Battery Maintenance Charger W221 Question
Hello!
I have a 2007 MB S550. I am going on a trip for a month and a half and I have a "smart" battery maintenance charger. Where should I hook up the charger? I have been reading conflicting information on how to. Especially with the two batteries located in the car. I am sure there must be a simple solution but I am a bit worried to disconnect them. I'm guessing the best is to charge the trunk battery from the hood?
Any info would be great appreciated!
