Since different RVers use different power setups, you would see contrasting opinions once it comes to the best RV battery. That being said, to get your money’s worth, it’s nonetheless strongly recommended that you consider the following criteria.

best rv deep cycle battery
  • Energy Capacity

Since the purpose of the battery is to power the appliances, the value of particular models could be determined through the capacity in most cases. If you often plan your trips around RV parks, campsites, rest stops and so on, feel free to settle for batteries that feature ordinary capacities. On the other hand, if you intend to go off-road with your RV now and then, you must pay attention to RV battery ratings. At all times, remember that running out of power is the last thing you want to experience on the road. 

  • Life Expectancy 

Obviously, nothing lasts forever but you should prioritize RV batteries that last a long time. With a quality long-lasting model around, you don’t have to worry about getting replacements in the near future. Of course, many factors influence the life expectancy of your battery on the field such as charging currents, temperatures, usage,… Still, if you truly hope to get the best deal available, you need to think of life expectancy as one of the top shopping criteria.  

  • Weigh And Size 

These kinds of days, batteries for RV campers come at a variety of sizes and weights which naturally require consideration. You would be able to decide what model of battery your recreational may use by carefully assessing its battery compartment. Usually, in most modern-day recreational vehicles, the battery compartment is more than capable of accommodating a few additional batteries aside from the default ones. As for the weight, having lightweight batteries facilitate overall handling, inspections, maintenance and so on.

  • Resistance 

All RV owners from novices to veterans know that in the outdoors, things could get quite rough now and then. Because of that, before virtually every purchase, RVers routinely ask themselves: is it tough enough? The same applies to the batteries of RV as you don’t want to waste your money on mediocre models. You better keep an eye for batteries that have the ability to resist shock, vibration,… Just in case, check out the customer reviews to get a general idea about the resistance of your preferred batteries.  

  • Acquisition Cost 

After embracing the RV lifestyle, it’s highly likely that you have various expenses to address at any one time. As a result, while searching around for the best RV battery, price is something that you need to think about. You definitely save some money by buying cheap batteries now but due to typically limited lifespans of such models, you actually spend more on replacements. So it’s widely advised that you refrain from purchasing dirt cheap batteries for RV. The ideal approach to price is to find the balance between performance and acquisition cost. 

Different Types Of RV Battery

On the market, you should see several types of batteries designed for RV with distinct designs, operations and so on. In order to make informed investments, it’s essential that you get to know them.

rv battery types
  • Flooded Batteries: Also known as wet-cell batteries, flooded batteries handle overcharging effectively and efficiently through the hydrogen venting process. In addition to that, batteries of the type have a relatively large power-to-ratio which makes them popular to most RVers. Just as importantly, though they indeed require constant maintenance, flooded batteries possess long life expectancies. Last but not least, thanks to the highly affordable prices, the venerable wet-cell models remain in use alongside the more modern batteries. 
  • AGM (Absorbed Glass Mat): Unlike flooded batteries, AGM batteries usually don’t demand constant maintenance.  Moreover, gas emission is less than an issue in AGM batteries so you have no need to concern yourselves with ventilation while charging them. Being tightly sealed, batteries of the type ensure that you never face spilling incidents. Because of the rugged bodies, AGM batteries tend to boast excellent resistance against vibration, temperatures,…
  • Gel: Compared to other types of batteries for RV, Gel batteries utilize strong internal constructions which give them superb endurance. On the downsides, batteries of the type employ narrow charging profiles that often gets damaged. Also, overcharging Gel batteries could lead to the formation of gas pockets on the plates. Over time, the gas pockets would steadily reduce the maximum charging capacity of the batteries. That is why you need to have experiences to put Gel batteries to good use. 

Reputable Brands of RV Batteries On The Market

Even premium-grade models from world-famous manufacturers fail to satisfy the customers on occasions. Nonetheless, if you have to buy something for your recreational vehicle, you better favor popular names over less-known ones. 

1. DieHard Batteries

3. Optima

Useful Tips to Extend the Life Of Batteries For RV

Generally speaking, automobile batteries could last for many years assuming that they receive appropriate maintenance. Unfortunately, soon after purchasing new batteries, various RVers need to find replacements again because they fail to take proper precautions. So if you don’t want to wreck your batteries by mistake and waste your hard-earned money in the process, follow the recommendations below.

  • Avoid Leaving The Batteries Depleted 

Once the charge in the batteries run low, crystals start forming on the plates, a process that is called sulfation. In case you fail to recharge the batteries in time, which lets the sulfation progress pretty much unchecked, the batteries should be ruined before long. Hence, in order to preserve the batteries, it’s of utmost importance that you perform recharge in a timely manner. If possible, get yourself a voltmeter to determine the ideal time to recharge the batteries. The rule of thumb is to keep the charge above 50% for most of the time.   

  • Don’t Forget Parasitic Loads 

Even if you turn off all the appliances in your recreational vehicle, certain things would continue to deplete the batteries such as gas leak detectors, antenna power booster, clocks, stereos,… To prevent the parasitic loads from discharging the batteries, it’s necessary that you set the battery disconnect switch to the “off” position if you don’t use the RV.

  • Check The Electrolyte Levels Periodically

Keeping the electrolyte acceptable levels is the key to extending the lifespan of RV batteries so pay attention to that. If you find the electrolyte to be low then proceed to add more distilled water. Don’t have distilled water? Well, if that is the case, mineral-free water could work as an adequate alternative. But whatever you do, refrain from adding tap water since that is going to cause calcium sulfation and kill your RV batteries in no time.

  • Consider Using Three-Stage Chargers 

If you don’t know, batteries should be best charged in three stages: bulk charge, abortion charge and float charge. The first stage brings the charge of the batteries back to 90 % then the second stage charge the remaining 10% and the third stage maintain the full charge.  The market these kinds of days offers a variety of three-stage chargers so it’s a good idea that you pick up one.

  • Only Add Water After Recharges 

Unless the plates seem to be exposed, you must add water after charging the batteries. If the electrolyte runs so low that plates of the batteries exposed, you need to add water to cover the plates first before performing recharges. By leaving the vent caps on batteries while charging, you could limit losses of water.

Keep in mind that things don’t exactly work in scale here: It may take 4 hours to take charge of the batteries from 50% to 80%. To get the charge from 80% to 90%, you sometimes have to wait for around 4 more hours. The last strength (90% to 100%) could be as long as 8 hours.
