MoDe 2 DescriPtion (14.4V/4.0a)
4.4.1 This mode is mainly for charging large batteries with a
capacity over 14Ah in normal conditions. Press the
MODE button until the LED adjacent to the car symbol
is illuminated. Charging will automatically begin with a
current of 3.8A ± 10% and the 'charging' LED will
illuminate. This LED will remain on throughout
the entire charging process until the battery is fully
charged up to 14.4V ± 0.25V. At this stage the
'charging' LED will extinguish and the 'fully charged'
LED will illuminate. The trickle charge current now
becomes available for battery maintenance.
4.5
MoDe 3 DescriPtion (14.7/4.0a)
4.5.1 This mode is mainly for charging large batteries with
a capacity over 14Ah in cold conditions or for charging
several AGM batteries with a capacity over 14Ah.
Press the MODE button until the LED adjacent to the
ice crystal symbol is illuminated. Charging will
automatically start with a set delay with a current of
3.8A ± 10% and the 'charging' LED will illuminate. This
LED will remain on throughout the entire charging
process until the battery is fully charged up to 14.7V
± 0.25V. At this stage the 'charging in progress' LED
will extinguish and the 'fully charged' LED will
illuminate. The trickle charge current now becomes
available for battery maintenance.

MoDe 4 (desulphurization)
4.6.1 When the charger is connected to a battery and before
the charging process begins the charger automatically
detects the voltage of the battery. If the voltage is
below 7.5V the charger will not start the normal
charging process due to its internal safety circuit. If the
voltage is in the range of 7.5V ± 0.5 to 10.5V ± 0.5 the
charger will initiate pulse charging ‘repair mode’. Once
the voltage of the battery rises to 10.5V ± 0.5 the charger
reverts to the previously selected normal charging
mode and charging takes place at the normal rate.
Most drained batteries can be charged and used again
using this procedure.
4.7
fauLt Protection
4.7.1 In the case of short circuit, open circuit, reversed polarity
or battery voltage below 7.5V ± 0.5, the charger will
turn off the electronic system and revert to standby
mode. Additionally the ‘Fault’ LED
(!) will illuminate.
The fault must be identified and resolved before any of
the charging modes are initiated.
5.1 The
sMc02.V2 charger has a nine step fully automatic
charging cycle as shown in Fig.3 above, which is
indicative of the typical charging curve for a battery.
5.2 PHases 1 through 5 DiaGnosis & recoVery:
As soon as one of the charging modes is selected the
diagnostic function automatically detects the condition
of the battery i.e. voltage. If the voltage of a deeply
discharged battery is over 7.5V ± 0.5V the charger
begins to pulse charge with a small current to recover
it. Pulse charging ceases when the voltage reaches
10.5V ± 0.5V. If the voltage detected is over 10.5V ±
0.5V the charger skips pulse charging and switches to the
preselected charging mode.
5.3 PHase 6 BuLK: Up to 80% of the charge is delivered
in this phase.
5.4 PHase 7 aBsorPtion: A constant low charging
current raises the voltage from 14.1V to 14.4V over a
period of time without gassing the battery. In this phase
complete charging up to almost 100% is achieved.
When full charge is reached the charger switches to
phase 8 and 9.
5.5 PHase 8 & 9 Maintenance cHarGe: If the battery
is loaded and/or the voltage across the terminals drops
below 12.8V, the charger starts a maintenance
charging pulse at a constant 0.8A until the voltage
reaches 14.4V at which point the maintenance charge
is turned off. The charger continues to monitor the
battery condition and will cycle between trickle charge
and maintenance charge indefinitely to keep the
battery in peak condition. The charger can be left
connected to the battery in order to perform this
maintenance function.

All figures offered as a guide only. The charger is
automatic and requires no measurements by the user.
6. Maintenance
6.1 This charger requires no specific maintenance other
than cleaning which should be done with a dry cloth.
Do not use any solvents or cleaning agents on the
casing.
6.2 Ensure that the charger is unplugged from the mains
before installing or performing any maintenance.

oVerHeatinG Protection
4.8.1 If the charger becomes too hot during the charging
process or due to extreme ambient temperatures the
power output is automatically reduced to a trickle
charge to protect the unit. Once the temperature drops
the charger will increase the power output automatically.
