TEMPERATURE & SAFETY PROTECTION:
• INTERNAL OVERHEAT PROTECTION: The charger has a built-in overheat and an
overload electronic circuit. This protects the charger 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. This will be indicated
with the fault LED ashing slowly.
• 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 c
onnect 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 accidently touch each other while the charger is turned on.
• ECO MODE: This 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.
Both the selected Charge rate and Battery type LED’s will ash GREEN to indicate
ECO mode.

CHARGING INSTRUCTIONS:
STEP 1 - Pre charge check & electrolyte level check
• Check the Battery Electrolyte levels (Not required on sealed & maintenance free
batteries). If necessary, remove the vent caps and add distilled water so the levels are
halfway between the upper and lower ll lines.
• Check the battery voltage, type and Ah capacity to ensure the charger is compatible
and to determine which Battery Type and Charge Rate settings you will use.
• Ensure the battery is in a well ventilated area and the charger should be as far away
from the battery as the cables permit.

STEP 2 - Connecting the battery charger to your battery
• If the Battery is out of the vehicle:
- Connect the Red (+) Crocodile clip or optional ring terminal to the (+) battery terminal.
- Connect the Black (-) Crocodile clip or optional ring terminal to the (-) battery terminal.
• If the battery is still in the vehicle, determine if the vehicle is positively or negatively earthed.
If Negatively Earthed (Most Common) – FIRST Connect the Red (+) Crocodile clip or optional
ring terminal lead to the (+) battery terminal and then connect the Black (-) Crocodile clip or
optional ring terminal lead to the vehicle’s chassis. DO NOT connect the Black (-) lead to the
carburettor or fuel lines.
If Positively Earthed – FIRST Connect the Black (-) Crocodile clip or optional ring terminal lead
to the (-) battery terminal and then connect the Red (+) Crocodile clip or optional ring terminal
lead to the vehicle’s chassis. DO NOT connect the Red (+) lead to the carburettor or fuel lines.
STEP 3 - Connect the battery charger to Mains Power (240Vac)
• The charger will automatically start when AC power is connected and switched on.
• IMPORTANT: Please make sure the correct Battery Type and your desired Charge Rate is
selected to suit your battery by pressing the Select Buttons within the rst 5 minutes of
charging. For Example do not charge a Gel Battery on the Calcium Battery Type setting as this
may damage your battery and / or reduce your battery life.

THE CHARGING PROCESS:
1) Qualication - Battery Condition Check
When the charger is rst switched on it checks the battery condition to determine whether the
battery needs reconditioning. During this qualication process it checks the internal impedance
and initial voltage of the battery and it will determine how much charge current, if any that the
battery will accept.
2) Enhanced Battery Rejuvenation - Blue Bulk LED Flashing Fast
If the initial qualication detected that the battery was in poor condition, the patented
rejuvenation process will begin automatically. During the rejuvenation process a high voltage
equalising and peak pulse reconditioning charge is used to repair the sulphated battery. This
unique patented feature will break down and dissolve the lead-sulphate crystal build up on the
battery plates which will extend the life of your battery. It can also balance out high
concentrations of acid. The equalisation voltage will be 16V maximum. If the battery voltage
doesn’t reach 9V within 24 hours, the Rejuvenation process will time out.
3) Soft Start Charging - Blue Bulk LED Flashing Slow
Gently charges the battery using a reduced charge output until the battery voltages reaches
11V. If the battery voltage doesn’t reach 11V within 6 hours, the safety timer protection will stop
the unit from charging and the Red Fault LED and Blue Bulk LED will start ashing.
4) Bulk Charging - Blue Bulk LED ON (Charge Voltage depends on battery type selection)
Uses the maximum selected charge output until the battery voltage reaches 14.1/14.4/14.7V. If
the battery voltage doesn’t reach this within 24 hours, the safety timer protection will stop the
unit from charging and the Red Fault LED will start ashing and the Blue Bulk LED will be ON.
5) Absorption Charging - Green Absorption LED ON
Uses a constant voltage while reducing the charging output current to ensure the battery
receives a full charge without overcharging the battery.
6) Equalisation Charging - Blue Bulk LED and Green Absorption LED both ashing
A well proven process that carefully overcharges the battery to restore it’s full capacity. The
Equalisation stage for CALCIUM Battery type selection is automatic. The Equalisation stage for
AGM&WET and GEL Battery Types only occurs if the initial start voltage is below 11 Volts.
7) Battery Analysis - Green Full LED ON
The battery analysis stage checks the condition of the battery after the charge cycle is
completed. If the battery voltage drops too quickly during the analysis mode, this means the
battery is probably faulty. If the battery analysis failed, this is indicated by the Green Full LED
ashing.
8) Float Mode - Full Green LED ON
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.

7 www.batterytown.co.nz
9) Long Term Maintenance - Full Green LED ON
During long term maintenance / oat mode, the unit will apply a special pulse charge to ensure
the battery is kept in optimal condition.
STEP 4 - Disconnecting the Battery charger from Battery
• If the Battery is out of the vehicle:
(1) Switch OFF and Remove the AC Power Socket from the outlet.
(2) Remove the Black lead and then the Red lead.
• If the battery is still in the vehicle:
(1) Switch OFF and Remove the AC Power Socket from the outlet.
(2) Remove the lead from the vehicle chassis.
(3) Remove the lead from the battery.
Note: Check electrolyte levels if possible after charging as they may need topping up with distilled
water. (This does not apply to sealed maintenance free batteries)
