DESCRIPTION
Six 12-volt lead acid (nine 8-volt 6-passenger &
long back extra duty model option) batteries supply
72-volt power for the vehicle. Two are located
under the spat or under the bed of the vehicle. Four
are located under the front cushion on two-
passenger models, and under the rear seat cushion
on four-passenger models. Three under middle
section bucket seat, 6-passenger models (option)
and 6 batteries under the seat cushion on the
6-passenger and long back extra duty models
The batteries supplied with the GEM electric
vehicle are deep cycle marine batteries. They are
designed to handle discharges down to 20-30% of
their rated capacity without doing any internal
damage. Since the batteries in the electric vehicle
must supply 100% of the energy required for
operation, they are subject to deep discharges and
then must be recharged to restore their capacity. In
comparison, the standard automotive battery is
known as a starting, lighting, and ignition (SLI)
battery. It is designed to supply a very high
cranking current for a brief period and then
maintains the accessory loads on the car.
NOTE: Due to
characteristics of the two types of batteries,
automotive type starting batteries should never
be substituted in place of a deep cycle marine
battery.
