4-2. Operation and LED Indicators
Step 1.
Make sure the AC power voltage switch is correct set.
Step 2.
Make sure the AC power switch is OFF and check the charging voltage setting is correct.
Step 3.
Connect positive charging clip (red) to positive terminal of battery.
Step 4.
Connect negative charging clip (black) to negative terminal of battery.
Step 5.
Press I on the AC power switch to turn charger ON.
Step 6.
All the LED light up for 2 seconds. Afterward, red LED lights up for 5 seconds. The
rectangle LED indicates the set charging voltage.
Step 7.
Charging begins. The relay in the charger turns ON. A clink sound is normal.
Step 8. Yellow round LED: light up constantly
The LED lights yellow for 25 seconds means charging just begins and is charging slowly. At the
time, rectangle LED all light up initially, and turn to display the percentage of battery capacity
charged by the amount it lights.
Step 9. Yellow round LED: flash slowly
The LED turns to flash yellow slowly means it is charging in a constant current, the bulk charging
stage. At the time, the numbers rectangle LED light up increases with the capacity has been
charged.
Step 10. Yellow round LED: flash quickly
The LED turns to flash yellow quickly means it is charging in a constant voltage, the absorption
charging stage. At the time, the numbers rectangle LED light up increases with the capacity has
been charged.
Step 11. Yellow round LED: flash very quickly
The LED turns to flash yellow more quickly means it is about to turn to floating charging stage
soon.
Step 12. Green round LED: flash slowly
The LED turn to green means it has turned to the floating charging stage. Battery is full charged.
Step 13. Green round LED: flash quickly
The LED turn to flash green quickly means it is in the floating charging stage and charging
current is beyond 0.5A.
Step 14.
Battery charging is finished. Follow steps below to remove the battery.
Turn charger OFF. The relay in the charger turns OFF. A clink sound is normal.
Remove the black charging clip from battery, then remove the red one.
