7 tips for e-bike battery maintenance in winter

Nov 10,2022 | DFShop

With the onset of winter, many owners will find that their e-bike will "not run as far as before" and "charge more often". In fact, this is all because of the electric bicycle battery, which is also "frozen". Now most electric bicycles mainly use lead-acid batteries or lithium batteries as the power source. When the temperature drops, the activity of lead-acid batteries decreases, the resistance increases, the battery capacity becomes smaller, the charging effect decreases, and the storage capacity becomes worse.

In winter, if you want your electric bicycle to still work well, whether it is a lead-acid battery or a lithium battery, you should do a good job of battery maintenance. The following is the battery maintenance methods summarized by DFShop, a professional electric bicycle service provider.


1. Be diligent in charging

Winter e-bike battery is easy to use up the electricity, so if possible, charge it as you go, do not use it at a loss. Even if you are not far from the range requirements, a charge can be used for 2 to 3 days, but you are still recommended to charge every day, which is conducive to the battery in a shallow cycle state, the battery life will be extended.


2. Be fully charged

Every time you charge the battery, it should be fully charged before use. If it is not fully charged, the battery will have a kind of "memory", which will affect its range and lose its service life. Newly purchased electric bicycle first charge, the best continuous charging 12 hours, but each time after the best not to exceed 12 hours of charging time. After six months of use, it's best to go to a repair shop for battery maintenance.


3. Learn to keep warm

The best ambient temperature for battery charging is 25 degrees Celsius. In the cold winter, be sure to increase the charging voltage and extend the charging time, and take insulation and anti-freezing measures, for example, when the e-bike battery is not in use, it can be placed in a higher temperature room, and should not be placed directly on the ground. If the battery cannot be disassembled, you can park the e-bike in the house overnight.


4. Ride with more assistance

When riding, you should make use of the booster and glide as much as possible. If you are going downhill, use inertia as much as possible and slow down in advance by cutting off power. When you encounter a traffic light, enter the skid in advance to minimize braking. In addition, at the time of starting, it is best to join the riding assistance, pedal the ground with your feet to help the car start, not only to improve the start-up speed, but also to reduce the loss of battery power.


5. Pay attention to moisture prevention

When the battery enters the warm room from the cold state outside, the surface of the battery will appear frost and condensation. In order to avoid battery leakage or short circuit caused by frost and condensation, it should be wiped clean in time and dried before charging. More rain and snow in winter, do not ride into deep water, deep snow, to prevent the battery, motor moisture, but also pay attention to moisture, such as the electric bike can be moved indoors, or covered with moisture-proof cloth.


6. Develop good habits

Develop good habits, don't brake frequently, don't pull out the speed limiter, don't overload, start slowly, and don't pull the electric door hard.


7. Choose high quality battery

The battery is the core component of an electric bicycle, so you should choose a well-known manufacturer or brand when buying an electric bicycle or replacing the battery. Don't be greedy for cheap. Especially cheap ones may be refurbished batteries, inferior batteries, quality can not be guaranteed. If possible, try to choose lithium battery electric bicycle, which not only can guarantee the life and efficiency of the battery, but also can ensure the durability in critical moments.
