Battery and alternator service in Huntington Beach keeps your Mercedes Sprinter starting every morning and charging under load. Our Yorba Linda shop tests the battery, alternator, and starter draw with factory tools, replaces worn parts with the correct AGM or lithium-compatible components, and codes a new battery to the vehicle so the charging strategy stays accurate.


## What this includes
- Charging system test of battery, alternator, and starter draw
- AGM, lithium, or flooded battery replacement to Mercedes spec
- Alternator, voltage regulator, and belt tensioner replacement
- Battery registration and coding so the charge strategy matches the new battery
- Auxiliary and dual-battery wiring inspection for camper builds
- Corroded terminal, ground strap, and cable repair
- Parasitic draw testing to find what is killing the battery overnight

## Who it is for
- Your Sprinter cranks slow, clicks, or needs a jump to start
- A dash battery or charging warning light is on
- You added a camper power system and want the starting battery isolated correctly
- The van sits for weeks and the battery keeps going flat

## Pricing
Electrical labor is $260 per hour and battery coding uses the $285 factory bench. Ballpark range, quoted in writing after inspection.

## FAQ
### Do I need to code a new battery on a Sprinter?
Yes on most late Sprinters. The charging system tracks battery age and type, so a new battery has to be registered with factory tools or the alternator will over or undercharge it and shorten its life.

### Can you keep my camper battery separate from the starting battery?
Yes. We inspect and correct the isolator, DC-DC charger, and grounds so the house bank draws from the alternator without ever leaving you with a starting battery too flat to crank in Huntington Beach.

### Why does my Sprinter battery keep dying when parked?
Usually a parasitic draw from a module that will not sleep, a failing battery, or an add-on wired to constant power. We measure the draw and trace it to the circuit instead of just selling another battery.
