Can batteries be left in the cold?

One of the common laws of chemistry is that reactions generally speed up when they get warm and slow down when they get cold. Such is the life of a battery. The problem is not with storing batteries in the cold, but rather trying to use them when they are cold.
A.

How does cold weather affect alkaline batteries?

In general, alkaline batteries perform very poorly in cold weather. As alkaline batteries are engineered with a water-based electrolyte, cold near-freezing point temperatures can lead to reduced ion mobility which slows down the chemical reactions that provide electrical battery power.

B.

Do batteries work better in the cold?

Batteries are a function of chemical reactions. In cold weather the chemicals can not react as fast as in warm. In fact keeping a battery cold will extend the life of the battery, by slowing the chemical discharge. A cold battery may still be good but will not have the same the power as a warm one.
  • Do car batteries freeze?

    But if a car battery is discharged because of damage to cells, poor connections or a charging system that isn't doing its job, the battery could start freezing at the same temperature as water at 32 degrees Fahrenheit.
