My battery went flat today when pissing about with the stereo without the engine running. I have only used the car 3 times in the past 2 months mind...!

Fine now after a charge

Left mine 2 weeks over Chrsitmas and went flat again....not concerned as asked my BMW dealer mate who said it happens to his CSL and when he worked for BMW it was always happening to their cars....notorious with some BMW's apparently. Once charged it's fine just then any more than 2 weeks without use it deosn't like.

Anyone got any good links/websites where I can get my mits on a decent battery conditioner/trickle charger?

The one I have was a bit of a stop gap a mate bought after I left my 1st M3 without one. 6 years ago! Want one with a gauge and all, and was there not a mention of one that can identify dead cells? Clever stuff, do tell more!

Baz Try halfords or maxcess they are about £9.99

I have 1 and they work well but the bmw battery should last for a month
if the car is not used.
Remember to lock the CSL or it will stay in standbuy mode and the battery
will go flat.
If the CSL is locked it shuts the car down all but the clock and the alarm

Is that what that noise is then when the car is unlocked, everthing "waking up"? My mates normal M3 doesn't do it though

That noise you hear is apparently the SMG pump priming. Your friends must be a manual is it?
