2003 4.4i with ABS lights on plus battery

Thanks guys, really appreciate the feedback. The battery is now on charge overnight, I shall report back tomorrow with the voltage readings. I'll be peed off if the battery is at fault given the PO said he had it checked by 3 different mecahnics... he never mentioned having the alternator checked so that will be the next thing to check after the battery.

It's also possible the PO used the wrong battery. These cars use a lot of juice, and need the proper, and quite large, and costly, battery. Not a place to cut corners. I do concur with trader4's comments as well. Lot's of hack mechanics/autoparts stores will stick any battery in the car with the terminals in the right place. That's simply NOT good enough for a BMW. And with the later cars, (E70 and beyond), the new battery needs to be coded to the car.
