Battery Description
Starting batteries are usually the lead-acid type. Use a
12-volt group 51 battery with a minimum rating of 500
cold cranking amps at 0F. The generator set uses a
negative ground with a 12-volt engine electrical system.
See Figure 3-5 for battery connections. Make sure that
the battery is correctly connected and the terminals are
tight.
Note: The generator set will not start and circuit board
damage may occur if the battery is connected in
reverse.

Figure 3-5 Typical Battery Connection
See the dimension drawing in Section 6 for the engine
starting battery location on the air intake side of the

Use the following procedure to install and connect the
battery.
Battery Installation Procedure
1. Ensure that the starting battery is fully charged
before placing the battery in service.
2. Clean the battery posts and/or adapters if
necessary.
3. Install the battery post adapters, if needed.
4. Place the battery in the housing.
5. Connect the positive (+) lead to the engine starting
battery.
6. Connect the negative (- ) lead to the engine starting
battery.
Refer to the generator set operation manual and the
battery manufacturer’s instructions for battery
maintenance instructions.
When power is applied to the RDC2 controller (that is,
when the battery is connected), you will be prompted to
set the date and time, and then to set the exerciser. See
Section 4.2 and the generator set operation manual for
instructions.
If the battery is disconnected for service or replacement,
the exercise settings on the RDC2 controller are lost.
Set the exerciser after installing and connecting the
battery. See Section 4.2, Set Exerciser.
