FEATURES
7-STAGE AUTOMATIC CHARGING (GEL, AGM, WET & CALCIUM)
Intelli-Charge incorporates the latest technology to deliver a 7-stage charge suitable for
automotive, calcium, marine and all types of deep cycle batteries (Gel and AGM). These
stages of charging ensure maximum battery life and performance are delivered with a
faster charging time and ensure a complete charge is achieved.
The 7 charge stages are:
Desulphation; Soft Start; Bulk; Absorption; Analysis; Recondition and Float.
Desulphation
The Desulphation stage is designed to break down sulphation occurring in batteries
that have been left flat for extended periods of time, returning them back to full charge.
Sulphation occurs when lead-sulphate hardens and clogs up the battery cells.
Soft Start
This is a preliminary charge process that gently introduces power to the battery,
protecting the battery and increasing battery life.
Bulk (Constant Current)
The Bulk stage reduces charging time by charging the battery at the maximum rate (constant
current) to a set voltage, at which point the battery is approximately 80% charged.
Absorption (Constant Voltage)
The absorption stage charges the battery to 100% by adjusting the charge rate allowing
the battery to absorb more power.
Equalisation (Calcium mode only)
Designed especially for calcium batteries, this stage returns calcium batteries to full
service by removing acid stratification of the electrolyte.
Analysis
The analysis mode tests the battery to ensure that it has taken the charge; if the battery
passes the test the charger will proceed to the float stage, but if the battery fails the test,
the charger will apply a recondition charge to try to return the battery to full charge.

4
Recondition
If after charging, the battery is unable to hold the charge the battery reconditioning
function is initiated automatically. This is most likely to take place on batteries that
have been deeply discharged, prior to charging. The Recondition mode will then run
for 4 hours and at the end will retest the battery. The Intelli-Charge battery charger will
perform the recondition charge up to 3 times before switching the charging cycle
to Float with an error indication.
Float
The Float stage maintains the battery at 100% charge without overcharging or damaging the
battery. This means the charger can be left connected to the battery indefinitely.
5-STAGE LITHIUM AUTOMATIC CHARGING
When the Lithium Profile is selected, Intelli-Charge utilises a very specific and tailored
5 stage charging algorithm,engineered to get the best out of today’s Lithium (LiFePO4)
batteries. From the smallest 1 Amp unit up to the largest 50 Amp offering, world class
electronics guarantee the battery receives the ultimate charge to ensure maximum life
and performance over the life of the battery.
The 5 lithium charge stages are:
Soft Start 1; Soft Start 2; Bulk Charge; Absorption and Float.

ADJUSTABLE CHARGE RATE
The charger’s output can be adjusted to suit the size of the battery for optimum
charging.
MULTI CHEMISTRY
The Multi-Chem function allows you to set the charging profile to suit each battery’s
chemistry type (Lithium, GEL, AGM, WET and Calcium). This ensures correct and
thorough charging and maximises battery performance and battery life.
POWER SUPPLY
When Power Supply mode is selected, you can safely run an appliance or load from
your battery. An appliance can also be run directly from the battery clamps if required,
for example using the charger as a memory saver when disconnecting the battery
from the vehicle.
WIRING HARNESS (IC7 ONLY)
The wiring harness allows for easy connection to vehicles that have hard to reach
batteries. Includes an inline fuse to protect the harness from accidental short circuits.
RUBBER END CAPS (IC7W ONLY)
Rubber end caps provide added durability and protection for workshop environments.
CHARGE STATUS INDICATOR
The CHARGING and FULLY CHARGED LEDs will illuminate and flash in various patterns
to indicate the different stages of charging. See below for flash patterns.

POLARITY PROTECTION
Prevents the output leads from sparking due to accidental reverse connection or short
circuit making the charger safer to use around batteries.
OVER TEMPERATURE PROTECTION
If the temperature within the charger rises too high, the charger will begin to cool down
by turning on the fan, and if the temperature continues to rise it will begin reducing the
power output. If still unsuccessful, the charger will shutdown until it cools down.
SWITCHMODE TECHNOLOGY
Using the latest technology in battery chargers, switchmode chargers convert 240VAC
power to 12VDC power using electronic components unlike traditional battery chargers
that rely on heavy transformers. This allows the charger to be lightweight and compact
without sacrificing on performance.
COOLING FAN
The charger is fitted with a thermostatically controlled fan to cool onboard electronics
and maintain charging performance. The cooling fan will engage automatically when
there is a high load on the battery or there is sufficient heat build up.
REMOTE CONTROL DISPLAY*
Control and monitor the charger’s performance from a remote control display, allowing
the charger to be flush or surface mounted out of the way and out of sight. The battery
charger and remote are synchronised for operation either locally or by remote.

thorough charging and maximizes battery performance and battery life.
1. Press the Mode button; all the lights will come on. Wait for the lights to turn off.
2. Press the Mode button repeatedly until the correct battery type is selected.
POWER SUPPLY (CONSTANT VOLTAGE OF 13.8 VOLTS)
This sets the charger in power supply mode giving a constant voltage of 13.8VDC.
This mode is best used where appliances are drawing power from the battery, for
example like a Fridge. Although the charger is designed to work with a battery
connected, it can also work without a battery.
LITHIUM (MAX VOLTAGE OF 14.2 VOLTS)
Charger will use a lithium-specific 5 stage charging algorithm.
GEL (MAX VOLTAGE OF 14.1 VOLTS)
This charge mode is designed for GEL batteries and has a maximum charge voltage
of 14.1V. Note that some GEL batteries require a higher charge voltage such as 14.4V.
The AGM mode can be used if this is required.
AGM (MAX VOLTAGE OF 14.4 VOLTS)
This charge mode is designed for AGM batteries and has a maximum charge voltage
of 14.4V.
WET (BULK AND ABSORPTION 14.7 VOLTS, RECONDITION UP TO 16 VOLTS)
This charge mode is designe d for WET batteries and has a maximum charge voltage
of 14.7V during Bulk and Absorption stages and 16.0V during the Recondition stage.
CALCIUM (BULK AND ABSORPTION 14.7 VOLTS, EQUALISATION AND
RECONDITION UP TO 16 VOLTS)
This charge mode is best suited for Calcium batteries that have been deeply discharged
and require an equalization charge to restore a full electrolyte reading. If the battery
requires a simple ‘top-up’, the WET charge mode can be used.

FREQUENTLY ASKED QUESTIONS
Q. How do I know if the battery is charged?
A. The charger’s FULLY CHARGED LED will illuminate (solid). 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. I have connected the charger properly but the ‘CHARGING LED’ 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 7 Stage chargers are
designed to charge from as little as 2.5 Volts.
If the voltage is lower than 2.5 Volts use a pair of booster cables to connect between
two batteries to provide more than 2.5 Volts to the battery being charged. The charger
can then start to charge the battery and the booster cables can be removed.
Q. Can I use the charger as a power supply
A. Yes, by selecting Power Supply mode you are able to use the charger as a power supply
to run an appliance. Ensure the appliance being run is not greater than the charger’s
output current and where possible connect the charger to a battery, and the battery
to the appliance.
The charger may also be used to connect to a vehicle while changing the battery
to maintain the vehicles computer and radio settings.
Q. Why does the charger reset when I connect a load directly to the battery
charger in Power Supply mode.
A. The charger will reset when in Power Supply mode if the load exceeds the chargers
capacity. Some appliances when turned on or first connected to the charger will cause
the charger to reset and it will re-try by slowly ramping up its output.
Q. How can I tell what stage the battery charger is in?
A. Below are the conditions that are displayed by the LEDs for each of the charge stages.

Q. What happens if my battery charger is in Desulphation mode or Soft Start
mode, but I want to start bulk charging?
A. Desulphation mode is time limited to 6 hours and Soft Start is limited to 1 hour. If you
can not wait for the battery charger to move through these stages you can select Power
Supply mode to charge the battery. After an hour of charging in Power Supply mode,
there should be sufficient charge in the battery to bypass both Desulphation and Soft
Start. Select the correct battery chemistry type to continue charging the battery. Whilst
in Power Supply mode the charger will output a full current up to 13.8V.
Q. What if I have an appliance connected to the battery whilst charging?
A. Powering an appliance while charging your battery will impact on the battery chargers
ability to accurately measure the battery’s response to the charge being applied.
The battery charger has been designed to accommodate this situation although not
recommended.
For optimum charging it is recommended to charge without any appliance load on
the battery. Power Supply mode is recommended when an appliance is connected to
a battery and is drawing power.
Q. Can I select a different battery chemistry for charging my battery?
A. Yes the battery chemistry selection can be different to your battery type if the charge
voltages match the battery manufacture’s recommendations.
Q. Why does CALCIUM mode take so long to charge?
A. To fully charge a Calcium battery, the battery requires an extra charging stage called
‘Equalization’. This consists of a constant current being fed into the battery until 16V is
reached. This rejuvenates the battery cells. This charging stage can take up to 12 hours.
Q. Why do I need a special Calcium mode?
A. Because of the different chemistry used to make a Calcium battery, a different charging
algorithm (or technique) is required. Calcium batteries are also affected when deeply
discharged or used heavily. They need to be recharged by a Calcium charger to fully
recharge the battery and to maximize the battery’s life and performance.
Q. What is a Calcium battery?
A. Calcium batteries are lead acid batteries that have had calcium added to the
lead plates, either to one plate (called Calcium Hybrid) or to both plates (called
Calcium–Calcium).
The added calcium provides a number of benefits:
i. Lower internal resistance which provides a small increase in CCA performance.
ii. The ability to withstand higher engine bay temperatures.
iii. Low self discharge rate, which increases the shelf life, typically 4 times longer
than a Lead–Lead battery.
