Hercules Battery Refurbishment – restore full power to your e-bike

Hercules electric bikes have earned a strong reputation for their reliability, comfort, and German engineering. Their batteries provide consistent range and solid performance, but like all lithium-ion packs, they lose capacity over time. If your bike covers fewer kilometers, takes longer to charge, or experiences power drops, it’s time to consider a Hercules battery refurbishment. This professional service restores your battery’s performance at a fraction of the cost of a new one.

Why Hercules batteries lose capacity

Every lithium-ion battery has a limited number of charge and discharge cycles. Daily use, exposure to extreme temperatures, or improper storage accelerates aging. Hercules refurbishment involves replacing worn-out cells with new branded ones from Samsung, Panasonic, or Sanyo, followed by a full inspection of the battery management system (BMS). This ensures your battery regains its original capacity and operates safely for years to come.

The Hercules battery refurbishment process

Each Hercules battery in our workshop goes through a detailed multi-step restoration process:

1. Diagnostics: testing voltage levels, evaluating BMS functions, and performing load analysis.
2. Disassembly: opening the case, inspecting electronics, and removing degraded cells.
3. Cell replacement: installing new, high-quality Samsung, Panasonic, or Sanyo cells.
4. Safety testing: verifying sensors, resistors, and protection circuits.
5. Final testing: complete charge and discharge cycles under controlled conditions.

After completion, the battery is resealed, labeled, and returned to the customer with a 12–24 month warranty.
