Desulphation
The Desulphation stage is designed to break down sulphation that occurs in batteries that have been
left discharged for extended periods of time, this process assists in revitalizing the battery.
Sulphation occurs when lead-sulphate hardens and clogs up the battery cells.
Soft Start
A preliminary charge process that reduces the initial current into the battery. This protects the battery
from any high start up current from the charger and increases battery life and performance.
Bulk (Maximum Current)
Chargers the battery with the rated maximum output current until approximately 80% capacity. This
stage continues until the battery's terminal voltage has risen above the set limit (depending on
battery type). If the terminal voltage has not reached the set voltage limit within the pre-set time, the
charger switches to fault mode (Stage 3 LED solid) and discontinues the charging process. If so, the
battery is faulty or its capacity is too large.
Absorption (Constant Voltage)
This stage ensures the battery reaches a fully charged state by gradually reducing the current and
maintaining a constant voltage until the battery is 100% charged.
◆ 12V charger: If the voltage is below 13.2 volts (fail), the charger will initiate the Recondition stage.
◆ 12V charger: If the voltage is above
13.2 volts (pass), the charger will proceed to the Float Stage.
◆ 24V charger: If the voltage is below 26.4 volts (fail), the charger will initiate the Recondition stage.
◆ 24V charger: If the voltage is above 26.4 volts (pass), the charger will proceed to the Float Stage.
Analyse
An automatic battery test is conducted immediately after the absorption stage. This test monitors the
battery voltage for 90 seconds to determine if the charge was successful.
Recondition
This stage is automatically introduced if the battery is unable to hold a charge after the Analysis
Stage. The Recondition Stage can recover batteries from a deeply discharged state, rejuvenating the
output capacity and extending the battery life.
The Recondition stage will run for 4 hours and at the end will conduct a test to determine if the
battery is now holding charge. If the battery fails this test the charger will display a fault.
Float
The Float Stage maintains the fully charged state without overcharging or damaging the battery. This
means the charger can be left connected to the battery indefinitely. The battery is fully charged and
can be disconnected at this stage.
Maintain
Designed to maintain the battery at 95-100% capacity over extended periods of time. The charger
monitors the battery voltage and gives a Maintain when necessary to remove plate sulphation and
keep the battery fully charged. This Maintain cycle is repeated infinitely over a 10 day period if left
connected. If the terminal voltage drops below the set level or is disconnected, the charger
automatically goes back to the beginning of the charging cycle.
Featuring the latest technology in battery chargers, switch mode chargers convert 240V AC power to
12V/24V DC power using electronic components unlike traditional battery chargers that rely on
heavy transformers. This allows the charger to be light weight and compact without sacrificing
performance.
