18650 battery 3.7 v Advanatage

Safety designs of PTC(Positive temperature Coefficient) and CID(current interrupt device) are integrated in the cell’s internal structure, which can avoid explosions and fires. When the 18650 2200mah 3.7 v cell is short-circuited, the vent mechanism can vent out the gases and overheating immediately due to a high increase in pressure.

Cell match is the vital symbol of reliability and stability, which is a key factor in multiple cell assemblies. 18650 battery 3.7v 2200mah can maintain voltage tolerance within 10mV, capacity tolerance within 5mAh and internal resistance within 1mΩ.

18650 2200mah 3.7v can maintain ultra-long cycle life up to 1000 times with 80% capacity retention. For most applications, it can be used for a shelf life of 2 years. Furthermore, the self-discharge rate of 2200mAh 18650 battery is as low as 2% per month, ensuring the lowest capacity loss even after months of storage.

A:Single 18650 battery cell can’t reach 9900mAh.If it is a 18650 battery pack with 9900mAh, you can charge same way as 18650 2200mah 3.7v,but the charging time would be 4 times longer than 2200mAh cells.
A: Due to the internal self-discharge rate, the 18650 3.7V 2200mAh battery should be charged per 6 months.Otherwise,the battery will be over-discharged to die.
A: 2200mAh means the battery capacity.We have the high drain current version and the cells can support max 30C(66A) discharge rate.
