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 20Ah.
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’ LED will extinguish
and the ‘fully charged’ LED will illuminate. The trickle
charge current now becomes available for battery
maintenance.
4.6
MoDe 4 DescriPtion (7.5/4a)
4.6.1 This mode is mainly for charging all types of 6 volt
batteries with a capacity over 14Ah. Press the MODE
button until the LED adjacent to the 6V battery symbol
is illuminated. Charging will automatically start with a set
delay and the ‘charging’ LED will illuminate. This LED
will remain on throughout the entire charging process
until the battery is fully charged up to 7.5V ± 0.25V.
At this stage the ‘charging’ LED will extinguish and the
‘fully charged’ LED will illumniate. The trickle charge
current now becomes available for battery
maintenance.
4.7
MoDe 5 DescriPtion (cal)
4.7.1 This mode is for lead calcium or a battery below *10.5
volts with no capacity to absorb charging current, the
charger will automatically raise the output up to *17
volts. The Mode 5 LED will illuminate and flash, the
‘charging’ LED will illuminate. If the battery cannot be
recovered within 2 hours the “Fault”
(!) LED will
illuminate. The battery may require replacing.
4.8
fauLt Protection
4.8.1 In the case of a 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.
4.9
oVerHeatinG Protection
4.9.1 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.
5.1 The
sMc03.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 PHase 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.

automatic and requires no measurements by the user.
