What effect does temperature have on battery's life?

In Chul K,

Because the batteries to which you refer or likely to be those in common use, it is safe to say that all depend on various chemical reactions to produce electricity. The rate of chemical reactions is strongly temperature dependent, Thus, batteries (cells) will self discharge over time even it they are not being used. The self-discharge process can be slowed somewhat (but not stopped completely) if the battery (cell) is stored at a low temperature. It is better to keep them in a refrigerator rather than in a freezer -- and it is always a good idea to store them in an air-tight container. Often, shelf life can be greatly extended by this procedure. Also, be sure to allow the container and its contents to warm to room temperature before you open it. Never put a chilled battery (cell) inside the device it is intended to power until the battery (cell) is warmed up.


The output of most batteries are very dependent upon their temperature. The reactions producing the output fail rapidly as the temperature is lowered. This is why people who live in really cold climates -- frequently below 0 F. -- frequently keep their cars warm with electric heaters. The heaters also keep the oil and transmission fluids less viscous so that getting the car started does not require so much energy.
