Two things struck me as odd:
1. The cells don't appear to be serviceable. Every other MB battery I've seen had six cells where you could top off the water....not this one.
2. There is no vent tube and the vent on the battery itself is plugged with a red cap. What's odd about this is that the PO had everything done by the dealer. Why would the dealer install the battery like this?

AGMs are sealed and not serviceable.
There are 2 vents on the battery, 1 at each end. You're supposed to break the red plug off the positive post protective cover plate and plug the hole that you are not using. The vent tube goes in the other hole. In the 210 there is an elbow fitting that plugs into the battery, and the tube goes straight down through the floor in a grommet.
