Typically, Batteries are a perfect solution to our energy needs that can give you a mess if not properly used or taken care of them. We use batteries for many purposes, from the simple requirement to advance requirement. However, batteries are one of the essential requirements of RVs too. Especially if you intend to do some boondocking, trip, or dry camping, or it is crucial to have the perfect, suitable, and efficient  RV batteries with you to enjoy a great experience without issues. Therefore, knowing the RV batteries, knowledge to pick the best RV battery, and understanding their usage is necessary for a regular camper.

Therefore, the batteries or batteries used to supply the RV are called RV batteries. Mostly Batteries or battery used supplying the RV itself with 12-volts are also known as house batteries. These are Lead-acid batteries are batteries in use in RVs, which means they have several cells connected in sequence. Each cell generates about 2.1 volts, so a 12-volt battery with six cells in series generates a 12.6-volt output voltage. In this procedure, starting batteries and marine batteries are not used. Many RVs have various kinds of RV batteries that they use to power all from your mobile home engine to the lighting lamps in your coach. Below are some of the best and popular RV batteries across the world:

  • Universal Power Group Deep Cycle AGM Battery.
  • Odyssey PC680 Battery.
  • VMAX Deep Cycle HI Performance Battery. 
  • Universal Power Group Sealed Lead Acid Battery.
  • DieHard 38217 Advanced Gold AGM Battery.
  • VMAX Solar Deep Cycle Battery. 
  • Optima Deep Cycle Marine Battery. 
  • Renogy Rechargeable Deep Cycle Pure Gel Battery
  • Battle Born Batteries Deep Cycle Batteries
  • ExpertPower Rechargeable Deep Cycle Battery.

What is the importance of RV batteries?

Batteries are an efficient and proper source to generate power.  For example, batteries in your wall clock generate power for the clock; a car battery generates power to start the engine. As per that, RV batteries generate power for your electronic accessories while your engine is not working or camping dry for an extended period.

Without a properly working 12-volt DC home battery system, most stuff inside your RV will not operate. It would help if you had good batteries and a way to charge them for your 12-volt DC home battery system to work. That is where the power converter for your RV is used. Furthermore, without properly working starting batteries, it is unable to power the motor of your RV.

What are RV house batteries?

House batteries should be deep cycle batteries built over a long period to provide a steady current amount. To help power devices such as water pumps, fans, TVs, lights, and other RV appliances, all motorhomes, and towable RVs have house batteries.

You may have 12-volt batteries or 6-volt batteries mounted in pairs based on your RV size, such that their combined voltage is 12. House batteries come in three distinct types: wet batteries, gel batteries, and dry batteries tend to be deep cycle batteries. For a long time, deep cycle batteries provide a steady amount of energy, which works well in your RV for running appliances and other electrical products. Below are the types of deep cycle batteries:

  • Conventional Flooded Electrolyte

The most typical form of battery. OE that comes with the new RV, usually. Occasional maintenance involves testing the level of water and, if necessary, refilling this with distilled water. Corrosion from terminals needs to be washed more regularly—strong ability at cost-effective prices. Fast charging, Hot weather, batteries used often would require more frequent refilling of water.

  • Gel batteries

Gel batteries are more costly than standard flooded electrolytes, but last longer and need no maintenance. The downside is that fast charging as well as flooded electrolyte batteries are not tolerated. Absorbed Glass Mat (AGM) AGM batteries last longer and cost more than conventional batteries, much like gel batteries. They handle marginally better quick charging than Gel.

What Are RV Chassis Batteries Or Starting Batteries?

Chassis batteries commonly referred to as starting batteries, power the motor of your RV. Apart from deep-cycle batteries, for shorter periods, chassis batteries need to produce high energy bursts. These are the same battery types used in the vehicle; however, most chassis batteries have a higher CCA (Cold Cranking Amps) rating to fit the larger RV engine.

What are Marine Batteries?

Marine batteries are an effort to create a compromise design that incorporates starting and deep cycling characteristics. They aren’t perfect for either need, as with most compromises. Still, they might be appropriate for certain RV battery situations, a marine battery trades for a somewhat better deep cycle output with a lower CCA ranking. The main benefit is that it is a variant of a starting battery and can be produced. The same production method makes it a less costly battery than a true deep cycle.

What is the difference between RV Batteries and Car batteries?

Most of the people confused about the RV Batteries and Car batteries. Both of the car batteries and RV batteries are lead-acid batteries. This implies they have multiple cells connected in a series that contain 2.1 volts. These batteries consist of lead and lead oxide plates, which are submerged in an electrolyte material formed of water and sulphuric acid. The size and volume of electrolyte of the plates define the charge that can be stored by a battery. These batteries do not generate power, they simply store it.

Still, RV batteries are “deep cycle” batteries, which generate a steady amount of current and can be discharged and recharged again over a long period of time. For a short period of time, a car battery is produced to generate a large amount of current.

How do you maintain RV batteries?

RV batteries maintenance is not a single activity, and it is a collaboration of several essential activities. camping battery maintenance is not a single activity, and it is a collaboration of several essential activities. RV batteries Maintenance includes test-cranking amps/volts, topping off battery fluid,  applying anti-corrosive spray-on battery posts, and you have to keep proper care in cleaning, storing RV batteries. If there will be some issues or any exceptional advice for you, you can get serviced by professional expertise.

  • How to clean RV batteries properly?

Prevention is always better than cure, and it is also to apply in the RV battery Maintenance. Therefore regularly cleaning your batteries is an essential requirement for proper maintenance. So, never wait until your battery is covered in corrosive deposits to clean it.

It is important to clean the battery terminal connections, along with the clamps that attach to them. You can use a wire brush or just a toothbrush with a baking soda and warm water mixture to neutralize the corrosion. While cleaning your RV battery, don’t forget about your safety. Begin by wearing old clothes or proper safety clothes and protective gloves for appropriate protection of skin. Wear goggles for eye protection because a drop of battery acid can cause real harm to you.

  • How to Store RV batteries properly?

It is essential to store your RV battery properly in the right conditions to prolong your RV battery’s life and get the most out of your investment. Most significantly, a battery must never be stored in a discharged state, or the battery plates would start to harden and crystallize, finally allowing them to be no longer able to produce electricity.

Both house batteries and chassis batteries required regularly charging, but keeping house batteries charged is particularly necessary, as sulfate tends to gather between charges on the plates. A new charge can no longer eliminate the sulfates until too much sulfate is accumulated, leading to a dead battery. Many inverter systems have an equalization feature that helps to mitigate this when done periodically.

Making sure your batteries never go below a 50 % charge is a good rule of thumb. The benefit of batteries with lead acid is that they can be recharged again and again and again. When not in use every day, batteries naturally discharge. As a practice guideline, don’t forget to charge your stored battery every 3 months to ensure that the battery is fit enough for the next time you expect to be used. With that said, battery acid is extremely harmful, so you must wear rubber gloves and eye protection while working around your RV battery.


However, selecting the perfect RV battery or Batteries is essential for the trouble-free journey. There are many things you should consider before choosing perfect the RV battery. Type of the RV battery, Type of the RV, Budget, power, Amp-Hour, and Reserve Capacity ratings, life-expectancy, required care and maintenance, model, and price are among the primary and essential things you should consider before purchase RV battery or Batteries. Apart from that, maintenance with proper care will save your time, cost, and expand RV batteries’ lifetime. Therefore select the suitable and most efficient one and enjoy your journey or camping without power losses and unnecessary issues.
