AGM batts-how hot can they take
I have two AGM batteries in wooden boxes. They are right next to the exhaust of
a 85 hp perkins. This is the second set to "die" an early death. How sensitive to heat are these. If in a well vented box of 3/4 marine ply that is sealed with epoxy and painted, with a lid. How hot could the exhaust get the bat. Real distance from the bat is 1" inside, then the 3/4"ply, then 4 to 5 " to the mainiflold. I want to stay with the AGM but never had this problem with the wet batts. I will add heat and sound sheilds into the area if I have to but it is crowded there already. Thanks Bob |

Does your charge have provision for a temperature sensor on the battery?
If not then the higher temp of the batteries will result in overcharging. Overcharging a wet battery just leads to water loss (unless it is extreme). Overcharging an AGM will quickly destry it.

Yes the charger is temp sensitive. I am more concerned about the heat of the
engine regarless of charging. I know charging temp is important to the ultimate best charge but I am more intrested in the survival aspect |

I suppose you can get some spec from the manufacturer dealing
with storage temperatures. Battery temperature is much more important than getting the ultimate charge. As I said earlier, overcharging an AGM is the leading cause of battery failure. Other than that, they are very rugged. I believe that AGM are used inmost military vehicles and many aircraft in general. The environments they are used in can get very hot and very cold.
