CR2430 battery: storage life

CR2430 is a lithium coin cell. Storage life is how long a cell holds power while unused.

This page reports the Energizer United States product page. Other makers and other regional pages publish different figures.

The Energizer product page for the CR2430 says it holds power for 8 years in storage.

Limits of this figure

Energizer Australia lists up to 10 years for some coin cells, and the Energizer lithium coin handbook says 10 years at normal room temperature. Brand and region change the figure.
