The cylinder 21700 is also a relatively common device and plays a very important role in use. It will be used in electric vehicles. And it is provided to meet the requirements of electric vehicles for longer range. The timeliness of cylinder 21700 is to not exhaust the battery every time you ride, as over discharge can cause significant damage to lithium-ion batteries. What you should know when using it is that long-term discharge can reduce the battery life by three times. At least, when there is a low battery prompt during electric vehicle cycling, it is necessary to decisively stop cycling and charge the cylinder 21700. In addition, when using it, everyone also needs to know that its timeliness in charging is that lithium-ion batteries are effective at any time of charging, even if there is still 50% charge before charging, it doesn't matter. In fact, you know what causes this. This is mainly because it is different from nickel hydrogen batteries, which have memory effects while lithium-ion batteries do not. If you still don't know anything about it, you can come here to consult customer service personnel, and I believe they will also help you answer questions.

　　Until now, except for nickel hydrogen batteries, other lithium-ion batteries with cylindrical 21700 do not have memory effects. Therefore, we need to know that it can also be charged on demand. However, it should be noted that cylindrical 21700 cannot be over discharged, as over discharge can cause irreversible capacity loss. At this point, the machine will immediately start charging when it reminds that the battery is low. In addition, when using the cylinder 21700, we also need to understand that its compensation for self discharge charging is that if the battery is not used for a long time, it should be taken out of the instrument and stored in a dry and cool place, and charged once within 60-90 days. Of course, the purpose of this is to avoid storage time being too long and the battery being too low due to self discharge. The cylindrical 21700 is designed to be charged using an original lithium-ion battery charger as much as possible. Its original charger has strong supporting performance, and it is recommended to have a moderate charging rate. There are some fast charging stations now, and it is recommended not to use them too much. It is understandable to use them once or twice a year.
