Many people are opting for zinc-air button batteries, also known as button batteries. These air-activated rechargeable batteries can remain inactive until removed from their factory seal and peel away revealing a chemically reactive surface where oxygen is able to react with the zinc in order to activate these powerful devices.

When performing at its peak, these battery types should be used right after activation but unlike alkaline cells that continue functioning at lower levels over long periods of time, if not used soon after being inserted into your device, the performance level will quickly diminish. To avoid this problem altogether you should store them in a protective case.

Researchers have found that zinc-air batteries can last up to three years when stored in the appropriate environment. You might be surprised to know that storing them in a refrigerator may actually reduce their lifespan because condensation will form under the sticker and could cause corrosion.
