8-STAGE AUTOMATIC CHARGING
This is a fully automatic battery charger featuring 8 charging stages
Automatic charging is proven to provide your battery with an optimal charge and
maintenance sequence that will also protect your battery from being overcharged.
This allows you to leave the charger connected to the battery indefinitely if required.
8-stage charging is a very accurate and comprehensive charging process that
will result in a better battery performance with a longer life expectancy. This is
evident when comparing to the use of more traditional chargers.
8-stage chargers are suitable for most battery types including WET, Calcium,
Maintenance Free, AGM, and GEL batteries. They may also help restore drained
and sulphated batteries.

Desulphation
The Desulphation stage is designed to break down sulphation that occurs in batteries that have been
left discharged for extended periods of time, this process assists in revitalizing the battery.
Sulphation occurs when lead-sulphate hardens and clogs up the battery cells.
Soft Start
A preliminary charge process that reduces the initial current into the battery. This protects the battery
from any high start up current from the charger and increases battery life and performance.
Bulk (Maximum Current)
Chargers the battery with the rated maximum output current until approximately 80% capacity. This
stage continues until the battery's terminal voltage has risen above the set limit (depending on
battery type). If the terminal voltage has not reached the set voltage limit within the pre-set time, the
charger switches to fault mode (Stage 3 LED solid) and discontinues the charging process. If so, the
battery is faulty or its capacity is too large.
Absorption (Constant Voltage)
This stage ensures the battery reaches a fully charged state by gradually reducing the current and
maintaining a constant voltage until the battery is 100% charged.
Analyse
An automatic battery test is conducted immediately after the absorption stage. This test monitors the
battery voltage for 90 seconds to determine if the charge was successful.
◆ 12V charger: If the voltage is below 13.2 volts (fail), the charger will initiate the Recondition stage.
◆ 12V charger: If the voltage is above13.2 volts (pass), the charger will proceed to the Float Stage.
◆ 24V charger: If the voltage is below 26.4 volts (fail), the charger will initiate the Recondition stage.
◆ 24V charger: If the voltage is above 26.4 volts (pass), the charger will proceed to the Float Stage.
Recondition
This stage is automatically introduced if the battery is unable to hold a charge after the Analysis
Stage. The Recondition Stage can recover batteries from a deeply discharged state, rejuvenating the
output capacity and extending the battery life.
The Recondition stage will run for 4 hours and at the end will conduct a test to determine if the
battery is now holding charge. If the battery fails this test the charger will display a fault.
Float
The Float Stage maintains the fully charged state without overcharging or damaging the battery. This
means the charger can be left connected to the battery indefinitely. The battery is fully charged and
can be disconnected at this stage.
Maintain
Designed to maintain the battery at 95-100% capacity over extended periods of time. The charger
monitors the battery voltage and gives a Maintain when necessary to remove plate sulphation and
keep the battery fully charged. This Maintain cycle is repeated infinitely over a 10 day period if left
connected. If the terminal voltage drops below the set level or is disconnected, the charger
automatically goes back to the beginning of the charging cycle.
SWITCHMODE TECHNOLOGY
3
Featuring the latest technology in battery chargers, switch mode chargers convert 240V AC power to
12V/24V DC power using electronic components unlike traditional battery chargers that rely on
heavy transformers. This allows the charger to be light weight and compact without sacrificing
performance.

PROTECTIVE FEATURES
POLARITY PROTECTION
Prevents the output leads from sparking due to accidental reverse connection or short
circuit, making the charger safer to use around batteries.
OUTPUT SHORT PROTECTION
Short circuit connection of the clips: Check clips are not touching each other OR
Check the clips are correctly connected to the battery.
NON BATTERY LINK PROTECTION
If battery charger connects with a non battery load, it will go into protection state.
DISCONNECT PROTECTION
The charger has entered the energy save mode. This happens if the charger is not
connected to the battery within 2 minutes.
OVER VOLTAGE PROTECTION
The 12V charger will automatically supply protection if the voltage is higher than 17.5V. The
24V charger will automatically supply protection if the voltage is higher than 35V.
OVER TEMPERATURE PROTECTION
This occurs if the internal temperature is above 65OC +/-5 OC
COOLING FAN
The charger is fitted with a thermostatically controlled fan to cool on-board 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.

MOUNTING INSTRUCTIONS
15
This 8-stage charger is designed for indoor use only and not outdoor conditions
(rain and moisture). Ensure that both the charger and battery are in a wellventilated area during charging.
If permanently fixed, the charger should be mounted to a suitable vertical or
horizontal panel, with at least 10cm clearance from the end plates to provide
adequate ventilation for the cooling fan.
The battery charger is molded with end plates that include a mounting flange
for easy mounting.

If the charger is used in a Permanent / Hard Wired application and the vehicle
will not be used for extended periods of time, it is best to leave the charger
connected to mains power (turned 'On') so that it can maintain and keep the
the battery fully charged.
Ensure any modification to the 220-240V AC mains lead is carried out
by a qualified person and that connection to mains supply is in accordance
with the National wiring rules.

FREQUENTLY ASKED QUESTIONS
19
Q. How do I know if the battery is charged?
A. The charger's 'Charged' and/or 'Maintain' LED (Stage 7/8) will be illuminated (solid). Alternatively
use a Battery Hydrometer (if caps are removable). A reading of 1.250 or more in each cell indicates a
fully charged battery.
Q. I have connected the charger properly but the 'STAGE LED'
does not come on?
A. In some cases, batteries can be discharged to the point where they have very little or no voltage
(Not recommended and may void warranty). This can occur if a small amount of power is used for a
long time, for example: An interior light is left on for an extended period of time or an electrical
appliance without a 'voltage cut-out' is unknowingly connected.
Q. What minimum voltage will the charger need to sense?
A. Although a battery is not designed to be discharged below 10.5 Volts (12 Volt System) and 21
Volts (24 Volt System) under load, the 8-Stage chargers are designed to charge from as little as 7.0
Volts (12V charger) and 14.0 Volts (24V charger). If the battery voltage is lower than this, use a pair of
booster cables to connect an external battery with the same voltage in parallel. This should provide
more than the required 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. 8-Stage chargers are designed to supply power to the battery clips Only, when they are connected
correctly to a battery. This is to prevent sparks during connection to the battery or 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 until connected to the battery.
Q. How do I know what stage the battery charger is in?
A. Below are the conditions that are displayed by the 'Stage' LED for each of the charge stages:

SAFETY
21
The charger is designed for charging 12V or 24V Lead-Acid, AGM, Gel and
Calcium Batteries. Do not use the charger for any other purpose.
◆ Check the charger cables prior to use. Ensure that no cracks have occurred in the cables or in
the battery clips. A charger with damaged cables or clips must not be used. A damage cable or
clip must be replaced by a professional representative.
◆ Never charge a damaged battery.
◆ Never charge a frozen battery.
◆ Never place the charger on top of the battery when charging.
◆ Always allow for adequate ventilation during charging.
◆ Avoid covering the charger.
◆ A battery being charged could emit explosive gases. Prevent sparks close to the battery. When
batteries are reaching the end of their life-cycle internal sparks may occur.
◆ All batteries fail sooner or later. A battery that fails during charging is normally taken care of by
the charger's advanced control, but some rare errors in the battery could still exist. Don't leave any
battery during charging unattended for an extended period of time.
◆ Ensure that the cabling is not obstructed or come into contact with hot surfaces or sharp edges.
◆ Battery acid is corrosive. Rinse immediately with water if acid comes into contact with skin or
eyes, seek immediate medical advice.
◆ Batteries consume water during use and charging. For batteries where water can be added, the
water level should be checked regularly. If the water level is low, add distilled water.
◆ This appliance is not designed for use by children or people who cannot read or understand the
manual unless they are under the supervision of a responsible person to ensure that they can use
the battery charger safely. Store and use the battery charger out of the reach of children, and
ensure that children cannot play with the charger.
◆ Connection to the mains supply must be in accordance with the national regulations for electrical
installations.
