Grid heater in the summer

From : john

Q: now that i live in the arizona desert i have a question about the grid heater. during the summer it regularly gets to well over 100 degrees up to 115 sometimes. cooked batteries are a common problem here. the grid heater obviously isnt needed during the summer months here. does that heater always come on or is it thermostatically operated i was thinking of disconnecting it or maybe even putting in a switch to keep it off during the summer. giving the batteries a break during the summer seems like a good idea. any opinions john .
