Product Features

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, present battery voltage and present charging currency

Applicable batteries

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. (LCD shows the line between and charging currency “0.25A”.)

Three types of charging current: 0.25A, 0.5A, 1A. (According to different capacity)

Activate automatically for Li-ion batteries with protection board, which are instantaneous short circuit, and NI-MH/NI-CD batteries above 0.5V. For the batteries which cannot be activated, LCD shows the line between and charging currency “0.25A”.

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 install the batteries and plug in, LCD shows all the data and then shows line between, charging current (0.25A) and other information does not show.

B. If put the batteries into the slots, the charger can recognize the Li-ion or NI-MH/NI-CD battery automatically, and show the present voltage and battery symbol jumps. (Pressing the button momentarily can choose the charging current.)

C. Battery symbol displays dynamically
