When charging, it should not be higher than the charging voltage, and when discharging, it should not be lower than 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 cause the decomposition and destruction of lithium-ion active substances, which may not necessarily be reducible.

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

　　Do not frequently discharge or charge deeply. However, after approximately 30 charging cycles, the battery detection chip will automatically perform deep discharge and deep charging to evaluate the battery's condition.

　　Avoid high temperatures. Mild cases can shorten lifespan, while severe cases can cause explosions. 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.
