How to Store AA Batteries
Properly stored batteries will last longer and be ready for use when you need them, but if not correctly kept, the lifespan of batteries decreases rapidly. Some myths exist about storing AA batteries, and some people confuse them with battery storage tips for computer batteries, but the different chemical composition of AA alkaline batteries requires a unique storage situation from other types of batteries. Never be without power again when you keep your batteries correctly.
Things You'll Need
- AA batteries
- Pencil eraser
- Resealable storage container
- Permanent marker
Remove the AA batteries from the device for long-term storage.
Take out alkaline batteries from battery-operated devices working off of AC power.
Rub an eraser over the battery contact nodes in the appliance and on the battery to prevent buildup on the site (Reference 3).
Keep alkaline AA batteries in the original container until ready to use, if possible.
Place the batteries in a resealable container with a label on the front marked with the date of storage. Do not mix older batteries with newer ones in your appliances.
Keep alkaline AA batteries at room temperature for up to five years, but do not put them into the refrigerator or freezer. Avoid extreme temperatures for AA battery storage. Cold batteries do not operate with full power, and AA batteries stored in hot places have shorter lifespans (Reference 2).
