Battery Voltage

Figure 9. Multicell Battery for Electric Lift Truck
NOTE: The voltage of the battery can be found on the
lift truck's Nameplate. See the Frame section or
Operating Manual for your lift truck for the location of
the Nameplate.
The battery voltage you need is found as follows:
Will your lift truck operate on more than one
•
voltage?
If you have more than one lift truck in operation,
•
do the battery voltages need to be the same?
On electric lift trucks that use the battery as part of the
counterweight, the battery is part of the capacity of the
lift truck to lift loads. The minimum weight of the
battery is shown on the nameplate. If the battery is not
the minimum weight, the capacity of the lift truck is
reduced. If the battery used in the lift truck is less than
the size of the battery compartment, blocks and
The ratings of batteries are measured in ampere-hours
and kilowatt-hours at a constant rate of discharge. A
rating of 6 hours is the standard. Ampere-hours is the
measurement of battery capacity. To calculate ampere-
hours, multiply amperes by hours. See Table 1. For

Battery Ratings

To reach the necessary battery voltage, the cells are
connected in series. For example:
24 volts = 12-cell battery
36 volts = 18-cell battery
48 volts = 24-cell battery
72 volts = 36-cell battery
80 volts = 40-cell battery
spacers must be installed to hold the battery in
position.
See the Frame or Periodic Maintenance service
manual or Operating Manual for your lift truck model
for the correct measurements for installing battery
spacers.
example, 5 amperes times 5 hours is 25 ampere-
hours. You cannot change the potential difference of a
cell. You can increase the ampere-hour rating by
increasing the number of plates in a cell, or by
installation of larger plates. The constant rate of
