Fact or fiction about life of batteries in hot areas
Just curious...I was told yesterday that batteries in cars/trucks only last about 5 or 6 years in AZ heat. "Sitting in hot weather cooks them and shorten their lives". Fact or fiction?

extreme heat or cold will reduce battery life.
Not true. If they do not actually freeze, cold increases the overall life of a battery. The capacity will be less WHILE it is cold however.
And yes it is true that batteries age faster when it's HOT. The chemical reaction goes faster.
As for the 5 or 6 year number: Too many other variables to call that one.
