Use an electrical meter to measure voltages. The battery should be 12.75 volts when the car is off, the voltage at idle should be about 14. You can also take the battery to an auto parts store and they will test it for you - if its not up to par, you at least have a prorated warranty, if your within the first year you may get a free exchange. I ran a standard interstate battery for about 18 months before one of the cells went dead, I got a nearly free replacement but instead upgraded to their premium battery for a few bucks more. Primary sources of battery drain overnight are the door lock module, and possibly the lights in the doors if the switch is not properly adjusted. A battery cut off switch is easy to install if you leave the car parked for a week or two at a time.

After the car sits overnight, you get in the next day and try to start it. Turn the key, the engine cranks and begins to start, then it sputters and dies out. Try to start it again the same thing happens until it just won't turn over at all. After only 4-5 tries in a 1 minute timeframe, the battery is dead and turning the key just makes it go CLICK CLICK CLICK. If I jump the battery onto my other car the Delorean starts right up. I find it hard to believe this is a battery issue though alone since I have an Interstate battery that is 1 year old and I'm in a warm climate. Anyone think it could be electrical related...maybe something is grounding out and draining the battery overnight? Or could it be engine related?
