2004 X3 Electrical HELP!!

Last night my x3 had trouble starting. The problem seemed to be that the battery was low. After trying 3-4 times to start, but failing because the starter just couldn't crank it fast enough. I took the keys out for a few minutes and waited. It started on the first attempt but with much hesitation. The next morning I got to work trying to sort this mess out. The first thing I noticed is that the indicator on the battery itself said the battery was drained (Black=No Charge, Yellow=Replace, Green=Good). I tried charging the battery at 12v(6A) for several hours but the indicator did not change. The car started, still with some hesitation, but much better than first thing in the morning or the night before.

Anybody else experience their batteries suddenly dying like this, or am I dealing with a power drain?

That eye is not a completely reliable method of determining the state of health of the battery.

It only indicates what's going on across one pair of plates, so you could have 5 other cells that are in good shape.

Conversely, you could have a green eye, and at least one of the other 5 cells dead.

If your battery has been fully discharged in the past, several times, for whatever reason, some permanent degradation is unavoidable.

(It is preferable to charge at a much lower rate than 6a., if you have the luxury of time.)

You probably now have 5 good cells and 1 poor one - could last another year or two with a bit of luck.

A parasitic drain would likely have shown up when the car was new, unless any suspect items have been added lately.

Some people get at least 10 years out of their original BMW battery, others less than 5.
I'll be happy to reach year 7.

If is the original battery, most probably is on its final days. Five years of service is ok for any battery.

Not to mention if it is an early 2004, it is approaching 6 years!

Even without the freezing winter coming up, not that you would notice in SoCal, it probably is time to retire that old soldier and get a new battery. You may wish to take a trip to coldier climes in a few months (Bear, Mammoth etc.) and you wouldn't want to get stuck up there with a dead battery when you don't have to.

I guess the age of the battery hadn't really occurred to me, strange that it died so suddenly... can't get it to charge much at all... but alas I've already ordered another, kinda steep at $144 online price, $240 not including labor at your local BMW Stealer.

Crevier BMW's online website, it uses the trade motion database, so its identical to the getbmwparts.com website.
