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 cannot be activated, LCD shows “null”.
Stainless steel rail is more durable and smooth.
Worldwide voltage, suitable for the whole world.

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, the charger recognizes Li-ion and Ni-MH batteries. If there is no any operation with 8 seconds, the charger will charge in present battery type and the LCD shows the charging process, battery voltage, battery type and present charging capacity.
D. Within 8 seconds press “SLOT” button to adjust the slot and press “MODE” button to choose battery type.
E. Battery symbol displays dynamically
①Present charging status
②Present battery capacity percentage as follows:
Blank Battery Symbol
The First Grid Lights
The Second Grid Lights
The Third Grid Lights
The Fourth Grid Lights
The Fifth Grid Lights
③When charging, the blank battery grids light gradually.
F. 120s later backlight will be out automatically and press the “SLOT” or “MODE” button, the backlight will turn on.
