Why batteries discharge more quickly in cold weather? If not in use why do batteries discharge more slowly in cold weather?

Explanation

When the terminals of the battery are connected, a chemical reaction is initiated that generates electrons to supply the current. Lowering the temperature causes chemical reactions to proceed more slowly. As a result, less current ins produces. consequently, they quickly reach the point where they cannot deliver enough current to keep up with the demand. i the battery is warmed up, again it will operate normally.
On the other hand, when the battery is not in use, it will slowly lose its charge due to leakage between the terminals. this chemical reaction is also temperature-dependent. so unused batteries will lose their charge more slowly at cooler temperature. thus, they may be refrigerated for longer life.
