Congratulations on purchasing an Oz Charge fully automatic 12 Volt 15 Amp DC/DC battery charger.
Please take the time to carefully read and understand this manual before using this product.
IMPORTANT SAFETY ADVICE AND WARNINGS
• The charger is designed to charge and maintain 12V conventional lead-acid batteries only.
(VRLA), AGM, CALCIUM, GEL & WET.
• Always refer to the battery manufacturers specifications and recommendations if you’re unsure of your battery charging requirements. Explosive gases may escape from the battery during charging so please ensure the battery is charged in a well ventilated area.
• This charger is designed for indoor use only and should never be exposed to water, rain, snow, liquids etc.
• Do not attempt to use the charger if it has been dropped or damaged.
• Do not attempt to use the charger if the input or output cables or plugs are damaged.
• If battery acid contacts your skin or clothing, wash immediately with soap and water. If acid enters your eye, immediately flush the eye with running cold water for at least 10 minutes and seek medical attention. Someone should always be within range of your voice.
• 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 or piece of jewellery 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 flame or create sparks near a battery or charger during charging operation as this may cause an explosion and explosive gases.
• Do not disassemble the charger. Take it to a qualified and authorised person for repair.
• The charger must not be used or played with by infirm persons or children. Also keep it away from any pets.

WIRING DETAILS:
To ensure the best performance we recommend installing the DC DC Charger as close as possible to the auxiliary battery that is being charged (Output). Should be in a cool dry area.
The Input connections are made to the vehicles battery / alternator, the ON/OFF input needs to be connected the vehicles IGN wire or it can be controlled by a manual ON/OFF switch. The ON/
12 Volt / 15 AmpsDC/DC Battery Charger
Designed for all lead acid sealed
Please read the instructions before using.
OFF input needs to see 12V for the DC DC Charger to turn on. Please ensure you use adequate size wiring. The size of wire will depend on the length of wire being used to connect to the input and output. If you’re unsure, please consult a professional or refer to.

CABLE SIZE GUIDE:
Please ensure you have adequate cable size for the output cables. If the output cables are too small, the voltage drop across the cable will cause the battery not to be charged at the correct voltage.
Voltage drop isn’t as critical on the input side, so the cable size can be a little smaller.
The ON/OFF (Switched Ign) wire can be 0.8mm / 18AWG .

TEMPERATURE & SAFETY PROTECTION:
• INTERNAL OVERHEAT PROTECTION: The DC/DC charger has a built-in overheat and an overload electronic circuit. This protects the unit from being damage if overheated or overloaded and will automatically decrease the charging current. Once the units 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’s highly likely that you’re attempting to charge a severely discharged or heavily sulphated battery. If any of the stages time out, the charger will immediately stop charging in order to protect the battery. The Yellow LED 4 will Flash.
• REVERSE POLARITY: The charger has reverse polarity protection. If the charger output leads are connected reverse polarity, the RED fault LED 8 will come on and the charger will be disabled.
• SHORT CIRCUIT PROTECTION: The charger will automatically turn off 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 output accidently touch each other while the charger is turned on.
BATTERY TYPES & CAPACITY:
• Suits 12V conventional lead acid batteries (VRLA) AGM, Calcium, Gel & Wet.
The Ah (Ampere Hours) capacities shown below are to be used as a general guide only. Some batteries may be able to handle a higher charge current. Refer to the battery manufacturers specifications and recommendations for your charging requirements.

THE CHARGING PROCESS:
1) Bulk Charging - (C harge Voltage depends on battery type selection)
Uses the maximum charge output until the battery voltage reaches a selected voltage. If the battery voltage doesn’t reach this within 24 hours, the safety timer protection will stop the unit from charging and LED 4 will be flashing.
2) Absorption Charging
Uses a constant voltage while reducing the charging output current to ensure the battery receives a full charge without overcharging the battery.
3) Equalisation Charging
A well proven process that carefully overcharges the battery to restore it’s full capacity. The
Equalisation charge voltages are shown in the specifications on Page #3.
4) Float Mode - Fully Charged
This stage allows you to keep the charger connected 24/7 to ensure your battery is well maintained and kept 100% fully charged. Float mode will maintain the battery at a constant 13.6V.
