High-Voltage Battery
Repair & Restoration
Battery repair at cell level
We repair batteries at module level, which usually costs less than a new unit. In many cases only a few modules have failed. We identify those parts and fix them, saving you from an expensive total replacement.
How we repair
a battery
Measure every cell, replace only what fails, then balance and test.
- 01
Cell-level diagnosis
Our diagnostic process extends well beyond basic error code reading. We conduct a detailed analysis of the entire battery pack, measuring the voltage, internal resistance, and capacity of each individual module and cell. This data-driven approach allows us to pinpoint the exact source of the fault with greater precision.
- 02
Repair and module replacement
Once the faulty components are identified, our technicians, trained in electric vehicle safety and diagnostics, repair the battery. Instead of discarding the entire battery, we replace only the failed modules or cells with high-quality, tested components.
- 03
Balancing and testing
After the repair we balance the cells so the modules work together. Then we run high-load tests and monitor the temperature.
Warranty
Up to 4 years
or 100,000 km, whichever comes first
Battery repairs come with a warranty of up to 4 years or 100,000 km, whichever comes first. The terms depend on the battery and the car model. The warranty comes in addition to your rights under Norwegian consumer law.
