Battery goes dead when temperature hits 90+ 850 1995

For the past two summers my battery has gone dead when temp goes past 90 degrees f. She jump starts, and the battery will hold a charge when disconected. What is draining the battery when it remains connected? It is an Interstate battery, and it is/has been replaced under warranty. I've had no problems except during the heat of summer.

Its hot. This sounds normal. How many CCA is your battery? Here in FL anything lesee than 800 CCA will not turn my car over when its 100+. Heat is harder on a battery then cold.

The battery cranks and starts fine when connected to drive and holds its charge when disconnected. It gets drained if it is not disconnected,(and it gets drained quick, less than 1 hour) I'm in Indiana and this problem only happens in the summer when temps hit 90+. The electric fan does not switch on, the glove box light is disconnected, I suspect there is some relay/switch that keeps a circuit, but what I don't know. I was hoping this might have been a common problem with '95 850GLTs

Connect a ammeter to the the battery and when the temp is 90+ you should get a current flowing. this will let you know that something is draining it.
