High-voltage battery diagnostics measure the health of an eSprinter's traction pack and pin down why a last-mile fleet van has lost range or power. This is high-voltage work, so our Yorba Linda technicians follow factory de-energizing and safety steps before touching the pack. We read the battery management system with factory tools, test cells and modules, and locate faults without guessing.


## What this includes
- Factory-procedure de-energizing before any high-voltage work starts
- Battery management system readout of cell voltages and temperatures
- State-of-health and capacity testing to explain lost range
- Isolation and insulation resistance testing for HV faults
- Module and cell-group fault location inside the pack
- High-voltage connector, fuse, and contactor inspection

## Who it is for
- Your eSprinter has lost noticeable range on its daily routes
- A high-voltage or battery warning is showing
- Charging has slowed or the van is limiting power
- You want the traction battery checked before adding a used van to the fleet

## Pricing
HV diagnostics run on the 285 dollar factory bench at a one hour minimum, credited toward the authorized repair. The wider figure is a ballpark, put in writing after inspection.

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

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

### Can you check pack health before I buy a used eSprinter?
Yes. We pull the state-of-health data and test the pack so you know the true condition of the traction battery before you add a used electric van to your Inland Empire fleet.
