Microcomputer IC controls charging process: CC/CV/Trickle charging, to make sure the battery is full charged and won’t be over charged; each slot controls independently; Mixed charging mode.
LCD instantly shows the charging process, battery voltage, time, charging current and capacity.
Discharge and test batteries’ capacity function.
Compatibility: various kinds of cylindrical chargeable batteries (Diameter: below 33mm, height: 34-72mm)
Charge 3.7V Li-ion, 3.8V Li-ion, 3.2V LiFePO4 and 1.2V Ni-MH/Ni-CD batteries
Adopt Negative voltage control technology to improve charge efficiency.
Protect opposite connection and short circuit. (LCD shows "null".)
Activate automatically for Li-ion batteries with protection board, which are instantaneous short circuit.
For the batteries' voltage below 0.5V, LCD does not display battery symbol and voltage and shows “NULL”.
Three choices for charging current can be adjusted separately, namely, 0.25A, 0.5A, 1A. (According to different capacity)
Three choices for discharging current can be adjusted separately, namely, 0.125A, 0.25A, 0.5A. (According to different capacity)
Stainless steel rail is more durable and smooth.
Worldwide voltage, suitable for the whole world.
12V car adapter is available.
Sound prompt function (Any slot completes a charging or discharging step, prompt tone rings.)

Charging Instruction Mode
A. If don’t plug in, LCD shows nothing.
B. If don't install the batteries and plug in, LCD shows all the data and then shows “null”.
C. If put the batteries in the slots, batteries' type is preliminarily identified and LCD shows the current voltage. If there is no any operation with 8 seconds, the charger will charge and show "CHG".
D. Within 8 seconds, shot press function button to adjusted charging current separately, namely, "0.25A", "0.5A" and "1.0A".
E. Within 8 seconds，long press function button to choose batteries' type, namely, "Li-ion 3.7V ", "Li-ion 3.8V", "LiFePO4 3.2V", "Ni-MH/Ni-CD 1.2V".
F. When charging, LCD shows current voltage, capacity and time and battery symbol jumps forward.
G. When finishing charging, the prompt tone rings.
Testing Capacity Instruction Mode
A. Long press to access the testing capacity mode and LCD shows “CAP”.
B. When finishing charging, the prompt tone rings. Then access to discharge status and the discharge current is half of the displayed current. Display the voltage, time and battery symbol jumps backward and capacity position begins to count the emitted capacity.
C. When reach the discharge cut-off voltage (3.8V Li-ion batteries-2.85V; 3.7V Li-ion batteries-2.7V; 3.2V LiFePO4 batteries-2.0V, Mi-NH/Ni-CD batteries-0.95V), then discharge is finished the prompt tone rings. The number in capacity position is the true capacity. And then begin to access to charging status (capacity and time are will not changed), when finishing charging, the prompt tone rings.
Charging Control Mode
A. Current Control: CC
B. -△V: 5mV
C. The total Time: 5h (Counting when each battery begins charging)
D. Max Voltage: 1.53V
Current Control: CC-CV
