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.

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
