Very handy site
Thanks for the helpful tips , yes I do a lot of short journeys , I will charge over night then check 4 hours after I’ve charged to see if I get a drop , I had a leak at the battery it’s not a particularly great brand I don’t think , not a name ive heard !

My time and date seem to reset most nights , my main battery seems fine , is there a battery just for time date ? I have a X6 35d 2009
Thanks in advance
