3.2. PREPARATIONS FOR OPERATION
POSITIONING THE APPLIANCE
The maximum ambient temperature and relative
humidity limits not to be exceeded are +40°C and 85%
RH, respectively. Position the appliance where good air
circulation is ensured. Keep the appliance away from any
hot surfaces. Always operate the appliance on a level, firm,
clean, fireproof, and dry surface and out of the reach of
children and individuals with reduced mental, sensory and
intellectual capacities. Position the appliance where the
mains plug can be reached at any time. Make sure that the
mains power ratings match the data on the rating plate! Do
not operate this appliance under a motor vehicle's engine
bonnet (hood) or standing directly atop of the battery!
3.3. OPERATING THE APPLIANCE
3.3.1. CONTROL PANEL FEATURES
a. Standard charging indicator (12V STD) – the standard
charging mode for all battery types, except for AGM.
b. AGM standard charging indicator (12V AGM) – the
standard charging mode for AGM batteries.
c. Low temperature charging (the snowflake icon) –
battery charging in cold weather, e.g. outdoor (-20°C
to +5°C)
d. Standby indicator (12V M) – standby mode of the
connected battery to keep it in good health, e.g.
during extended standstill of the vehicle; low-current
charging or charging of low-capacity batteries. This
mode is recommended for seasonally moved vehicles,
like motorcycles, classic cars or motor homes.
e. Deep-discharge reconditioning indicator (RECON) –
use only for traditional lead-acid batteries!
CAUTION! This charging mode uses a charging
current value higher than normal and the battery
must be disconnected from the vehicle's electrical
system! Do not use this charging mode for more than
4 hours without interruption.
This charging mode can be selected by pressing and
holding the MODE key for 5 seconds.
f. Charger/battery error alarm indicator (the warning
sign icon) – this indicator comes on whenever the
polarity of the charger lead connections is reversed or
the charger leads are shorted to one another.
g. 12V system supply indicator (SUPPLY) – this mode
simulates the DC power supply from a battery for the
vehicle's electrical system, which is very convenient
when unhooking the battery from the vehicle's
electrical system; a sustained voltage supply for the
electrical system prevents reprogramming of the
vehicle computer, alarm, radio head unit, clock, etc.
It is extremely convenient in the latest vehicles which
feature complex electronic systems. If the terminals
are shorted in this mode, the display messages "Lo V".
h. Battery state of charge indicator – this progress
bar light indicator provides real-time display of the
battery's state of charge. If the indicator is flashing
and more of its segment come on, the battery is being
recharged. Each bar of the indicator corresponds to a
state of charge – the more bars are on, the higher is
the state of charge of the battery. When all bars of the
indicator are on, the battery is at full charge.
Rev. 18.10.2022
i. Message display – reads the actual battery voltage,
e.g. "14.0V"; "BAt" – battery malfunction or battery
voltage below 3.5 V or above 15 V (and the battery
cannot be charged); "FUL" – the battery is at full
charge; "Err" – charger error (reversed polarity or
short-circuit).
3.3.2 CONNECTING THE BATTERY CHARGER AND
CHARGING
CAUTION! Before connecting the clamp leads to the battery
post, the power cord must be unplugged from the mains!
IMPORTANT! The terminal/clamp colours is not arbitrary;
the colours are standard designations of the electrical
polarity in most vehicles. It is recommended to charge the
battery unhooked from the vehicle battery cables, though
it is not absolutely necessary (do not attempt this in the
RECON mode). If the battery is to be recharged while
connected to the vehicle battery cables, disconnect/isolate/
turn off all electrical loads in the vehicle, like the central lock
system, the alarm, the cabin courtesy lights, the radio head
unit, etc. The engine shall be turned off. The installation
location of the battery might not be easily accessible under
the engine bonnet (hood). Some motor vehicles have the
battery installed inside of the wheel arch, beneath the wiper
cowl, inside of the cabin (below the floor carpet or a seat),
or in the boot (trunk – below the trunk floor, in the spare
wheel recess, or beneath the trunk side trim). If the battery
is not installed under the bonnet (hood), its charging is
facilitated with extension terminals under the bonnet (hood).
See the owner's manual for the vehicle or contact the nearest
dealership service for more information. The battery charger
stores the last operating mode used (with the exception of
RECON and SUPPLY) when unplugged from the mains.
• First, connect the red (positive) charger lead clamp to
the positive (+) terminal post of the battery; second,
connect the black (negative) charger lead clamp to
the negative (-) terminal post of the battery or to the
ground (GND). If the battery is not unhooked from the
vehicle's battery cables or has extension terminals for
charging under the bonnet/hood, attach the charger
lead clamps to these connections in the same order.
Make sure that the charger lead clamps hold the
battery cable terminals/extension terminals securely.
CAUTION: Some vehicles have the ground (negative)
reversed, with the positive pole attached to the vehicle
body. In this case, first connect the black (negative)
charger lead clamp to the battery negative post/
terminal; second, connect the red (positive) charger
lead clamp to the vehicle ground which must be away
from the battery and all fuel lines.
• Place the battery charger next to the vehicle without
straining the clamp leads and keeping them safe
from pinching and crushing, and away from all hot
components of the vehicle (it is highly recommended
to leave the engine stopped to cool down before
charging the battery). Keep a clearance around the
battery charger and its lead clamps to ensure good air
ventilation.
• Plug the power cord to the mains. The display reads
the actual voltage of the connected battery, and the
charger will first automatically go into the standard
charging mode.

• Operate the MODE key on the control panel to choose
the charging mode the indicator of which comes on
and the charger will begin charging.
IMPORTANT! The battery reconditioning mode
(RECON) can be selected by pressing and holding the
MODE key for 5 seconds. Repeat to exit this mode.
• The indicator of the selected charging mode comes on
and the state of charge indicator bars will successively
come on until the battery is fully recharged and the
display reads "FUL". The charger will float the battery
to maintain a state of charge between 95-100%.
CAUTION: If the battery charger indicates a full
battery charge after already after several minutes
into charging of a low battery, the battery needs
replacement for a new one.
IMPORTANT! The battery charger housing can be hot
during charging. This is normal.
• When done charging, first unplug the power cord
from the mains.
• First, disconnect the charger negative (-) lead clamp
from the battery post/extension terminal/body
ground; second, disconnect the charger positive (+)
lead clamp from the battery post/extension terminal.
IMPORTANT! If the battery's positive terminal is on the
vehicle's body, first remove the disconnect the charger
positive (+) lead clamp and follow by disconnecting
the charger negative (-) lead clamp.
• Do not leave the battery charger leads connected
(even if unplugged from the mains), or the charger
will slowly drain the battery.
3.3.3. CALCULATING THE INDICATIVE CHARGING TIME
The battery charging time in the standard or low
temperature mode largely depends on the remaining state
of charge and the battery capacity. If the battery has been
fully (deeply) discharged, its recharging time to 80% of
capacity can be calculated from the following formula:
• Ch. T. – indicative charging time (hours)
• Batt. Cap. – battery capacity (Ah, amp-hours)
• Chg. Current – battery charging current (amperes);
usually its optimum value is 1/10-1/6 of the battery
capacity (Ah).
3.4. CLEANING AND MAINTENANCE
a) Before cleaning, adjustment or replacement of
accessories, and when the appliance is not in use,
unplug the power cord from the mains and leave the
appliance to cool down completely.
b) Use non-corrosive agents only for cleaning the
surfaces.
c) Store the appliance in a dry and cool place, protected
from moisture and direct sunlight.
d) Do not spray the appliance with a stream of water and
do not immerse it in water.
e) Clean the ventilation ports with a brush and
compressed air.
