FWIW, MB has been using Absorbent Glass Mat, or AGM batteries for several years now. They behave differently than traditional lead-acid batteries. Take a look at the battery chargers available nowadays. The better ones have a setting specifically for charging AGM batteries.

Charging a stone-dead battery until the vehicle can be started without assistance is always my first choice, but go ahead and jump-start it if this isn't possible. My Roadside Tech's do a few dozen of these every month with virtually no problems.
