OWNER’S MANUAL

Model: CC6121.2

AUSTRALIAN & NEW ZEALAND STANDARD AS/NZS 60335.2.29 APPROVED

1 • Owner’s manual - Model. CC6121.2

Congratulations on purchasing your Century selectable 6 volt and 12 volt automatic battery charger,
maintainer and rejuvenator. Please take the time to carefully read and understand this manual before
using this product.

IMPORTANT SAFETY ADVICE AND WARNINGS

• The CC6121.2 is designed to charge and maintain 6V and 12V conventional lead-acid batteries only,
including:

- Sealed Maintenance Free (SMF) ooded calcium batteries.

- Absorbed Glass Mat (AGM) and maintainable ooded batteries.

- Gel electrolyte type batteries.

• Always refer to the battery manufacturers specications and recommendations if you’re unsure of your
battery charging requirements. Eg. Such as removing or not removing cell caps whilst charging, battery
type, maximum charge rate etc..

• Explosive gases may escape from the battery during charging so please ensure the battery is charged in a
well ventilated area - never in a closed room.

• This charger is designed for indoor use only and should never be exposed to water, rain, snow, liquids etc.

• Always wear eye protection when working near batteries.

• Always turn battery charger or ignition o* before disconnecting a battery.

• Do not attempt to use the charger if it has been dropped or damaged.

• Do not attempt to use the charger if the cables or plugs are damaged.

• Battery acid can cause burns. Suitable hand, eye and face protection and protective clothing must be
worn. It is highly recommended to wear PPE (Personal Protection Equipment) including safety glasses,
chemical resistant gloves and overalls.

• First Aid: For advice, contact the Poisons Information Centre in Australia (phone 13 11 26) or the National
Poisons Centre in New Zealand (phone [phone]), or contact a doctor immediately. If battery acid
enters your eyes, hold eyelids apart and ush the eye continuously with running water. Continue ushing
for at least 15 minutes or until advised to stop by poisons information centre, national poisons centre or
doctor. If battery acid contacts your skin or clothing, wash immediately with soap and water. If hair con­tact occurs, remove contaminated clothing and ush hair with soap and running water. Someone should
always be within range of your voice.

• If electrolyte is swallowed, do NOT induce vomiting – give a glass of water. Seek immediate medical
assistance.

• Never attempt to charge a damaged battery, frozen battery or non rechargeable battery.

• Never place the charger on the battery or battery on the charger.

• When working with lead-acid batteries, remove personal metal items such as rings, bracelets, necklaces,
watches and make sure you don’t short circuit the battery terminals with any type of metal tool, piece of
jewellery or other conductors as this will cause an explosion. You can wrap your spanner with insulation
tape to minimise the risk of a short circuit.

• NEVER smoke, use an open ame or create sparks near a battery or charger during charging operation as
explosive gases may cause an explosion. Flames, sparks, burning cigarettes or other ignition sources must
be kept away at all times.

• Do not disassemble the charger. Take it to a qualied and authorised person for repair.

• Acid spill response: Bund and neutralise spills with soda ash or other suitable alkali. Dispose of residue as
chemical waste or as per local requirements.

• If using a generator, you must ensure you use a surge protector to protect the charger from voltage
spikes.

• Children should be supervised to ensure that they do not play with the appliance.

• This appliance is not intended for use by persons (including children) with reduced physical, sensory or

mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety.

• The appliance should not be recharging non-rechargeable batteries.

* In some vehicles, ignition may be required to be placed in accessory mode where electronic memory
minder is present.

IMPORTANT: Never charge a 6V battery on the 12V setting as this may cause an explosion
and fire.

MAIN FEATURES

• Automatic smart battery charger & maintainer with reconditioning. Ensure the correct
battery voltage setting is selected.

• The battery charger is easy to use and requires no technical experience.

• Fully microprocessor controlled with safety timers at every stage.

• Multi Stage:

1 - Qualication - Battery condition check
2 - Battery rejuvenation (reconditioning mode)
3 - Soft start charging
4 - Bulk charging
5 - Absorption charging
6 - Battery analysis
7 - Float mode
8 - Long term maintenance pulse charge

• Battery condition analysis.

• Battery voltage retention analysis.

• Automatic diagnosis and charge: On power up, the charger will automatically diagnose the
battery condition and determine if the rejuvenation mode (reconditioning) or charge cycle is
required.

• Patented battery rejuvenation (reconditioning) technology: The charger has a unique
and patented rejuvenation feature which uses high voltage equalising and peak pulse re­conditioning to repair sulphated batteries. This feature is fully automatic and depends on the
internal impedance of the battery. It also depends on whether the battery is still connected in
the vehicle.

• Ultra low power consumption (ECO Mode)

• Pulse charge for long term maintenance.

• Can be left on 24/7 to ensure your battery is always maintained and fully charged: The
battery charger can be left permanently connected all year round. The intelligent charger
will monitor the battery voltage and will maintain it at peak performance with a special pulse
charge during long term maintenance. Please note that even if the battery charger incorpo­rates this feature, Century Batteries does not recommend leaving the battery charger

connected 24/7.

• Short circuit and reverse polarity protection.

• Heavy-duty and corrosion-resistant output connectors.

• Crocodile clips / Ring Terminals: It comes with a quick connect y lead and heavy duty, fully
insulated crocodile clip harness and ring terminal harness.

• Selectable 6 volt and 12 volt output.

TEMPERATURE & SAFETY PROTECTION:

• INTERNAL OVERHEAT PROTECTION: The charger has a built-in overheat and an overload

electronic circuit. This protects the charger from being damaged if overheated or overloaded
and will automatically decrease the charging current. Once the unit’s internal temperature
decreases to a safe level, the charger will resume normal charging.

• SAFETY TIMER PROTECTION: The charger has safety timers for every stage. If the battery
voltage doesn’t reach a certain voltage within a certain time, the unit will stop charging as it
is highly likely that you are attempting to charge a severely discharged or heavily sulphated
battery. If any of the stages times out, the charger will immediately stop charging in order to
protect the battery. This will be indicated with the fault LED ON.

• REVERSE POLARITY: The charger has reverse polarity protection. If the charger output leads
are connected reverse polarity, the fault LED will come on and the charger will be disabled.
Simply unplug the charger from AC power and then connect the output leads to the correct
polarity.

• SHORT CIRCUIT PROTECTION: The charger will automatically turn o if the output leads are
short circuited and the fault LED will come on. This prevents the charger from being damaged
if the positive and negative crocodile clips or the optional ring terminals accidentally touch each
other while the charger is turned on.

• ECO MODE: This Century battery charger has a built in ultra low power consumption circuit.
If AC power is connected and the battery is disconnected, after 10 seconds the charger will
automatically go into an ECO mode. During this mode the power drawn is less than 0.36W
which totals 0.01kWh per day power consumption. If AC power is connected and the battery
is connected, once the battery is fully charged and during the long term maintenance stage,
the total power consumption is around 0.03kWh per day.

The Power LED will flash RED to indicate ECO mode.

BATTERY TYPES & CAPACITY:

• Suits 6V and 12V conventional lead acid batteries: All SMF [Calcium], AGM/Flooded & Gel.
