Connection & Selection of Battery Type
Plug in the charger to AC mains (200- 240V) wall socket.
The display LED light up one by one as charger goes through a series of self checks. Then all lights
are on together and all LEDs are off to indicate the end of self checks except the “Standby” indicator.
There is no voltage at the output terminals to safeguard the user.
Connect the red output lead to the positive terminal of the battery and the black lead to the negative
terminal.
The last used battery type LED is solid on and the “Standby” LED blinks to indicate that the charger is
now ready for a new selection of battery type.
User has 1 minute to select the new battery type. If no selection is made, the battery charger will
revert back to its last used battery type at the end of one minute waiting time and the Standby LED
becomes solid.
The are 5 charging modes to select: LEAD/ LEAD COLD/ AGM/ AGM COLD/ Lithium FePO4. The
Cold Charge has a higher voltage applicable for LEAD & AGM battery in cold weather.
Select the desired battery type by quick presses on the Mode button within 1 minute.
Each quick press will change selection cyclically as shown by the LEDs in following cyclic manner.
“LEAD”
→
“ LEAD cold (flickering led)”
→
“AGM”
→
“AGM cold (flickering led)”
→
“Lithium Fe P04”
→
“LEAD”.
Note: There is no cold temperature setting for Lithium Fe PO4.
Once the Standby LED stops flickering and becomes solid, the charging operation starts and Mode
button becomes inactive to prevent any new battery type change.
**
To change the battery type during a charging operation either switch off the AC or
reconnect the battery and select the new battery type after self check.
LEAD & AGM Battery
After selection of battery type to LEAD or AGM The Charger first checks the battery’s
condition ,Charger will then enters into
“Charge Mode” and finally to the
“Float/ maintenance Mode” when battery is fully charged.
Charging Stages for LEAD & AGM
Bulk:
This charges the battery up to about 80% full.
Soft Start Bulk:
when battery is detected to be heavily discharged , charger will only deliver 4A
current until battery becomes ready to go normal bulk charge stage.
The charger delivers max 8A constant current until the battery voltage rises to a
threshold values. There is a thermal control in gradual decrease of charging current
at high operation temperature.
Absorption:
PWM charges to 100%. The terminal voltage is kept constant at set level. Battery
charger delivers current pulses to the battery in varying pulse periods. When the rise
time of pulses decreases to a set value, charger switches to Float Mode. The maximum
total charging time of Bulk and Absorption is 40 hours at which the charger will shut
down.
Float:
PWM maintenance charging and cycle charging.
In this mode the charger does not deliver current when battery voltage is above a set voltage.
When battery voltage drops below the set voltage, charger will deliver small current until the
battery voltage rises to about 13.5V. Then the maintenance charging cycle repeats.
In the case of battery voltage drops more than 12.2V due to external load or otherwise, the
charger will start a new charging cycle of Bulk, Absorption and Float.
