After the mobile phone lithium battery is fully charged, it will not fail even if it is turned off for a year.

When you buy a new mobile phone and turn it on after receiving it, you will find that the battery is still more than 50% charged. This is essentially fully charged before leaving the factory and will ship after testing without any problems. Inventory, transshipment, etc. can take a week or several months, and sometimes the inventory can last a year. There is no mention of a battery failure.

Although it is recommended to discharge and charge lithium batteries once a month or two months after use, if the battery is stored in a good environment for a long time, battery failure will not happen for six months. or a year.

Usually around 3 years.

Lithium batteries should nots be stored for a long period of 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 lithium batteries for electric vehicles. .

Lithium batteries are now the first chchoice 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.
