Do Lithium Batteries Have A Shelf Life. Lithium batteries can do that no Im not kidding. The following guidance is based on batteries that are kept at the right temperature the right humidity and in the correct State of Charge.
Batteries have three distinct measures of life run-time shelf life and cycle life and each type of battery chemistry has a different answer alkaline lithium-Polymer etc. The top rated best Lithium Ion AA double A or L91 and AAA triple A or L92 batteries have a shelf life of 20 years and active usage of up to 10 years. Energizer MAX AA AAA C and D cells last up to 10 years in storage while our 9V lasts up to 5 years in storage.
Lately I have been looking for lithium ion batteries with considerably longer shelf life - for power-wall like applications.
The top rated best Lithium Ion AA double A or L91 and AAA triple A or L92 batteries have a shelf life of 20 years and active usage of up to 10 years. As I said these will do for 90 of applications but if you do need more power for a particularly high drain device then look for lithium-based batteries they will outperform these amazon basics but expect to. You might find that many manufacturers choose battery chemistry based on how the device is used. Alkaline batteries seem to have a typical shelf-life of 7-8 years but I am guessing anything similar cannot be said for Li-ion.
