Putting batteries in the fridge or freezer
A lot of people are unsure whether this is actually fact or myth and it is kind of both. Things tend to get too generalised and this often leds to misconceptions that people will overlook and just assume it worked.
Most common household batteries are NiMH (nickel-metal hydride), NiCd (nickel-cadmium) and alkaline. The facts are that unless alkaline batteries are being held at a very high storage temperature to begin with then chilling them will make very little difference.
NiMH and NiCd batteries on the otherhand will discharge alot quicker. This is often apparant in recharable batteries that have gone on charge but not been used straight away. Freezing the batteries will retain a substancially larger amount of the overall battery life.
Always make sure to store batteries safely and to only use batteries in electronics at room temperature.
