Do you have a way to measure the switch off current drain? should be less than 100 milli-amps but 60-80 milli-amps should be great. You can even measure it with one of the cheap-o or free meters from Harbor Freight - just might have to disconnect the under the hood light while checking it. Disconnect the one of the battery terminals and put the meter in line in the current mode. Probably can google it and find a good description on how to connect it.

While you're measuring the current if you open a door and the interior light will come on and most likely blow the fuse in the cheap-o meters so be sure and only measure with everything off.

This is a clamp on version - was measuring current output on the Tbird generator so that's much higher reading 24.7 Amps.

Also possible that your battery has a shorted cell - it will charge and work under most conditions but any extended draws (even small ones) will make it loose capacity quickly.

Just some ideas - Eric

edit - looks like a decent article about finding "leaks"
Thanks Eric. I'll hook up my multi-meter this weekend as you suggest. If there's a leak, I wouldn't know where to begin to trace it down. If no leak, I'll truck down to the local "Bull Dog Battery" to test the battery. The funny thing was the last time this happened, the extra key fob battery kept 6 feet from the car was shot, also.

I bought my T-Bird battery at this same place and was offered the choice to skip their logo on the side of their battery. That came in handy so I could place the Power Punch decal that no one sees on the new battery.
