AGM Batteries
 

Anyone have any problems with heat from the engine compartment affecting AGM batteries? I read that they don't like a lot of heat?? I'm looking to purchase a dual purpose AGM but want to be sure it will work OK.

There should not be enough heat to affect agm batteries, Have been running them for 20 years in boats, cars, race cars, atv's and my seadoos. I see up to ten years life on my boat batteries.

What AGM batteries have you been running in the boat? I wanted to buy new ones this year.

Thanks

I'm going to buy the Duracell battery from Sam's Club. It's a Deka battery and I have read all good reviews. Plus it's made here in PA!

Optima Blue tops for the boat

I run a Braille AGM in my Ferrari 550 plent of heat soak in it during Florida summers. I also use them in raceboat no problems at all.

I was looking at the Sears Platinum AGM Batteries over the winter. I looked at them again the middle of last week. The group 31's were about $217 on sale if I remember correctly. I looked again today and they are $260. I MISSED THE SALE!!!!! I knew I should have bought them LOL I

I have a Duracell in my Kubota. More than 10 years old and I beat the crap out of it - dead in the winter, jump start the hell out of it, etc. Never had one but would try it again.

have been running AGM batteries for years, no issue with heat at all. As a matter of fact one of my AGM batteries is on its 5 year and still going strong.

x2 on the Blue's.

The pair in my boat are from early 2007 and still going strong. Have been deep cycle drained at least once "left radio on for a week." I connect a battery tender to them during winter storage and that's it. Also noticed them under the hatches of a few race boats last weekend...

If anyone is looking for Sears Platinum batteries, Sears has 25% off today. I just purchased 2 group 31 Sears Platinum batteries on sale for $217 each, plus if you enter 20AUTO in the discount code you get another $20 off each transaction. I did 2 transactions (one for each battery) to save an addition $40.
