Best 6v RV Battery Buyer’s Guide

best-6-volt-battery-for-rv

Choosing the best 6v RV batteries will come down to several factors for a rig owner. This section will discuss each of them to make sure you can make a smart final decision. I want to ensure your chosen options will have no trouble meeting your needs.

  • Battery Capacity

An RV 6V batteries capacity will be rated or measured in Ah, which stands for amperage hours or amp-hours. It indicates the amount of current a battery is capable of providing over a determined time frame.

In other words, a 100Ah capacity battery could deliver 100A for an hour. Rig owners should be looking to buy a 6V battery with a high-capacity. It’s a crucial piece because it ensures the device can store more energy and have a longer lifespan.

In addition, it’s essential to pay attention to the battery’s size and weight, as well. These two factors are pivotal because there’s limited storing space onboard your rig. As a result, you’ll need to make sure you have enough available room for these incoming batteries.

Figuring your rig’s ideal capacity won’t be too difficult. The process begins by figuring out your rig’s specific energy requirements. Make some adjustments to the total by adding a little wiggle room and determine how much power you use daily.

It would be best to choose a battery that can supply the right amount of power without going down to 50% or 60% of its allotted capacity. It’s also worth noting you can recharge these batteries via solar power, a generator, or campground electrical hookups.

But boondockers or off-grid RVers should look into buying a 6v battery capable of supplying your power needs without depleting. It’ll make sure you can go for several days without any recharge, which is perfect for these rig owners.

  • Discharge Depth

One of the most important factors would have to be a battery’s discharge depth. Brands will convey these measurements in a percentage that determines how power gets discharged by each battery.

If you’re buying lead-acid batteries, it’s vital to note their discharge depth and life cycle correspond. For instance, models with deeper individual cycles will have a shorter lifespan and provide fewer cycles.

I’d end up advising to look for a deep cycle 6V battery with a discharge depth that can maximize its life cycle. Customer reviews should provide some insight into this factor. After all, buyers tend to get angry when their batteries don’t meet their expectations.

  • Operating Temperature Range

Rig owners tend to overlook whether a battery can provide power in both high and low temperatures. But it’s a factor that every buyer needs to invest some time into thinking about when choosing a 6V battery for RV usage.

For instance, full-time rig owners will need an option to work in low temperatures to ensure they are usable during the winter. This ability will ensure you don’t find yourself in a 0-degree environment without access to a functioning battery.

Manufacturers will make finding out this information relatively easy by placing it in their product descriptions. But these batteries will need to be compatible for usage in high-temperature settings, as well. Cold weather functionality isn’t enough when choosing your perfect model.

In other words, this battery will need to be built for working in hot, humid areas. It would be ideal to check the product can sustain a temperature of at least 35 degrees. This ability should ensure they have no problem working in cold or hot environments.

  • Construction Quality

Buyers will want to buy 6V batteries with a reputation for offering extreme durability and longer lifespans. You’ll need an option with a reliable, sturdy construction that can withstand those bumpy terrains on a camping trip.

Any top-tier model will need to offer resistance against both vibrations and shocks. It’s the only way to ensure the battery can handle RVing without falling apart. Otherwise, you might end up spending a great deal of money on repairs, which isn’t something anyone wants.

RV Battery FAQs

This FAQ section will answer and cover any topics not discussed in our product reviews or buying guide. These discussions will make sure you become a person who can choose the perfect 6V battery without any trouble.

Who is this for?

6v batteries for RV usage are actually known as golf cart batteries because they have thicker plates inside them than a 12V deep cycle battery. This aspect ensures they’re capable of providing more long term energy and sustaining deep recharging/recharging.

As a result, these abilities make them ideal for people looking to camp away from civilization. In other words, boondockers and off-grid rig owners tend to favor these batteries. It ensures they don’t need to camp near or with something capable of recharging them.

What are the different types of 6v RV battery?

As you might imagine, 6v RV batteries do come in various types. I’ll discuss each of them below to ensure you know what kind would fit your needs. This information should help lessen the number of available choices to a more manageable selection.

Flooded Lead-acid 6v Batteries

Flooded Lead-acid 6v batteries are the most common 6v battery used in rigs today. You can expect these options to consist of lead-oxide and lead plates, which have an electrolyte surrounding them.

These flooded batteries effectively handle overcharging through the hydrogen venting process. You should also anticipate them to have a large power-to-ratio, which is one of the many reasons for their popularity among rig owners.

But it’s vital to realize flooded lead-acid types need constant care maintenance. It’ll require a user to keep up with watering, terminals cleanliness, and equalizing charges. An hour annually of care should be more than enough to keep them in good shape.

I should also mention that these batteries tend to have affordable prices. This advantage has kept them a popular commodity even with more advanced types available. People looking for a simple and effective option will be more than happy with a flooded lead-acid 6v battery.

AGM (Absorbed Glass Mat) 6v Batteries

One of the more versatile types would have to be AGM 6v batteries. These options aren’t only compatible with motorhomes usage but also work well in boats, trucks, and trolling motors. You can also expect them to be a bit tougher than a flooded lead-acid option.

This toughness comes from them having a lower internal resistance, capable of working in high temperatures. Additionally, AGM batteries are known for having a slower self-discharge rate than other types.

Rig owners won’t have to worry about constant maintenance with these batteries, either. This benefit comes from them not being susceptible to sulfation like flooded lead-acid options. Therefore, you can store them for a long time without worrying about damage occurring.

Gas or hydrogen emission tends to be less of an issue in these batteries, too, which means ventilation isn’t necessary when charging them. Their tightly sealed constructions also prevent spills from being a problem.

Overall, these options tend to be a perfect fit for RV usage. But their many positive features come with a high price tag. You’ll have to decide whether the lack of maintenance and top-tier performance quality is worth the extra money.

Gel 6V Batteries

Buyers will note that gel batteries will offer some of the same benefits as flooded lead-acid types, like being easy to transport. The only difference between the two is these options come with highly sticky gelled electrolyte.

Gel batteries also have strong internal constructions to ensure they can offer superior durability than other types. But there are few downsides to these options, such as charging it too much can cause gas pocket formation on the battery’s plates.

This issue will decrease its overall capacity and force the electrolyte away from these plates. As a result, the gas pockets will continue to reduce their maximum charging capacity over time. Gel options also have narrow charging profiles, which is why they tend to get damaged easily.

Lithium-ion 6v Batteries

Our last type tends to be a favorite among campers who value top-tier performance over everything else. For instance, these batteries feature highly sustainable voltage levels to make it possible for them to deliver up to 99% usable capacity: flooded lead-acid or AGM batteries only offer about 50%.

This ability makes them a perfect fit for extended boondocking or dry camping. Users will also benefit from them, offering an impressive charging efficiency of up to 5000 life cycles. It ensures they’re a rather convenient and effective option for rig owners.

Gel batteries offer superior performance when it comes to extreme temperature conditions, as well. You can attribute this ability to features like its built-in safety measure against overheating. Once it does overheat, these types will automatically shut down to prevent a dangerous situation.

These options don’t falter against extremely low temperatures, either. Cold weather RVers shouldn’t worry one bit about them not performing well on those frigid nights. A few other useful attributes include versatile mounting capabilities and stable energy flow in any direction during usage.

How does a 6v RV battery work?

Understanding how 6v RV batteries work within a rig is essential. The first thing to understand is there are two primary ways of wiring these devices, in a series or parallel. Connecting 6v batteries via a series will increase the system’s voltage but keep the amp hours consistent.

The process of connecting them in a series includes attaching the first battery’s negative terminal with the second battery’s positive counterpart. You then use an additional set of cables to connect the open negative and positive terminals to your rig.

Once they’re set up, these two 6v batteries will be in series capable of providing 12 volts of power. But it’ll only charge to your battery’s capacity with the lowest Ah capacity. Meanwhile, two 6v RV batteries connected in parallel will increase your current, but the voltage will remain the same.

This process will consist of connecting both positive terminals and another jumper wire to each battery’s negative terminals (positive to positive and negative to negative). Once they’re assembled, their combined voltage will stay at six volts. But their Ah capacity will equal the total sum of the connected batteries.

As a result, motorhome owners will first need to wire two 6v batteries in a series to create a 12v battery. You can then wire these batteries to another pair of 6v batteries using parallel. It’s an effective way to increase the total Ah capacity.

Advantages and disadvantages of using a 6v RV battery

Several benefits come from having your rig using two 6v batteries connected in a series. But there are some disadvantages to having this setup, as well. Here’s a quick rundown of what makes this configuration better and worse than having a single 12v battery:

Advantages

  • Larger Ah capacities
  • Bigger discharge and recharge capacities
  • Proper maintenance can ensure them last long

Disadvantages

  • More expensive
  • Much taller and could require installing different battery boxes
  • Harder to find (only found at specialty or large automotive supply stores).

How many years do 6 volt RV batteries last?

If you take care of them, 6v batteries can last anywhere between 4 and 8 years. It makes them more reliable than 12v batteries that tend to have a shorter lifespan. 12v batteries often will need replacing after only two years.

Are 6 volt RV batteries better than 12 volt?

There isn’t a simple answer because it’s more of a preference issue. For instance, some rig owners prefer using 6v batteries because they offer higher Ah capabilities and last longer. But other RVers love using a 12v battery because they’re much more convenient and cost less.

In the end, each buyer will have to decide what configuration fits best into their needs. You’ll have to weigh the advantages of each one and decide what aligns with your preferences.

Does 6 volt RV battery charge driving?

Your 6v RV battery will receive a charge via the engine’s alternator when you’re driving. You can also run a generator while traveling. But a properly sized alternator should keep these batteries effectively charged without issue.

How to install?

Installing two 6v RV batteries can be done by following four simple steps. If you don’t feel comfortable doing this type of electrical work, I will always suggest hiring an expert. But people who do should continue and start with step 1:

  • Wire two 6v batteries in a series to produce a 12v battery
  • Connect its load to the positive battery terminal to the negative terminal of another.
  • Ground the negative terminal of the cell
  • The connections are complete

How to use?

Once your two RV 6v batteries are installed, there’s nothing left to do. These batteries will work and do their respective jobs until they can’t. The rig owner’s job now becomes staying up-to-date on the care and maintenance of these batteries.

Any care and maintenance tips?

Caring for and maintaining a 6v RV battery is a pivotal piece in making sure it meets your expectations. The process of keeping them in good shape will differ from model to model. It’s the reason why reading your chosen option’s manual is critical for any rig owner.

However, there are some essential tips for keeping them useful. Here’s a quick list of what a rig owner can do to ensure their batteries remain functional:

  • Maintain electrolyte levels in flooded-cell 6v batteries: Flooded-cell batteries will lose water with each charge cycle. You’ll need to replenish this water for performance purposes. It’s necessary to use distilled water, which will help prevent sulfation from occurring.
  • Keep the battery terminals clean of any built-up corrosion: I’d recommend using a mixture made up of one cup baking soda and a gallon of water or a commercial battery contact cleaning product. In either case, a toothbrush would be the best tool to use for the scrubbing.
  • Never let your batteries get too low in charge: If you allow the batteries to get under 80%, the sulfation process can begin. This issue is why recharging your batteries soon after usage is necessary.
  • Recharge them often: But it’s vital to understand overcharging and hot temperatures can have lasting adverse effects on their performance.

Conclusion

After reading this article, finding the best 6v RV battery shouldn’t be much of an issue. It’s a simple matter of using what I’ve laid out during your search. The process should become relatively straightforward in a quick manner.

But some more questions might come up during this process. If you have one, please leave a post in our comment section. I’ll make sure to answer them as quickly as possible.
