Yuasa Lead-acid battery with 6V and 1.2Ah - NP1.2-6

Description

Product information

The Yuasa NP1.2-6 is a particularly compact, valve-regulated lead-acid battery (VRLA) with 6 volts and 1.1 Ah capacity. It is ideal for devices with low energy requirements where a constant, reliable power supply is needed, for example in safety and measuring systems. The battery is maintenance-free, robust and designed for a long service life.

Highlights at a glance

  • Compact capacity: 1.1 Ah at 6 V – ideal for energy-saving systems.
  • Minimal space requirement: Only 97 × 25 × 54.5 mm – fits into the smallest installation spaces.
  • Flexible installation: Operation possible in all positions, except permanently upside down.
  • Maintenance-free: VRLA technology with integrated low-pressure exhaust valves.
  • Long-lasting: EUROBAT class “Standard Commercial” – up to 5 years in use.
  • Safe design: Robust ABS housing, optionally flame-retardant.

Small battery, great reliability

With its capacity of 1.1 Ah at a 10-hour discharge up to 1.8 V/cell (at 20 °C), the NP1.2-6 provides a stable power supply for applications with low current requirements. The high discharge current of up to 36 A for 1 second also makes the battery suitable for short-term power peaks.

Robust technology with a long service life

The NP1.2-6 is maintenance-free and designed for durability. It complies with the EUROBAT classification “Standard Commercial” with a service life of up to 5 years at 20 °C. The low self-discharge rate of approx. 3 % per month guarantees high operational readiness, even with longer storage.

 

The housing is made of impact-resistant ABS (UL94:HB), with an optionally available flame-retardant version to UL94:V0. The battery also meets the requirements of ISO 9001.

Easy integration and safe handling

Thanks to its compact dimensions, the NP1.2-6 can be flexibly integrated into existing systems. Installation is possible in almost any position as long as it is not operated permanently upside down. The Faston plug connections (4.75 mm) enable quick and secure connection.

 

Each cell has a low-pressure exhaust valve that opens when necessary and then automatically closes again for safe, low-maintenance operation. For floating charge there is no limit to the charging current, for cyclic operation the recommended limit is 0.3 A.

ULT9VLJP10
Ultralife 9V lithium battery U9VLJP10 (U9VL-J-P) 1200mAh (pack of 10 / foil)

The Ultralife U9VLJP10 is the economical bulk package (bulk pack) of the proven U9VL-J-P 9V lithium battery. This set contains 10 pieces of high-performance batteries, mostly in space-saving foil packaging instead of individual plastic blisters. This variant is aimed specifically at professional users, janitorial services, hoteliers and installers who need to service a large number of smoke detectors, security sensors or medical devices at the same time. Technically, the cell is identical to the retail version: it offers up to 10 years of service life and maximum reliability.Highlights at a glanceValue pack (10 pieces): Supplied as a 10-unit package (often foil-wrapped or in an industrial carton), which reduces the price per battery compared to individual blister packs and reduces packaging waste – ideal for large projects.The smoke detector standard: Enables up to 10 years maintenance-free operation in compatible smoke detectors, which drastically minimises maintenance effort in rental properties and commercial premises.High energy density: With 1200 mAh, it offers huge reserves for long-term use and lasts up to 5 times longer than conventional 9V alkaline batteries.Long shelf life: Thanks to the very low self-discharge, you can easily store this 10-pack for up to 10 years without the batteries losing significant performance.Wide range of applications: Works reliably at temperatures from -20°C to +60°C, making it the first choice for unheated warehouses, attics or garages.Safety construction: The housing is robust and leak-proof; the lithium manganese dioxide chemistry is non-toxic and contains no cadmium, mercury or lead.The solution for facility management & large installationsThe U9VLJP10 is the standard choice when entire buildings need to be equipped with new batteries. Whether during the annual replacement in hospitals (pagers, monitors), in hotels (electronic door locks, safes) or in apartment buildings (smoke detectors): The bulk pack saves time when unpacking and is kind to the budget. Features ModelUltralife U9VLJP10 (industrial pack / foil) ApplicationLarge scale users, facility management, OEM (less waste) TechnologyLithium manganese dioxide (Li-MnO2) - primary cell Voltage9 V (Nominal) Capacity1200 mAh (constant to end of life) Packaging unit10 pieces shrink-wrapped in foil (bulk) Dimensions (L x W x H in mm)48.5 x 26.5 x 17.5 (standard 9V block) Shelf life10 years (ideal for long-term smoke detectors) Temperature range-20°C to +60°C Special featuresCost-efficient bulk package, more environmentally friendly (less plastic) Weight (g)approx. 37 (per battery)  FAQs about the Ultralife U9VLJP10What is the difference to the U9VLJP-BP?There is no technical difference in the battery itself. BP = Blister Pack (individually packaged for retail sale). 10 (or FP) = Foil Pack / Bulk (10 pieces packed together for industry). The U9VLJP10 is more environmentally friendly (less plastic waste) and usually cheaper per item.Is "round cell" the correct term?Your enquiry mentioned "round cell", which is a common misunderstanding. The U9VL is a 9V block (rectangular, prismatic). Internally, it consists of three flat cells (not round cells), but the design is the classic "E-block". Ultralife also manufactures real round cells (like the ER14505 AA), but the designation U9VL always refers to the 9V block.What happens if I store the batteries?Almost nothing. That is the great advantage of lithium. You can buy this 10-pack, take out 2 batteries and put the remaining 8 in a cupboard for 8 years. If you need the remaining 8 batteries then, they will still have almost 100% of their charge. Store them ideally in a cool, dry place.Are the batteries packed short-circuit-proof?As a rule, the batteries in the pack of 10 are supplied so that the terminals cannot touch each other (e.g. by a plastic cap on each battery or a tightly fitting foil). Important: If you open the pack and put loose batteries in a drawer, be sure to tape the terminals or leave the protective cap on. If two 9V blocks touch at the terminals, a short circuit immediately occurs (fire hazard!).
