My 2013 GLK 350 had the aux. battery light come on. I just replaced the relay and checked that battery with my maintenance charger and it told me the battery was charged. The aux batt. malfunction light is still on. Any suggestions?
Want want to try the GLK X204 forum. If you have eco stop/start then that battery used during stops when engine cuts off could be bad.

Battery is battery regardless the car model.
Testing the battery is whole science but latest gauge made it quite easy.
