Models Targeting Lead-based Batteries
Preparation – Before Charging
General Checking
•
Check thoroughly the charger itself including all the cables show no damages
•
Take into consideration the charging instruction issued by the battery manufacturer
Charging Cable – Polarity Checking
WARNING: Check the polarity before mounting onto a plug:
•
Red cable = Plus (+)
•
Black cable = Minus (-)
DC Mains Supply Checking
•
Make sure the DC cable must not be cut, shortened or extended under any circumstances
•
Make sure the mains supply complies with the technical specification requirements of the charger
Before Connecting the Charger to the Battery
•
Make sure the charger is switched off and disconnected from the mains supply
•
<For models targeting lead-acid batteries> Select the charge profile with the slide switch; NEVER slide the switch while charging in progress
•
Then connect the terminals of the charger to the battery (Red cable to the positive (+) terminal of the battery; then Black cable to the negative
(-) terminal)
•
If the battery is built-in within a vehicle, the Black cable can be connected to the negative (-) terminal of the battery or the body of the vehicle;
make sure the connection is done with a safe distance from the fuel line and take into consideration of the battery and vehicle manufacturer
•
Finally connect the power cable of the charger to the mains supply, and switch on the charger
Charging the Battery
The charging process starts automatically and runs through the following stages:
Getting Ready: Auto Wake-up
Press the
Wake-up Button
and the charger will send out series of controlled current pulses to reactivate the BMS (if any) and bring in a voltage to
the battery for getting ready for the charging process. If no battery or defected battery pack is connected, the Red Error LED blinks. In this case,
switch off the charger and check the battery pack.
Phase 1: Soft Start
Yellow Charge LED (5) keeps on lighting. The charger regulates the initial charging current to better prolong the battery life.
Phase 2: Constant Current Charging
Yellow Charge LED (5) blinks slowly. The battery is being charged to 80% of its capacity at this stage.
Phase 3: Constant Voltage Charging
Yellow Charge LED (5) blinks quickly. The battery is being charged to its maximum capacity. When the Green Full LED (4) turns on, the charger can
now be disconnected from the battery.
Phase 4: Float Charging (for lead-based batteries only) or Auto Restart
Green Full LED (4) keeps on lighting indicate the battery has reached its full capacity. If the battery keeps connecting to the charger, auto restart of
the charging cycle will take place after 7 days or when the battery voltage has dropped to under 3.6V/cell (Li-ion Battery) or 3.2V/cell (LiFePO4
Battery).
