How do I keep my RV batteries from running down?

Install a Battery Disconnect Switch

If your coach does not have a battery disconnect switch you should install one. These switches go on the house battery and disconnect it from all the house accessories. You can buy them at any RV store and most auto parts stores. Get a good high quality switch that can handle the max current draw of your RV. When you are not using the RV use the switch to disconnect the battery and prevent it from being drained.
