What to Think About Before Purchasing a 12-Volt RV Battery

The purchase of an RV battery for dry camping is equivalent to beginning a very significant relationship.

RV batteries experience a variety of demands during the duration of their charging.

They run the best camping gear as well as anything from furnace fans to water heater pumps.

They are used to power in-coach refrigerators and tiny electric heaters in certain higher-end RVs.

It pays to get a good set of batteries for your camper or fifth-wheel if you plan to do a lot of dry camping.

Camping Customs

What is your furnace use frequency? You’ll probably use your furnace all night long if you camp somewhere where it gets chilly at night, like scattered campsites in the Rocky Mountains.

Additionally, even though the furnace is probably a propane-powered device, the blower that forces hot air inside the coach is electric.


Think about how often you may need hot water or utilize the RV’s plumbing system.

The majority of water heaters are gas-fired, however some come with a hybrid electric-gas system.

In any case, the plumbing system (including the water heater’s) water pumps that draw water from the fresh-water tank are electric.

When dry camping, propane may be your main fuel source, but your batteries and their stressed electrical storage capacity should keep the whole system running well.

Amount of campers

Since you’re a solitary camper, you probably won’t require high-rated RV batteries if you can keep warm at night by bundling up or don’t need a daily shower.

But if you camp with others, especially children, it will probably be worthwhile in the long run to spend the extra money on a good set of batteries to power your vehicle.

This battery is light-years ahead of my old lead-acid deep cycles. I live off-grid. My cabin is powered by solar panels and batteries. I bought this AmpereTime 300 amp-hour LiFePO4 battery to run a small refrigerator here. It is a game-changer compared to my old batteries. I’ve run it for over a month now with no issues at all. I no longer wake up in the morning, worrying if my refrigerator ran out of power overnight – especially on a warm summer night when it’s been working more than usual. Plenty of power for my needs, even after a few cloudy days.

This is my first LiFePO4 battery. It’s certainly not my last. I will be purchasing more from Ampere Time, as their price and quality cannot be beat. Also – They communicated with me from the time I ordered, until the time I received my battery. I also know they’ll be there should I have any issues. Top-notch, A1 service and product! Thank you, Ampere Time!

How To Buy The Best RV Batteries In 2023

The decision of an RV battery for boondocking may rapidly become complex.

In terms of features, capabilities, and shelf life, there may be a lot to pick through.

The most important information for purchasers of RV batteries will be provided in this part to help you make a more informed decision.


You will mostly encounter two sorts of RV battery voltages throughout your search.

They are the 6-volt and 12-volt batteries, respectively.

6V (Volt)

Generally speaking, 6-volt batteries have thicker plates than 12-volt batteries.

This implies that they also often endure longer.

RV boondockers may find them to be a desirable option because to their extended lifespan and propensity to be affordable.

If you use a 6-volt battery, you may always connect several batteries in series to increase your total charge or amperage capacity.

12V (Volt)

On the whole, 12-volt batteries are less expensive than the majority of 6-volt batteries.

Despite having this as their main benefit, 12-volt batteries are not as reliable for boondocking as their 6-volt equivalents.

They don’t keep a charge for as long, which is mostly to blame.

They also don’t go through the typical 6-volt battery depletion and recharge cycles.

Various RV Battery Types

You’ll also come across four distinct kinds of RV batteries throughout your search.

They are gel batteries, lithium-ion batteries, lead-acid batteries, and Absorbed Glass Mat (AGM) batteries.

#1. Lithium-Ion Batteries

Lead plates or grids are used to construct this kind of battery, and they are submerged in a liquid electrolyte.

These batteries are often affordable, dependable, and overcharging-tolerant.

Additionally, if kept without liquid electrolyte, they may be placed on a float or trickle charge for extended periods of time, provide high voltages, and have an endless shelf life.

The drawback of this battery type is that it is often huge and hefty.

Additionally, they can’t be charged rapidly, and you have to top the electrolyte off of them once a month.

This particular battery’s propensity to overheat when charging and incapacity to withstand subfreezing conditions are further drawbacks.

#2. AGM Batteries

Lead-acid batteries with Absorbed Glass Mats (AGM) are sealed batteries.

Although they were first created in the 1970s, RV boondocking has just lately become considerably more popular.

These batteries are spill-proof because all of the liquid electrolyte—unlike a typical lead-acid battery—is absorbed into fiberglass matting.

Compared to gel or lead-acid batteries, this kind of battery can be charged significantly more quickly.

No gases are released during usage or charging since the cells are sealed.

They also claim a 95% charge efficiency and don’t need any maintenance.

These batteries have a low self-discharge ratio and are also resistant to cold.

This battery’s drawback is its susceptibility to overcharging.

Despite being more expensive than regular lead-acid batteries, these batteries are not nearly as expensive as gel batteries.

#3. Gel Battery

Viscous gel electrolyte, which is used to make these batteries, is often thought to be safer than lead acid.

Because the gel cells are completely sealed, the electrolyte in these batteries cannot leak readily, and they don’t emit any gases when in use or charging.

Additionally, this kind of battery needs minimal maintenance and has a strong tolerance for extreme temperatures.

Oversensitivity to charge and a lack of tolerance for quick charging are drawbacks of this kind of battery.

These batteries may also be rather expensive, and unlike many other battery types, they need a particular charging profile.

#4. Lithium-Ion Battery

Lithium ions flow between the cathode and anode in this form of battery, which are often based on some sort of lithium salt solution that isn’t water-based.

Since they are stable, secure, and long-lasting, lithium ion phosphate batteries are the most often used kind of lithium ion battery for RV boondocking.

Rapid energy density and very high charging speeds are two benefits of this battery type.

Additionally, they are maintenance-free and do not have battery memory.

This kind of battery is extremely light and small, loses very little charge at low temperatures, and can be kept with a low charge without suffering any harm.

The primary drawback of lithium-ion batteries is their high initial cost compared to the other battery types.

However, if you spread out that expense across their whole lives, the picture changes.

Additionally, these batteries cannot be charged at low temperatures and need sophisticated battery management systems to be used properly.


A battery’s capacity is expressed in amp-hours (Ah) over a certain time frame.

A battery’s amp-hour measurement tells you how much power it can produce for an hour.

Most batteries undergo a 20-hour test with 5-amp loads.

However, the amount of time the battery is depleted for testing is indicated by the manufacturer’s time frame.

You must take into account the energy requirements of all of your equipment and appliances when calculating the demands of your RV.

Calculate the battery capacity you require for your RV’s boondocking needs by adding up all of the appliances and/or tools you like using concurrently and at certain times.

Increasing your capacity requirements after adding up your appliances’ energy requirements is always a smart idea.

You now have a bit more space to maneuver.

It’s great if your electronics and appliances use just 50 to 60 percent of the overall capacity of your RV battery.

By doing this, you may avoid deep discharges, which can reduce the lifespan of your battery.

Cranking Amps

This measurement illustrates how much power the battery must provide in order to start the motor of your RV.

Most manufacturers test the battery’s performance for 30 seconds with a load of 1.2 volts on each cell to determine the cranking amps.

If the battery you choose will also be used to start your RV’s motor, this measurement is crucial.

However, it is not a big issue if the battery will just be used to power the equipment and appliances in your RV.

Cold cranking amps and normal cranking amps are the two readings that the majority of batteries will show.

Regular cranking amps measure the amount of current supplied between 0 and 32 degrees Fahrenheit, whereas cold cranking amps measure the amount of current supplied at 0 degrees.

A measurement of hot cranking amps, which represents the amount of current delivered at 80 degrees Fahrenheit, is also available for certain batteries, although it is uncommon.

Discharge Depth and Cycle Counts

The depth of discharge of an RV battery indicates how completely the battery has been used up.

A battery that is completely charged, for instance, has 0% depth of discharge.

On the other hand, a battery that has completely lost all of its charge is said to be 100% discharged.

As an RV boondocker, it’s crucial to regulate the depth of discharge.

A battery’s lifetime will be reduced the more it is depleted before being recharged.

A battery’s lifetime discharge/recharge cycle capacity is also decreased as a result of this.

As a consequence, the number of cycles a battery has at a certain depth of drain will be specified by battery makers.

If you want your battery to survive as long as you expect when you purchase it, you need be cautious not to go above the advised depth of drain.


Even the best RV battery for boondocking won’t operate consistently across the board.

Although this is an inconvenient aspect of RV boondocking, you shouldn’t let it stop you.

It is now even more crucial that you take into account the ideal temperature working range of each battery before making a purchase.

It’s also a good idea to seek for a battery that can operate in humid environments and won’t completely fail when its remaining capacity approaches 50%.


Rough terrain is often included with RV boondocking as you look for the ideal, off-the-beaten-path campsite.

As a result, the battery in your RV has to be built to endure movement, shaking, and vibration.

Find a spill-proof battery so that you are ready for the rough, slick, or other difficult road conditions you may experience when boondocking.

To increase the battery’s overall longevity, ensure sure the housing is made of high-quality materials.

Which Battery is Best for Boondockers?

Your preferred style of boondocking will determine the ideal RV battery for you.

Let’s look at just a few more factors, even if the aforementioned factors should have given you a few excellent suggestions to help you limit down your battery options.

Full-Time Boondockers

The battery requirements of a full-time RV boondocker will vary from those of a casual, recreational boondocker.

You’ll need a battery that can work with solar panels while also giving your RV plenty of power on days when the sun doesn’t come out if you want to boondock full-time.

Since you’ll be using a lot of batteries, lithium-ion batteries are often the best option for reliable, long-lasting performance.

Part-time Boondockers

Even if you just boondock sometimes, you’ll still need a battery that can keep you going for many weeks at a time.

A lithium-ion battery could be a little excessive and out of your price range in this situation.

Your electric demands should be met by a deep cycle, lead-acid, or AGM battery for a few weeks at a time.

Just be cautious not to overdrain the battery and keep it in good condition.

Infrequent Boondockers

If you just boondock sometimes, you probably only require electricity for two or three days at a period.

A high-end lithium-ion battery will thus be unnecessary unless you have the funds to install one and don’t care about the cost.

A typical lead-acid battery will have enough charge capacity for a few days off the grid for the majority of occasional boondockers.

Tips for Buying Batteries

Before choosing an RV battery, always take your power consumption demands into account.

Consider the kind of appliances you have and how many of them you will use at any one moment.

If your arsenal is little, go with a 6V battery that is portable.

A 12V battery would be preferable for people who want a little bit more power.

To recharge your battery when it runs out of juice, you must purchase the proper battery charger.

Each brand and model is compatible with a certain kind of charger, so check what you’ll need before you purchase.

If you want a good journey and enough energy to keep you and your family comfortable, choose the correct battery type is crucial.

Although lithium batteries might be more costly, they are often significantly lighter and more portable.

While deep cycle RV batteries provide consistent power over a long length of time, they are often bigger and trickier to attach.

To determine how much charge is still in your battery and when it may be time to use your charger, you can always buy a battery monitor.

When your battery is running low on power, you run the danger of doing long-term damage to it.

Make careful to charge your battery whenever you get a chance while traveling.

Famous RV Battery Brands

Like the first three of our selections above, there are a lot of great solutions available from manufacturers that are a little less well-known but yet provide reliable performance.

That being said, looking at highly rated best sellers from reputable manufacturers is a smart place to go when you’re looking for the best RV battery for boondocking and don’t want to spend too much time investigating.

A benefit of purchasing from them is that there will be more evaluations to draw from when making your choice, which is crucial when it comes to batteries for lengthy boondocking excursions.

AGM batteries and lithium-ion batteries are capable of lasting longer.

The lifespan of lead-acid batteries is less than that of other, more costly batteries.

Many lithium batteries come with up to 10-year warranties.

Can A Regular Car Battery Be Used In An RV?

A conventional automobile battery may be used in an RV, although it is not advised.

They are manufactured differently and won’t endure for very long.

Deep cycle batteries are not used in automobiles.

They are designed for brief, high-amp use.

They are utilized to start your automobile for this reason.

Deep-cycle batteries are necessary for RVs.

When you use these batteries to run your lights and other essential trailer appliances, they are designed to be depleted more thoroughly and to progressively distribute amps over time.

Why Should I Use A Battery Of What Size In My Travel Trailer?

There isn’t a certain size that every camper van or travel trailer has to have.

If you have the room, we advise having around 200Ah in total.

On the other hand, this may change depending on how often you will use shore power or boondock.

You may need a battery with a minimum capacity of 400Ah if you want to live off the grid.

How much battery you consume will significantly affect whether you have a big or small RV.

If you start off with one or two batteries and you run out of power, and your battery compartment has room for more batteries, you should add one or two more.

Things To Take Into Account When Choosing The Best RV Battery

When searching for batteries for your camper van, motorhome, or RV, there are a few crucial factors to take into account.

The following would be the most crucial factors to think about:

  • What Is The Size Of Your Battery Compartment?
  • Will you routinely boondock or will you be linked to shore power? You will need extra batteries if you do more boondocking.
  • What kind of budget do you have for batteries? Batteries made of lithium may be pricey.
  • How much upkeep are you prepared to do on your batteries and how long do you want them to last?
  • Do you intend to make use of solar panels? Your ability to remain off the grid and store more energy from solar power increases with the number of batteries you have.

How To Care For The Best Camper Battery?

The biggest problem with lead-acid battery care is allowing batteries drop too low and having them stay at a low charge for too long.

Different batteries need various forms of maintenance.

Sulfation happens if a battery is allowed to drop below 40% and continues to do so.

On your battery plates, crystals start to form at this point.

Your battery will eventually die before it should because of this.

You must monitor your water level while utilizing a flooded lead-acid battery.

You must add water if your reservoir is low.

Your battery’s water evaporates as a result of frequent charging and draining.

Your battery will continue to operate normally if you add distilled water.

In order to avoid overfilling, add water after the battery has completely charged.

The battery may overflow when charging if water is added before it is completely charged.

Best Way To Maintain The Charge Your Rv Battery

You can maintain the charge in your batteries in a few different ways.

The best course of action is to make sure they are unplugged from all power sources.

Power is required for your RV’s clock and carbon monoxide detectors.

Your battery will become low from them.

Although many RVs include power disconnect switches, it’s possible that not all power sources are entirely disconnected.

Verify that the battery is not being drawn upon for power.

If you can, attach a battery tender after disconnecting your battery.

These little chargers maintain your battery’s charge gradually.

Over time, all batteries will eventually lose their charge.

To prevent sulfation, a battery tender will keep the battery charged.

Avoid Making Them Too Hot Or Cool

A battery must be maintained by attempting to stay away from extremes.

Batteries may be harmed by being exposed to extreme temperatures.

A battery may get substantially hotter when used often at high power.

Dust Off Your Best RV Battery

Periodic battery cleaning is an essential component of maintenance.

A battery cannot be charged correctly and cannot provide the necessary power if the terminals are dirty.

Clean battery connections reduce the likelihood of a depleted battery, which increases the risk of sulfation.

This will reduce the battery’s lifespan.

How Do I Charge RV Batteries?

A converter is often fitted in RVs.

When hooked into shore power, a converter is needed to charge your batteries.

One tool we use to keep our batteries charged is a converter.

You should check into purchasing a converter or making sure your converter is in working order if you do not already have one or are unclear whether you do.

Your camper’s lights do not operate on shore power.

Your bigger 110V appliances are powered by it.

Your deep cycle batteries are charged by the shore power via a converter, keeping your lights and other 12V power supply outlets operational.

How Can I Identify A Faulty RV Battery?

Simple output might help you identify when your batteries are beginning to degrade.

When your RV’s power is reduced, tasks that the batteries previously handled without difficulty – like utilizing the electric jack to raise and lower the camper—may become more difficult.

For My RV, What Sort Of Battery Do I Need?

Many RV owners choose between a 6V and 12V battery depending on their power requirements.

The 6V battery choice seems to be preferable since, if you need more power, you can always combine them to create a 12V power supply.

How Do I Install A Battery For An RV?

The battery type and manufacturer have a significant impact on how easily your RV battery may be installed.

While some batteries need simple maintenance, some require more involved care.

Never install your RV without first turning off all electricity to prevent damage and injury, and don’t be ashamed to hire an expert.

Conclusion: Best RV Battery

Depending on the circumstances, a different RV battery or batteries may be the best option.

Your LifePO4 cells will be the best camping battery, but they are quite pricey.

The conventional lead-acid, flooded batteries will do the job for the least amount of money, but they will need more upkeep and last less time.

Compared to standard, less expensive lead-acid batteries, sealed batteries need less maintenance and perform better.

No matter what choice you choose, don’t ignore upkeep.

Over time, it will enable you to save money.

The batteries are important and should be handled similarly, keep your battery compartment clean and organized just as you would keep your kitchen clean and organized with key items.
