RV Battery Types: An Overview of Your Options

Duration: 2:18

Based on the amount of boondocking you do and the types of appliances you utilize on your RV, there’s a certain type of RV battery that’s optimal for your needs. While some RVers spend little time at their campsite and rely upon only minimally power-thirsty appliances, others require heavy duty batteries that they can hook up and forget about until they’re back home.

Thus, in this lesson RVing expert Dave Solberg talks about the various RV battery types you can purchase for your home away from home. He first explains which option you might opt for if you don’t mind regular maintenance and need only a small amount of juice, then talks about the upscale choice geared toward those who prefer minimal upkeep and have spare change to spend on something that will go the distance. Whatever your power needs, Dave can help you find the one that’s best suited for your specific needs!

      I also have Lithium (DragonFly DF10012) and would be interested in your thoughts on these batteries.

        Hello Wayne,

        I am not familiar with the Dragon Fly brand of batteries and most major brand of RV manufacturers are not offering them. Lithium Ion batteries are probably the future of batteries, however they are very expensive and only needed if you do a lot of dry camping. If you properly charge your lead acid batteries with a multistage charge, they will perform well for most applications at a fraction of the cost. However most converters do not have the multistage and therefore they sulfate and lose energy storage capabilities and get blamed for being bad batteries.

        Thanks,

          Actually, over the projected much longer lifespan, and given you can fully discharge rather than only 1/2 with lead acid, and the lower weight, Lithium batteries are more cost effective, save weight, last longer, so sulphuric acid. How old is this video that they don’t even get a mention?

      Hello Jose,

      Thanks for this wonderful question!  This is a big misconception in the industry that just going to AGM gives you more power.  This is not true as both batteries will be connected in series (positive to negative) which give you a 12-volt battery bank.  Both lead acid and absorbed glass mat (AGM) are sold in the exact same amp hour ratings or groups such as group 24, 27 etc.  However the AGM is superior as it requires less maintenance and is not prone to as much sulfation so it hold more capacity.  Lead acid batteries require a monthly multistage charging which most RV charging systems do not have so they start to sulfate and have less storage capacity.  If you have an inverter with a multistage charger or the Battery Minder, the lead acid will perform as well.

      Thanks,

    I build van life Van’s. I have always recommended li_ion batteries as a solution for hi draw builds. Li-on batteries have 8 to 10 times more life than AGM batteries and will accept larger charge and discharge rates. In the long run they are actually a better choice for the long run. BTW, dragonfly is the retail product for Battle Born batteries. Fo some research and check out their site.

    Could anyone tell me if I were to get a 12 volt or max cap battery to change out my 2 6 volts difficult to do?

      Julianne,

      The replacement would be easy, just the connections will be a little different. 6v batteries need to be connected in series where as 12v batteries need to be connected in parallel. I can provide a diagram on how they need to be connected to the system if you need it! The easiest thing to remember is that when connecting anything 12v together all positive connections are connected to positive and then all negative are connected to the negatives. There is no cross connections. I hope this helps!

    Can you explain multistage charging and what is a Battery Minder? Can you suggest an inverter that will accomplish this multistage charging to extend battery life?

      Most newer converters these days do offer multi stage charging. You can look up your model online and see if it does offer it before buying a new one. The three stages would be bulk absorption and float. Bulk is what charges around 80 percent of the battery. It then goes into absorption which has a higher voltage charge to make sure the battery absorbs as much as possible. Once that is complete it goes into a float stage, which is a trickle charge to help maintain a good fully charged battery. A lot of people with older systems just get a Battery Minder to use when plugged in for storage as it is better for the batteries than the house charging system. Newer systems work just as fine so it is best to look up the model you currently have and see how it charges. Minders are great to use when taking off of the unit and storing indoors. I only recommend onboard use if you have an older converter that doesn’t charge well.

    I want to replace the lead-acid battery with a lithium battery My 2021 Jayco Greyhawk 30Z came with a Progressive Dynamics Intelli-power 9100 converter for the lead-acid. I need to replace that with an Intelli-power 9100L for the lithium. Where is the converter located?

      Usually the converter is located directly behind the main power distribution center. You typically have to pull out the center if there is no other access behind it. The converter connects directly to the fuse panel in the distribution center so the best thing to do is trace the wires to the fuse panel and see where they go. Typically it is directly behind the center but could be in a cabinet or compartment nearby.
