Tianneng Battery Regeneration – restore full power to your e-bike

Tianneng is one of the largest battery manufacturers in Asia, widely used in electric bikes, scooters and light EVs. Their packs are reliable, but like all lithium-ion batteries, they eventually lose capacity. Shorter range, slower charging or sudden cut-offs are signs of aging cells. Instead of buying an expensive replacement, Tianneng battery regeneration allows you to rebuild the pack with brand-new cells and regain the performance you need.

Why Tianneng batteries degrade

Every battery has a limited number of charge and discharge cycles. Heavy use, storage in poor conditions, deep discharges or exposure to heat and cold accelerate wear. Over time, the pack delivers less energy and the electronics may cut power unexpectedly. Tianneng regeneration fixes the core issue by replacing worn cells with fresh ones and testing the BMS to ensure safe operation.

How the regeneration process works

Each Tianneng pack that arrives in our workshop follows a proven procedure:

1. Diagnostics: capacity check, internal resistance measurement, BMS analysis.
2. Disassembly: safe opening of the case, removal of used cells, cleaning of internal parts.
3. Cell replacement: installation of new branded cells (Samsung, Panasonic, Sanyo).
4. Electronics check: inspection of sensors, fuses, resistors and protection circuits.
5. Final tests: full charge/discharge cycles under load to verify stable operation.
6. Sealing: closing and securing the housing with warranty documentation.

Benefits of Tianneng battery regeneration

• Much cheaper than buying a new battery.
• Eco-friendly – reuses the housing and reduces e-waste.
• We use only premium branded cells for long service life.
• Stable range, reliable power output and accurate charging indicator.
• 12–24 month warranty on the regenerated pack.
• Fast turnaround – most jobs completed within a few business days.
