Charging Stages

This charger features a 7 stage charging program. Each stage automatically switches from one to the
next without any user input.

DESULPHATION
NOTE: Voltages and charging algorithm vary between battery types to ensure that battery is charged and maintained in
optimum manner for selected battery type.
Desulphation:
In this initial start up stage, a high frequency voltage pulse assists in "waking up" a deeply discharged
battery. This method of pulse charging can also help reduce the build up of sulfate crystals that may
have formed on the battery plates during the time it was discharged. This stage will last as long as it
takes the battery to reach approximately 10 volts. If the connected battery is only slightly discharged,
this stage may only be activated for a short time before automatically switching to the next soft start
stage.
Soft Start:
After the battery is connected most conventional "Smart" battery chargers will immediately apply a
high charging voltage and current output. This creates a large amount of gassing and heat generated
by the battery that can cause uneven battery cell voltages. Uneven cell voltages can cause individual
cell overcharging or undercharging, lessening the overall life span of your battery. The soft start
function eliminates this by starting the charge process slowly; battery electrolyte and cell voltage is
given a chance to even out prior to the main bulk charging processes, greatly increasing the batteries
charging capability.
Bulk:
This is the main charging stage, where the charger will operate at its maximum output current and
voltage until it reaches the correct levels as required from the selection made with the battery selector
button (different battery types require different charge levels). The charging period of this stage is
determined by the capacity and charge state of the connected battery and will fluctuate between
different battery types.
