Buyer’s Guide 

Not sure what to look for when searching for your new campervan battery? Have no fear; our handy buyer’s guide can help you there! Choosing a new battery can be a daunting task, but it doesn’t need to be by following our guide and looking at these factors! Let’s get into it!

Is It Compatible? 

Before we go any further, you will need to check if the battery will be compatible with a solar power system. If you don’t currently have one, then it’s one less thing for you to worry about currently!

However, we strongly urge you to install a solar power system in your campervan/RV. They are a fantastic way to access energy (and greener too). 

If you have a system, check that the battery you are looking at is compatible with the system you have in place. This information can usually be found in product descriptions, where a list of compatible sources should be given. If not, you might need to contact the manufacturer directly for more information. 

Battery Types – What Do They Do? 

There are a few different types of batteries on the market, and they all work slightly differently. If you are new to the world of campervan batteries, this can be confusing. But it doesn’t need to be! Below are the different battery types and their purposes to help you understand them better and select the best one for you! 

Starter Battery 

First up is the starter battery, which provides a jolt of power to get your engine’s motor started. Typically, 20% of their energy capacity is used to start your vehicle. It’s an important battery to run your camper, but not necessarily the type of battery you need for providing power to your lights, electronics, or other camping accessories. 

House Battery 

Next, we have the house battery, which is used to power your appliances and campervan accessories. Also known as leisure batteries, these are needed to operate your refrigerator, lighting system, electric toilet, and water pump. You can charge a house battery with an alternator, solar power, or shore power hookup.

In most cases, you will have both a house/leisure battery and a starter battery. It’s the most common configuration we see in campervans and motorhomes. 

Types Of Campervan Batteries 

There are a few different types of campervan batteries to choose from, so let’s look at those now with some handy pros and cons to help narrow your search. 

Flooded Lead-acid Battery 

Flooded lead-acid (FLA) batteries feature lead and liquid sulfuric acid, which creates a chemically charged current. They are a popular choice due to their affordable price and long lifespan. 

They are also the oldest battery technology, adding to their popularity, and are still a common option for campervan and RV owners. However, it’s not all rosy when it comes to these batteries. 

The battery stores liquid sulfuric acid, as we mentioned, and can be dangerous. If it leaks, the battery can cause corrosion or damage to your campervan! You must keep the battery in an upright position at all times to prevent this. 

You will also need to be mindful that it releases oxygen and hydrogen particles when charged. These fumes are toxic if inhaled, meaning you also need proper ventilation installed in your van to prevent any health scares or emergencies while using a flooded lead-acid battery.

And despite their low initial cost, they can be expensive batteries to run in the long term. They need to be topped off monthly, adding to their cost and becoming a drain on your time. You will need to care for these batteries correctly to prevent their battery life and efficiency from deteriorating.

It’s worth weighing up these factors before deciding if this is the right battery for you! 

Pros 

  • Affordable making them suitable for a range of budgets
  • Come in a range of sizes

Cons

  • Must be kept upright at all times
  • Not the most efficient in colder climates
  • Requires a lot of maintenance
  • Potentially hazardous materials that cause damage and pose a health risk 

Gel Batteries 

Next, we have gel cell batteries. They were introduced to the market as an easier option than an FLA battery. They feature the same technology, but the electrolytes are suspended in a gel rather than a liquid. 

Their main advantage is their increased safety compared to FLA batteries. No fumes can escape, so you don’t need to worry about toxic gasses circulating in your van. They are also sealed and contained in a protective case, so you don’t need to worry about your battery leaking if it tips over! 

Gel batteries are also far lower maintenance than FLA batteries, saving you time! They are the perfect choice for those who don’t use their RV or campervan often or don’t have a great deal of time to spend maintaining them. 

There is a downside to these batteries, though. Gel batteries tend to have a lower output compared to FLA batteries. You might find this an issue if you have a lot of appliances to run. They are also more expensive to purchase, so be sure to consider your budget before deciding. 

Gel batteries also don’t have the long lifespan that other campervan batteries do. You can extend the life of your gel battery, though, so it’s not the end of the world! You will want to recharge it properly to extend its battery life.

Be careful to use the specific charger for your battery, though! Using one that isn’t designed for your battery can cause it to burn out quickly! 

Pros 

  • Little maintenance required 
  • Safer than lead-acid batteries 
  • Can sit for extended periods without use 
  • It doesn’t need a flat surface or to be kept upright.

Con

  • Expensive 
  • Less efficient than flooded lead-acid batteries 

AGM Battery 

AGM deep cycle batteries, or Absorbent Glass Mat batteries, are among the most popular batteries on the market! From RVs and boats to auto manufacturers, these batteries have become a go-to option!

The sealed lead-acid battery works similarly to gel batteries but with the electrolytes suspended in soaked glass fibers. 

This setup ensures that the AGM battery does not leak or spill any hazardous materials if it is knocked over. It also does not need regular maintenance as FLA batteries do. It’s these reasons that make it a popular choice for many campers! 

However, these batteries do have some drawbacks we need to mention. Like the gel batteries we looked at earlier, AGM batteries have a low energy output, making them less efficient over time. They also don’t perform as well in colder climates, which can be a problem if you use your campervan throughout the winter months. 

It’s worth considering all of these factors before deciding if this is the right battery for you or not! 

Pros

  • Less maintenance required than other batteries 
  • Small and compact size 
  • Can sit for extended periods without use
  • You don’t need a flat surface to install it 

Cons

  • Not efficient in colder climates
  • Produces less energy than FLA batteries 
  • Expensive 

Lithium Battery 

Finally, we have lithium batteries, which are considered the most robust form of campervan battery technology on the market! Lithium batteries tend to last longer, have faster charge times, and require the least amount of maintenance!

It’s these factors that make the battery a popular choice for campervan and RV owners! 

However, these are some of the most expensive batteries on the market. Their higher price point can put many people off buying them, but if you have the budget, lithium batteries are an option we would certainly consider. 

They do require some maintenance but compared to FLA batteries, it’s very minimal! Lithium batteries must always be charged above 20%, meaning you will need to monitor them throughout the year, even when you aren’t using them.

It can be frustrating if you don’t use your campervan regularly, but for those always on the go, keeping an eye on your battery shouldn’t be too much of a task! 

Although some maintenance is required, we think it’s worth it. If you can afford the higher price point, a lithium battery is the best one you can buy in terms of efficiency and performance. 

Pros 

  • It can be run to empty before needing to recharge 
  • Charges quickly
  • Long life-span 
  • You don’t need a flat surface to install it 

Cons 

  • Expensive 

Battery Capacity – How Much Do You Need?

Now that we’ve looked at the types of batteries and helped narrow down your choice let’s look at some other factors you need to be aware of! The first is the battery capacity.

To work this out, you will need the size of the battery, which is usually stated in the product description. 

The battery size is measured in amp-hours (Ah) and will tell you the battery’s amount of power on a single charge. To determine if the battery capacity is enough 

for you, work out how many amp-hours you need to power the appliances in your RV. 

For example, one appliance that uses 1 amp of current for 1 hour will use one amp-hour. So to run the appliance for 24 hours, you would use 24 amp-hours of power.

If you have multiple appliances drawing from one battery, you will want a battery with a larger amp hour size to power all of your accessories with ease. 

Be mindful that these larger batteries often come with a heftier price tag. Consider your budget as well as the capacity you need when shopping for your new campervan battery. 

Flooded lead-acid batteries will last between four to eight years, with regular maintenance needed to keep it up to speed and functioning as it should!

AGM deep cycle batteries tend to last simultaneously but lose power capacity after roughly seven years of use.

It’s considered a mediocre lifespan, but remember, these batteries need less maintenance than a flooded lead-acid battery, making them a more favorable option for many campervan owners. 

Gel batteries have an even shorter lifespan, with an average of two to four years. Now that can seem short, but it’s worth noting that if you care for them properly and charge them with a gel-specific charger, not only can you prevent burnout, but you can see them last for 15 years!

If you are prepared to put the maintenance in, your battery will thank you!

For a durable battery though with a long lifespan, opt for a lithium battery. They have an impressive lifespan of between seven years and twenty years!

You will pay more for the battery, but you won’t need to worry about replacing it every few years. You could even save money in the long run, buying one battery in the same space others are buying 3! 

It’s worth noting that these lifespans are just averages. How you care for and maintain your battery will dictate how long it lasts and how well it functions during this time! 

Lifespan – How Long Will It Last?

When it comes to searching for your new campervan battery, you want one that will stand the test of time and wherever the road takes you, which means you need to consider its lifespan. Depending on the battery type, there will be different lifespans.

It’s important to check these and make sure you select the battery that best suits your needs to avoid forking out a new battery every few years. 

How Big And Heavy?

Another factor to consider is the size and weight of the battery. Generally, a 12 volt 100Ah battery will weigh roughly 44lbs (20kg).

In some cases, RV owners might want a double bank battery system, which adds twice as much weight to your van build. For those with big payloads, this might not seem like much of a worry to you. 

However, for those with smaller campervans, the battery can be one of your heavier items. Be sure to check the maximum weight your campervan can handle before purchasing a heavy battery that will be difficult to cart around. 

It’s also worth checking the space you have to ensure that you have enough room for the battery! Leisure batteries can be heavy, but they tend to be compact, especially compared to other appliances in your van.

Most campervan owners find it fairly easy to fit one or two batteries inside their camper, especially if they have lots of space! 

We recommend mounting your battery, too, even if it has a spill proof guarantee. Mounting your battery can free up some space and also means you can drive with peace of mind!

You won’t need to worry about your battery falling or getting knocked and dented while you drive. 

12 Volt vs. 6 Volt – Which Is Best?

A question that comes up time and time again when searching for your new RV battery is whether a six or 12-volt battery is the right choice.

Usually, RV and campervans will come with a 12-volt battery as default. These batteries tend to be cheaper and easier to find than 6V batteries. 

But that doesn’t mean we should rule out 6V batteries! These batteries have a larger amperage when connected in a series and can be recharged more frequently too! 6V batteries tend to last longer, too, due to their thicker plates and more space per cell.

They also feature a deeper discharge compared to the average 12V house battery you see in campervans. 

It’s worth looking for 6V batteries if you have the budget for one and want to benefit from these added features. If they are a little out of your budget, then stick with the standard 12V battery. 

Series Or Parallel – Which Connection Is Best?

You can combine RV batteries to create a larger power source by joining them in a series or parallel connection. But which one is the right choice to make? Well, it depends on what you want from the connection!

If you want to keep the same amperage but add extra voltage to your battery bank, connect your batteries in a series.

If you have two 6V batteries with 10-amp hours each, connect the negative terminals to positive terminals with jumper cables to create a battery bank with 12V of power and a ten amp-hour capacity. 

However, if you want to increase your current but keep the same voltage, you can use a parallel connection. This involves connecting the two positive terminals to the two negative terminals.

If you did this with two 6V batteries with ten amp-hour, you would boost the amperage to 20 amp-hours. However, you will still only have the same power storage of 6V. 

Consider what connection would be best for your setup if you want multiple batteries and use the one that will benefit your campervan the most!
