Where appropriate, if the battery has been removed for charging, replace it and reconnect the
cables.
Protection
a)
Reverse Polarity
If the alligator clamps are connected improperly to the battery terminals, the reverse polarity
LED will indicate the reversed polarity; warning buzzer will also sound and “E1” illuminates on
LED main display. When this occurs simply disconnect the battery charger from the AC power
and connect the alligator clamps correctly to the battery terminals. Reconnect the charger to
the AC power.
b)
Over-Heat
If internal temperature of the unit is too high, warning buzzer will sound and “E3” illuminates
on LED main display. When this occurs simply disconnect from AC power mains and battery.
Let the unit cool down before charging again.
c)
Over-Current
If output current is too high, warning buzzer will sound and “E4’ illuminates on LED main
display. When this occurs, please disconnect the unit from AC power mains and battery.
Try to re-set and recharge. Or set to lower output.
d)
Short-Circuited
If “+” and “-” alligator clamps are shorted or voltage of battery is below 3V, warning buzzer
will sound and “
[3.0
” illuminates on LED main display. When this occurs, please disconnect
from AC power mains and check the polarity connection. If polarity connection is correct,
please check the battery.
e)
Voltage of battery >28V
If voltage of battery is over 28V, warning buzzer will sound and “
]28
” illuminates on LED
main display. When this occurs, please disconnect from AC power mains and battery. Don’t try
to recharge that battery.
f)
Detection Failure
If type (voltage) of battery is failed to be detected or the type of battery is not suitable to be
recharged by MB-3623, warning buzzer will sound and “
E2
” illuminates on LED main display.
When this occurs, please check the type of battery. For example, if the battery is lithium or for
electric car, do not charge with MB-3623. If type of battery is applicable for MB-3623, please
try to re-set and recharge. If situation persists, battery may be faulty.
It is essential to keep your battery regularly charged throughout the year, especially during
the winter months. In the winter the effectiveness of your car battery is reduced by the cold.
Oil is thick. Engines are difficult to start as the heater, windscreen wipers and lights are all
draining power. It is at this time that batteries have to be at peak power. If your battery is not
regularly maintained and kept fully charged, it can cause problems and a possible breakdown.
Listed are some helpful hints on how to keep your battery healthy in conjunction with your
Battery Charger.
Faulty Cells
Batteries are usually made with six cells. One of these cells can deteriorate or get damaged. If,
after several hours charging your battery is still flat, you should test the battery. Take
hydrometer readings from each cell in the battery. If one reading is lower than the others, this
could indicate a faulty cell.
