How to take care of your RV battery

Written by Kimberly

Your RV is one of your most prized possessions, and its lithium battery is what keeps it alive. Therefore, it goes without saying that you want to keep your RV’s battery working at its best. However, few people know very much about RV batteries: What they do, how to use them, and how to take care of them. To help you maintain your RV’s battery, here are three things to keep in mind when using your RV.

Keep Your Battery Charged

The first rule of battery maintenance is to not let your lithium battery charge get below fifty percent. Continually recharge your battery so that it does not become damaged from under charging. If your battery life gets lower than twenty percent, you’re really going to start seeing problems with your battery’s performance. To keep your battery life from draining below the recommended charge, unplug all electronics in your RV when not in use. Even if they are not turned on, they can still drain small amounts of power. Also, when your RV is stored away, check the battery once a month and see if it needs to be recharged. Stay on top of this, and your battery could last you around seven years.

Don’t Let Your Lithium Battery Freeze

Because most people store away their RVs during winter, that’s the time of the year when batteries take the most damage. If your battery freezes, its cells will die, crippling it quickly. If you can, take your battery inside with you. A great time to do this is when you’re doing your RV’s final post-vacation clean of the season.

If you can’t, follow step one and make sure it’s fully charged; fully charged batteries don’t freeze until -76 degrees Fahrenheit. Instead of putting your RV in storage, considering renting it out instead to earn some cash!

Avoid Burning Your Battery Out

When batteries work too hard or you overcharge them, parts of them can fry and break down. There are a number of ways to avoid this problem, though. Firstly, you should invest in a 3-stage charger. Your RV probably came with a RV Converter/Charger, or 1-stage charger, while a 3-stage charger charges your battery in, you guessed it, 3 stages. This will keep your battery’s electrolyte supply from boiling out during charging. Something else you should try is connecting two or more ‘deep cycling’ batteries (batteries designed to give steady amounts of energy over a long period of time) together to store more charge. Some of the best RV deep cycling batteries to look into are the Optima 8016-103 D34M, the Odyssey PC680 and the Universal UB121000-45978. Linking lithium batteries together is a great way to get the most out of your batteries without overworking them.

Owning an RV is a lot of work, but it’s definitely worth it. As long as you know how to maintain it, it can bring you more enjoyment than anything else you own. For more information, visit us at today.
