Figure 5-15, Equalizing Mode
Equalizing - The battery charger is delivering the equalize voltage to the
batteries; see Table 3-3, Battery Type to Charge Voltages to determine the
equalize voltage for your battery type.
Equalize charging can be enabled by the ON/OFF CHARGER button - if the
Setup 03B Battery Type selection allows. Equalization charging can only be
enabled while the charger is in Float charge or in Full Charge mode. To turn
on equalize charging, ensure the LCD display reads "Float Charging" or "Full
charge", then press and hold the ON/OFF CHARGER button 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 button down (about 5 seconds)
until the LCD screen displays "Float Charging".
During Equalize charge mode 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 being fully
charged. Contact your battery manufacture for their recommendations.
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 in order to dis-
sipate this gas to avoid explosions.
CAUTION: Ensure your batteries can be equalized. Only equalize
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 higher
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 selected
under Setup 03B Battery Type menu.
