cobra_280z Posted July 30, 2007 Share Posted July 30, 2007 IN the last two months, my car has killed three different brand new batteries. The car seems to run fine for about a week or so, but then i will see the voltometer markedly drop. The car still starts fine, but when i take it in to do an alternator/battery test, the test always says that the battery needs to be replaced; the alternator is new and always tests fine. I do have an aftermarket stereo system, but it is functioning perfectly; also, i have run this stereo on a battery of equal strength with no problem for the past two years. I figured it might be a bad ground or connection, but can't seem to find anything. Any ideas or suggestions would be greatly appreciated. thanks.

280zwitha383 Posted August 1, 2007 Share Posted August 1, 2007 Well, I would question the people doing the testing really. The first thing I would do is see if anything is pulling the batter down (which something probably is): http://www.international-auto.com/index.cfm?fa=ad&aid=331 Quote Link to comment Share on other sites More sharing options...
