Auxiliary Battery; Circuit Breakers And Fuses-12Volt Dc - venture Sonic series Owner's Manual

When the converter receives 120 AC power, it transfers power into
12-volt DC without any manual switches. The converter also
charges the auxiliary battery (s) when installed on the coach and is
attached to 120-volt AC power. The third function of a converter is
to send 12-volt power to the fuse panel and throughout the coach.
Each converter has a "built-in" fan which operates through a load
sensor control or temperature sensor. As more current is drawn, fan
will speed up, run faster, or slow down, based on amp draw and/or
temperature. Should the fan not run at all, the converter may
overheat and will cut-out and/or stop.
Auxiliary Battery —NOT OEM available
All travel trailers and fifth wheels are pre-built to accept a battery.
Batteries are not standard equipment on units.
Recommended batteries are of deep-cycle type as you need longer,
slow consuming power rather than cold-cranking power. A battery is
always required for a break-away switch to function.
A battery requires routine maintenance for long life. First, terminals
need to be kept clean to avoid corrosion. Second, a battery used
daily will consume water as long as the converter is in operation. Be
sure to check the battery no less than every 30 days and keep the
battery filled with distilled (rain) water. Most good deep cycle
batteries are NOT maintenance free.
A converter will not overcharge a battery unless a battery has a
dead cell, or the converter has a malfunction. Some type of
converters have full battery charge shut-off. Other types reduce the
rate of charge as battery conditions reach 12.7 volts DC or 1.265
specific gravity at 80°F. By electronic standards, a battery is
discharged at 10.5 volts. Dropping voltage lower than 10.5 volts will
begin damaging plates in the battery.
The interior lights will operate from the converter and/or auxiliary
battery. Some lights will have wall switches and other lights have
switches in the lights themselves.
