Sparta e-bike battery regeneration – extend the life of your ride

Regeneration Sparta is a professional service that restores the capacity and performance of your e-bike battery. Over time, every battery loses power – ranges get shorter, voltage drops under load, and charging becomes more frequent. By replacing worn-out cells with brand-name components such as Samsung, Sanyo or Panasonic, your Sparta battery regains almost factory-level performance. It is a cheaper, faster and more eco-friendly alternative to buying a new pack.

Why choose regeneration?

A new Sparta battery is a significant expense, often running into hundreds of euros. Regeneration provides a cost-effective way to restore function while protecting the environment. We reuse the original housing and BMS electronics, but replace the entire cell block. This ensures perfect compatibility with your bike while reducing electronic waste and keeping your costs under control.

How does the process work?

The process begins with diagnostics: measuring capacity, testing internal resistance and checking the BMS. The housing is opened, worn cells are removed, and the electronics are carefully inspected. If needed, resistors, thermistors or safety components are repaired or replaced. New branded cells are then installed and joined using professional spot welders to guarantee durability and consistent current flow.

Testing and quality assurance

Once assembled, the battery undergoes extensive testing. We run full charge and discharge cycles, measure effective capacity, test performance under load and calibrate the BMS. This ensures predictable range, stable output and reliable operation. On request, we also check your old charger free of charge to rule out compatibility issues.
