Regeneration Sachs – restore the full power of your e-bike battery
Sachs is a German brand with a long tradition in the cycling and automotive industry. Their e-bike drive systems are known for durability and solid engineering. The lithium-ion batteries used in Sachs systems provide reliable performance and range, but like all batteries, they lose capacity over time. Reduced range, longer charging times or sudden power drops are clear indicators of wear. Instead of buying an expensive replacement, Regeneration Sachs allows you to bring your battery back to life at a fraction of the cost.
Why Sachs batteries wear out
Every battery is designed for a limited number of charge and discharge cycles. Intensive daily use, extreme temperatures, improper storage or frequent deep discharges accelerate cell aging. In most cases, the casing and electronics remain intact while the cells inside become weak. Regeneration Sachs replaces those worn-out cells with new branded ones, restoring the original capacity, performance and safety of your e-bike battery.
The Sachs regeneration process
Each Sachs battery that arrives at our workshop follows a detailed process step by step:
- Diagnostics: measurement of voltages, BMS analysis and load tests.
- Disassembly: opening the housing, removing old cells and inspecting the protection circuits.
- Cell replacement: installation of new, high-quality cells from Samsung, Sanyo or Panasonic.
- Electronics inspection: testing of sensors, resistors and thermistors, replacing them if necessary.
- Reassembly: precise spot welding, proper insulation and sealing of the pack.
- Final testing: full charge and discharge cycles under realistic riding conditions.
Once completed, the battery is sealed, documented and returned to the customer with a 12–24 month warranty.
Benefits of Sachs regeneration
- Much lower cost than buying a new original battery.
- Eco-friendly solution – less electronic waste, more sustainability.
- Use of only premium branded cells for stable performance and longer life.
- Fast turnaround – most projects completed in just a few days.
- Reliable service with a 12–24 month warranty.
Sachs – tradition meets modern technology
Sachs has been a trusted name in cycling technology for decades. Their e-bike systems are used in many models across Europe and remain popular among riders who value quality and reliability. Thanks to Regeneration Sachs, you can continue using your trusted e-bike while restoring its original range and performance.
