Here C refers to the battery capacity (capacity of the English first letter) 0.5C=145mA then the battery should be 290mAH
The c number is the ratio of the charge and discharge current to the battery capacity
< br >
For example, a 5ah battery, 2a discharge, is 5\/2=2.5c discharge, charging is the same
The 0.5C charge and discharge and 1c charge and discharge in lithium batteries mean that they are charged and discharged according to 0.5 times or 1 times the battery capacity. Charging of lithium battery: According to the structural characteristics of lithium battery, the maximum charging termination voltage should be 4.2v, and it can not be overcharged, otherwise it will take away too much lithium ion from the positive electrode, and make the battery scrapped. Its charge and discharge requirements are high, and special constant current and constant voltage chargers can be used for charging.
