Instructions

For all 12 volt automotive battery types: lead-acid, AGM (absorbed glass mat) Gel
and deep cycle.

This charger initiates an 8-stage charging cycle which charges and maintains
the battery. Additionally there is a boost mode for battery rescue, and a steady
12v supply mode. The charger can also be used to test the battery without
connecting to a 240v AC supply. It features overload, short circuit and polarity
reversal protection.

Includes a ‘snow’ mode for charging in temperatures below 0ºC

Note: this is for AGM absorbed glass mat batteries only - never attempt to charge
a battery with frozen electrolyte.

The charger is supplied with three methods of connection:
Insulated battery clamps.
Eyelet connectors for motorcycles.
Onboard 12v connector.

1. Soft Start: Tests if the battery can accept charge; charging will commence if battery is
okay.

2. Desulphation: Pulsing current removes sulphates from the battery plates and restores
battery efficiency and capacity.

3. Bulk Charge: Charges with maximum set current until approximately 80% of capacity.

4. Absorption: Charging current drops off and brings battery to 100% charge.

5. After-Charge: For a limited period the voltage increases as the current drops down; the

higher voltage starts gassing and thus mixing of the electrolyte which is beneficial for
battery capacity and expected life.

6. Analysis: Tests if battery can maintain charge (self-discharge): if battery voltage drops
below 11.6v within 10 minutes, battery is faulty.

7. Maintenance: Keeps battery at 100% capacity without overcharging.

8. Cycle Recharge: A continuation of the Maintenance mode that monitors battery voltage

and will gently pulse current and increase voltage.

The 8-stage Charging Works as Follows

For deeply discharged batteries, in ‘boost’ mode, the charger follows the same 8-stage
charging sequence but stage 1 (Soft Start) is replaced by a ‘rescue’ stage that pulses both
voltage and current to mix the electrolyte which assists the subsequent Desulphation stage.

This rescue stage can last for up to two hours - if the battery can be returned to service the
charger will enter charge mode; if not, the error Indicator (fault light) will illuminate.

Boost Mode (Battery Rescue):

The charger can be used as a battery tester, there is no need to connect to an 240v AC
power supply. Connect the charger to the battery terminals, noting positive and negative
identification. The LED’s will display the state of charge of the battery: Full (Green LED),
Medium (Yellow LED), Low (Yellow LED), Discharged/Empty (Red LED).

Note: if the LED’s flash, then the battery is deeply discharged. Charging can be attempted
using the Boost Mode (battery rescue).

1. Identify the polarity of the battery terminals
(if not clearly indicated, the positive terminal
or post is normally larger than the negative).

2. Connect the positive (red) clamp to the
positive battery terminal first. Some modern
cars have a remote positive terminal located
away from the battery. Use this remote
terminal for the charging connector.

3. Then connect the negative (black) clamp to
the car chassis or engine block as far from
the battery as the leads will allow. Note: DO
NOT connect the clamp to fuel lines or sheet
metal body parts; connect to a heavy gauge metal part of the chassis or engine block.

4. Then connect battery clamp lead connector to the corresponding connector on the
charger lead.

Cars and Light Commercials

1. Identify the polarity of the battery terminals.

2. Choose the ‘motorcycle eyelet’ set of
connector leads; extract the eyelets
from the insulated covers and fit to the
motorcycle battery, remembering to fit the
positive connector first.

3. Then connect battery eyelet lead connector
to the corresponding connector on the
charger lead.

4. The ‘motorcycle eyelet’ set of connector
leads is designed for permanent
connection to the motorcycle; the leads
are disconnected from the charger when the motorcycle is to be used. The lead set
is supplied with a splash-proof cover which is placed snugly over the charger-end
connector when not in use.

5. Care must be taken with the routing of the connector leads when replacing the seat |
battery cover so that the leads are not pinched or squeezed. Leads must not be able
to interfere with the chain, wheels, etc. Make sure the eyelet insulating covers are
completely covering the eyelets.

• The battery is damaged | cannot accept charge.

• Operation or setting fault.

• In ‘Supply Mode’ the circuit is overloaded.

When ‘Fault’ LED has illuminated, disconnect the connectors, including the 240v AC supply
Identify reason for fault and leave for a couple of minutes before reconnecting.

Notes:

• If disconnecting main battery terminals (to remove battery from vehicle for example)
check you have codes for audio, security systems, etc.

• If removing battery from vehicle to charge it, make sure to remove the earth (ground)
terminal first. Vehicle ignition and all accessories must be turned off to avoid sparks when
removing terminals.

Warning:

• Working near a lead-acid battery is dangerous - a battery generates explosive gases
during normal operation. These gases increase when the battery is being charged.

• Ensure the work area is well ventilated.

• Make sure that there is no possibility of these gases being ignited. There must be no
naked flames, cigarettes, flame heaters, blowtorches, etc, near the battery or work area.

• The gases can be ignited by a stray spark - disconnect the charger from the mains before
disconnecting the leads from the battery.

• You must wear approved safety eye protection when connecting or disconnecting battery
| battery charger leads.

• Avoid touching your eyes while working with batteries.

Safety Notes:

• Place charger as far away from the battery being charged as the charger cables will permit.

• When working with or near a lead-acid battery make sure there is another person close
enough to come to your aid if necessary.

• If battery acid contacts skin or clothing, wash immediately with soap and plenty of water.

• If acid enters an eye, immediately flush eye with cool, clean water for at least 15 minutes
and seek medical attention.

• When working with or near a lead-acid battery make sure to remove personal metal items
such as watch straps, rings, bracelets, necklaces, etc. A short across the battery terminal
from one of the above could cause severe burns.

• Never allow the charger clamps to touch each other or to contact a piece of metal that
could bridge them.

It is the operator’s responsibility to comply with the following:

• Inspect all power supply leads, plugs and all electrical connections for wear and/or damage.

• Before use, inspect the insulation on the charger cable and check the charger and plug
before connecting to the mains supply.

• Also regularly inspect power supply sockets, extension leads and connectors.

• Ensure that the mains voltage marked on the charger is the same as the electrical power
supply to be used.

• Do not carry the charger by its power lead.

• Do not pull the power plug from the socket by the power lead.

• Extension lead reels: when a cable extension lead reel is used it should be fully unwound
before connection. We recommend the cable reel has an RCD fitted. Be sure that the
capacity of the cable reel is suitable for the product.

If in any doubt about electrical safety, consult a qualified electrician.
