Step 3: Disconnect battery cables from charger
NOTE: If the operator disconnects the cables without pressing STOP, the charger will
immediately stop charging and prevent any arcing or damage to either the charger or
battery. However it is strongly recommended that operators press the STOP button first.

5.4 Equalization

Proper equalization is necessary for the health of the pack. Too little equalizing may lead to
sulfation and decreased capacity, whereas excessive equalizing may lead to high water loss
and more maintenance. We recommend equalizing at least once a week, but twice a week is
optimal for pack life under continuous use.
The equalization schedule is stored in the BMID and run automatically (see the "BMID
Programming and Advanced Features Manual" for information on how to modify the pre-set
equalization schedule). To manually schedule an equalization during a charge, simply press
the "Equalize" button at any time during a charge, the equalize light will start flashing indicating
an equalization is scheduled, and the battery pack will be equalized following the fast charge.
To bypass the fast charge and start an equalization charge on a battery pack at any state of
charge, press and hold the "Equalize" button for three (3) seconds, the equalize light will
illuminate without flashing, and the charger will start a full equalization on the pack without a
fast charge.
To cancel a requested equalization charge, press the Equalize button and the Equalize LED
will turn off.

Always run a full equalization charge prior to a fast charge on any battery
pack that has had a cell replaced to ensure the pack is balanced.
