Important: Ensure that the charger is correctly prepared
and the battery is connected correctly before charging
the battery.
Important: Continually monitor the battery voltage and
adjust the charging output current during charging.
8.1 Charging Times
Calculate the approximate charging time for a battery
using the following equation:
Charging time/hours =
Capacity in Ah (battery)
Charger output (Amps)
For example, a 50Ah would require roughly 3 hours to
charge on a 16A current.
As the battery nears a full charge, the ammeter (3) needle
will approach the “0” value of the scale. When the needle
is near the “0”, it is fully charged. Disconnect the battery
immediately.
Important: Charging times are subject to the battery
condition. Partially charged batteries require less
charging time than fully discharged batteries.
8.2 Charging Procedure
1. Ensure that the plug tted to the appliance is
appropriate for the intended operation; see 6.1
Connecting a Plug.
2. Connect the charger to the battery;
see 7. Connecting a Battery.
3. Set the mode selection dial (11) to position 1 [charge
icon] and connect the charger to the power supply.
4. Monitor the battery voltage with a suitable meter (not
supplied).
− As the battery voltage increases, move the mode
selection dial to positions 2 and 3 to increase the
output.
− When the battery reaches 12V or 24V as
appropriate, move the mode selection dial to
position 4, 5 or 6 as appropriate for the nal part
of the charge.
Important: In modes 4, 5 and 6, no current is
applied until the timer becomes active.
CAUTION! The current may ONLY be
increased if a 16A plug has been tted to
the product.
5. Rotate the timer dial (13) to the appropriate time
setting (max. 60mins).
6. The charging current remains active only while the
timer is active.
7. When the timer runs down, the current stops and a
bell sounds.
8. Move the mode selection dial to the 0 position and
disconnect the mains power supply.
9. Disconnect the battery from the charger in reverse
order and in accordance with the manufacturer’s
instructions.
8.3 Notes on Charging
• The machine can be used to charge multiple batteries
simultaneously:
− The 12V terminal can be used to charge a single
12V battery or multiple 12V batteries wired in
parallel.
− The 24V terminal can be used to charge two 24V
batteries wired in series.
Important: DO NOT attempt to charge batteries of
dierent types or with dierence capacities or levels of
charge at the same time.
WARNING! Simultaneous battery charging must
ONLY be undertaken by a qualied electrician
or an otherwise experienced and competent
person.
• The fast charging option applies low and high current
to the battery; see 8.4 Fast Charging.
WARNING! Use the boost mode for short
periods ONLY and observe the battery at all
times while boost mode is active.
• The ammeter indicates the current being applied to
the battery – the battery is charged when:
− The ammeter displays a value of near zero.
− The timer ends and the bell sounds.
• The timer dial sets the period that the current is active
when modes 4, 5 or 6 are selected.
