Main battery issue after replacement
So I bought a brand new Mercedes battery with the same part Nr. and replaced it by myself. The car was out of power about 1/2 hour.
When I plugged it, following red message showed: Battery not charged. While driving it change to white “Charge battery.”
Does the battery need to be activated by dealer workshop?
Note: the new battery is fully charged. Tried to connect obd2 but no error reported. The engine starts as new even in cold mornings.
