Winter is a time when batteries are put to special tests due to low temperatures. Using your battery properly in winter can significantly extend its life and ensure stable operation of your e-bike or other device. However, many users make mistakes that can negatively affect the performance and durability of the battery.

Freeze storage

One of the most common mistakes is storing batteries outdoors at low temperatures. Lithium iron phosphate (LiFePO4) batteries can operate at low temperatures, but they should not be left in the cold unless necessary. If exposed to cold for a long time, the battery may lose capacity and the risk of damage increases. Recommendation: always store the battery in a warm room if you do not plan to use it for a long time.

Charging in the cold

Trying to charge a battery in the cold is another serious mistake. Charging at low temperatures can damage the battery cells and significantly reduce their lifespan. Lithium iron phosphate batteries, unlike some other types, are less susceptible to problems at low temperatures, but it is still recommended to warm them up to room temperature before charging. If your battery has an automatic warm-up feature, it will help avoid this problem.

Battery is completely discharged

Many users mistakenly believe that for best performance, the battery should be completely discharged before charging. This is especially dangerous in winter, as at low temperatures, a complete discharge can damage the lithium iron phosphate cells and make the battery unusable. Recommendation: try to maintain the battery charge at 20-80% and do not allow it to be completely discharged on frosty days.

Using an unsuitable charger

In winter, it is important to use the right charger for your battery. An incorrect charger may not provide the required voltage or current, which will result in reduced charging efficiency and battery damage. For lithium iron phosphate batteries, it is recommended to use only compatible chargers that take into account the specifics of such batteries and maintain optimal charging conditions at low temperatures.

Neglecting to check the battery level

In winter, the battery loses charge faster, especially at low temperatures. One of the common mistakes is ignoring the charge level check before trips. Lithium iron phosphate batteries can work even at sub-zero temperatures, but the charge level will still decrease faster than usual. Recommendation: before each trip or use of the device, check the battery charge level and recharge it in advance if necessary.

Using the battery in extremely low temperatures

Although lithium iron phosphate batteries handle cold better than, for example, lithium-ion batteries, they still have their limits. Operating in extremely cold temperatures, below -20 °C, can be dangerous for the battery, especially if it is actively discharging. This can lead to a slowdown in the chemical reactions inside the battery, resulting in a loss of capacity. Recommendation: avoid operating the battery in extreme cold and try to use the battery at temperatures close to freezing or above.

Complete lack of service

In winter, it is important to regularly check the condition of the battery, even if you rarely use it. Lack of care and regular maintenance can lead to the battery failing prematurely. Lithium iron phosphate batteries require minimal care, but it is important to monitor their condition and promptly identify possible problems, such as reduced capacity or mechanical damage.

Battery overheating

Although overheating does not seem to be a big problem in winter, some users may not notice that overheating can occur when charging in a warm room after the battery has been in the cold for a long time. If you suddenly move the battery from a cold to a warm place and immediately start charging, it can cause it to overheat. Recommendation: Give the battery time to adapt to the room temperature before starting to charge.
