Battery flat

[Andyk]

Well been away for 10 days and haven't used the CSL and the battery was flat. Put it on a trickle charger and it's OK now...I suppose this is normal as I don't do many miles the battery never gets recharged fully....will know next time to put it on charge.

Was the CSL locked as it does not go into sleep mode if not locked

[Andyk]

It was locked Mark. The doors opened OK and the CD player worked but the engine would catch...just clicked when the key was turned.

New battery needed ?

New battery needed ?

Not so sure. I know a Lotus is a different kettle of fish but I always had to put them on a trickle charger if I went away for a few weeks. I only do around 6 miles a day so I would imagine the battery never gets to full capacity. All seems OK now But will get it checked out and see if a new one is needed, thanks.

Perhaps a new battery is in order then.

bmw supplied me a battery as a goodwill gesture as its not covered under warrenty. Worth a try

Spoke to an x BMW sales guy who said it was nothing to worry about as BMW's are notorious for it. He has a CSL also and he left it two weeks and had to put a trickle charger on it when he got back.

worth checking for a dead cell, mines would start after about 6 weeks then when down to about 5 days , the charger indicated a dead cell and it was only charging to 70%

Cheers Derek, still planning to get it checked out.

Just get a new Batt it will save a lot of hassel and you get a 2 year warranty
on it from BMW or 3 years if you buy 1 from Halfords :thumbs:

How much are they these days Mark...have not purchased one for years.

[rs32]

does that standard M3 battery fit the CSL? Thought I read somewhere that it is more "juicy" and fits straight in ??

BMW batt is about £80
As for the m3 batt fiting the CSL yes it does but might upset
the handeling as it is bigger :whistle:
