FEATURES
Automatic Charging
When in automatic mode the charger will stop charging the battery when the battery is fully charged.
You can leave the charger connected to the battery without risk of overcharging. Once the battery is full,
the battery charger will automatically start to maintain the battery. The charger monitors the battery voltage
and continues to top up the battery, keeping it fully charged and ready for use.
Manual Charging
The charger in this mode will continue to charge the battery until the timer finishes or is turned off and
requires the user to monitor the charging battery. When used by experienced users it can deliver an
equalization charge to balance the voltage in the battery’s cells.
LED Indication
OVER OAD (Red ED Flashing): The ED will flash when the transformer or the current regulators (SCR’s)
have got too hot
POWER ON (Red ED ON): The ED comes on when connected to power and the charger is switched on
POWER ON (Red ED Flashing): Indicates that the battery clamps have been connected in reverse polarity
Charging (Orange ED on): The ED comes on indicating charging
Fully charged (Green ED on): The ED comes on when the battery is charged
VO T (Red ED ON): The ED indicates that Voltage is being displayed
AMP (Red ED ON): The ED indicates that Amps or current is being displayed
LED Voltage/Amp Display
The charger has a VO T and AMP meter built in. When the charger is initially powered up the display will
show voltage. When the VO T / AMP button is pressed the Amps will be displayed, press the button again
the display will go back to Volts. When Volts is displayed this indicates the state of charge of the battery,
when Amps is displayed this indicates how much charge is being accepted by the battery.
verride Button
The battery charger measures the battery voltage at the clamps to determine if the battery is correctly
connected. A reading above 3V will activate the battery charger. In some instances where the battery is
extremely flat, it is possible to have correct connection and the battery to be below the 3V limit. In this
instance check the battery leads to ensure they are connected correctly and press the OVERRIDE button
to activate the battery charger.
Multi Voltage
Suitable for charging 6V, 12V & 24V batteries.

Engine Start
If you need to get going and the battery is flat then the engine start will help you out. Connect
the charger to the battery, set it to engine start mode for 5 minutes, then start your engine.
0–14 Hour timer
Automatically turns the battery charger off after a set time. The timer has 1 hour intervals with
a maximum of 14 hours. This switch can also be set to permanently ON.
Toroidal Transformer
Using the latest technology in transformer design, toroidal transformers don’t use a solid iron
core (like traditional transformers) making them lighter and more compact. They deliver more
power than a traditional transformer charger of the same size.
Protection features
The charger is fitted with the following protection features:
1. Reverse polarity protection – Where the battery leads are connected incorrectly the charger will
flash the power ED and not charge the battery.
2. Short circuit protection – There is no voltage at the leads until the battery clamps are connected
to the battery.
3. Overload protection – To prevent damage to the electronics the charger will switch off when
overloaded, it will automatically reset when safe. The overload ED will flash in these times.

CALCIUM BATTERY CHARGING OR EQUALIZATION CHARGE
Calcium batteries are becoming more commonly sold as they have a longer shelf life (4 times longer than
a lead antimony battery), they also have a better ability to withstand higher engine bay temperatures, and
have increased cranking output. They also require a different charging technique when left flat or when
deeply discharged.
STEP 1 to 3
Follow STEPS 1 to 3 of the Charging instructions of this booklet. Ensure that the battery is removed from
the vehicle to prevent the batteries electrolyte from spilling over and damaging the car or engine bay.
STEP 4 – SET BATTERY V LTAGE
Set switch to either 6V or 12V depending on what battery voltage you are charging. For 24V vehicles the

FREQUENTLY ASKED QUESTIONS
Q. How do I know if the battery is charged?
A. The battery charger’s GREEN ‘FU Y CHARGED’ ED will illuminate to indicate when the battery is fully
charged. Alternatively use a Battery Hydrometer (Projecta Part No. BH100). A reading of 1.250 or more
in each cell indicates a fully charged battery.
Q. Why does the battery charger have two ratings?
A. Battery chargers for automotive use have traditionally been given an RMS rating in the past. This rating
is now used as an industry reference only. Australian Standards now require all battery chargers to be rated
at the charger’s continuous output at a nominated voltage, we express this as mA (milliamps) rather than
A (Amps) to avoid confusion.
Q. Why does the ‘FULLY CHARGED’ LED come on straight away?
A. There are four possible reasons why the ‘FU Y CHARGED’ ED may come on straight away.
1. The battery is fully charged.
2. The battery has taken a surface charge.
3. The battery has a faulty cell.
4. The BATTERY VO TAGE setting on the charger is set lower than the battery voltage.
Q. What is Surface Charge?
A. Batteries unused or left flat for some time build up a resistance to being recharged. When the charger is
first connected, these batteries will take a surface charge, and the ‘FU Y CHARGED’ ED will illuminate
within a short while. The battery however is not fully charged, the charger is voltage sensitive and cannot
differentiate between a surface charge and a fully charged battery. After a few hours the battery may start
to accept some charge but most batteries with this condition will not recover.
Q. What is a Faulty Cell?
A. 12 Volt batteries contain 6 cells and one faulty cell is enough to ruin your battery. If after eight hours of
charging your battery is still flat, you should test the cells using a hydrometer. If one reading is lower than
the rest it indicates a faulty cell. It is pointless to continue charging, as the battery needs replacing.
Q. I have connected the charger properly but the ‘ range’ charging light does not come on?
A. In some cases batteries can be flattened to the point where they have very little or no Voltage. This can
occur if a small amount of power is used for a long time, for example a map reading light is left on for a
week or more. Projecta automatic chargers are designed to charge from as little as 3 Volts. If the voltage
is lower than 3.0V press the override button to start the charger.
HDBC20 I structio Ma ual NEW_Layout 1 28/07/11 4:33 PM Page 12

Q. Can I use the charger as a power supply?
A. Projecta automatic chargers are designed to only supply power to the battery clips when they are correctly
connected to a battery, this is to prevent sparks or damage to the charger or battery if connected incorrectly by
mistake. This safety feature prevents the charger from being used as a ‘Power Supply’. No Voltage will be
present at the clips.
Q. In maintenance mode why does the current go high then low again?
A. While in maintenance mode it is normal for the current to go high and then low. The charger is maintaining the
battery voltage between the Cut-In and Cut-Out voltages. The pulses of power are topping up the battery to
maintain it fully charged.

HDBC20 I structio Ma ual NEW_Layout 1 28/07/11 4:33 PM Page 13

Q. What are Volts and Amps?
VO TS
The term voltage refers to the electrical force or electric potential to do work between two terminals or a good
analogy is water pressure in a pipe. For example a battery has 12 Volts between the positive and negative
terminals, or a 6 Volt battery has 6 Volts between the positive and negative terminals.
AMPS
The term AMPS is the unit of measure used for current. Which can be described as the flow of electric charge in
a circuit. Again if you use the water analogy this would refer to how much water is flowing through the pipe.
For example if the current is reading 12 Amps then this is the amount of energy going into the battery.
Q. How does a typical battery charge?
A. A typical flat battery has a low internal resistance, when first connected to a charger the battery will accept a
high current. As the battery slowly charges, the voltage and internal resistance will rise causing the battery to
accept less and less current.
