) on the batteries by the amount of reserve time
required. Compute “I
SF
” as described in Section 3.3, Determining Power
Requirements. The equation is as follows:
System Requirement = I
SF
amps  Reserve hrs = _____ amp-hrs
3.5.3 Replacing the Batteries
The battery pack contains three D-size lead-acid batteries providing 2.5
Amp-hours of current at 6.2 volts nominal.
