Black indicator on battery
what the black battery indicator shows is the battery is below an acceptable charge level. You can purchase a Ctek 7000 in the UK, that is what mine is !! You can use the recover battery feature on this charger and you may well get the battery back to full charge. Mine was in the black, I bought the charger, did the recover cycle , ( but left the boot open and moved stuff from around the battery just in case ???).
As you are using your car very little do as I do and do a charge on a weekly basis, then you may not have to purchase a new battery.
There are lots of comments about where to charge from ie engine bay or boot , I have a ctek wire permanently connected to the terminals around the battery and charge through this......in the boot. BMW sell these in their parts department or buy from Ctek. either way makes charging very convenient.
