AGM vs flooded — which does this vehicle need?
The 2025 Mercedes-Benz Sprinter requires an Absorbent Glass Mat (AGM) battery. The complex electronics, start-stop system, and high electrical demands of modern Sprinters necessitate the stable power and deep-cycling capabilities of an AGM battery. A traditional flooded battery will not provide adequate performance or longevity.
Post-installation relearn / reset procedure
After a battery disconnect, the Sprinter may require a reset procedure to restore full functionality. This typically involves:
- Steering Angle Sensor Reset: With the engine running, turn the steering wheel from lock to lock, then return to center.
- Window/Sunroof Reset: Cycle each window and the sunroof through their full range of motion, holding the switch for a few seconds at each limit.
Signs of a failing battery
- Slow engine crank
- Warning lights on the dash
- Electrical issues (dimming lights, etc.)
- "Stop Vehicle Shift to P Leave Engine Running" message
Common battery issues for this generation
The most common issue is premature failure of the main battery due to the high electrical load. The auxiliary battery can also fail, leading to issues with the start-stop system and other electronics.
