BATTERIES
To prevent accidental starting of the genset during
installation, do not connect the battery cables at the
battery until so instructed in the
Installation Checks
and Start-Up
section.
WARNING
Accidental starting of the genset
can can cause severe personal injury or death.
Do not connect the starting battery until so
instructed in the
Installation Checks and Start-
Up
section.
Onan does not recommend that the vehicle starting
battery be used to operate the genset. Doing this
can discharge the battery under some operating
conditions.
Battery Capacity
The genset has a 12 VDC, negative-ground control
and starting system. See Table 7-1 for minimum
battery capacity requirements.

Battery Recharging
The majority of gensets are not equipped with a bat-
tery charger. Other means will have to be provided
for maintaining the battery charge level.
A kit is available for field installation of the battery
charger. See your Onan distributor for information.
Battery Compartment
Mount the battery in its own compartment, away
from the genset and any spark-producing device.
For ventilation, provide the battery compartment
with an opening of at least 1.7 in
2
(11 cm
2
) at the top
and 1.7 in
2
(11 cm
2
) at the bottom.
