Newbie

2006 M-Benz SL 500
I would like to ask for some advice, please?
I have a Red Battery Icon & Visit Work Shop message.
The engine compartment battery was tested at advanced auto parts & it was good.
I replaced the trunk battery, but still get the same battery warning once in awhile.
The engine compartment battery's negative cable was disconnected, voltage reading was 13.04 V
The trunk battery voltage reading was 12.99 V ,
with front/engine battery's disconnected.

Best practice is MB specific tools like Xentry or a Foxwell with MB capabilities.
Good luck and keep us posted.




The cigarettes lighter voltage reading was 14.3-14.4 with the engine running .
I will take pictures of voltage reading at both batteries & at the cigarettes lighter soon .
