When charging, it should not exceed the maximum charging voltage, and when discharging, it should not fall below the minimum working voltage.

　　Regardless of the time, lithium-ion batteries must maintain a minimum operating voltage above. Overdischarge or self discharge reactions at low voltages can lead to the decomposition and destruction of lithium-ion active substances, which may not necessarily be reducible.

　　Any form of overcharging of lithium-ion batteries can cause serious damage to battery performance, even explosions. Lithium ion batteries must avoid overcharging during the charging process.

　　Do not frequently discharge or charge deeply. However, after about 30 Charge cycle, the power detection chip will automatically perform a deep discharge and deep charge to accurately evaluate the state of the battery.

　　Avoid high temperatures, which can shorten lifespan in mild cases, and can cause explosions in severe cases. If possible, it can be stored in the refrigerator. If the laptop is using AC power, please remove the lithium-ion battery strip to avoid being affected by the heat generated by the computer.

　　Avoid freezing, but the freezing point of most lithium-ion battery electrolyte solutions is -40 ℃, making it difficult to freeze.

　　If not used for a long time, please store it at a charging capacity of 40% to 60%. When the battery level is too low, self discharge may cause over discharge.

　　Due to the natural aging of lithium-ion batteries when not in use, purchasing should be based on actual needs and should not be excessive.
