Battery Issues

[stranton]

Hi all

first post

i'm on here for my mother who has a 2002 540i, now don't get me wrong i drive an Astra and can pull that engine apart all day but this is not as Astra lol. Her car battery is dis-charging and when i tried to turn it over the starter was just ticking, battery was reading 11.2 v so low, jumped the car and it started fine, alternator was showing 13.6-8 v, my Astra shows 14.6 and my dad's Supra 14.7, am I correct in assuming that this is a little low?

is there another fault that this car suffer from?

Any help would be appreciated

Cheers all Stranton

The 540 has ALOT of leccys on it which can drain the battery, plus if the battery is not in the best of condition then this will throw the alternator readings down.

New battery and your faithfull E39 will return
