Battery Discharge Indicator (BDI)
Since the new battery charge has not changed
by at least 50% and the state
-
of
-
charge of the
new battery is not greater than the BDI reset
configured value, the Operator Display
continues to show the old battery's charge of
45% (even though the new battery is at 92%).
What occurs is that the Operator Display
remains at 45% until the charge of the new
battery declines to 45%. Then the display
resumes its normal descent.
One final example. Assume the following:
BDI configured at 95%, the battery
connected is at 65% charge, and the new
battery is at 20% charge.
Again, the change in charge is not at least 50%
and the new battery is not above the configured
BDI level. The Operator Display continues to
show
65%, but then descends rapidly as the lift
truck operates until the Operator Display
shows the original charge of 20%. Once the
display shows
20%, it resumes a normal
descent.

Charge
Cutout
1.
Fill, charge, and install a battery that is
typical of the batteries normally used in
this application.
2. Have a customer operator use the lift
truck in normal application until cutout
occurs.
3.
Permit the battery to cool and stabilize for
at least two hours.
4.
Before filling the battery, either take
specific gravity readings or measure open
circuit voltage of the battery cells.
5. Compare the measurements with the
battery manufacturer's recommendations
for maximum discharge.
6.
Adjust the cutout value as needed and
repeat the previous steps until battery
cutout occurs at the desired discharge
level.
