Battery flat

[Jaw_F430]

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

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 :thumbs:

Is that what that noise is then when the car is unlocked, everthing "waking up"? My mates normal M3 doesn't do it though :smt017

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

Indeed it is :thumbs: Learn something new everyday :-D

Me too! :-D

I use a Halfords 12v battery charger/conditioner. Does the trick - £20 or so.

hi chaps ,work on a few csl,s etc and all batteries go flat quickly ,part of the problem is the distance between battery and starter motor ,long cable means voltage drop etc so it dosent take much for the car not to crank over .
when buying a trickle charger its best to go for one that has a built in cut off incase anything goes wrong ,and leave car unlocked so the charger tops battery up and then lets it go down a bit before charging again ,it makes for longer battery life so im told and avoids dead cells

Left mine for 25 days, and started first time.
But then again, I have a standard battery.

I left the csl at the in laws for 2 weeks, in the snow outside and it started fine. Put it in the garage, for 3 weeks and it didn't start. went out in it on Saturday and it didn't start - had to jump start it and prayed it started again when I stopped to get some petrol. I think though I will get a new battery as the one in there hasn't been changed since new!
