Batteries retire long before they are finished.

  • Retired, not finished

    Retired EV pack, seen from above

    Most EV batteries leave the road with plenty of capacity left.

  • Reuse without proof

    Lid off: 96 cells, none tested one by one. Dashed = not tested.

    Pack health74 %Example

    Pack-level reuse tests the pack, not each cell inside it.

  • New costs more

    Buying new cells means higher prices and a bigger footprint.

How it works

Follow one cell from a retired EV pack to a certified battery.

  1. We source retired EV batteries through recycler and OEM partners.

  2. Packs are taken apart down to individual cells.

  3. Each cell is measured for capacity, resistance and health.

  4. Passing cells get a digital record you can look up any time.

  5. Only top-grade cells go into our certified systems. The rest are recycled.

Know what's inside, down to the cell.

Every cell carries a passport with its test results, age and origin. Scan the pack, see the data. Share it with your customers, auditors or insurers.
