I have put 7 batteries on my 2005 Avalanche in the past 18 months, 2 in the past 2 months. My local Chevy Dealer can't find anything wrong with it. I then carried it to a local Alternator/Starter Shop and they couldn't find any problem. I need help.

check the battery for a draw after the key is off. the DIY section covers how to do this. alot of times it's the abs unit that goes bad by a transistor inside of it. These canberebuilt and the problem is fixed as they use a larger transistor. Especially if this happens overnite it may be the abs.
