canuckinaustria Posted May 26, 2010 Report Share Posted May 26, 2010 My battery in my 2008 Limited has died approximately 8 times in the last two months. I brought the car with me to Europe, and it was adapted in order to fit the lighting descriptions, etc. My problem is I don't know where to start with testing it to figure out where it was screwed up. Any suggestions? Please help... my wife is ready to set fire to the car, and I love it... Quote Link to comment Share on other sites More sharing options...
Depiry Posted May 26, 2010 Report Share Posted May 26, 2010 Try using a 12 volt test lamp (with the sharp probe) in series with either battery cable a light will mean a current draw,no light all clear,you can leave it on and disconnect things to make the light go out and find the problem,you can also use a multi meter set on low amps or more sensitive volts,good luck Marty Quote Link to comment Share on other sites More sharing options...
claas900 Posted May 28, 2010 Report Share Posted May 28, 2010 You could have a relay sticking. If your batt and alternator test fine it might be something to look into. Quote Link to comment Share on other sites More sharing options...

DJ Nap Posted June 10, 2010 Report Share Posted June 10, 2010 Did you find a reason why? the latest reason was that it had shorted itself out Quote Link to comment Share on other sites More sharing options...
NeckDlight Posted October 19, 2017 Report Share Posted October 19, 2017 Anyone ever find the reason why is draining. Are you saying the battery shorted itself out? Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted October 19, 2017 Report Share Posted October 19, 2017 Ive read there are a couple of reasons a battety shorts internally. One is the plates develope crystals. When they grow large enough, they can bridge from one plate to another, shorting the cell. The other (and more common) is the lead plates breakdown over time, shedding small particles of lead to build up at the bottom of the battery. When it gets deep enought, this layer of lead sulphate reaches one the bottom of the plates, shorting them out. There are several videos on YouTube showing how to dump out the water-acid solution, flush out the battery and neutralize it with baking soda, then refill with acid or vinigar. Works! (But for how long)? Quote Link to comment Share on other sites More sharing options...
macbwt Posted October 21, 2017 Report Share Posted October 21, 2017 Most of my battery drain issues were related to Wife and Kids - interior lights turned on. 1 Quote Link to comment Share on other sites More sharing options...
