There have been numerous posts on batteries ? going dead, special BMW battery chargers, etc. What I can?t find is specific information on the new LCI e60s in terms of using an external battery charger to top off the battery.
I know there is a terminal in the engine compartment to allow one to hook up jumper cables to jump another car or get a jump start, but would this be the place to attach a trickle charger periodically to bring the battery up to full charge? Or should the charger be attached directly to the battery?
Some posts have talked about damage to the electrical mechanisms, but I can?t see how that is possible if in the same respect one can jump start another car or receive a jump start.
Any clarification would be of great help. Once again I get my 535i in late September ? hence I?m data collecting at this point in time.
Thanks - Ted

As for receiving a jump well your car's dead anyways so either way you'll need to go back to the dealer might as well drive it in instead of flat beding it in if you can.
Trickle charging thats another gray area... Some will say its fine some not. I dont know myself. You shouldnt need to trickle charge that often... at most twice a year... if you drive the car normally I wouldnt see why you need it more than that. So if you want to do it right I would attach it directly to the battery since its not very often you need to trickle charge.

Hey Ted!
Yes, you can hook up a BMW (or any other reputable non-BMW brand charger) battery charger unit directly under the hood of your car. I own a Dinan-Tuned E60 545. My owner's manual actually states that ANY battery charging in the BMW should be done ONLY under the hood and in the engine compartment - not on the actual battery unit in the trunk. That's where I have my unit hooked up and it works out just fine! Hopefully, on the 535, it works the same way. Under the hood, you'll should see that positive terminal clearly identified (under that little door) for your + hookup and that small deadbolt near the shock absorber area for your ground/negative wire lead hookup. Hope this helps, Ted! GOLD PANDA
