Usually around 3 years.
Lithium batteries should not be stored for a long time. They should be charged to 50% to 80% capacity and stored in a cool, dry environment. They can typically be stored for 10 months. at 1 year. However, if you want to ensure battery life, you should charge the battery every 3 months to avoid being stored for too long. The battery will be too weak due to self-discharge, resulting in the lithium battery remaining. a state of deep sleep, leading to irreversible loss of capacity and the inability to recharge the consequences of use.
Precautions for charging lithium batteries
When lithium batteries for electric vehicles become more and more common in the market, many people do not understand the correct charging method Li batteriesthium for electric vehicles. .
Lithium batteries are now the first choice for electric vehicles. Lithium batteries are lighter and larger. In terms of performance, they can also be charged and discharged normally. between -20℃ and 55℃, the service life is 3-4 times that of lead-acid batteries of electric vehicles.
1. When not used for a long time, the battery should be stored in a dry and low temperature environment, away from heat sources and out of direct sunlight.
2. The battery should be charged to approximately 40% and stored at a temperature of 10 to 30 degrees Celsius, and should be recharged approximately every six months.
3. Do not store the battery with ordinary metal objects, otherwise it will cause battery leakage, short circuit and other damage, which is not good.
