I replaced the batteryon my ML this week (W164). It's my own fault - I SORN'd it in March as I wasn't going to be using it again for a while, and neglected it to the point of the battery being stone dead. I pulled it out to charge it, but to no avail. New one fitted now, and all fine, but whilst in the compartment (under drivers seat), I noticed a small additional battery. What does it do?? No SBC on this model. Would never start the car - about 4 inch cube.
