When charging, it shall not be higher than the maximum charging voltage, and when discharging, it shall not be lower than the minimum working voltage.
Regardless of the time, the lithium-ion battery must be kept above the minimum operating voltage. Low-voltage over-discharge or self-discharge reactions will cause the lithium ion active material to decompose and destroy, and may not necessarily be reduced.
Lithium-ion battery overcharge in any form will cause serious damage to the battery performance, and even explosion. Lithium ion batteries must avoid overcharging the battery during the charging process.
Do not often discharge deeply and deeply. However, after about 30 charging cycles, the power detection chip will automatically perform a deep discharge and deep charge to accurately assess the state of the battery.
Avoid high temperature, and shorten the life span at the lightest level. In severe cases, it may cause an explosion. If possible, store in the refrigerator. If the laptop is using alternating current, please remove the lithium-ion battery bar 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 at -40 ℃, and it is not easy to freeze.
If it will not be used for a long time, please store it with 40%～60% charge. When the power is too low, it may cause over-discharge due to self-discharge.
Since lithium-ion batteries will naturally age when not in use, they should be purchased according to actual needs, and should not be purchased too much.
