The nominal capacity of a battery is 1C, and the charging current is 0.1-0.2C for slow charge, > 0.2C for fast charge, > 0.8C for ultra-fast charging, < =0.05C is trickle charging. Taking a 1400MAH nickel-metal hydride battery as an example, the charging current is between 140MA-280MA for slow charging, and the same 280MA charging current is fast charging for a 700MAH battery. It can be seen that fast charge or slow charge is a relative concept, and the capacity of the battery itself is greatly related.
Slow charge: refers to the process of replenishing the battery and other devices.
It takes a long time to charge. It takes a long time
The charging current is relatively small and takes a long time, which is slow charging
