Figure 5-11, Equalizing Mode

• Equalizing - The battery charger is delivering the equalize voltage
to the batteries; see Table 3-3 to determine the equalize voltage for your
battery type.
Equalize charging can be enabled by the ON/OFF CHARGER pushbutton – if
the SETUP menu's 04 Battery Type selection allows. Equalization charging can
only be enabled while the charger is in Float charge or in Battery Saver mode.
To turn on Equalize charging, ensure the LCD display reads "Float Charging"
or "Full Charge", then press and hold the ON/OFF CHARGER pushbutton down
(about 5 seconds) until the LCD screen displays "Equalizing".
The Equalize charge will continue for 4 hours and then automatically stop
and return to Float charging. The Equalize charge can be manually stopped
by pressing and holding the ON/OFF CHARGER pushbutton down (about 5
seconds) until the LCD screen displays "Float Charging".
During Equalize charge stage the batteries will begin gassing and bubbling
vigorously which consumes water. Ensure each cell has adequate distilled water
levels prior to equalizing, and add water as needed after equalizing.
How often should I equalize? Some experts recommend that heavily used
batteries should be equalized periodically, ranging anywhere from once a
month to once or twice per year. Other experts only recommend equalizing
when the cells have a low specifi c gravity, or when the difference between
any individual cell has a specifi c gravity reading greater than .015 after be-
ing fully charged.
How long should I equalize? While the batteries are gassing, monitor the
specifi c gravity readings every hour. When the specifi c gravity readings no lon-
ger increase, the Equalization charge is complete and should be stopped.
WARNING: Equalizing produces hydrogen and oxygen gas.
Ensure the battery compartment has adequate ventilation to
dissipate this gas to avoid explosions.
CAUTION: Ensure you batteries can be equalized – only equal-
ize your batteries if permitted by your battery manufacturer or
dealer. Performing an Equalize charge on batteries other than
liquid lead acid or certain AGM types could permanently damage
them. Refer to your battery manufacturer/dealer for instructions
on how to properly equalize your batteries.
CAUTION: Ensure the DC loads will not be damaged by the high-
er voltage applied to the batteries during the Equalize charge. If
in doubt, disconnect the DC loads to prevent damage.
Info: Equalization charging is not available if GEL or AGM 2 is se-
lected under the SETUP menu's 04 Battery Type menu.
