First of all, it depends on whether your lithium battery is a single cell or a battery. The battery should be calculated according to the actual battery voltage, and lithium batteries generally have different voltage types, rated voltage 3.7. V lithium battery can be fully charged for about 4.1~4.2V, in 20℃ environment, the best battery is charged to about 3.85V for storage, and it should be removed and used one times every 3 to 6 months and recharged; some people also charge it based on battery capacity. Yes, it is generally recommended to charge the lithium battery to 40-50% capacity and store it. It also takes some time to remove it and use it. , charge it and put it away.
If it's a good battery it can be stored at full power, just be careful not to short circuit. I personally tested ua good quality battery that can be stored for one year at full capacity without swelling and with more than 70% battery remaining;
If it is an ordinary battery, it cannot be charged to 50~80% and stored, and the self-discharge rate It is also high and needs to be recharged every three months. It's best to run it every three months;
If it's a poor quality battery, it will swell over time no matter how it's stored.
Not good. Since the charging voltage of lithium batteries is higher than the rated voltage, the voltage of a .V battery can generally reach .V when fully charged. This way the battery is 1.V when fully charged. Long-term use of 1V DC voltage to charge an 11.1V lithium battery will prevent the battery from working efficiently. And the battery life isalso affected.
