NOTES About the Ultralife U9VL 9 Volt Battery

The original model number for Ultralifes basic 9-volt battery is U9VL using a plastic housing. The U9VL was designed for applications in which the battery would most likely be used fairly quickly, such as in many medical, wireless security and music/audio devices.

The U9VL -J was the model number for our long-life 9-volt battery. It was actually a U9VL battery encased in an aluminum housing (or “jacket”). The aluminum housing reduces the amount of moisture that can enter the battery over time, which enhances its life. It is also slightly larger than the U9VL (U9VL-FP) battery, and presented a tighter fit in a small number of devices with smaller battery compartments that were originally designed to match the dimensions and shape of an alkaline 9-volt battery with more rounded edges.

Also, the U9VL -J was designed for applications in which the battery needed to last a long time, such as in smoke alarms, or where it may be exposed to low temperatures or uncontrolled heat and humidity conditions, such as in electronic parking meters or other outdoor applications such as automatic watering systems and dog training transmitters.

The U9VL -J-P is the current model number for our FIVE TIMES LONGER brand retail-packaged battery. It is a vast improvement over the U9VL-J model as the U9VL-J-P features a smaller package size than the ANSI 1604 standard for 9-volt batteries and is comprised of three series connected Ultralife Thin-cells, complete with intermediate shutdown separators for its internal construction. The U9VL-J-P is designed for applications in which the battery must either last a long time, such as in smoke alarms, or where it may be exposed to uncontrolled heat and humidity conditions, such as in electronic parking meters or other outdoor applications. You can get more information on our U9VL -J-P battery here.

The -FP, -BP, and –X suffices specify the different external packaging types, such as individually sealed foiled package, blister-carded package, or the ten-year smoke alarm/contractor blister-carded package. An advantage to the sealed foiled package is that it must be torn open to remove the battery, which easily verifies that the battery has never been used.
