My mom has a 2000 740iL that is continuously having battery problems. We've recharged her battery a few times, and have gone through a few new BMW batteries. Their batteries are NOT cheap.

She's not leaving any lights on or anything, and all the electrical seems to be fine inside.

Where do I start looking, and what for?

Any help is greatly appreciated.

Standard battery drain troubleshooting? Pull the fuses? Check for drain with a 12v light bulb?
