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 sulfate hardens and clogs up the battery cells.

Soft Start
A preliminary charge process that reduces the initial current in 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.

Analyze
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.

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

Featuring the latest technology in battery chargers, switch-mode chargers convert 240V AC power to 12V DC power using electronic components, unlike traditional battery chargers that rely on heavy transformers. This allows the charger to be lightweight 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 the battery charger connects with a nonbattery load, it will go into a 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.
COOLING FAN
The charger is fitted with a fan to cool onboard electronics and maintain charging performance.

CHARGING INSTRUCTIONS

Settings are made by pressing the MODE button (Press/Hold). After about two seconds the charger activates the selected program. The selected program will automatically default to the AGM Mode next time the charger is connected
STEP 1 – CHECK THE ELECTROLYTE LEVEL
Please ensure to check the electrolyte level prior to charging the battery by removing the vent caps (not required on sealed & maintenance-free batteries.The electrolyte level should be 6mm (1/4″) above the battery’s plates. If low, use distilled water to top up to the correct level and refit the vent caps.
STEP 2A – CONNECTING TO BATTERY OUT OF VEHICLE
Connect the RED Output Lead (Battery Clip from the charger to the Positive (+) Battery Terminal) and ensure a good connection is made.
Connect the BLACK Output lead (Battery Clip from the charger to the Negative (-) Battery Terminal) and ensure a good connection is made.
Alternatively if connecting via the Chargers Output Plug, make sure the polarity of the external plug is correct before connecting.

STEP 2B – CONNECTING TO THE BATTERY IN THE VEHICLE
Before connecting, determine if the vehicle is Negative (-) or Positive (+) Earthed.
Negative earthed vehicles are most common and use the chassis as an Earth by connecting the Battery Negative Terminal to a conductive chassis point.
The purpose of connecting the charger through the chassis is to eliminate any power spikes going through the vehicle’s sensitive electrical system.
If you are unsure, please seek advice from a qualified person before connecting.

NEGATIVE EARTHED CONNECTION (Most Vehicles)

Connect the RED Output Lead (Battery Clip) from the charger to the Positive (+) Battery Terminal and ensure a good connection is made.
Connect the BLACK Output Lead (Battery Clip) from the charger to a clean conductor point on the vehicle’s chassis away from any fuel lines or moving parts.

POSITIVE EARTHED CONNECTION

Connect the BLACK Output Lead (Battery Clip) from the charger to the Negative (-) Battery Terminal and ensure a good connection is made.
Connect the RED Output Lead (Battery Clip) from the charger to a clean conductor point on the vehicle’s chassis away from any fuel lines or moving parts.

CHASSIS EARTHING (Not Essential)

The chassis earthing terminal should be connected to an earthing point which will be depending on where the battery charger is installed. In a vehicle, connect the chassis ground terminal to the chassis of the vehicle. In a boat, connect to the boat’s grounding systems. In a fixed location, connect to an earth stake. This connection is not essential but may increase efficiency.

STEP 3 – CONNECT TO 220-240V AC MAINS POWER
Connect the battery charger to a certified 220-240V AC mains power socket and turn on the mains power.

STEP 4 – CHARGING PROCESS
During the charging process, the ‘Charging’ and ‘Stage’ LEDs will flash various patterns. This is normal and indicates the various charging stages. Refer to “How do I know what stage the battery charger is in” in the FAQ section, page 18.
When the ‘Stage’ LED remains on (this is known as the Float Stage) the charger can be left connected to the battery indefinitely without overcharging.
Alternatively, the battery can be disconnected at this point as it is fully charged.
If the ‘Power On’ LED is flashing, there is a fault; refer to the “Fault Codes” explanation on page 17 of this manual.

STEP 5 DISCONNECTING THE CHARGER FROM BATTERY
Ensure the 220-240V AC mains switch is turned off and the charger is disconnected from the 220-240V AC mains power.

MOUNTING INSTRUCTIONS

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 well-ventilated 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.

PERMANENT WIRING TO BATTERY

If required, It is possible to hard wire the DC charging Output Leads to the battery for permanent installations.
You will need an Adaptor Lead with Ring Terminals, Fuse, Fuse Holder, and a suitable Plug to attach to the current Charger Plug.
Alternatively, if you would like to install this yourself please follow the steps below:

1. Cut off the supplied battery clips; ensure you leave a sufficient cable to reach the battery terminals. (DO NOT extend the battery charger DC output cables, as the added voltage drop will cause incorrect charging).
2. Fit a ring terminal to the BLACK Negative (-) wire.
3. Connect the In-line fuse to the RED Positive (+) wire.
4. Connect a ring terminal to the other end of the in-line fuse.
5. Connect the RED Output Lead (with in-line fuse and ring terminal) to the Positive (+) battery post.
6. Connect the BLACK lead (with ring terminal) to the Negative (-) Battery Terminal.
7. Fit the correctly rated fuse. (Recommended: Double the charger’s current rating)

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 battery fully charged.
Ensure any modification to the 220-240V AC mains lead is carried out by a qualified person and that connection to the mains supply is in accordance with the National wiring rules.

FREQUENTLY ASKED QUESTIONS

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) under load, the 8-Stage chargers are designed to charge from as little as 7.0 Volts (12V 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:

| 1 Desulphation| 2 Soft Start| 3 Bulk| 4 Absorption| 5 Analyze| 6 Recondition| 7 Float| 8 Maintain
---|---|---|---|---|---|---|---|---
Stage| | | | | | | |

Q. What if I have a question that has not been answered?
A. Please contact the supplier for any further questions or advice.
