Tip: Many Mercedes-Benz models require battery registration after replacement so the onboard charging system adapts to the new battery’s profile.
Switch off ignition, wait for electronic systems to go to sleep.
Disconnect the negative terminal first, then the positive.
Install the new battery securely with correct vent routing.
Connect positive terminal first, then negative.
Perform battery registration if required.
