Function introduction

• PK-8146 charger adopts advanced charging control program to monitor battery voltage in real time. It adopts the most suitable nickel-hydrogen battery constant current pulse charging scheme to ensure the best charging effect of the battery. It has a triple stop charging judgment program:

1. Battery negative voltage (-△V) stop charging: According to the characteristics of NiMH battery, when the battery is fully charged, when the voltage reaches a certain voltage, the battery voltage will decrease, and the charger will monitor this change in real time. After the battery is connected for 15 minutes, the voltage is greater than or equal to 1.40V and begins to enter -ΔV detection. It is detected that the voltage is decreased after 3mV or above.
2. Battery zero-growth voltage stop charging: When the battery voltage is greater than or equal to 1.40V, it will enter the zero-voltage growth detection. If the battery voltage is continuously detected for 40 minutes or longer, the same voltage value will remain unchanged.
3. Maximum voltage stop charging: According to the characteristics of nickel-metal hydride batteries and summarizing some batteries with poor battery characteristics on the market, the limit battery voltage is up to 1.53V, and the battery voltage exceeds 1.53V.

• Micro USB interface input
• Microcomputer control technology, intelligent realization of four slots independent charging
• One red and green two-color LED in each slot for instant visual display of charging status
• Can access 1 to 4 AA or AAA NiMH batteries
• Using -DV control technology, charging efficiency is higher;
• Reverse battery protection, short circuit protection
