There is no clear distinction between \"fast charge\" and \"slow charge\" of the charger, which is defined according to the charging current.
< br >
1, in general, assuming the capacity of the battery is 1C, then 0.1-0.2C rechargeable battery is called slow charge.
< br >
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.
< br >
3. Take the 1800mAh nickel-metal hydride battery as an example, the charging current between 180mA and 360mA is slow charging
< br >
4, for the 700mAh battery, the charging current in this range is fast charging.
First, the current is different fast charge: fast charge is the use of 30%C current to charge the battery.
< br >
3, 2, slow charge: Slow charge is the use of 10%C current to charge the battery.
< br >
4, two, charging time is different fast charging: fast charging time is the same appliance, fast charging a charge is shorter than slow charging a charge, fast charging higher charging efficiency.
< br >
5, 2, slow charge: slow charge charging time is the same appliance, slow charge a charge time is longer than fast charge a charge, slow charge charging efficiency is lower
