13. OPERATING INSTRUCTIONS
(CONTINUED)
b) If positively earthed, FIRST connect the black (-) battery charger lead
to the negative (-) battery post and then connect the red (+) battery
charger lead to the vehicle’s chassis and far away from the fuel line.
13.3 STEP 3 – Connect the battery charger to mains power (120 Vac)
a)
Note:
If the fault indicator LED illuminates red, please check your
connections as it is likely that the positive and negative leads are
reversed. The fault indicator may also illuminate if the 6 V setting
has been selected for a 12 V battery, as long as the 12 V battery’s
state of charge is over 8 V.
b) The charger will automatically start when AC power
is connected and switched on.
14. THE CHARGING PROCESS:
14.1
Qualification – Battery condition check – orange charging LED flashing rapidly
When the charger is first switched on, it checks the battery condition to determine whether the battery needs reconditioning.
During this qualification process, it checks the internal impedance and initial voltage of the battery and it will determine how
much charge current, if any, the battery will accept.
14.2
ENHANCED BATTERY REJUVENATION – ORANGE CHARGING LED FLASHING RAPIDLY
If the initial qualification detected that the battery is in poor condition, the patented rejuvenation process will begin automatically.
During the rejuvenation process, a high voltage equalizing and peak pulse reconditioning charge is used to repair the sulfated
battery. This unique patented feature will break down and dissolve the lead-sulfate crystal build-up on the battery plates, extending
the life of your battery. It can also balance out high concentrations of acid. The equalization voltage will be 8 V maximum for 6 V battery
selection and 16 V maximum for 12 V battery selection.
14.3
Soft start charging – orange charging LED flashing slowly
Gently charges the battery using a reduced charge output until the battery voltages reaches 5.5 V for 6 V battery selection or 11 V
for 12 V battery selection. If the battery voltage doesn’t reach these levels within six hours, the safety timer protection will stop the
unit from charging, the red fault LED will illuminate and the orange charging LED will start flashing.
14.4
Bulk charging – orange charging LED ON
Uses the maximum charge output until the battery voltage reaches 7.2 V for 6 V battery selection or 14.4 V for 12 V battery selection.
If the battery voltage doesn’t reach these levels within 24 hours, the safety timer protection will stop the unit from charging and the
red fault and orange charging LEDs will illuminate.
14.5
Absorption charging – orange charging LED ON
Uses a constant voltage while reducing the charging output current to ensure the battery receives a full charge
without overcharging the battery.
14.6
Battery analysis – full/float green 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, battery is probably faulty. If the battery analysis failed, the green full LED will flash.
14.7
Float mode – full/float green LED ON
This stage allows you to keep the charger connected 24/7 to ensure your battery is well maintained and kept fully charged.
Float mode will maintain the battery at a constant 6.6 V for 6 V battery selection or 13.2 V for 12 V battery selection.
14.8
Long-term maintenance – full/float green LED ON
During long-term maintenance/float mode, the unit will apply a special pulse charge to ensure the battery is kept in optimal condition.
15. STEP 4 – Disconnecting the battery charger from the battery
15.1
If the battery is outside the vehicle:
1. Switch the charger OFF and remove it from the outlet.
2. Remove the black lead and then the red lead.
15.2
If the battery is still in the vehicle:
1. Switch the charger OFF and remove it from the outlet.
2. Remove the lead from the vehicle chassis.
15.3 Remove the lead from the battery.
15.4
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).
