INSTALLATION MANUAL
BATTERY DISCONNECT
If your Battery Disconnect is equipped with a Voltmeter you can determine the state of charge of your battery(s).
The voltage on the battery is a reliable indication of the amount of charge in the battery when the battery is “at rest”.
The best time to read the voltage is when the battery has not been charged or discharged for several hours. The
reason for this is to allow the internal chemistry of the battery to stabilize.
If the battery has just been charged, it should be loaded to remove the “surface charge” from the plates which would
give a higher than normal reading. This can be done for the coach battery by turning on some lights in the coach for a
few minutes, or for the chassis battery by turning on the headlights for a few minutes. After any loading, disconnect
the battery with the “STORE/USE” switch and allow at least ten minutes for the voltage to stabilize. Then reconnect
the battery with the “USE/STORE” switch, press the VOLTAGE CHECK switch and read the amount of charge from
the chart below.
A charge of 50% means that a new battery could deliver one half of its rated amp-hour capacity. Since a battery
loses its ability to store charge as it ages, a two year old battery at 50% charge would not provide as much
service as a new battery of the same amp-hour rating would at 50% charge.
Batteries should be stored at least 75% charged.
Afully discharged battery can freeze at 15 degrees F.
See your RV owners manual for battery service and charging information.
A properly operating charging system should read between 14 and 15 Volts when charging. When the RV is
plugged into 120 Vac (or the gen-set is running) and the COACH battery is in the “USE” position, it is being
charged. When the RV engine is running the CHASSIS battery is being charged.
