With a lithium chemistry, this battery offers twice the voltage of alkaline and silver oxide coin cells, making it last longer in your devices. Plus, with a 10 year shelf life, you can keep spares in your house and feel safe in knowing they'll be in perfect shape to use.

Due to the lithium chemistry of this battery, it is not rechargeable.
