As temperatures drop and winter sets in across the EU, the weather becomes colder and more humid, especially in December. Low temperatures, snowfall, and freezing conditions often prevent riders from using their electric bikes, causing them to remain idle during this time. If not stored correctly, the performance and lifespan of the battery can be compromised. Therefore, proper storage and maintenance are essential. Lankeleisi’s technical team offers practical advice on how to store your electric bike correctly and protect the battery during extended periods of inactivity in cold weather.
Why Do Temperature Changes Affect Battery Performance?
Lankeleisi e-bikes use lithium batteries. When winter arrives, the electrolyte inside the battery becomes viscous, reducing the activity of the substances inside the battery. The electrochemical reaction slows down, internal resistance increases, and the battery capacity decreases drastically. When the temperature drops to 0 ℃, the capacity of the battery will only be 60% of the summer.
The lower the temperature, the lower the capacity of the battery. And winter riding, low temperature will not only affect the capacity of the battery, but also for the efficiency of the battery charging. lankeleisi suggests that you do not charge the battery after the battery is completely depleted, which may lead to the battery can not be charged properly in low temperature. We recommend that you charge the battery indoors at 20-25 °C to ensure that the battery will charge properly.
So if you are about to go without riding for an extended period of time during the winter, lankeleisi suggests that you take effective measures to protect the battery of your e-bike.
How to store an e-bike that will not be used for a long time?
Where you store your e-bike is crucial, both in winter and throughout the year. The right storage environment will prevent damage to the battery and extend the overall life of the e-bike. Our technicians suggest storing the e-bike in a dry, ventilated environment, avoiding humidity and direct sunlight, and storing the battery at a temperature of 20-25°C. This prevents the battery from going into cryoprotection, which prevents the battery from charging properly.
AVOID DIRECT SUNLIGHT: The battery and frame of the e-bike are not suitable to be exposed to sunlight for a long time. The high temperature of the sun will accelerate the aging of the battery and may even cause it to overheat, affecting its performance and safety.
AVOID HUMID ENVIRONMENT: Humid environments can easily lead to short-circuiting of the battery and damage to the electrical components, so when storing your e-bike, make sure it is placed in a dry, ventilated area.
WARM TIP: If you are in a colder area, make sure that the bike is not exposed to excessively low temperatures while stored. Although most e-bike batteries are resistant to low temperatures, extreme low temperatures may still affect the performance of the battery, and it is best to store your e-bike in a warm place (in an environment of 20°C - 25°C).
How to protect the battery when not riding the e-bike for a long time?
1. Charge the battery once a week.
Winter is the season when e-bike batteries are most likely to deteriorate, especially if you don’t ride for an extended period. If you plan to store your e-bike for around three months during the winter, you should charge it at least 12 times. Charging it once a week will help activate the battery and prevent aging or degradation due to long periods of non-charging. Simply charge the battery to 70% each time.
2. Discharge the battery regularly (also once a week)
Even if you don't use your e-bike for a long time in winter, you still need to give your e-bike a deep discharge regularly. It is recommended to do it once a week, which will activate the battery and ensure that the battery activation substances are active, which is more helpful to prolong the service life of the battery and avoid battery sulphation.
How to deeply discharge the battery without riding the e-bike? You can use the bike's kickstand, tilt the bike so that the rear wheel of the bike stays suspended, turn on the meter and use the throttle to let the rear wheel turn to consume the battery power. This is a simple and effective way to help keep the battery active. Remember not to over-discharge the battery to avoid completely draining it and making it impossible to recharge.
Keeping the battery properly leveled
Regularly charging and discharging the battery once a week and maintaining the battery level between 40% and 60% helps to avoid over-discharging and over-charging, reducing degradation due to cold temperatures. In addition, this operation ensures that the battery remains active during long-term storage, preventing the aging or deactivation of internal battery chemicals and significantly extending the life and stability of the battery.
Check the battery regularly
Regularly checking your e-bike's battery will help ensure its safety, performance and longevity. When checking, you can pay attention to the appearance of the battery, whether there is obvious damage or swelling, whether the battery discharge port is loose, whether the battery charging is normal or not, and whether the battery has leakage problems. Through regular inspection, problems can be detected in time, if your battery has the above problems, you can send the problem to our after-sales staff at the first time, lankeleisi's technicians will give you professional advice to help you solve the problem, you can avoid the inconvenience of riding and safety hazards brought about by the battery problem.
Conclusion
In the cold winter, the battery of the e-bike is easy to receive the influence of low temperature and prolonged idling, which may cause the performance of the battery to decline or age prematurely, affecting the service life of the battery. In order to effectively protect the battery and prolong its service life, it is recommended to store the battery in a dry and warm environment (preferably between 20℃-25℃), and regularly charge and discharge the battery, once a week is recommended, to keep the battery power at 40%-60%.
In addition, check the appearance and connections of the battery regularly to keep track of the battery's safety. By following these simple and effective steps, you can ensure that your Lankeleisi e-bike’s battery performs well throughout the winter and is ready for new riding adventures when the temperatures rise again.
