Energizer® e2® Lithium AA Batteries

Unleash the power of the world's longest lasting AA and AAA batteries in our high tech devices!

Lithium batteries are designed differently than alkaline batteries. Energizer® Ultimate Lithium batteries are built in a spirally wound construction. This design helps the battery meet the high current drains of many of today's devices.

Lithium batteries are ideal for outdoor temperature sensors. They can withstand extreme temperatures and they last longer so replacing the batteries is less frequent.
