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.
1. DESULPHATION
Rejuvenates sulphated
batteries with a high
frequency pulse.
2. SOFT START
Increases battery life
by gently starting to
charge the battery.
3. BULK CHARGE
Reduces charging
time by delivering
maximum charge to
set voltage.
4. ABSORPTION
Ensures a full
charge to the
battery without
overcharging.
EQUALISATION
(Calcium mode only)
Returns a full
hydrometer reading
to calcium batteries
by removing acid
stratification.
5. ANALYSIS
Tests the battery to
ensure fully charged.
6. RECONDITION
Restores battery
health to deeply
discharged batteries
by equalising
the cells.
7. FLOAT
Float charge
maintains the
battery at 100%
charge.
VOLTAGE
CURRENT
(AMPS)
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.

BATTERY CHEMISTRY SELECTION
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. The following
section describes the charge profiles for each chemistry type.
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 a Fridge.
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 designed 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 equalisation charge to restore a full electrolyte reading. If the battery
requires a simple ‘top-up’, the WET charge mode can be used.

13
STEP 2C – PERMANENT HARD WIRING
It is possible to hardwire the DC charging leads to the battery for permanent installations.
The DC leads are pre-wired with cable lugs to make this process easier.
It is recommended to fit a circuit breaker or inline fuse with the following ratings. (See below)
IC25, IC25W, IC25RV = 30 Amp
IC35 = 50 Amp
IC50 = 100 Amp
IC8-24 = 12 Amp
Connection:
1. Unscrew and remove the battery clips from the DC leads using a 4mm allen key.
Note: These battery chargers include sensor wires that run parallel to both the
positive and the negative DC leads. This allows for accurate voltage measurements
to be taken directly from the battery. It is strongly recommended not to cut the DC
leads during installation. However if the DC leads are cut, ensure that the sensor
wires are included in both positive and negative connections.
2. Connect a circuit breaker or inline fuse to the RED Positive (+) lead (include sensor
wire if DC lead has been cut).
3. Connect a short cable to the other end of the circuit breaker or inline fuse & connect
to the Positive (+) battery post.
4. Connect the cable lug fitted to the BLACK lead to the Negative (-) battery post
(include sensor wire if DC lead has been cut).
5. Fit the correctly rated fuse (inline fuse applications only).
If the charger is used in a Permanent/Hard Wired application and the vehicle will not be
used for some time, it is best to leave the charger connected to mains power (turned ‘On’)
so that it can maintain the battery fully charged.
Ensure any modification to the 240V mains lead is carried out by a qualified person
and that connection to supply mains is in accordance with National wiring rules.
