THE CHARGING PROCESS: LEAD ACID
(Gel, Calcium SMF, AGM&WET/EFB)
1) Qualification - Battery Condition Check
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 that the
battery will accept.
2) Automatic Enhanced Battery Rejuvenation - Blue Charging LED Double Flash
If the initial qualification 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.
Manual Enhanced Rejuvenation Mode
To manually rejuvenate your batteries, simply press and hold both the Battery Type and Charge
Rate buttons simultaneously for 3 seconds until the Blue Bulk LED flashes (Double flash). This
mode will last for 24 Hours. To stop rejuvenation mode, press and hold both the Battery Type
and Charge Rate buttons simultaneously for 3 seconds until the Blue Bulk LED stops flashing
rapidly.
Important Note:
Please check your Battery Type and Charge Rate selection to ensure you
haven’t accidentally changed these settings.
3) Soft Start Charging - Blue Charging LED Flashing Slow (Single Flash)
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 flashing.
4) Bulk Charging - Blue Charging 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 flashing and the Blue Bulk LED will be ON.
5) Absorption Charging - Blue Charging LED ON and Green Full LED Flashing
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 Charging LED and Green Full LED both flashing
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(EFB) 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
flashing.
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.
9) Long Term Maintenance - Full 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.
