Do batteries not yet in use (AAA,C,D, etc.) last longer when stored in the cold or at room temperature?

Answer 1

They will last longer when stored in a cool environment until required for use.
At higher temperatures the self-discharge increases and the shelf life is reduced.

Answer 2

any eqipment,any electrical ayastem designed to work in room temperature,batteries are consist of chemical substances reacts with each other inside to generate electrical power,when temperature became lower than room temperature this reaction reduced then the output power became lower,but you will not recognize this difference by using them in radio or any other electrical system.

Answer 3

room temperature.....remember how car batteries get weak in really cold weather?
