minutes.How can I recognise the FR version?The "FR" in the name and the inscription "UL94 V-0" on the housing are decisive. Visually, FR housings from Yuasa are often grey (standard is often black), but always rely on the nameplate. In public buildings, FR is often compulsory.Can I use the SWL+2450FR as a replacement for a 75Ah battery?Yes. The dimensions (approx. 350mm length) are usually identical to the standard 75Ah blocks (e.g. NPL78-12). By replacing, you get an upgrade to 80 Ah and higher high-current capacity without having to modify the cabinet.

The Yuasa SWL+4000FR is the ultimate energy solution for high-security areas. It combines the massive capacity of 135 Ah and the extreme power density of the SWL-Plus top models with a housing of the highest fire protection class (UL94 V-0).This 12-volt block was developed for use in hyperscale data centres and critical industrial facilities, where two factors are non-negotiable: Maximum availability (performance) and maximum building protection (safety). With a unit weight of almost 50 kg, this battery is a pure powerhouse that supports megawatt loads and is designed for a service life of 12+ years.Highlights at a glanceFR safety housing (Flame Retardant): The housing is made of flame-retardant ABS plastic in accordance with standard UL94 V-0. In the event of fire, the material self-extinguishes and prevents flaming dripping. This is often the basic prerequisite for insurance cover in server rooms and public facilities.Maximum capacity (135 Ah): With 135 Ah this block offers enormous energy reserves. It enables long autonomy times in UPS systems, without the need for complex and maintenance-intensive 2-volt cell systems.Ultra High Rate Performance (4000 Watt): The indicator "4000" stands for the extreme wattage per block. The SWL+4000FR is designed to safely handle the enormous inrush currents and load peaks of modern IT infrastructure.Eurobat "Very Long Life": Classified for a service life of 12+ years (design life up to 15 years). This guarantees investment security and minimises maintenance costs for more than a decade.HT Element X technology: The patented hybrid alloy of the grid plates minimises internal corrosion and makes the massive block resistant to uneven ageing and temperature fluctuations.Maintenance-free & Safe: VRLA-AGM technology (Absorbent Glass Mat). The electrolyte is bound, the battery is leak-proof, low-gassing (internal recombination) and does not require topping up with water.Areas of applicationThe SWL+4000FR is the standard choice for heavy-duty applications in sensitive areas:Data centres (Data Center): Maximum power with maximum fire protection.Large UPS systems: Banks, insurance companies, hosting providers.Telecommunication: Central switching stations (Core Network).Energy suppliers: Buffering in power stations and substations.Safety lighting: Large central battery systems (ZSV).Installation & safety instructionsCritical weight: A single block weighs almost 50 kg. Installation must never be carried out alone ("two-person lift" or lifting equipment). Pay strict attention to the point load of your raised floor in the data centre!Connection (M8): In the event of a short circuit, currents of several thousand amperes flow here. The M8 bolts must be tightened to 6 Nm. A loose contact can immediately lead to massive heat generation at this power.FR compliance: Never replace an FR block with a standard block, as this downgrades the fire protection class of the entire string ("chain").Ventilation: Adequate ventilation of the battery room in accordance with EN 50272-2 is mandatory.Features  ModelYuasa SWL+4000FR (Flame Retardant) Housing Specification**Flame retardant** according to UL94 V-0 (Highest safety standard) Voltage12 V Capacity**135.0 Ah** (Ultra High Capacity) PerformanceMaximum performance for 12V monoblocks 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 (Massive block!)

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).
