High-voltage battery diagnostics in Huntington Beach measure the health of your eSprinter's traction battery and find why range or power has dropped. This is high-voltage work, so our Yorba Linda technicians follow factory de-energizing and safety procedures before touching the pack. We read the battery management system with factory tools, test cells and modules, and pinpoint faults without guessing.


## What this includes
- Factory-procedure de-energizing before any high-voltage work begins
- Battery management system readout of cell voltages and temperatures

- Module and cell-group fault location within the pack
- High-voltage connector, fuse, and contactor inspection

## Who it is for
- Your eSprinter has lost noticeable driving range
- A high-voltage or battery warning is displayed
- Charging has slowed or the van limits power
- You want the traction battery health checked before a purchase

## FAQ
### Is it safe to diagnose an eSprinter high-voltage battery?
Yes, when done correctly. Our technicians are trained on high-voltage systems and follow Mercedes de-energizing and personal protection procedures before any work, so the pack is safely isolated before testing begins.

### Why has my eSprinter lost range?
Range loss can come from cell degradation, a weak module, thermal management issues, or a charging fault. We test the battery management data and the pack itself to identify the real cause rather than assuming the whole battery is worn.

### Can you check the battery health before I buy a used eSprinter?
Yes. We read the state-of-health data and test the pack so you know the real condition of the traction battery before you commit to a used electric Sprinter in Orange County.
