Renovation of Electric Bicycle Batteries
We offer the refurbishment of battery packs that do not work or drive far too few kilometres.It's no secret that an electric bike quickly becomes your faithful companion in everyday life. Therefore, it is of course also something that affects everyday life when the e-bike's battery is about to wear out or is completely defective. The battery must of course be refurbished, and you can safely have that done here at Shengli Energy in Dongguan.
Got a battery pack that isn't working as it should? Then we can help with the repair of the battery for your electric bicycle. We run a test on the battery pack to analyze the battery's faults and deficiencies and clarify the problem. We will then estimate a price for you to repair the battery pack. There can be several reasons why a battery pack fails - from problems with the BMS (Battery Management System) to the battery cells.
It is often advantageous to have new battery cells installed in your old battery instead of buying a brand new one. It is a great advantage for you to have a battery renovation done on your electric bike, as you can save a lot of money just choosing a repair. In addition, you can often upgrade your battery with battery cells that are even better and stronger than your current battery. You therefore get even better traction and a longer range on your electric bike, so you can once again go on a long ride on your bike and enjoy the fast speed.
In addition to refurbishing electric bike batteries, we at Shengli Energy also refurbish batteries for cabin scooters.
Do you also want your electric bike or cabin scooter back in full bloom? Then give your battery new life with a renovation at Batteri-Energi.

Read and understand all safety warnings. Failure to follow the below warnings could result in death or serious injury. Save all safety warnings and instructions for future reference.
- Do not puncture or crush the battery pack. Do not impact the battery pack or modify it in any way. Do not use the battery pack if it shows visible damage. Danger of fire or explosion which can cause death or serious injury.
- Protect the battery pack against heat (e.g., temperature >60°C), fire and immersing into water. Danger of explosion.
- Remove the battery from the ebike before performing the following works: inspection, repair, assembly, maintenance on the ebike, transporting it with a car or airplane, or storing it. Unintentional activation of the ebike system poses a risk of injury.
- Do not open the battery. There is a risk of shortcircuiting. Opening the battery voids any and all warranty claims.
- Never touch the two battery electrodes at the same time as this could cause an electric shock.
- When the battery is not in use, keep it away from paper clips, coins, keys, nails, screws or other small metal objects that could make a connection from one terminal to another. A short circuit between the battery terminals may cause burns or a fire. Short circuit damage which occurs in this instance voids any and all warranty claims against Hailong battery of Shengli Energy.
- Avoid mechanical loads and exposure to high temperatures. These can damage the battery cells and cause the flammable contents to leak out.
- Do not place the battery near flammable materials. Ensure the battery is completely dry and placed on a fireproof surface before charging. There is a risk of fire due to the heat generated during charging.
- The ebike battery must not be left unattended while charging.
- If used incorrectly, liquid may leak from the battery. Contact with this liquid should be avoided. If contact accidentally occurs, rinse off with water. If the liquid comes into contact with your eyes, seek additional medical attention. Liquid leaking from the battery may cause irritation or scalding.
- If used incorrectly, liquid may leak from the battery. Contact with this liquid should be avoided. If contact accidentally occurs, rinse off with water. If the liquid comes into contact with your eyes, seek additional medical attention. Liquid leaking from the battery may cause irritation or scalding.
- The battery may give off fumes if it becomes damaged or is used incorrectly. Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The fumes may irritate the respiratory system.
- Only charge the battery using original battery chargers. When using chargers that are not supplied by Shengli Energy, the risk of fire cannot be excluded.
- Keep the battery away from children.
The safety of both our customers and our products is important to us. Our ebike batteries are Lithium- ion batteries which have been developed and manufactured in accordance with the latest technology. We comply with or exceed the requirements of all relevant safety standards. When charged, these Lithium ion batteries contain a high level of energy. If a fault occurs (which may not be detectable from the outside), in very rare cases and under unfavorable conditions, Lithium-ion batteries can catch fire.
The durability of an e-bike battery varies from battery to battery and from bike to bike. Just as the number of kilometers you can drive on the charges depends on driving style, charging hours and other factors, there is also a lot that can affect the durability of the battery itself.
Around 1000 full charges is not an unreasonable expectation. But it can also be quite a bit less or more, and it is therefore only a rule of thumb. In other words, it is not unusual if your battery loses power after 600 discharges and charges or lasts for 1100.
On the other hand, it is quite certain that an inspection of the battery for the electric bike and renovation provides the best possible conditions for a long time with optimal performance and lifetime for both the battery and driving pleasure.
Yes, you can repair the battery for an electric bicycle. We are used to having our bikes repaired when the gears, tires or brakes are not working as they should. This of course also applies to the modern electric bicycles, which have quickly become incredibly popular.
The batteries on the electric bike are another thing that it pays to have looked at and repaired. By replacing battery cells, refurbishing or making repairs, the performance of the bike can be optimized and the lifespan can be extended.
At Shengli Energy, we can, for example, analyze and find specific faults in battery packs, replace individual parts such as cells and charging ports or fix the entire electronics. You can also get new and more efficient battery cells. Replacing or refurbishing the electric bike battery can give the bike new speed and improve durability.
