BATTERY SELECTION & INSTALLATION
The 12 VDC battery is not furnished with the standby
generator set. The generator can be installed in a
wide range of temperatures and climate conditions.
As climates get colder, batteries loose their ability to
produce required power. Therefore, battery size
must be increased. Installer must provide proper
battery size, depending on environment.
Climates that reach to a low of 20º F (-6.7º C) can
achieve good generator operation with a 12 VDC,
925 CCA battery. Climates that reach below this
temperature line should have a 10-20% increase in
CCA rating for a 12 VDC battery. See Battery Chart
on page 17.
CAUTION: All 12 VDC batteries will loose a certain
percent of their charge while in storage. It is very
important to test the battery voltage before it is
installed in generator and taken to jobsite. A fully
charged battery must test at 12.5 – 13.0 volts DC.
Also, the correct battery must have lug terminals to
match lug battery cables, for a bolt-together
connection. When replacing batteries, use the
same number and the following type batteries:
Sealed type:lead-acid
(1) 20-60 KW 1800 RPM sets 650 C.C.A. or 55 amp/hour
(1) 80-210 KW 1800 RPM sets 710 C.C.A. or 65 amp/hour
This generator is equipped with a corrosion resistant
battery tray, a battery hold down strap and battery
cables. Place the selected fully charged battery with
full electrolyte in battery tray and secure with battery
hold down strap.
Before connecting battery cables to battery,
complete the following steps:
Battery cables are factory connected at the generator
points (red engine starter motor (positive) cable and
black ground (negative) cable). Electrician should
connect the red battery cable (from engine starter
solenoid point) to battery post shown with “positive”,
POS, or (+) indicator. Connect the black battery ca

bles (from frame ground) to the battery negative
post. NOTE: Both positive and negative battery
cables have protective “boots” that enclose the cable
connections to battery posts. Also, positive battery
cable is secured, so that, if cut or disconnected in any
way, positive cable won’t touch metal door or cable
restraint or boots, as both are required safety
measurements.
Dielectric grease should be used on battery lugs or
posts to help in the prevention of normal corrosion.
Damage will result to generator controls, if battery
cables are made in reverse connections.
Inspect, clean, or re-grease battery connections ever
60-90 days.
In cold climate areas, where temperatures normally
reach 10º F (-12º C) or colder, an optional battery
wrap-around heater, controlled by thermostat,
should be used, for increased battery power.
This generator is equipped with an automatic “float
type” 3-stage (bulk, absorption, and float) battery
charger, energized by utility power, to maintain full
battery power while on standby (non-running)
condition. CAUTION: This charger can not recharge
a fully discharged or defective battery.
● Do not dispose of battery in a fire. The
battery is capable of exploding and
spewing electrolyte in several directions.
● Do not open up a battery. It has
electrolyte and is harmful to the skin and
eyes, and is toxic.
● Battery
electrolyte is electrically
conductive and corrosive.
● Contact with battery acid will cause severe burns
to the skin and eyes.
A battery can cause an electrical shock. Before
working on a battery, follow safe procedures:
● Remove start/stop 10 amp fuse in control circuit.
● Remove all rings, watches, & other metal objects.
● Wear rubber gloves and boots.
● Use tools with insulated handles.
● Do not lay tools or metal objects on top of battery.
