Special featuresEnvironmentally friendly (less waste), quick handling, leak-proof Weight (g)approx. 7.6 (per battery) FAQs about the Energizer L92 in a box of 10Are these batteries different from the ones in the blister pack?No, technically they are identical. This is exactly the same Energizer Ultimate Lithium L92 cell. The only difference is the packaging: instead of being individually shrink-wrapped in plastic and cardboard, the batteries are loose in a small cardboard box. This saves space and waste.What is the best way to store the opened box?Cool, dry and short-circuit proof. As the batteries are loose in the box, make sure that no conductive objects (paper clips, coins) fall into the box. If you remove individual batteries, close the box again. Thanks to the lithium technology, you can easily store the box in a cool cellar or storage room for up to 20 years.Is the box of 10 cheaper?Usually yes. As the manufacturer saves the cost of the complex individual sales packaging (blister pack), this price advantage is often passed on to the customer. The "unit price" is usually more attractive for bulk goods than for blister packs of 4.Is this pack worth it for VR controllers?Absolute. Modern VR controllers (e.g. Oculus/Meta Quest) require a lot of energy and benefit enormously from the low weight of lithium batteries (faster hand movements, less fatigue). As you usually have 2 controllers and play intensively, the 10-battery supply is very useful here.

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!).
