If you select non-applicable charging rate, after Auto-Detection process, charging will start at

factory pre-set charging rate at 2Amp and 2A illuminates on LED main display. 

Insert the AC plug into the mains supply (220-240 Volts AC only). 

When beep sound is heard and “2A” lights up on LED main Display, follow the below steps: 

Step 1 

– Press the Charge Rate button to select the charging power (current) 

Remark: If you know it’s 6V battery, please don’t select “7A/ 15A” as they are not applicable.

If you know it’s 24V battery, please don’t select “15A” as this is not applicable. 

Step 2 

– Press the “Battery Type” Button to select the battery type for charging. 

Step 3

– Press the “Start” Button to start the Auto-Detection Process. 

After about 10 minutes, when detection process is completed, beep sound is heard. “b6” or

“b12” or “b24” lights up on LED display, indicating the type of detected battery- 6V, 12V or

24V. Simultaneously, LED of relevant LED indicator (voltage) of 6V or 12V or 24V, and “Gel

Cell/SLA” illuminate. 

When your manually pre-set charge rate is applicable on detected type (voltage) of battery,

charging starts. 

Remark: 

If you select a non-applicable charging rate, charge will start at factory pre-set charging rate

at 2Amp and “2A” illuminates on LED main display. If you want to change the setting, please 

press “Pause” button. Then, press “Charge Rate” button for selecting the charging voltage you

want. 

Remark: For 6V Battery, only “2A” shows up on LED main display and this indicates only 

2Amp is available. 

For 12V Battery, “2A”, “7A”, “15A” illuminates in each press and this indicates 2Amp,

7Amp, 15Amp DC charging rate are available for your selection. Leave at your designated 

charging rate. 

For 24V Battery, only “2A”, “7A” illuminates in each press and this indicates only 

2Amp, 7Amp DC charging rate are available for your selection (15A is not available). Leave at

your designated charging rate. 

After above manual selection, press “Start” button and charging will start at the programmed 

parameters as your designated selection. 

NOTE: 

Battery Fault 

– A few seconds after switching on to the operating mode, the LED indicator

“FAULT” will illuminate if the following occurs: 

A.

 

Low battery voltage - < 3 V 

B.

 

High battery voltage – > 28V

C.

 

Battery short circuit or battery cell short circuit 

Under these conditions, the battery charger will stop functioning. In the event of A, B or C, the

battery may be defective. 

When the LED “FULL” illuminates, the battery is completely charged. The battery charger will

now go into maintenance mode. No attention is required until the battery is required for use 

again. 

When charging is complete

Switch off the mains supply, unplug the charger, and disconnect the alligator clamps from the

battery posts. Inspect the liquid levels in each cell and top up. If necessary, using the correct

fluid. Replace the caps. Any surplus fluid around the cell tops should be wiped off (this should

be done with extreme care as it may be acidic/corrosive).
