3. Warnings and Safety notes

IMPORTANT! Please follow these instructions for maximum safety, otherwise 
the charger and/or battery could be badly damaged and may lead to fire, 
explosion, injury or property loss.

- Never leave the charger unattended when it is connected to its power supply.

-

 If any malfunction is observed, terminate the process immediately and refer to the manual.

- 

Keep the charger away from dust, damp, humidity, rain, heat, direct sunshine and vibration.

- 

The circuit of the unit is designed to be powered by 100-240V AC only.

Voltage level: 1.2V/cell

Recommended fast charge current: 1C~2C depends on 
the performance of cell discharge voltage cut off level

0.85V/cell (NiCd), 1.0V/cell (NiMH)

Voltage level:3.6V/cell

Max. charge voltage: 4.1V/cell

Recommended fast charge current: 1C or less

Min. discharge voltage cut off level: 2.5V/cell or higher

Voltage level: 3.7V/cell

Max. charge voltage: 4.2V/cell

Recommended fast charge current: 1C or less

Min. discharge voltage cut off level: 3.0V/cell or higher

Voltage level: 3.8V/cell

Max. charge voltage: 4.3V / 4.35V / 4.4V/cell

Recommended fast charge current: 1C or less

Min. discharge voltage cut off level: 3.0V/cell

Ensure maximum charge voltage is set. This would 

usually be 4.35V but please check instructions with the 

LiHV battery. Never charge standard LiPo battery on 

LiHV setting.

Voltage level:3.3V/cell

Max. charge voltage:3.6V/cell

Recommended fast charge current: 4C or less

Discharge voltage cut off level:2.0V/cell or higher

Voltage level:2.0V/cell (Lead-acid) 

Max. charge voltage:2.46V/cell

Recommended fast charge current:0.4C or less

Min. discharge voltage cut off level:1.50V/cell or higher
