How to store lithium-ion batteries?

Storing lithium batteries does not necessarily mean they will go bad, but it is recommended to discharge the battery to about 50% when not in use for a long time.

1. Why should lithium batteries be stored correctly?

During the use and storage of lithium batteries, improper operation may cause problems such as over-high battery temperature, low battery level, overcharging or over-discharging, which will seriously affect the life and safety of the battery. Therefore, it is very necessary to store lithium batteries correctly, which can effectively avoid these problems and extend the service life of the battery.

2. How to store lithium batteries correctly?

1. Temperature control: The ideal storage temperature of lithium-ion batteries is 20℃, but in actual scenarios, we may not be able to fully control the temperature. Generally speaking, lithium batteries can be used and stored normally within the temperature range of 0℃~60℃. However, do not place the battery in direct sunlight or in a high temperature environment. If the storage environment temperature is too high or too low, the capacity and life of the battery will be affected.

2. Power control: When lithium batteries are not used for a long time, it is best to place them at a power level of about 50%. If the battery power is too high or too low, it will affect the safety and life of the battery. If the battery power is too low, it may cause the battery to fail to charge, while if the power is too high, it is easy to overcharge, which will increase the risk of battery self-ignition at high temperatures.

3. Avoid heavy pressure: Avoid being squeezed and collided by heavy objects or other hard objects, which is likely to damage the structure and cells of the battery, causing the battery to fail prematurely, and also increase the risk of fire accidents.

3. What are the precautions for storing lithium batteries with full power?

Generally speaking, storing lithium batteries with full power will not cause damage to the battery or make the battery fail, but when not in use for a long time, it is recommended to discharge the power to about 50%. If it is only temporary storage, there is no need to consider too many problems. But if it is long-term storage, you need to pay attention to the battery power and storage environment, and try to avoid long-term storage in high temperature, low temperature or humid environment.

Proper storage of lithium batteries can effectively extend the service life of lithium batteries and avoid safety hazards such as overheating, overcooling, overcharging or over-discharging. Storing at full power does not necessarily cause battery failure, but if it is not used for a long time, it is recommended to discharge the power to about 50%. Proper storage and operation of lithium batteries can help us better use these batteries, avoid premature battery failure, and also reduce the risk of accidents.
