Section 6: Electrical System
Auxiliary Battery (Customer Supplied)
The combined 12-volt DC loads in your recreation vehicle can become more than the power
converter is able to produce. This demand can be met by using an auxiliary battery for a
limited period of time. The 12-volt system is designed for usage with a Group 27 or 31, deep
cycle battery.
Dry camping
The auxiliary battery should be fully charged prior to dry camping. If the auxiliary battery
is not being recharged and power is being drawn from it, it will eventually discharge. Plan
your electrical usage accordingly. You can test the auxiliary battery voltage using a volt-ohm
meter (customer supplied).
A fully charged lead acid or AGM auxiliary battery will read 12.7 volts DC and 1.265 spe-
cific gravity at 80°F (32°C). The auxiliary battery is considered discharged at 10.89 volts,
and dead at 10.65 volts. If the voltage drops below those levels, irreversible damage can
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, or any other 12-
volt component. If the furnace and refrigerator in this example operated constantly, a 75
amp-hour battery would become fully discharged in 5 hours.
The auxiliary battery should be installed in parallel with the battery in your tow vehicle.
When the 7-way trailer plug is connected, both batteries power the RV. Do not allow it to
discharge your tow vehicle battery below the level required to start the engine. To prevent
this from occurring, disconnect the 7-way trailer plug or install a battery isolator. When the
tow vehicle engine is operating with the RV connected, the tow vehicle charging system will
charge both batteries.
Replacement and maintenance
Some equipment in your RV will draw small amounts of current even when turned OFF. To
prevent the auxiliary battery from being discharged when your RV is not connected to shore
line power, disconnect the auxiliary battery negative cable at the battery. During storage, it is
Do not store anything inside the battery compartment(s)
or near the
batteries that could touch the battery or battery cable terminals. Contact
with the battery or battery cable terminals could cause an electrical short
circuit, discharge the batteries, or start an electrical fire.
Keep sparks, cigarettes and flames away from the batteries as the
hydrogen gas they create may explode.
Do not connect a booster bat-
tery or other power source that outputs more than 14.2-volts DC to lead
acid or AGM batteries. Use adequate ventilation when charging or using
batteries in an enclosed space. Remove metal jewelry and always wear
eye protection when working around batteries.
Do not allow battery electrolyte (acid) to come into contact with
skin, eyes, fabric or painted surfaces.
Electrolyte is a sulfuric acid so-
lution that could cause serious personal injury or property damage. If
your hands, eyes, clothes or the painted surface of your motor home are
exposed to electrolyte, flush the exposed area thoroughly with water. If
electrolyte gets in your eyes, immediately flush them thoroughly with
water and get prompt medical attention
