battery set to maintain a constant voltage. As the battery set nears a full
charge, the current needed to maintain this voltage decreases. Once the
current falls below a 0.10A change per hour, the stage is complete. It will
be in this stage for a minimum of one hour.
• Battery Test is administered by reading your battery set's voltage while
resting the battery set for 10 minutes. A voltage of under 50.0V indicates
a weak battery set, under 46.0V indicates a shorted cell. The battery
set is tested at completion of the Constant Voltage stage, and every 12
hours while in Float.
• Float (sometimes called Maintenance) is the maintenance-charger’s
long term stage. The maintenance-charger can and should be left
connected indefinitely. This will keep the battery set fully charged
ensuring no sulfate can form. The maintenance-charger maintains float
voltage using very little power as it actively monitors the battery set and
adjusts its output several times a second.
Indicator Light Details
• Power light is GREEN anytime the maintenance-charger is plugged into
AC Power.
• Battery Connection light is GREEN when the unit it is correctly
connected to a battery set. If the Battery Connection light is RED the
polarity is reversed. The positive and negative terminals need to be
switched or there is a short circuit.
• Battery Weak light is AMBER if the Soft-Start mode is used or the
battery set fails a Battery Test. The indicator will stay on until the battery
set passes a Battery Test.
A neglected battery set can take over 2 weeks of desulfation to correct.
If after 2 weeks it still reads as a Weak Battery, there is likely internal
physical damage.
• Bad Cell if the battery set is under 46.0V after a Battery Test.
The maintenance-charger shuts off output to avoid any damage to your
battery set. Loads or banks of batteries may trigger this mode if they are
too large for this maintenance-charger.
• Testing light is BLUE when the unit is performing a Battery Test (see
Charging Stages).
• Desulfation light flashes BLUE any time the unit is desulfating. The
