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?
Forum Discussion
As always, these type discussions always seem to assume liquid (wet) acid batteries. AGM (dry) batteries are a whole different animal.
This past summer I replaced two AGM RV batteries that were about 8 years old that still seemed to have plenty of life left in them ... they were kept on a maintenance charger 24/7 when not in use.
I have a larger (Group 31, 95 amp hour) yellow top Optima AGM battery that is at least 15 years old and it will still start our car ... I top up it's charge only a couple of times a year.
Finally .... after owning our 4X4 PU for 18 years .... this past summer I put an AGM starting battery in it because I got tired of replacing liquid acid batteries that continued to let me down after being in the truck only a few years.
You can replace a bunch of liquid acid batteries or replace only a very few AGM batteries.
