TRUE OR FALSE : Cold weather is bad for batteries.
FALSE : Batteries like the cold. Lower average battery temperature means longer life expectancy. A typical baggage tractor battery weighs well over 3,000 pounds, which is too much mass to lower the internal temperature over the course of a day or two. Hopefully, the battery is being used and charged, which generates heat and maintains temperature. And even if the internal temperature drops, the electrolyte in a charged battery will not freeze. So in most cases, even freezing temperatures don’t make any difference at all, and possibly they even help.
There is some bad news, however:
Lower internal battery temperature means lower capacity : A cold battery could deliver as...
