Giant e-bike battery regeneration – restore endurance and reliability

Giant Regeneration is a professional service created for riders who want to extend the life of their Giant e-bike batteries without investing in expensive replacements. Even though Giant batteries are designed for durability and long distances, regular use, steep climbs, and frequent charging cycles inevitably reduce their capacity. As a result, the range decreases, the motor loses efficiency, and your e-bike no longer feels as powerful as before. Regeneration is the solution – a process that gives your battery a second life and restores the performance you expect from a Giant bike.

Why regenerate your Giant battery?

Purchasing a brand-new Giant battery can be costly, sometimes harder to source for older models. Giant Regeneration provides an affordable and sustainable option. Instead of replacing the entire unit, we remove the worn-out cells and install brand-new ones from trusted manufacturers like Samsung, Sanyo, and Panasonic. The original housing and Battery Management System (BMS) remain intact, ensuring compatibility and safety while reducing unnecessary electronic waste.

Common issues solved by regeneration

Riders often notice clear signs that their Giant battery needs servicing:

• Sudden drops in range despite full charging.
• Frequent overheating during longer or uphill rides.
• Unexpected shut-offs of the assistance system.
• Charging problems or rapid discharge after just a few kilometers.

By replacing the cell pack, these issues are eliminated, giving your battery consistent and reliable output again.

The regeneration process

Every Giant battery we receive undergoes a detailed diagnostic check. We disassemble the casing, remove old cells, and test all electronic components including the BMS, resistors, and sensors. Any damaged parts are replaced. A brand-new pack of premium lithium-ion cells is then spot-welded using professional machines for maximum precision and safety. After assembly, the battery is tested through full charge/discharge cycles, capacity measurement, load performance, and thermal checks. Only after passing these tests is the battery returned to the customer.

Benefits of Giant battery regeneration

• Save significantly compared to purchasing a new Giant battery.
• Eco-friendly solution – reuse of original casing and electronics.
• Installation of premium branded cells (Samsung, Sanyo, Panasonic).
• Stable range even on long tours and demanding terrains.
• 12–24 months warranty included.
• Fast turnaround – most orders are completed within a few working days.
