MiFa Battery Refurbishment – bring your e-bike back to full power
MiFa electric bikes are known for their German reliability, practical design, and comfort. Their batteries provide solid range and performance, but over time, like all lithium-ion packs, they begin to lose capacity. Reduced range, longer charging times, or sudden power drops are signs that it’s time for a MiFa battery refurbishment. This process restores your battery’s original performance without the high cost of purchasing a new one.
Why MiFa batteries lose performance
Every battery has a limited number of charge and discharge cycles. Intensive daily use, improper storage, or exposure to extreme temperatures can speed up cell degradation. MiFa refurbishment involves replacing worn-out cells with new branded ones from Samsung, Panasonic, or Sanyo and testing all electronic protection systems. After refurbishment, the battery regains its full capacity and operates safely and efficiently.
The MiFa battery refurbishment process
Each MiFa battery in our workshop goes through a precise and controlled process:
- Diagnostics: voltage checks, BMS analysis, and performance testing under load.
- Disassembly: careful opening of the casing, removal of old cells, and inspection of internal circuits.
- Cell replacement: installation of new premium cells from Samsung, Panasonic, or Sanyo.
- Safety checks: testing sensors, resistors, and protective components.
- Final testing: complete charge and discharge cycles to verify performance.
Once the process is complete, the battery is resealed, labeled, and returned to the customer with a 12–24 month warranty.
Benefits of MiFa battery refurbishment
- Much cheaper than buying a new battery.
- Eco-friendly solution – reduces electronic waste.
- Use of only high-quality branded cells.
- Restored range and stable motor performance.
- Includes a 12–24 month warranty.
- Fast turnaround – most refurbishments completed within a few days.
MiFa – practical design and proven reliability
MiFa is a trusted name in the e-bike industry, combining comfort with long-lasting performance. Even as the battery ages, MiFa battery refurbishment gives your e-bike a second life, extending its usability and keeping it ready for many more kilometers of riding.
Why choose us?
With over 14 years of experience and thousands of successful projects, we specialize in battery refurbishment. We use only new branded cells, advanced diagnostic tools, and provide a full written warranty. Each refurbished battery is thoroughly tested before being returned to ensure safety and top performance.
A second life for your MiFa e-bike
