What are the correct maintenance methods for lithium batteries?

The correct maintenance method of lithium battery 1. Charge timely 1. Lithium battery is generally in a charged half-charged state when leaving the factory. When riding for the first time, it is best to fully charge the battery. On the one hand, self-discharge will reduce the charge of the lithium battery, and it can also activate the active material in it. 2. Do not exhaust the lithium battery every time you ride. Long-term over-discharge will reduce the battery life by 3 times. When the battery is too low when the electric bike is riding, stop riding decisively. 2. Charging time 1. Lithium battery is effective at any time. It does not matter if there is 50% power before charging. This is because it is different from Ni-MH battery, which has memory effect but lithium battery does not. But it should be noted that lithium batteries cannot be over-discharged, as over-discharge will cause irreversible capacity loss. When the machine warns that the battery is low, it will start charging immediately. 2. Don't overcharge. When the charging completion indicator light is on, stop charging. If the battery is not used for a long time, the battery should be taken out of the instrument and stored in a dry and cool place, and charged once within 60 to 90 days to avoid excessive storage time, and the self-discharge of the lithium battery will cause low power and irreversible capacity loss. , Because the best storage state of lithium batteries is half-electric storage. 3. Charging to make up for self-discharge. If the lithium battery is not used for a long time, the battery should be removed from the instrument and stored in a dry and cool place, and charged once within 60 to 90 days to avoid excessive storage time and excessive battery power due to self-discharge Low, causing irreversible capacity loss, because the best storage state of lithium batteries is half-electric storage (that is, between 40% and 60% of the nominal capacity of the battery). We know that the highest voltage of lithium batteries is 4.2V. Therefore, the storage voltage is preferably between 3.8V and 3.9V, and the capacity at this time is basically half. 4. Use the original charger to use the original lithium battery charger as much as possible. The original charger has strong supporting performance and moderate charging rate. There are some fast charging piles. It is recommended not to use too much. Use it once or twice during the year. Excusable. Excessive current charging will also cause greater damage to the internal structure of the battery. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
