Absorption (Constant Voltage)
The chargerateslow s downsothebattery canabsorbmorepower
and reach100%charge.The voltageremains at a constant14.5volts
for 12V charger whilethecurrentis gradually reduced until no more
power canbe addedw ithoutover-chargingthebattery.
BatteryTest
Anautomatic battery testis conductedimmediately after theabsorption
stage.The test monitors the voltage for90seconds todetermine if the
chargew as successful.
◆12V charger If thevoltage is below 13.2volts (fail), the charger will
initiate the Recondition stage.
◆12V charger If thevoltage is above13.2volts (pass), thecharger will
proceedtothe final stage:Float.
Recondition
The battery reconditioningfunctionis initiated automatically in thecase
that the battery fails thebattery test(stage5). Failing the battery test
indicates that the absorptionstagewas unabletofully chargethe
battery.The reconditionmode willthenbegin to introducea low
constantcurrentfor a periodof 4 hours. Then the charger w illgo into
floatchargingmode.

RECOND- This mode is used to recover deepdischargedflooded
