INSTRUCTION MANUAL
WARNING: BEFORE USING THE BATTERY CHARGER READ
THE INSTRUCTION MANUAL CAREFULLY.
1. GENERAL SAFETY RULES WHEN USING THIS BATTERY
CHARGER
- During the charge the battery produces explosive
gases, avoid the formation of flames and sparkes.
DO NOT SMOKE.
- Position the batteries to be charged in a well-ventilated
place.
- Inexperience and untrained people should be
properly instructed before using the appliance.
- This appliance can be used by children aged from 8
years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience
and knowledge if they have been given supervision or
instruction concerning use of the appliance in a safe
way and understand the hazards involved.
- Children shall not play with the appliance.
- Cleaning and user maintenance shall not be made by
children without supervision.
- Disconnect the mains cable before connecting to or
disconnecting the charging cables from the battery.
- Do not connect or disconnect the clamps to or from the
battery with the battery charger operating.
- Never use the battery charger inside the car or in the
bonnet.
- Substitute the mains cable only with an original one.
- If the supply cord is damaged, it must be replaced by
the manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
- Do not use the battery charger to charge batteries which
are not rechargeable.
- Make sure the available power supply voltage corresponds
to that shown on the battery charger rating plate.
- To avoid damaging the vehicle's electronics, read, keep
and take very careful note of the information supplied by
the vehicle manufacturer, when using the battery charger
either for charging or starting; the same applies to the
instructions supplied by the battery manufacturer.
- This battery charger has components such as switches
and relays which can cause arcs or sparks. Therefore when
using it in a garage or in a similar place set the battery
charger in a suitable case.
- Repair or maintenance of the inside of the battery charger
can be executed only by skilled technicians.
- WARNING: ALWAYS DISCONNECT THE POWER SUPPLY
CABLE FROM THE MAINS BEFORE CARRYING OUT ANY
SIMPLE MAINTENANCE OPERATION ON THE BATTERY
CHARGER.
2. INTRODUCTION AND GENERAL DESCRIPTION
- This battery charger can be used to charge free electrolyte
lead acid batteries used on petrol and diesel engine
vehicles, motor cycles, boats etc. and is suitable for
charging sealed batteries.
- Accumulators rechargeable in accordance to the output
voltage available: 6V / 3 cells, 12V / 6 cells, 24V / 12 cells.
- This model is a battery charger with a 230V 50/60Hz
single phase power supply, with electronically-controlled
constant current and voltage.
The charge current and voltage supplied by the appliance

(EN)

follow the IU charge curve.
- Standard accessories:
With this appliance it is possible to connect different types
of output cables for battery charging:
- cables fitted with clamps (fig. B-2);
- cables fitted with eyelets (fig. B-1);
3. DESCRIPTION OF THE BATTERY CHARGERS
Control devices, adjustment and indicator lights.
- Selecting the charge current:
The key shown in fig. A-1 can be used to set the charge
current at:
DEFENDER 20
2A ( ), 4A
The LED's shown in fig. A-2 will light up to correspond with
the symbol and the selected charge current.
- Indicators (fig. A-3):
- Red LED:
Reverse polarity, Danger!!!
Invert the charge clamp connections!
- Yellow LED:
Charging in progress.
Green LED:
-
End of charging.
- The key shown in fig. A-5 is used to set the charging mode
and the type of battery to be charged. In CHARGE mode
the battery-charger works in the usual way, charging the
battery at a constant current during the initial phase and
at a constant voltage during the final phase. CHARGE
mode, which is less efficient than PULSE-TRONIC mode,
is recommended when you do not know the construction
technology or the type of the battery to be charged.
In PULSE-TRONIC mode, which is more sophisticated than
CHARGE mode, the button is used to change and select
the end-of-charging voltage threshold. PULSE operation
combined with TRONIC technology guarantees an
optimum charge status for the battery and ensures it will
keep its charge. The possible types of battery that may be
selected are (fig. A-4):
WET: lead-acid batteries with liquid electrolyte.
GEL/AGM: sealed lead-acid batteries, with solid electrolyte
(GEL), and sealed lead-acid batteries in which the
electrolyte is held by absorbent material.
4. INSTALLATION
POSITIONING THE BATTERY CHARGER
- While the battery charger is in operation make sure it is in
a stable position.
- Do not lift the battery charger using the power supply
cable or the charge cable.
CONNECTION TO POWER
- The battery charger should be connected only and
exclusively to a power source with the neutral lead
connected to earth.
Check that the net voltage is the same as the voltage of the
equipment.
- Check that the power supply is protected by systems as
fuses or automatic switches, sufficient to support the
maximum absorption of welding.
- If you put an extension to the primary cable, the diameter
must be the same, never inferior.
- The connection to the power has to be made using the
cable.
5. OPERATION
BEFORE CHARGING
NB: Before charging check that the capacity of the
battery (Ah) which is to be charged, is not inferior to that
reported on the data table. (C min).
