Do batteries lose their charge?
Solid Electrolyte Interface and Electrolyte Oxidation
As your battery continues to cycle, it gets thicker. Eventually, it prevents interaction between ions and the composite materials of the electrode so batteries lose their charge.
Do batteries wear out if not used?
And batteries degrade even if you don’t use them. According to battery-testing firm Cadex Electronics, a fully charged lithium-ion battery will lose about 20 percent of its capacity after a year of typical storage.
Do old unused batteries lose their charge?
Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases.
