i still have my battery issues...i havnt been able to get it taken care of. my car has been parked for 4 days with a dead battery. before i jumped it and it started up after 2 min the cables were attached...

now the cables from my van have been attached for 5 minutes and im not getting anything...not even that sound when you put ur key in ignition...should i just keep cables attached for 30 min?? how bad is this? my battery is absolutely dead to the world...i couldnt even open my trunk with by pushing the button on my key lol...

just didnt know if keeping the cables on the car for an extended period of time will hurt the car? or would that even rectify the problem if my battery is indedd dead? will it slowly charge and charge?

The battery could be sulfated. If it is sulfated it will not pass current. You can leave the cables on all day and it will not accept a charge nor start the car. If if the battery is broken (i.e. sulfated), it is time for a new one. Call the tow truck. Make sure it's a flat bed.

actually i just got it started...cables were on for about 10 min...im driving to my mechanic now to leave car sit for the weekend...he will check it out on monday...i told him just to replace the battery if it is the battery...if its the starter or alternator then call me back as i will have it fixed under warranty...

Your battery is toast. My old battery was the same way right before it just stopped holding a charge and I had to get a new one.

any recommendations as to what battery to get? i asked autozone what their books suggest for an 06 330xi and they pulled a battery that ran about 165 bucks....im guessing that still cheaper then a OEM one from dealership?!? would a replacement battery from autozone be a bad idea?? is it plug and play or do i need to program/register something to do so??

also im letting my car run for a little bit...if my battery is toast would it be safe to assume i can jump it anytime i need it over the weekend will it eventually drain so bad that even a jump wont work??? should i drive to mechanic right this moment or try to jump it again monday morning??!

You should register the battery to protect both the new battery and your car's electrical system. And have your mechanic check the IBS unit as well as the alternator as it would be nice to know why the battery failed.

You need to have the new battery registered to the car, only a BMW dealer or an independent shop with a GT1 tool can do this.

So did you leave the lights on? Why did it drain? If you didn't leave any electrical stuff on then it's good news the battery worked.
