There is no clear distinction between \"fast charge\" and \"slow charge\" of the charger, which is defined according to the charging current.
1, in general, assuming the capacity of the battery is 1C, then 0.1-0.2C rechargeable battery is called slow charge.
2, greater than 0.2C is called fast charging, greater than 0.8C is called super fast charging, less than 0.05C is trickle charging.
3. Take the 1800mAh nickel-metal hydride battery as an example, the charging current between 180mA and 360mA is slow charging
4, for the 700mAh battery, the charging current in this range is fast charging.
