Q: Battery cells keep dying
HELP! I am past frustrated!! Heres my "drama". I have just replaced my car battery less than 2 years ago. The battery I had to have replaced tested to have 2 dead cells even though was literally just out of warranty by a couple months. So now the replacement battery I bought is doing the same thing and its a 60 month battery. If I don't start it for 2 days, by the 3rd day its stone dead. I took this battery to be checked at local auto parts store. After they got it fully charged it tested that it was fine. I left it there til the next morning, they checked it again before I took it and SURPRISE....it had drained overnight from fully charged down to 4v! I have nothing whatsoever that is visible left on that might be causing this. Any suggestions of what could possibly be causing the cells to gradually die?? Any ideas or where to go next?
