Main Features:
● The charging current can be selected for 500mA and 1000mA.
● It provides four independent charging slots for rechargeable batteries. The charger can charge batteries of different types and sizes and with different capacities at the same time
● The charger also includes overheat detection to protect rechargeable batteries and charger itself from overheating
● New added quick test mode to test the battery impedance
● Designed for AA (LR6) and AAA (LR3）NiCd, NiMH or 3.7V Li-ion rechargeable batteries in size type of 10440, 14500, 16340, 17335, 17500, 17670, 18490, 18650
● Operating temperature: 0 - 40 deg.C
● Max charging current: Up to 1000mA
● Power adapter: DC 12V, 3.0A (output), 100-240V, 50/60Hz (input)
● Ideal for indoor use


Parameters:
1. Voltage update rate is 30s instead of 60s.
2. 4.35V charging time can be very long because charging current is regulated in entering the CV stage at 4.12V, which is same as 4.2V type. Now 4.35V charging algorithm is changed to 4.27V.
3. There are 2 color of LED: Red for either charging in progress (constantly) or batteries' reverse polarity (flashing); green for charge complete or Li-ion CV charging status
