Condition
Cause
Solution
01
The voltage of the
battery is lower than
10V after 10 minutes
charged.
There is short circuit in the battery. Replace the battery. Dispose of the
defective battery in a suitable manner.
There is load connected to the
battery.
Disconnect the load from the battery.
The voltage of the bat-
tery is lower than 13V
when the battery goes
into float charge.
Recondition the battery.
02
The voltage between
the two clamps is higher
than 19V.
The voltage between the two
clamps is too high.
Check the battery. The voltage of
battery should be in the range of 12V
to 14V.
03
The charge current is
too high.
This happens when an external
voltage source is connected to the
battery during charging process.
Please disconnect battery from any
external components.
04
The temperature of the
charger is too high.
This charger ambient temperature
is too high.
Clean dirty ventilation openings or re-
move objects covering the unit. Place
the unit in a cooler location.
05
The battery charger
does not go into float
charge.
The charging current is too low.
Choose the higher current to charge
the battery.
Bad battery.
Replace the battery. Dispose of the
defective battery in a suitable manner.
2.
Reverse Polarity LED Indicator - when the battery clamps are connected incorrectly the red LED illumi-
nates.
3.
Battery Recondition Indicator - when the battery is reconditioned, the yellow LED illuminates. The charger
will recondition the battery only when the battery is in a state of “deep discharge”. It cycles every 4±0.5h until
the battery is no longer “deep discharged”. If it cycles 5 times and the condition has not changed, there will be
the code F01 present on the display panel, indicating an error. Please replace the battery.
4.
Charging State LED Indicator - when battery is charged at a constant current or a constant voltage, the
green LED flashes. When the battery is fully charged or goes into float charge, the green LED illuminates.
5.
Current Indicator - When the display panel indicates the present current, the current LED indicator illumi-
nates.
6.
Voltage Indicator - When the display panel indicates the present voltage, the voltage LED indicator illumi-
nates.
7.
Battery Capacity - When the display panel indicates the battery capacity, the LED indicator illuminates.
Code
Condition
LO
The capacity is lower than 50%
80
The capacity is around 80%.
FUL
Battery is full charged
8.
Display Button Switch - You can choose the display mode on the panel by pressing the button.
9.
Automatic – The charger automatically selects the correct charging current for your battery
10.
2A Charge current Indicator – The charging current is set to 2A.
11.
8A Charge current Indicator – The charging current is set to 8A.
12.
12A Charge current Indicator – The charging current is set to 12A.
13.
