How long do batteries last if not being used?

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.

Can batteries expire before use?

Q: Do batteries expire? A: Yes, all good things must come to an end. To find the Best If Used By (BIUB) date of the batteries in question, please look on the uppermost section of the cells, near the battery type (AA, 9V, etc.). You will see a white box with the Best If Used By year printed within it.

Should you take batteries out when not in use?

DO preserve battery life by switching off a device and removing the batteries when it's not being used, and is not expected to be used for extended periods of time. DO practice proper battery storage by keeping batteries in a cool, dry place at normal room temperature.

Do battery expiration dates matter? Battery Rundown Tests

What happens when batteries expire?

When a battery is expired, it means that the battery's manufacturer can no longer guarantee that the battery has a full life or charge. More specifically battery expiration dates are based upon when the battery's total self-discharge will exceed 20%.

Why do batteries expire?

Expiration dates mostly mean that the manufacturer will not guarantee that the batteries will perform at peak levels after that time. Batteries create chemical reactions that flow back and forth releasing energy to power your devices, but they can run out due to lack of electrochemical actions.

What is the proper way to store batteries?

Why do people put batteries in the fridge?

Some people swear by storing their batteries in the refrigerator to extend the lifespan of the battery and keep them fresh (apologies for the obvious food-storage joke).
