Simple RV Battery Maintenance to Keep Them Going Longer
Your RV batteries have two jobs: The automotive battery to start and run the RV engine when you’re on the road, and the Deep Cycle house batteries to run the lights and appliances when you’re using your RV as a home instead of as a vehicle. In both cases, it’s clear just how important the batteries are to your RV life enjoyment. Keep up with RV battery maintenance is the simplest way to make sure you have power to make your coffee every morning, while still being able to start the motor and get you on the road when it’s time to move on.
Like many maintenance jobs, RV battery maintenance may seem like a thankless job that really isn’t needed as often as recommended, but this is one case where you get what you pay for, so to speak. Batteries terminals and connections can corrode in a matter of weeks, and a corroded connection reduces the recharging capabilities of your batteries. When batteries sit in an uncharged state they will not only provide less power, they begin to sulfate. Sulfation is the number one killer of RV batteries.
In this video, you’ll learn the simple techniques for doing a basic RV battery maintenance session. You’ll see how to remove loose corrosion powder from the outside of the battery, and what corroded posts look like when they need care. Find out what comes in a battery maintenance kit and why you need to have every item in there. You’ll see safety tips on the correct way to remove and attach battery cables, as well as hints on preventing damage from battery acid splashes. From visual inspections to using battery post protector, you’ll learn all the steps to RV battery maintenance here.Watch Now >>

I need to run a Cpap with humidifier all night Need to replace my batteries-2 original in motor home. They won’t last thru night anymore. Any recommendations?
If you are operating both of those machines off of the 120v system that is powered from the batteries using an inverter you will have to at least double the battery capacity to handle that. When powering things like that it is best to use a generator. Using batteries to power 120v items doesn’t last long. You can always increase your battery bank but you would also have to make sure it fully charges the next day if you plan on using it again at night. The best thing to do is use a generator, not only will it power the 120v system but it will also charge your batteries as well.

1. If you need replacement batteries due to age of the equipment, you might consider upgrading to Lithium cells, but you’ll also need to make sure your converter/charger is right for Lithium batteries.
2. Consider getting a 12v travel CPAP. This eliminates the 12v DC to 110v AC inverter losses. It takes a good amount of power to convert 12v DC to 110v AC. So a 12v DC CPAP will save you that much in conversion losses. It’s also a dirty little secret that MANY home electronics actually run on 12 volts DC, but because it’s used in the home, they have a 110 cord, and step-down transformers and diodes to convert it to 12v power internally.
would have liked for you to discuss how exactly to calculate some of the appliances you mentioned against the life of the batteries while boondocking.
You forgot to mention the furnace.
