Contributing expert Mark Polk from RV Education 101 shares his knowledge about RV batteries. It’s easy to forget about your battery and not give it much thought until something goes wrong. Watch this video and potentially avoid future problems.
If your travel trailer didn’t come with a battery shut-off switch, it’s important to install one so you can shut off power when in storage. If you don’t do this, the battery gets completely drained from all the little lights, etc. inside, which is hard on the battery. Some people install the shut off switch on the front of the trailer where the battery(ies) is, and some prefer to install it inside near the breaker bank, protected from the weather.
