LED Indicators
On the front panel there are also 4 LED indicators for the following function:
REVERSE – Reverse Polarity. The alligator clamps have been connected at the wrong pole on
the battery. When this occurs, simply disconnect and reconnect the alligator clamps at the
correct pole, restart the charging process.
FAULT – Battery Fault. When this illuminates, this means the battery is broken/defective. If
the battery fault display persists after resetting the charger, the battery may be faulty and
unable to charge.
CHARGING – This shows the battery is in charging process.
FULL– This shows the battery is fully charged and the battery charger is in maintenance mode.
5. Charging Operation
A) Auto- Detection
Insert the AC plug into the AC mains supply (220-240 Volts AC only).
When beep sound is heard and "2A" illuminates on LED main display, press "Start" button and
start Auto-Detection function. "6A" "12A" "24A" is rotating on LED main display. After about
10 minutes, when detection process is completed, beep sound is heard. "b6" or "b12" or "b24"
illuminates on LED main display, indicating the type of detected battery- 6V, 12V or 24V.
Simultaneously, LED of relevant LED indicator (voltage) of 6V or 12V or 24V, and "Gel Cell/
SLA" illuminates on LED main display. Then, starts charging at pre-set charging rate at 2Amp.
Remark: 1) MB-3623 is programmed and pre-set the standard settings at:
- Charging Rate: 2Amp DC
- Battery Type: Gel Cell/SLA
2) Auto-Detection function is for detecting the type (voltage) of battery.
3) During auto-detection process (around 10minutes), unit does not response
to any command even pressing any button.
If you want to change the pre-set setting as above remark 1), press "Pause" button.
Then, press "Charge Rate" button for selecting the charging voltage you want.
Remark: For 6V Battery, only "2A" shows up on LED main display and this indicates only
2Amp is available.
For 12V Battery, "2A", "7A", "15A" shows up in each press and this indicates 2Amp,
7Amp, 15Amp DC charging rate are available for your selection. Leave at your designated
charging rate.
For 24V Battery, only "2A", "7A" shows up in each press and this indicates only
2Amp, 7Amp DC charging rate are available for your selection (15A is not available). Leave at
your designated charging rate.
If you want to change the Battery Type from the pre-set Gel Cell/SLA to Regular (Lead-Acid)
or Deep Cycle, press "Battery Type" button and press again for selection from the list. Leave
at your designated battery type.
After above manual selection, press "Start" button and charging will start at the programmed
parameters as your designated selection.
B) Basic Operation - Manual Pre-set before Auto-Detection
Remark: Advantage of this operation is you can achieve quicker set-up of charging
parameters. But, please keep in mind:
For 6V battery, only 2A charge rate is applicable; for 12V battery, 2A, 7A, 15A charge rates
are applicable; for 24V, only 2A, 7A charge rates are applicable.
