Specifications
 
OPERATION INSTRUCTIONS
Connecting the terminal rings/clamps directly to the corresponding connectors on the battery posts.
Note:
Make sure correct polarity connection before plugging in the AC power. Position the RED terminal on the POSITIVE post connectorPosition the BLACK terminal on the NEGATIVE post connector
2.  Connect the AC power cord with the AC power outlet.
3.  Disconnect the AC power cord from the AC power outlet when fully charged. Then disconnect the conne
ction 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 PHASES1. 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 24V battery
Select 2A slow charge or 5A medium charge rate according to practical need;For 12V battery
Select 2A slow charge, 5A medium charge and 10A fast 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.
