Ouse Battery - Jayco SENECA 2010 Owner's Manual

which connects or disconnects the house
batteries dependent upon the number of times
it is pushed. When energized, the battery
disconnect solenoid supplies battery power to
all accessories connected to the house 12-
volt fuse panel. The 12-volt battery disconnect
switch is used to disconnect the RV from
house batteries power during periods of
storage or during service. The switch must be
activated for the 12-volt house electrical
system to operate.
The LP leak detector must be connected to a
constant power source. If the 12-volt battery
disconnect is off it WILL NOT PROVIDE
power to the LP leak detector.

OUSE ATTERIES
Your RV has many 12-volt DC loads. When
combined, their total is more than the
converter can produce. High demands for 12-
volt power can be met by the house batteries
for limited periods of time. The 12-volt DC
electrical system is designed for usage with a
Group 27, deep
motorhome, the house batteries are usually
referred to as the house (or coach) battery.
The house batteries are factory-installed to
provide temporary 12-volt power when 120-
volt power is not available to operate the
power converter. When drawing energy from
the batteries, remember that there is a limited
amount of power
batteries need to be recharged.
To recharge the house batteries
When the engine is running, the alternator will
automatically charge the batteries through the
auxiliary start solenoid. When parked at a
campsite, plug into shoreline power. With
minimal or low load on the 12-volt electrical
system, the converter
charge the batteries. This may take several
hours and depends upon battery condition
and the number of 12-volt devices operated
during the charging period.
Dry camping
Consider the charge condition of the house
batteries when dry camping. If the house
batteries are not being recharged and power
is being drawn from them, they will eventually

discharge. A 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 battery will read 12.7
volts DC and 1.265 specific gravity at 80°F
(32°C). The house batteries are considered
discharged at 11.8 volts DC by electronic
standards. When voltage drops below those
levels, permanent battery 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
a
amounts of current even when turned OFF.
To prevent house battery discharge when the
RV 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 batteries.
During storage, it is important to check battery
voltage at least every two weeks and
recharge as needed. If you remove the
batteries 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 batteries, replace
with Group 27 deep cycle batteries only.
Contact the
information. Do not reverse the positive and
negative battery cables. Doing so will blow the
reverse polarity
converter.
