2240 YRM 0001
NOTE: The capacity 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 needed to operate a period of 8 hours
depends on many conditions. Operations that require
the lift truck to go up ramps or require the use of
additional attachments increase the use of power from
the battery. Some work conditions require that more
than one battery must be used during a work period.
The number of 8-hour work periods per day is normally
equal to the number of batteries needed. For example,
for three work periods, you need three batteries. The
capacity of the battery you need is found as follows:
The size of the lift truck and the attachments.
•
The type of work. Heavy-duty operation or
•
normal operation for one 8-hour work period.
Lift trucks are available in various voltage ranges. See
Figure 8. The small "walkie" lift trucks are normally 12
or 24 volts. The larger sit-down rider lift trucks are
normally 24, 36, 48, 72, or 80 volts. The number of
cells in a lead-acid battery gives the battery voltage.
See Figure 9. A fully charged cell has a potential
difference of approximately 2 volts. See Figure 8. This
potential difference does not change with size of the
cell.
