Suntour Battery Refurbishment – restoring power to your e-bike

Suntour batteries have been trusted by e-bike riders worldwide for their balance of durability and efficiency. Over time, however, even the most reliable lithium-ion batteries lose capacity. Reduced range, slower charging, or sudden drops in performance are common signs of aging. Instead of purchasing an expensive new unit, you can choose Suntour battery refurbishment – a cost-effective and eco-friendly service that brings your battery back to life.

Why choose refurbishment?

Every lithium-ion battery has a limited number of charge and discharge cycles. Harsh weather, heavy use, or poor charging habits can accelerate degradation. Suntour battery refurbishment replaces worn-out cells with premium-grade ones from Samsung, Panasonic, or Sanyo. The result is a battery that performs like new, allowing you to enjoy the same range and reliability at a fraction of the cost of a replacement.

The refurbishment process

Each battery we service undergoes a carefully structured process:

1. Diagnostics: voltage checks, BMS testing, and load analysis.
2. Disassembly: removal of worn cells and inspection of protective electronics.
3. Cell replacement: installation of brand-new Samsung, Panasonic, or Sanyo cells.
4. Safety testing: evaluation of sensors, resistors, and thermal protection circuits.
5. Final testing: full charge/discharge cycles under load to confirm performance.

Once complete, the battery is sealed, secured, and returned to you with a 12–24 month written warranty.

Benefits of Suntour refurbishment

• Far cheaper than buying a new battery.
• Environmentally responsible – fewer discarded batteries.
