Battery Change & Programming
Modern Mercedes vehicles require more than a simple battery swap. We select the correct AGM/EFB battery for your VIN, install it safely, and register/code it with XENTRY so the charging strategy, energy management, and diagnostics remain accurate. A start/charge test verifies alternator output and voltage stability, and we scan for stored energy-related faults. You leave with a clear report and a car that starts confidently—exactly how we deliver a Good Job.
Symptoms like slow cranking, start/stop deactivation, or sporadic warning lights often trace back to aging batteries. Correct coding prevents chronic under- or over-charging that shortens battery life and stresses the alternator. If your model has an auxiliary battery, we’ll test it too, and quote replacement if it’s drifting out of spec.
- Correct battery by VIN: Capacity, technology (AGM/EFB), and layout matched to your model.
- Coding/registration: XENTRY update so the car “knows” the new battery age/state for smart charging.
- Electrical hygiene: Terminal cleaning, secure mounting, cable routing, and IBS (sensor) checks.
- System verification: Start-load and alternator tests; fault memory review for energy modules.
