Datasheet

The next-gen of Ultralife Corporation's long lasting lithium 9V battery, the U9VL-J-P, has been released. With key improvements to its energy density and cell technology, the battery is designed for applications including smoke detectors, security sensors and medical telemetry as well as test and instrumentation.

Launched in 1991, the original battery has sold over 100m units worldwide. The next-gen battery builds on this success, using a lithium-manganese dioxide chemistry, which delivers a stable discharge and high energy density.

The U9VL-J-P weighs 37g and conforms to the dimensions of ANSI 1604 – the same size as a standard 9V battery. Thanks to the use of Ultralife ThinCell technology, where three individual thin foil cased cells are combined to create a 9V battery, it achieves a capacity of 1200mAh. Ultralife claim that this is 50% more energy than the 800mAh capacity boasted by the leading brand-named lithium competitors and five times the energy of leading alkaline 9V batteries.

"As we've seen from recent reports in the media, high energy lithium batteries can pose a risk of fire when things go wrong," explained Bernd Rosati, European Sales Manager at Ultralife Corporation. "To make it the safest battery possible, the U9VL-J-P is constructed with a shutdown separator and a temperature and current (PTC) safety device.

"We've also reduced the battery's internal impedance by enhancing its design. This means that it can supply a higher power output with a stable voltage. This is great for demanding applications such as security systems, telemetry products, smoke or carbon monoxide alarms, test and instrumentation and medical devices where a high-pulse current improves operation."

The Ultralife lithium 9V battery offers a shelf life of up to ten years, even in tough environments. The battery has an operational discharge temperature between -40 and 60°C, making it a useful long-life battery for indoor and outdoor use.

The U9VL-J-P complies with Underwriters Laboratories' UL1642, UL2054 and UL217 specifications, features a non-magnetic structure and qualifies for several exceptions under Class 9 shipping regulations. The battery is also available in various packaging including a blister pack, a bulk pack and a foil pouch as well as a version for contractors.
