The best temperature to store a rechargeable battery is around 60 degrees Fahrenheit. As they sit around, they start to lose some of their charge. This is called self-discharge, and it refers to the battery losing capacity without being used. Different types of power cells have different self-discharge rates. The ones containing nickel discharge fastest. This means that any Nickel-Metal Hydrate or Nickel-Cadmium rechargeable battery will self-discharge slightly faster than other types.
