‘13 SL550
12V plug in trunk

Is this for trickle charge or just an extra power point?

Use the jump start points under the hood for charging / maintenance (as recommended by MB, in the owners manual). Have done it for 5 winters, on my SL, without any issues.

On my vehicle (2019 SL450) the 12v outlet is "switched", meaning that it is not connected to the electrical system when the vehicle is off.
