Reasons Why Everybody Should Use a Battery Cutoff Switch.

Many adventurous campers hoping to avoid the charges of public campgrounds head out for dry camping treks into areas where they can get away, get in touch with nature, and spend some peaceful days away from the hustles of their busy lives. A lot of such campers prefer the convenience of traveling in their RVs.

The convenience of a Battery Cutoff Switch

The RV makes this trek much more convenient than a regular vehicle. The presence of an “indoor” bathroom, sleeping arrangements, storage for spare food and water, and the ability to shelter comfortably from inclement weather all score advantage points for an RV on a boondocking adventure. Where the RVs become concerning, however, is the longevity and reliability of batteries.

For this reason, many use a battery cutoff switch for RVs. When camping in an RV, you do not typically have a power source to keep your battery’s charging when you need them to be. Your RV will not be running the whole time you are using it, of course, but that doesn’t mean that there won’t be a drain on the battery.

Unless you plan on stumbling around in the dark when night falls, not using your RV radio at all, or plan on using any appliances, chances are your RV will still slowly drain your battery as you make use of things that require power.

The battery cutoff switch allows you to power down the battery use, helping to preserve it for as long as possible, and keep yourself from being stranded in the middle of a beautiful but contactless location.

How a Battery Cutoff Switch Works

When you engage the power switch, any appliances (including lights) that rely on 12 volts will only work if your RV is plugged into a power source of a shoreline. External power will not stop the RV from operation with the necessary power even with the switch. Still, if the shore power is no longer inbound, your appliances will not switch to be powered by your battery.

If you had the misfortune of leaving your overhead light or your headlights on in your car overnight, you have likely arrived at the frustrating surprise of your car not starting the next day. These things need the power to operate, and with the vehicle being off, that power comes from, and systematically drains your car battery.

At this point, you likely had to have assistance jump-starting your vehicle. But when you are residing in self-imposed nature isolation, no aid is going to be reached, nor is any help on the way.

Your battery stays alive when you run your car because the alternator is operating, and it perpetually charges your battery. Without the alternator working, any source of power relies solely on your car battery, and it has a finite lifespan.

More Practical Reasons

You should always shut off the power to your RV via the battery cutoff switch if you are doing work on your vehicle. The power should be off for a minimum of 24 hours before you attempt to begin.

As an RV is a once-in-a-while used vehicle, you are likely to be storing it more often than using it. To prevent the battery from slowly draining as appliances inside, being unused, continue to draw power slowly. Left powered on, some piece of equipment may end up overheating, causing an electrical fire.

All this can be prevented by simply cutting the power off to unused devices. For a vehicle the size of an RV, this drain, even when slow, will not take long to drain the battery rendering it useless.

Cutting off the power with a battery cutoff switch can also help prevent vehicle theft. As the RV can’t run being fed power, any aspiring thief looking to borrow your RV permanently will run into a problem with trying to start it.

Maintaining your RV batteries will save money by preventing the need to be jumped and extending the longevity of your battery’s life for as long as or longer than a decade.  You might be interested in “How do I choose an RV Battery“.
