High-Performance Batteries in Batteries(744)

What battery size is most commonly used in homes?

Double A (AA) is the most common size battery found in homes, so you may want to keep some extras on hand. If you have devices that use AAA (remotes), C (radios), or D-batteries (flashlights), stock up on those sizes, especially if you live in an area with extreme weather that causes power outages.

Where should I store batteries in my home?

Store unused batteries in their original packaging or wrap a rubber band around them before placing them in a plastic bag. Keep them away from extreme temperatures (including the freezer) and moisture. It’s a good idea to remove batteries from items that you won’t be using in the near future to prevent corrosion and leaking.

How long do household batteries last?

Batteries have a cycle life (how long it lasts after you start using it) and shelf life (how long it will hold a charge). The cycle life depends on several factors, including the battery’s size and type of device it's powering. Some devices drain more of the battery than others, and batteries from some manufacturers last longer than others. Alkaline batteries can last for up to 10 years when stored at room temperature and away from humidity. Carbon-zinc batteries have a shorter shelf life, between 3 and 5 years.
