The product can always keep good function for battery charge protection:
1.Pre-charge design(ie. Releasing voltage protection mode): if the battery is under condition of releasing voltage, it can be charged by smaller electricity to extend the battery life.
2.Fast charge: when the battery is under normal condition, it can be charged to make the battery quickly and sufficiently charged.
3.The set voltage charger (ie.charging protection mode): when the battery voltage is up to the full value, it can be further charged by the stated voltage.
4.Stop charges: When the charge electricity is smaller than the set electricity value, it means charger is sufficient, it will stop charging automatically.
