On vehicle settings there’s an energy flow section. I clicked on that before charging and it showed 100%. From there I changed the battery setting to 10A and started charging at 1608. The charger stopped charging at 1700 and the plug was disconnected. Battery was at 100% prior to charging. I’ve complained to Mercedes Loughton and Stratford about this in the past and no one was interested. They told me to fiddle about with the buttons. Didn’t know what they meant, which was why I joined this forum. Do you have to charge your car up two/three times a day? I normally do 25 miles per day.
