Hi, has anyone used a CTEK 3600 to charge the battery on a 318ci?
My battery was completely flat and probably sulphated after sitting in the garage for 2 months so I got one of these.
It has been charging? now for 4 days and the red light is still on the half battery image.
Anybody have any idea how long it takes for the light to go to green on the full battery image?
A friend mentioned to me that the alternator may be damaged. Is that possible?
Any help would be most appreciated.
