UNDERSTAND THE HAZARD INVOLVED.
CHILDREN SHALL NOT PLAY WITH THE
APPLIANCE. CLEANING AND USER
MAINTENANCE SHALL NOT BE MADE BY
CHILDREN WITHOUT SUPERVISION.
•Make sure that the charger switched to maintenance
mode after normal charging is completed, if you want to
leave it unattended and connected for a long time. If it
does not leave charge mode after maximum time,
disconnect charger from the battery. See technical
specifications below for info about time limit.
•All batteries will eventually fail. If that happens during
charging, the charger will detect it, but there may be
some rare faults in the battery, so do not leave it
charging unattended for longer periods of time.
•You need to have read and understood the full context
of this user guide before you start using the battery
charger.
GETTING STARTED
1. Connecting the charger: Connect the charger to the
supply mains. A flashlight on the top will automatically
turn on to assist you in dark situations. The battery
terminal not connected to the chassis has to be
connected first. The other connection is to be made to
the chassis, remote from the battery and fuel line. The
red clamp should connect to the positive (+) pole of the
battery and the black clamp to the negative (-) pole.
Please note that the vehicle manufacturer may have
their own recommendations for connection points for

battery chargers, in which case you should follow those.
For stand-alone batteries: Connect the charger to the
supply mains. Connect the red clamp to the battery’s
positive (+) pole, and then the black clamp to the
battery’s negative (-) pole.
2. When all 4 charge level indicators are constantly lit, the
battery is fully charged and has entered maintenance
mode. The battery will be kept fully charged as long as
charger is plugged in to the mains.
INSTRUCTIONS
1. Connect the charger as explained in GETTING STARTED,
point 1, above. The 4 LEDs in the battery symbol will
flash for a few seconds. Then it will start to analyze the
battery, and the charge level indicators will start rolling
from “battery empty” to “battery full”. After a little
while, the LEDs will have a steady light indicating the
current battery charge level, and when charging is
finished all 4 LEDs will be lit.
2. If the red light below the level indicators is lit constantly,
it means “FAULT” and indicates wrong connection to
battery (reversed polarity). Disconnect clamps from
battery, and reconnect them correctly as said
mentioned above.
3. When charging, the yellow and green indicators will
show the current charge level of the battery, when
constantly lit.
Lamp lit –Battery not connected
Lamp+Red –wrong polarity to battery
Yellow+Green rolling –Charging
Yellow+Green constant–fully charged
Yellow+Green+red constantly lit -
charging timeout (charge cycle finished
without reaching full charge)
4. After charging, disconnect the battery charger from the
supply mains. Then remove the chassis connection and
then the battery connection.
For stand-alone batteries: After charging, disconnect the
charger from the supply mains. Then remove the black
clamp and then the red clamp.
5. By leaving the clamps on the battery after charging, and
mains plugged in, the charger will automatically switch
to maintenance mode as long as it is connected to the
mains.
6. To stop or interrupt charging, unplug the supply mains,
at any time, and then remove clamps.

CHARGING CURVE
Reference charging time (hours) to 85 % capacity.
Time varies with different batteries and conditions.
25Ah: 5h 75Ah: 10h 100Ah: 18h 150Ah: 26h
Note: If left connected, it is programmed to restart from
Step3 after 7 days, to refresh the battery.
SPECIAL FEATURES
Flashlight: There is a built-in flashlight in the front of the
charger, on the top of casing just in front of the battery
symbol. It will automatically turn on when the charger is
plugged in. It will switch off if connected to a battery.
Temperature sensor: The temperature affects the batteries
ability to receive charge. This product has a sensor in the
black clamp, which compensates for temperature variations
to give optimal charge in cold as well as warm conditions,
avoiding the common problem of insufficient charging in cold
weather and over-charging at high temperatures.
FAULTS INDICATIONS & TROUBLE-SHOOTING
1. Fault: Lamp+Red light (constant) is lit, Clamps
connected to the battery.
Probable cause: Reversed polarity protection
activated due to clamps connected to wrong
battery poles.
Action: disconnect the charger from the mains, re-
connect the clamps correctly and connect mains
again.
Probable cause 2: The battery voltage is too high
(over 17V).
Action: Replace battery with a 12V lead-acid type.
2. Fault: Charging does not start and flashlight does
not turn off. None of the battery level lights are lit.
Probable cause 1: Clamps do not have good

connection to battery.
Action: Check that clamps are connected well to
metal on both battery poles. Check that connector
on the clamp cable is pushed all the way into
connector on charger’s connector.
Probable cause 2: The battery voltage is too low
(<5V) for the charger to detect it, and it will not
start. This may be because the battery is worn or
faulty or has been overly discharged.
Action: Replace the battery, or you can try to
connect a 12VDC power supply to the battery for a
while to see if the battery voltage can be increased
>5V and then reconnect the charger.
3. Fault: Charging started normally, but did not
complete, and stopped. Yellow+Green+Red lights
are lit.
Probable cause 1: The battery has a fault that does
not permit it to be charged, e.g. a short circuit.
Action: Replace the battery (with lead-acid type).
Probable cause 2: Parallel load. If there is an
equipment using current from the battery while
charging, the charger may not be able to charge
the battery within the safety time limit set for
safety reasons.
Action: Disconnect the parallel load and repeat
charging or purchase a more powerful charger that
can handle the extra load.
Probable cause 3: Battery is too large and could
not be charged within the set safety time limit.
Action: Repeat charging.
4. Fault: The flashlight does not come on when the
charger´s power cable is plugged into the mains
socket.
Probable cause: No power in mains socket. Or the
flashlight LED is broken. (You can still use the
charger but it will be without flashlight function).
5. Fault: The charger is wrongly indicating repeated
startups; the 4 battery level indicator LEDs are
blinking for a few seconds, then turns off, and this
repeats itself.
Probable cause: The charger cannot identify a
chargeable battery. It can happen when the
current to the battery is <10mA and has high
internal resistance. Battery could be defect, too
small, or very cold.
Action: Replace the battery.
6. Fault: The charger is wrongly indicating repeated
startups; the 4 battery level indicator LEDs are
blinking for a few seconds, then turns off, and this
repeats itself, even when a battery is not
connected.
Probable cause: The charger’s spark protection

may be faulty, which can cause sparks that can
ignite explosive gases.
Action: The charger shall be discarded.
MAINTENANCE
The charger is entirely maintenance-free. It has no user-
serviceable parts. Opening the charger will void the warranty.
The case may be cleaned using a soft, damp cloth. The
charger must be disconnected from the mains when being
cleaned.
ACCESSORIES
The charger comes with clamp cables. (Ring terminal cables,
which can be used for fixed installations, can be ordered
separately.) To change cables, press the unlock flange on the
connector and pull it out. Connect the desired new cable.
Push it all the way. The flange should lock it.
