How to store batteries?

There are some best cases to keep stored batteries in best shape.

  1. If possible store batteries in their original packaging. That way you are always sure they are not over date and this also provides a way to keep track of purchased batteries. Also this prevents mixed use of older and newer batteries, which could possible lead to leakage or malfunctioning. And finally keeping them in the Original package prevents the batteries for external short circuiting and oxidation.
  2. As stated above never mix up different batteries, and keep all types/ grades batteries stored separately, this can prevent accidental short circuiting.
  3. Store the batteries at room temperature or in a cool environment, but please avoid high humidity and direct sunlight. Ideal storage temperature is 10C° - 25C° in a dry environment.
    1. Too high temperatures ( +35C°) should be avoided, it can influence the level of self-discharge (high storage temperature increases the amount of self-discharge). 
    2. High humidity should be avoided, for it may cause condensation on the batteries, which could cause short circuiting.
    3. In theory cold storage temperatures are good for the battery however, if stored i.e in a refrigerator there is a very high risk of condensation and thus malfunctioning of the battery. Also if the battery is stored in cold environment it should be kept at room temperature for at least 24h before using it.
