Temperature and Battery Life
Name: In Chul K.
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
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.
