1. Check the battery's initial state, voltage, SoC and state
of health to ensure the stability of the battery before
charging.
2. Charge the battery with pulse current to break down the
sulfates that have built up over time in the aging battery
to extend life.
3. Charge the battery with a low current to prepare for the
high-current charging.
4. Charge the battery with three stages of constant current
that gradually rise to optimize charging.
5. Charge the battery with preset current until it reaches
80%.
6. Trickle charge the battery until it reaches 90%.
7. Maintain the voltage at preset value until the charging
current drops to 12.5% of the maximum value and keep
charging the power to 95%.
8. Charge at 12.5% of the preset maximum current until the
battery is charged to 100%.
9. Check if the voltage is lower than preset value. If it is, turn
back to step 8.
Charging Steps
Before starting the charging, make sure you know about the
necessary information of your battery and select the
appropriate charging mode.
1. Connect the charger's plug to an appropriate socket.
2. Connect the clamps to the corresponding battery
terminals, that is, the red clamp to the positive (+) and the
