How long do batteries last if unused?

Most unused alkaline batteries will last between five and 10 years, while Ni-MH batteries have a shelf life of three to five years of non-use. Lithium-ion batteries, which power devices like cell phones, have a low self-discharge rate and could keep a partial charge for up to four years before being depleted.

Do unused batteries degrade over time?

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. But even ideal storage conditions can leave you with a dead battery after three or four years.

Are unused batteries still good after expiration date?

Unfortunately, yes. All batteries have an expiration date mentioned on the packaging and on the cell itself. The battery may still work after that date, but with minor performance.
