1. In a certain voltage, the battery of charger can maintain a constant, and can control itself when the battery is full.
2. Charging current

(1) Battery voltage under 3.4V, current 850mA-900mA

(2) Battery voltage to 3.5V-3.6V, current 650mA-700mA

(3) Battery voltage to 3.9V-4.1V, current 500mA-550mA, up to the full of battery, rate of 98%-100%.

(4) The charger use the way of PWM, which is high voltage, large current-mode and constant current one. People can enjoy a fast and efficient charging battery.

(5) Rechargeable battery’s voltage should be above 2.7V.If not, the charger will be not used. Certainly, after a renovating of the battery, you can adopt other ways and charge it.

(6) The charger with anti-battery-inversion circuit ensure the safe of the charge and the battery.

(7) Rechargeability:16340,18650,25500,26650,26700

(8) Charging time:4h-5h(like 2 pieces of 25500 battery 3000mAh).

(9) The charger can be used for 3.2V iron phosphate lithium battery and 3.7V lithium ion battery. And you only exchange the switch to corresponding location.
