one
Fast charge is to increase the charging current and can be filled in a short time. Slow charge is normal charging, and the charging current is normal. No harm to the battery.
two
Fast charging is relatively harmful to lithium batteries, and fast charging is not satisfied, to about 90%, because the charging current is large, which will affect its life. A slow charge can be fully charged and the battery will last longer than a fast charge.
three
Fast charge is for emergency use. In normal use, it is still good to wash slowly. Fast charging is a non-original battery charging device, which has no benefit to the battery and is not recommended. Original charger should be used.
The current charging line also has fast charge and slow charge, so the battery also has fast charge and slow charge
The difference between them is that when the battery is charged, it will be faster when charging, slow charging, he will fill the razor within 30 minutes, and fast charging, she only needs ten minutes to fill your razor, this is the difference between the two
Now there are two kinds of electric shavers, one with lithium batteries, and one with dry batteries.
Fast charge and slow charge are for lithium batteries, fast charge is to increase the charging current, can be filled in a short time, but the damage to the lithium battery is relatively large, slow charge is normal charging, small current, basically no harm to the battery
Under normal circumstances, the lithium battery shaver is slowly charged, and the fast charge is only used in an emergency.
