Batteries 101: Battery Care

How does proper or improper charging or storage impact the life of rechargeable batteries? Learn some helpful tips on the best way to store, handle and care for your rechargeable batteries, whether at home, work or at play.

Additional Do's and Don’ts for Rechargeable Batteries


  • DO follow the manufacturer’s directions carefully for battery storage and care, and don’t overcharge batteries.
  • DO charge your battery at room temperature (68°F to 72°F) to extend battery life. Batteries get warm during charging and use—this is normal. As a precaution, most batteries and chargers are designed to protect against overheating.
  • DO remember to recharge your battery a few hours before you want to use it. Rechargeable batteries lose a percentage of their charge each day when left off the charger.
  • DO keep battery contact surfaces clean by gently rubbing with a clean pencil eraser, cloth or rubbing alcohol. Dirty contact points are a primary source of charging challenges.
  • DO use only chargers designed for your type of batteries. If unsure about compatibility, contact the product manufacturer.


  • DON’T leave your rechargeable batteries discharged or unused for extended periods of time. To extend battery life, charge them at least every 6-9 months.
  • DON’T recharge a battery unless it is specifically marked “rechargeable.”  Attempting to recharge a primary (non-rechargeable) battery could result in leakage or rupture.
  • DON’T use rechargeable batteries in chargers that are not designed for the specific battery type.
