backfoot100 Posted March 12, 2008 Report Share Posted March 12, 2008 I agree with the point that the battery may be bad. I've had brand new batteries lose a cell after 12 months. That's why you have warranties (60 month, 72 month etc.) on these things. If they do go bad, they are normally pro-rated after a certain time frame. Also verify that all of the cells have water in them (if it has a cap that can be removed for inspection). If one or more cells are dry, it will lose a lot of efficiency and if not maintained at the proper level, will destroy a perfectly good battery in no time. If you do find low levels, only use distilled water to fill them back up. Link to comment Share on other sites More sharing options...
Mogatu'r Posted March 12, 2008 Report Share Posted March 12, 2008 Yes it sounds as if you have a dead cell in the battery(if it's original it's over due). Replace that and see what goes. It's not an alternator issue from your description.Bingo, I've had this happened in my S60 and 850R. My mechanic advised me on getting another battery, we put that Green labeled one, after that 2 years and the batteries were still going strong.

atefitty Posted March 16, 2008 Report Share Posted March 16, 2008 Guys-Ok, here's a quick summary of what I've got going on in my '01 S60 T5:-10 days ago, I have a dead battery.-Take the battery to get charged and tested...they say its good.-Drive for 6 days, maybe 50 miles at most, and the battery goes dead again. I know, I should have looked into it sooner, but got busy!-Take the battery to get charged and tested...they say it is great. This was this past Sunday.-Last night (Monday) I drive the car to Autozone for them to check the charging system (battery and alternator). Battery checks out fine and they say the alternator is also good since they showed it charging the battery.-This morning (Tuesday) I hear a very brief clicking sound like when I tried to start my car and the battery was dead, but after a second, it does turn over and starts. This is strange because the battery was perfect just 12 hours before hand and it had previously taken 6 days for my car to drain the battery...why the sudden jump?I'm running out of things to test! Any suggestions? According to the auto parts store's tests, the battery is good and the alternator is charging. My current working theory is that a computer isn't shutting down thereby creating a draw on the battery OR the alternator really is bad and the test results I saw last night were just on the voltage side (good voltage, but poor amps). Any input you have would be greatly appreciated.Thanks,DaveCheck your door catches...Your courtesy lights should turn off when you shut the door..Also glovebox light may be staying on..check it.
