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, charging current and capacity.
Compatibility: various kinds of cylindrical chargeable batteries (Diameter: below 26mm, height: 34-70mm)
Charge 3.7V Li-ion or 1.2V Ni-MH/Ni-CD batteries
Adopt Negative voltage control technology to improve charge efficiency.
Protect opposite connection and short circuit. (Do not display battery symbol and voltage.)
Activate automatically for Li-ion batteries with protection board, which are instantaneous short circuit. For the batteries' voltage below 0.5V, LCD shows “NULL”.
Two types of charging current: 0.5A, 1A. (According to different capacity)
Two types of discharging current: 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.)
USB 5V Output Mode (used as Portable Charger for mobile or pad etc.)
AC 110-240V 50/60Hz
DC 12V 1A
DC 4.2V±0.02V 0.50A±30mA*2 1.0A ±50mA*2
DC 1.48V 0.50A±30mA*2 1.0A ±50mA*2
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 line between, “NULL”, charging current (0.5A) and “CHG”.
C. If put the batteries into the slots, the charger can recognize the Li-ion or NI-MH/NI-CD battery automatically, show the present voltage and charging capacity and battery symbol jumps forward. (Pressing the button momentarily can choose the charging current.)
D. 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 press the button momentarily can choose the discharging current. Display the voltage and battery symbol jumps backward and capacity position begins to count the emitted capacity.
C. When reach the discharge cut-off voltage (Li-ion batteries-2.7V; Mi-NH/Ni-CD batteries-0.9V), 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, when finishing charging, the prompt tone rings.
USB Instruction Mode
A. When putting 1 Li-ion battery and no other input, the max output current of USB is 1000mA.
B. When putting 2 Li-ion batteries and no other input, the max output current of USB is 2100mA.
When no inputting, please do not reverse the battery, otherwise it will damage the charger.
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
