drawn from it, it will eventually discharge. The
battery will discharge at a faster rate as its
energy level becomes depleted. It is
recommended you plan your electrical usage
accordingly.
A fully charged 12V batteries will read 12.7
volts DC and 1.265 specific gravity at 80°F
(32°C). The house battery is considered
discharged at 11.8 volts DC by electronic
standards. When voltage drops below those
levels, permanent damage may occur.
Typically, a deep cycle battery has an
amp-hour rating of 75-100 amps. If you run the
furnace and refrigerator simultaneously, you
will be using approximately (12.0 + 3.0) 15.0
amps per hour. This does not include any
12-volt lights, water pump or any other 12-volt
component.
If the furnace and refrigerator in the
above example operated constantly, a
75 amp-hour battery would become
fully discharged in 5 hours (75ah / 15a
= 5h).
Battery storage instructions
Some equipment in your RV will draw small
amounts of current even when turned OFF. To
prevent house battery discharge when the
motorhome is not connected to power through
the shoreline power cord, it is recommended
you shut OFF the 12-volt battery disconnect
switch and disconnect the battery negative
cable at the house battery.
During storage, it is important to check battery
voltage at least every two weeks and recharge
as needed. If you remove the battery from your
RV, store them in a dry, cool area as per the
OEM instructions.
Replacement and maintenance
For accuracy, test battery voltage using a
volt-ohm meter (customer supplied). When it is
time to replace the house battery, replace it
with a Group 27 deep cycle battery only.
Contact the battery OEM for further
information. Do not reverse the positive and
negative battery cables. Doing so will blow the
reverse polarity fuses that protect the
converter.

ATTERIES
Each OEM chassis is built with batteries to
provide energy to start the engine and operate
devices supplied with the chassis. These
batteries are located under the passenger side
front door step. The original equipment
manufacturer (OEM) chassis battery is
furnished and warranted by your GM or Ford
dealership (as applicable).
Recharging the chassis battery
If the motorhome has a discharged battery,
you may use booster cables to obtain a start
from a booster battery or from the battery in
another vehicle. This type of start can be
dangerous if done improperly, so follow this
procedure carefully:
1. Remove any metal jewelry, such as watch
bands or bracelets. They might make
inadvertent electrical contact.
2. When boost is provided by a battery in
another vehicle, park both vehicles within
booster cable reach. Keep the engine of
the assist vehicle running. Use care not to
have the booster cable caught in the
cooling fan or other rotating part in the
engine compartment. Do not allow the
vehicles to touch.

WARNING
Always wear eye protection when
working with batteries.
Keep sparks,
cigarettes and flames away from the
battery because the battery may explode.
Do not use a booster battery or any other
power source that has an output that
exceeds 12-volt. Use adequate ventilation
when charging or using the battery in an
enclosed space.
