2.4.1 Charging indicator (Orange)
This indicator is used during the fi rst three stages of charging (Boost, Absorption and
Equalise), and fl ashes at different rates to indicate the charging mode.
Boost Mode
: Orange indicator ON-single fl ash. This mode delivers the bulk charge to the
battery by delivering maximum constant current. This stage is time limited to cater for a
fully discharged 40Ah battery, however the time taken in this mode does greatly depend
on the condition and state of charge of the battery.
Absorption Mode
: Orange indicator ON-double fl ash.
This mode must be fi nished before Equalise can take place. The charger maintains
constant charging voltage, while the current reduces. This voltage is close to the gassing
voltage of the electrolyte.
Equalise Mode
: Orange indicator ON – triple fl ash.
This mode brings the battery to full charge. A higher voltage is applied to induce some
gassing, which mixes the electrolyte, bringing the cells to equal potential. In a low
maintenance battery, most of the hydrogen and oxygen gasses will recombine and will
not dry out the battery.
Note that this mode is not run for Gel/AGM batteries.
2.4.2 Ready indicator (Green)
Continuously ON
: Indicates that the battery charging process is complete, and full
charge (100%) has been achieved. The charger is now in the maintenance mode (Float),
where it will keep the battery at full charge indefi nitely without the fear of overcharging.
The battery is ready for use, and can be disconnected.
Flashing
: Indicates that the battery charging process is complete, and full charge (100%)
has been achieved. The charger is now in the maintenance mode (Float), where it will
keep the battery at full charge indefi nitely without the fear of overcharging. The battery
is ready for use, and can be disconnected.
