Common E-bike Charging Mistakes and Risks

electric bike

As electric bikes become increasingly popular, the issue of charging electric bike batteries is also receiving more and more concerns. Incorrect charging ways and environments can cause safety problems such as battery damage, overheating, leakage, and can also shorten battery life, affecting the normal use of the bike. Therefore, understanding the errors and risks of charging electric bicycle batteries and taking necessary precautions is very important.

Electric bike charging mistakes and suggestions

Using e-bikes has many benefits in multiple ways, including reducing carbon emissions and improving traffic efficiency. However, charging the battery can also be a challenge. Most riders overlook several common charging errors that can damage the battery.

Using an inappropriate charger

Many riders overlook the issue of charging their electric bike batteries using any charger they have on hand. Riders should only use the manufacturer's original charger and charging cable that came with the electric bike. If the charger is lost or damaged, the owner should obtain another original charger from the company to match the specific bike and serial number.


Many people think that it’s not a big deal to let the electric bike battery continuously charge. However, this is a fundamental mistake as overcharging can affect the charging cycle and damage the battery's lifespan. In addition, it can cause the battery to overheat and damage the battery cells. Therefore, be mindful of the charging time of the battery and unplug the charger immediately after it's fully charged.

Lacking sustained charging

After a long period of storage, the electric bicycle battery may gradually lose its charge. If the battery is charged again, undercharging may occur. Undercharging not only shortens the battery life, but may also cause problems such as decreased battery capacity, unstable voltage, and even the inability to charge or use the battery normally.

Charging in an extreme condition

During the process of charging an electric bike battery, people should consider the surrounding environment, as both high and low temperatures can cause the battery to malfunction. In addition, riders should also avoid moisture, direct sunlight, or dust when charging the battery. To ensure good performance, it is recommended that people charge the battery at room temperature.


Improper storage of electric bike batteries can also cause damage to them. If you plan to go on vacation or store it in winter, make sure not to place it in hot or damp places. Additionally, it is recommended to partially charge the battery before storing it to avoid the battery being completely drained. If you plan to store the battery for a long time, make sure to charge it at least once a month.

Ignoring warning signs

If you ignore warning signs (such as indicating that your electric bike battery is damaged or making strange sounds or odors), your safety may be at risk. Therefore, if you notice any abnormal situations, it is wise to have a professional check your battery to ensure the safety of your electric bike and yourself.

Overall, proper use and maintenance of electric bike batteries, selecting the appropriate charger, charging environment and time, and regularly checking and maintaining the battery are key to ensuring the safety of electric bikes and extending battery life.

Common risks of electric bike battery

Undeniably, electric bicycles bring many benefits and high efficiency. But the battery brings risks and may cause serious damage to your electric bike if not handled properly. Check some of the common risks so that we can avoid them in the future.


Overheating is one of the most common risks associated with electric bike batteries, and there are several reasons why it can occur. Battery damage, overcharging, or exposure to high or low temperatures are just some of the factors that contribute to this situation. Overheating can be dangerous if not handled properly, as it can lead to fires or explosions. One way to prevent overheating is to ensure that the battery is charged, stored, and used according to the manufacturer's instructions.


Battery leakage of electric bicycle can cause harm to human body and may also damage the bike and other equipment. If battery leakage is found, stop using it immediately and wear protective gear such as gloves to avoid contact with electrolyte. At the same time, the e-bike battery needs to be sent to a professional after-sales service point for repair or replacement.

To avoid electric bike battery leakage, we should use and maintain the battery correctly, regularly check the battery status, avoid overcharging, keep the charging environment dry and ventilated, and avoid physical damage to the battery. This can extend the battery life and ensure our safe use.

Fire and explosion 

Recently, there have been multiple incidents of electric bike fires and explosions reported. This is one of the majors risks associated to electric bike batteries because they can damage your bike and other property. There are several potential reasons of fires or explosions, including battery overheating, overcharging and physical damage.

Battery malfunction

The battery of electric bike is not only the most prominent component, but also the most expensive one. If not handled carefully, it can fail and you will have to buy a replacement, which can be very expensive. The battery may fail for several reasons, such as wear or damage. This can lead to a decrease in performance and eventually stop working. For this reason, it is recommended to use professionally certified batteries ensure better performance.


The battery is a very crucial component of an electric bike, and the correct charging method and environment can directly affect its lifespan and safety. Incorrect charging way can lead to safety issues such as battery damage, overheating, leakage, and can also shorten the battery’s lifespan, affecting the normal use of the bike.

Therefore, when using an electric bicycle, it is essential to carefully read and follow the battery's instructions, choose the appropriate charger and charging method, maintain a dry and ventilated charging environment, and avoid charging in bad weather conditions. In addition, regular inspections of the battery's condition and timely troubleshooting can extend its lifespan, ensuring the safety and reliability of the electric bicycle.
