st
Stage: Desulfation:
Focused on deeply discharged or lightly sulfated batteries, which show
low voltage and are hard to activate. The SCM54E Charger will start the
charge pulse to charge the battery until the voltage recovers & reaches
expected rechargeable level. The purpose of this stage is to save an
over-discharged or a lightly sulfated battery for recovery.
2
nd
Stage: Fast Charge:
When the voltage of the battery is above the set level. The SCM54E
Charger carries a high current to charge the battery quickly until the
battery is returned to 75% of the charge. The purpose of this stage is to
charge battery in the fastest and most efficient manner.
3
rd
Stage: Equalization & Analysis:
When the voltage reaches a maximum safe (pre-determined) voltage,
The SCM54E will discontinue the Fast Charge automatically & start a
charge pulse with a smaller steam current to charge the battery. The
purpose of this stage is to fully charge the battery in safe manner.
4
th
Stage: Top-Off Charge:
Under this stage, the SCM54E Charger will shut off automatically when
the battery is 100% charged. The charger will monitor the battery
voltage continually to decide whether a new charge pulse should come.
The purpose of this stage is to fully charge the battery without
overcharging the battery.
5
th
Stage: Maintain Floating:
If the voltage drops below the pre-set level by battery self-discharge, the
SCM54E Charger starts a charge pulse with a small current to maintain
the battery in full-charge status. The cycle is repeated as long as the
charger is in “Maintain Floating” mode
