Yes the battery is in the boot behind the offside side trim panel.

The battery has almost certainly had it ... count on needing a new one. They suffer permanent damage once the voltage drops below a certain point.

If you have power in the garage then a maintenance charger is the answer. They are not expensive, and keep the battery fully topped up. My SL is hooked up to one every time it goes in the garage:

AccuMate Battery Chargers - the intelligent 6V, 12V & 24V maintenance chargers

thanks...i read jump starting can damage electrics and blow fuses...so will probably invest in a charger from ebay....

If you just hook up a spare battery that should be fine. But connecting to another car with the engine running can cause problems.

Definitly DON'T jump start it - I blew my roof controller doing that!!

I jump started my E200 several times from another well-charged battery. First time was by the AA assistant, then by me. (I had the car for a long time, and I am on the third battery now).

I use one of these on my 300SL and it's great. Before I bought it, my battery was always going flat, now (touch wood) I never get problems.
