Is there any way to tell if a dead battery was defective or if I have an electrical problem.
In March I installed a brand new battery. Last week I drove the car on Tuesday. Started right up no issues. Friday AM I went to get in it and it was dead as a doornail. Could not even open the rear hatch, no lights or sounds at all. Had to jump it just to get the hatch open. I had recently bought a CTech charger from a forum vendor so I connected the charger Friday AM and left it on until Sunday evening.
The charger indicated it was charging but when I disconnected it the battery was still absolutely dead.
Any suggestions for things I can check myself?
I had similar issues with my car as well....I did some research and decided to put in an Interstate Megatron Plus 75 series battery and have not had a problem yet. Battery was installed December 2010
Hope this helps!

Because the battery was new, I would take it back and get it replaced under warranty. Once the new one is installed, you can see if you have a draw somplace. hopefully the place you bought the battery from can test it under load and tell you if it was bad or not.
