FAQs (Frequently Asked Questions)

Do the RV batteries charge when plugged into shore power?

Yes, under a couple of conditions.

The first is simple: is the battery disconnect switch (usually located very close to the battery, either in a compartment or next to the battery) set to “off?” If the disconnect is off, then no amount of head scratching will help the batteries take a charge. Until you turn the disconnect switch, that is. You’d be amazed at how often RVs get brought in to dealerships for this simple problem. Frequently the issue is that the RV owners are new or didn’t even realize there was an in-line disconnect that needed to be considered. 

Next: is your RV receiving enough shore power to handle all of the power requirements and still have enough left over to charge the batteries?

For example, suppose you have a small 1500 Watt generator running your RV, and the air conditioning is cranked up in August while your niece is using a hairdryer for an hour. In that case, there isn’t enough power left over for the converter to send to the batteries.

Luckily, the converters we have nowadays are automatic. It takes no effort on your part to redirect power to the batteries when there is a break in power draw.

Will an RV converter work without a battery?

This one is still a hotly debated topic online. The easiest way to find out is to plug your RV into shore power, turn on some lights, water pumps, and other twelve-volt systems and then turn off the battery disconnect switch that we mentioned earlier.

What you’ll find is that nearly everything still works fine. So no, you don’t need to have a battery installed to use most of your 12V systems.

There is a caveat to that statement: motors with extremely high 12V current demands, such as slide-outs, don’t always function without a battery being installed. The reason is that some motors require more current than a typical power convert can deliver at once. The battery, on the other hand, is designed to output power in a larger dose.

Plenty of RV slide-outs can function without a battery. If yours can’t, it will typically be listed in the documentation that came with your rig or even via a sticker somewhere near the switch to operate the slide-outs.

How to Properly Use an RV Battery Disconnect Switch

Also known as: What is this thing, and when should I use it?

An RV battery disconnect switch is an essential feature for any vehicle with a house battery. Performing a single action (usually a twist) allows you to easily and quickly disconnect the main RV circuit from the battery, protecting not only the battery but also other electrical components of your RV.

This switch is typically located in close proximity to the battery itself, either in its compartment or in a nearby maintenance bay. This switch is often overlooked or even forgotten, buried behind stacks of gear inside a storage bay. 

Batteries have the unfortunate tendency to slowly discharge over time, even if the appliances they’re attached to are turned off. While turned off, electrical appliances still draw tiny amounts of energy passively in preparation for startups. Wiring itself also drains power slowly. This type of energy loss drains at least some charge from your battery and can ultimately result in a dead battery precisely when you don’t expect (or need) it.

When to use an RV battery disconnect

Understanding when to use an RV battery disconnect is necessary if you own an RV. When dealing with electronics, you should always take the necessary safety precautions, so you don’t cause any damage or risk injury.
