Looks like the battery on my W210 needs replacing - it's 10 years old and won't take a charge. I might also get a new one for the W126 while I'm at it.
Does anyone know a good mobile service that will come out to my home and replace them? The cars don;t get used much so is there a particular battery that may be better for them or should I just look after each of them with a trickle charger?
