What is the Energizer^® e^2® Lithium's temperature range?
Energizer e² Lithium batteries work well in a wide range of temperatures, from -40°C to 60°C.

Is lithium safe for the environment?
Yes. Much of the concern with the environment centers on heavy metals. Lithium is the lightest metal known.

Can you mix Energizer^® e^2® Lithium batteries with Energizer^® e^2® batteries?
No. You should never mix different battery chemistries. Different battery chemistries discharge differently in a device, which could potentially lead to premature battery failure of the lower capacity battery.
