CHARGE CYCLES
Stage Function Description
1
Diagnosis
To determine whether the battery is defective. Charging will not
proceed if the battery voltage is <0.5V and an "Error Code" will be
displayed on the LCD.
2
Desulphation
This stage provides a stepped or pulsed voltage to help remove the sul-
phation of plates which can occur when batteries are left discharged for
prolonged periods. It also stabilises electrolytic balance and minimises
excessive battery temperature.
3
Pre-Charge
A low voltage and current is used to slowly increase battery condition
and further improve electrolytic consistency which can become uneven
due to day to day use.
4
Soft Start
At an increased voltage, the current is slowly increased over time to
control heat, reduce gassing, and minimise battery stress.
5
Bulk Charge
(Constant Current)
Initially, maximum current is applied to the battery however, the three
phases of the stage reduce the time to charge, control electrolytic
loss, and enhance battery health and life.
CC1 CC1- Charging at maximum current.
CC2 CC2 - Current is reduced.
CC3
CC3 - Current is further reduced for improved charge whilst minimising
electrolyte loss and excess temperatures.
6
Absorption
(Constant Voltage)
Applying an even higher voltage whilst reducing current over time
ensures the battery is topped up but not over-charged.
7
Analysis
The charger conducts an analysis of the battery over a period of
time to determine the battery discharge rate. Based on the battery
performance, the battery charger will recommence charging, or move
to the next stage
8
Recondition
(High Voltage Repair)
The recondition phase applies maximum voltage to maximise battery
condition and further repair and clean battery plates. This may be
required following significant discharge, for batteries with uneven cell
capacity or, to alleviate acid stratification when Calcium batteries are
left discharged for more than a couple of days.
Note - The battery charger will assess the condition of the battery and
may not perform this function.
9
Maintain
The battery charger monitors the battery voltage and recommences the
charge sequence when the voltage drops to 12.8V (or 6.4V).
