2018 Mercedes-Benz GLC-Class Coupe Battery Replacement

Battery replacement for a 2018 Mercedes-Benz GLC-Class Coupe is more than swapping a cell; it requires a methodical process to preserve vehicle integrity. At Park Place Motorcars Dallas our service begins with a full diagnostic that tests battery condition, alternator performance and parasitic drains. Replacement includes removal of the old battery, installation of the manufacturer-specified unit, and execution of any required battery registration or module resets so the vehicle’s systems recalibrate correctly.
