5.0 Operation
• Equalizing
Mode
– The battery charger is delivering the equalize
voltage to the batteries. Refer to Table 3-3 to determine the equalize voltage.
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
” or “
Full Chg
”, press the MENU button until you
see the “
EQUALIZE Disabled
” menu, and then press the CHANGE button.
The display quickly reads “
EQUALIZE Request
”, and then “
EQUALIZE EQing
.”
The Equalize Charge continues for four hours, and then automatically stops
and returns to Float Charging. The Equalize Charge can be manually stopped
by pressing the MENU button until you see the “
EQUALIZE EQing
” menu, and
then pressing the CHANGE button. The display will read “
EQUALIZE Disabled
”.
During equalization, the batteries begin gassing and bubbling vigorously
(which consumes water). Ensure that each cell has adequate distilled water
levels prior to equalizing, and be sure to add water as needed after equalizing.
How often should I equalize?
Some experts recommend heavily used
batteries should be equalized anywhere from x1/mo. to 1-2x/year. Others
only recommend it when the cells have a low speci
fi
c gravity, or when the
difference between any individual cell has a speci
fi
c gravity reading greater
than .015 after being fully charged.
How long should I equalize?
While the batteries are gassing, monitor the
speci
fi
c gravity readings every hour. When the speci
fi
c gravity readings no
longer increase, the Equalization Charge is complete and should be stopped.
WARNING:
Equalizing produces hydrogen and oxygen gas. Ensure
the battery compartment has adequate ventilation in order to dis-
sipate this gas to avoid explosions.
CAUTION:
Ensure your batteries can be equalized. Performing an EQ
charge on batteries other than liquid lead acid or certain AGM types
could 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 higher
voltage applied to the batteries during equalization. If in doubt,
disconnect the DC loads to prevent damage.
Info:
Equalization is not available if
GEL
or
AGM 2
is selected from
the
Battery Type
menu.
EQing
appears on the LCD. The
FAULT (red) LED is off, and the INV
(green) LED could be on or off.
