why is it, that you would put battries in the fridge...?

Question

but the cold would drain your battery? when i went skiing, my batteries were dead in less than 24 hours and i wasn't using it.

Answer 1

People put batteries in the fridge because cold slows down chemical reactions. Since batteries convert chemical reactions into voltage, slowing the chemical reaction is supposed to preserve the battery. That is why using batteries in cold weather doesn't work well, the chemical reaction slows and the batteries don't work well.

Answer 2

I think its mostly a myth about refrigerating batteries. Batteries are technically cells. Chemical reactions occur to create the electricity and cold temperatures slow reactions.

Duracell even says not to put them in the fridge because it won't make them last longer.

Answer 3

Its an interesting phenomena with alkaline batteries. Put dead batteries in the freezer, and they recharge themselves to around half charge. Strange but true. Cold makes electricity work better, molecules are closer together, doesn't require as much power to move current.

Answer 4

putting a battery in the fridge will not recharge the battery. when the battery is dead, that's it. there is nothing you can do to bring it back to the original state. putting it in the fridge will give you a little power if the battery is dead, but it won't last.

Answer 5

Don't wait for them to die. Putting them when you get them is good. Cold things always slow down. It preserves their power.
