How long does it take to charge a lithium battery for the first time?

The first charging time of the detailed lithium battery can be determined according to the actual battery capacity. The first time the lithium battery is charged, it does not have to be charged for 12 hours. The current lithium battery is different from the battery of the old mobile phone in the past, and it can be overflowed in about 2 to 4 hours. Lithium batteries count as the number of full charges. The first charging time is within 5-6 hours, just let the battery overflow. At present, the charging speed of lithium batteries that are generally charged is not fixed. It depends on the capacity of the battery, the current of the charger, and the conversion efficiency of charging. If your battery has a large capacity, your charging The current of the charger is small, and the maximum input current is not reached, and the charging speed will be slower. The capacity of the battery is expressed in mAh (milliampere hour), and the discharge rate of how many milliamperes can be discharged means that it can be discharged for one hour. A 1500mAh battery can be discharged at a discharge rate of 1500 mA for one hour, and at a discharge rate of 500 mA (500 mA), it takes 3 hours. Generally, the charging current of a lithium battery is set between 0.2C and 1C. The larger the current, the faster the charging and the greater the heat generated by the battery. Moreover, charging with an excessive current will result in insufficient capacity because the electrochemical reaction inside the battery takes time. In the use of lithium batteries, it should be noted that after the battery is left for a period of time, it enters the dormant state. At this time, the capacity is lower than the normal value, and the use time is also shortened. But the lithium battery is easy to activate, as long as 35 normal charge and discharge cycles can activate the battery and restore normal capacity.
