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?

As always, these type discussions always seem to assume liquid (wet) acid batteries. AGM (dry) batteries are a whole different animal.
And as always, some seem intent on ignoring the simple original question and running off on a tangent.
High temperatures adversely affect ALL batteries, some to a different degree. AGMs last longer in almost all circumstances but it has little or nothing to do with resistance to temperature extremes.
So, the original question was: Will batteries fail sooner if exposed to high temperatures? And the answer is a resounding YES.
The only exception might be a "dry charged" one that has not yet been activated by adding electrolyte. But then it is not a real battery......yet.
