Longest lasting 9V in critical applications

The new Ultralife lithium 9-volt battery is a fully compatible alternative to standard 9V batteries that lasts up to 5 times longer than ordinary alkaline and 10 times longer than zinc carbon equivalents.

It has the highest energy density, flattest discharge voltage curve, longest shelf life, widest operating temperature range, and lightest weight of any comparable 9-volt battery.

This and its 10-year service life make it ideal for many critical applications such as premium smoke alarms and medical devices.
