• Charging rate select:
For 12V battery charge: the default charging rate is 2A, selecting the 5A or 10A charging rate by pressing the
MODE button;
For 24V battery charge: the default charging rate is 2A, selecting the 5A charging rate by pressing the MODE
button.
• Charging status LED indicators to display the battery charging level 25%, 50%, 75% and 100%.
1. Disconnect the AC power cord from the AC power outlet when fully charged. Then disconnect the
connection
with the battery.
Note:
• ALWAYS disconnect the AC power cord from the AC power outlet before connecting (or disconnecting) the
charger to (or from) the battery.
CHARGING PHASES
1. Diagnosis & Recovery
As soon as charging instruction is given to the charger, the unique function automatically checks status of
battery (detects voltage). If a deeply
discharged battery's voltage is over 4.5V ± 0.5V (for 12V battery) or 16V ± 0.25V (for 24V battery), charger
begins charging with 1.5A low current
to recover it, which terminates when voltage reaches to 10.5V ± 0.25V for (12V battery) or 21V ± 0.25V (for
24V battery) at the beginning of the
process, the charger skips low current charging and it switches over to charging mode.
2. Bulk Charging
80% of energy is returned in this phase of charging. Here charger performs in multi-stages:
For 12V battery
Select 2A slow charge, 5A medium charge and 10A fast charge rate according to practical need;
For 24V battery
Select 2A slow charge or 5A medium charge rate according to practical need;
3. Absorption
Use of a constant high current for extended periods of time risks gassing the battery, therefore a constant low
charging current is given at 1.5A
to raise voltage from 28.2V to 28.8V (for 24V battery) and 14.1V to 14.4V (for 12V battery). In this phase
complete charging up to almost 100%
is achieved. Charger switches to trickle charge phase after sensing that the battery is truly fully charged.
4. Maintenance Charge
As charger continuously monitors the terminal voltage in order to determine if a maintenance charging should
be initiated, if the battery is loaded
and/or terminal voltage falls below 25.6V (for 24V battery) or 12.8V (for 12V battery), the charger starts
maintenance charging pulse at constant
1.5A until voltage reaches to 28.8V (for 24V battery) or 14.4V (for 12V battery). Now maintenance charging is
discontinued. Cycle of trickle charging
and maintenance charging is repeated indefinitely to keep battery in good condition when it is not in use and
enables charger to be left connected
indefinitely.
