The Best Leisure Battery For Campervans & Motorhomes In 2026

Last Updated on 10/09/2026 by Louise

Campervan batteries are an essential part of your van setup whether you plan to use electric hook-ups for your campsite holidays, park up in fields for weekend-long festivals or live off grid with a solar kit set up.

However you plan to harness energy for your appliances, it’ll need to be stored somewhere and that place is your campervan battery.

Delving into campervan electrics can expose you to a whole new world of confusing technical terms. Phrases like deep cycle, amp-hours, series, and parallel can easily cause your eyes to glaze over.

As an engineer, I want to simplify the science. This guide breaks down the technical details and highlights the best campervan leisure battery options in 2026.

The Science Behind Batteries!

Starter battery vs leisure battery

Batteries designed to start your vehicle (crank or starter batteries) work differently than batteries intended to run living appliances (leisure or deep-cycle batteries).

• Starter batteries: Deliver a massive, quick surge of power to get the engine running.
• Leisure batteries: Release energy slowly and steadily over a long period.

There are also dual-purpose batteries that can handle both jobs. They offer enough surge power to start a vehicle while managing light appliance usage. Because most van appliances run on direct current, all options reviewed in this guide are 12V batteries.

What is Depth of Discharge and Battery Cycle?

Leisure batteries are known as deep-cycle batteries. They are engineered to discharge down to a specific level and recharge hundreds of times over their lifespan.

• One Cycle: Consists of one discharge and one subsequent full recharge.
• Depth of Discharge (DoD): The percentage of the battery capacity that can be safely used.
• Safe Limits: Lead-acid batteries should generally only be discharged to 50%, while lithium batteries can safely handle up to 80%–90% DoD.

Note: You should never completely drain a leisure battery, as this permanently damages its capacity.

Leisure batteries can be charged by an alternator (via your engine whilst driving), solar power or from an electric hookup.

Types Of campervan Leisure Batteries Compared

There are two broad categories of lead-acid options: open (vented) and valve-regulated (sealed).

Open lead-acid batteries emit hydrogen and oxygen gases. They require external ventilation, regular deionised water top-ups, and must stay strictly upright to prevent dangerous leaks. Because of this, open lead-acid batteries are not recommended for campervans

Valve-regulated lead acid batteries are sealed so do not require ventilation or the need to be mounted upright and do not need topping up with deionised water. For these reasons they are well suited for camper van life.

There are two types of valve regulated lead acid batteries: Absorbent glass mat (AGM) and Gel.

Finally, there are lithium batteries, which are common types of batteries that are found in many modern days gadgets from phones to electric bikes.

Battery Type	Safe Depth of Discharge (DoD)	Average Lifespan	Pros	Cons
AGM (Absorbent Glass Mat)	~50%	3–5 Years	Affordable, spill-proof, handles solar charging efficiently.	Heavy, performance drops in extreme cold.
Gel	~50%	5–7 Years	Highly shock-resistant, slightly longer life than AGM.	Heavy, slower charging speeds.
Lithium (LiFePO4)	80% – 90%	10+ Years	Ultra-lightweight, rapid charging, massive lifespan.	Expensive upfront investment.

1. AGM

AGM batteries are the cheapest type of valve regulated lead acid battery. They are completely sealed which means that no nasty acid can spill out and no harmful gases are released. They can be mounted in various position (except upside down!) and require very little maintenance.

They are also resilient to vibrations, charge well off solar power and have a fast charge speed. For these reasons AGM batteries are popular in the camper van and motorhome world. Their biggest downside is that they are heavy and they don’t function as well in very cold climates.

2. Gel

Gel batteries have all the benefits of an AGM battery and typically have a longer lifespan if they are adequately cared for. Their biggest downside is their weight.

3. Lithium

Lithium batteries are found in almost everything these days. There are different types of lithium batteries but the most commonly used type is LiFeP04. Lithium batteries can provide as much energy as a lead acid battery for half the size and weight. These are two huge bonus points when it come to van life.

The life span of a lithium battery is 10 times that of a traditional lead acid battery and has a DOD of upto 90%. Since there is no liquid in a lithium battery they can be mounted in anyway (including upside-down!) and again require little maintenance. They also charge much faster than lead acid batteries.

Their biggest downside is the hefty price tag attached. However, since lithium batteries have a much longer life span, in the long run (by this I mean 10 years or more) the price difference will even itself out.

Things to Consider When Choosing Your Camper Van Leisure Batteries

1. Upfront Cost vs. Long-Term Value

When it comes to power storage, spending more money usually secures a vastly superior product. If budget is no object, lithium is the clear winner.

• Choose Lithium if: You plan to live in your van full-time or travel off-grid frequently for years.
• Choose AGM/Gel if: You only use your van occasionally, have strict budget limits, or plan to sell the vehicle soon.

2. Battery capacity (Ah)

Battery capacity is measured in ampere-hours (Ah). This represents how much current a battery can supply over time (e.g., a 100Ah battery can theoretically provide 1 amp for 100 hours, or 10 amps for 10 hours).

Physical size scales up with capacity. If you need extensive power storage but have tight layout restrictions, you can connect two identical smaller batteries in parallel (wiring two 100Ah batteries together to create a single 200Ah bank).

Your required capacity depends entirely on your travel style. If you are a weekend warrior who only needs to charge a phone and power a few LED lights at night, a 100Ah battery will be more than enough to meet your needs.

3. Lifespan

A battery will have reached the end of its life when it cannot hold more than 60/70% of its initial capacity. The lifespan may be stated on the battery in years or in cycles, which if you remember from above is the amount of times a battery is discharged. The battery won’t stop working completely after the stated amount of cycles, they just won’t perform as well.

Sealed lead acid batteries typically last anywhere from 4 – 8 years, whereas lithium batteries can last 10 – 20 years.

4. Temperature range required

If you’re planning on taking your van to extremely cold climates, firstly I hope you have a good heater (!) and secondly consider a lithium battery rather than a lead acid battery, since these perform better in cold temperatures. Consider investing in a lithium battery with built-in heaters which will protect the battery from cold charging.

5. Weight

All van lifers will examine the weight of a product before they consider adding it to their van. It’s just one of those funny facts of life as a campervan owner. Weight increases fuel consumption by your van so if this is a big priority for your van build or conversion, consider the much lighter lithium batteries instead of lead acid versions.

6. Size

If you’re replacing your current battery and it has a designated spot in your van, battery dimensions will be a hugely important factor. If you’re building a van from scratch, consider you power requirements and the battery space this will require before committing to buying a battery.

Leisure Battery For Campervans Review: The Top 3

Now we’ve gone through the science and terminology, hopefully you’ll be better equipped to understand my campervan and motorhome leisure battery reviews below.  

1. Platinum AGM 12V 100Ah – Overall Winner

For me this is the best battery for campervans and motorhomes because it has the best performance to cost ratio. It’s not the cheapest AGM battery available but as mentioned before, with batteries you tend to get what you pay for.

Platinum are a well established battery producer and this battery comes with a 3 year warranty. With this warranty you can feel confident to get at least 3 years usage from it.

This battery has been given the A class by the National Caravan Council which is the highest rating a battery can get. Boom! This basically means that this is a high capacity battery designed for users who plan to live off grid.

Since this is an AGM battery it will charge well off solar panels, will be resilient to vibrations and won’t require any ventilation or maintenance. 

This is the battery I use in my van which I lived in full-time, off-grid for two years. Prior to that I was only using the van part-time. I use this battery with a 175W solar panel and MPPT charge controller and it provides/stores enough energy to run a fridge, heater, lights and charge my laptop, phone and multiple other gadgets. 

The only time it came up short was during our winter trip to Georgia. Here the short winter days, coupled with lots of snow meant we struggled to produce and store enough energy for more than a day without driving. If you plan on living in your van through the winter, I’d opt for the lithium battery instead.

2. Renogy Smart Lithium LiFe PO4 100Ah – Best Lithium Battery

This lithium battery is half the weight of the Platinum AGM battery and with 5000 cycles at 80% DOD, it should easily last 10 years. It’s small, light, robust, can be mounted in any way and will work in sub-zero temperatures.

If you’re tight on space, want to keep your van weight down, want to travel to cold climates (like doing a ski season) or plan to live off-grid in your van for many years to come, then this would be the top leisure battery choice for your camper.

If none of those things apply to you, then save your money and get the AGM battery instead. Even if you’re a heavy electricity user, you can get two AGM batteries and still have plenty of money to buy beers to put in your deliciously cold fridge!

If money were no object I would get this lithium battery from Renogy or possibly even two (I said money was no object right!). This battery provides an 80% DOD and an AGM battery provides a 50% DOD, so I would get 30% more Ah from every cycle when compared to the Platinum AGM 100ah.

It basically means I’d never have to worry about energy storage for the rest of my campervan life! Prices are often cheaper with Renogy and Renogy do have large discounts during sale events such as Black Friday.

3. SuperBatt Dual Purpose 120Ah – Best Dual Purpose Battery

If you only plan to use your van occasionally and don’t need a dedicated leisure battery, then a dual purpose battery is what you need. This is a battery that will start your van engine but also run appliances.

The SuperBatt Heavy Duty battery is a maintenance free, lead acid battery with hybrid technology which makes it ideal for use as a starter battery and a leisure battery. It has a low self discharge rate which means it doesn’t loose power quickly and provides 120Ah which is more than enough to charge all of your appliances over the course of a weekend.

At just over £100 this is also a battery that won’t break the bank and comes with a 2 year warranty. Even better!

Leisure Battery for Campervans Summary

Along with solar panels, a charge controller and wiring, leisure batteries form a vital part of your campervan solar setup.

As with many things, when it comes to campervan batteries you definitely get what you pay for. However, factors such as budget, space and planned electricity usage will dictate which battery you should choose.

AGM leisure batteries offer the best performance to cost ratio and for this reason would be a smart choice for most van lifers. However, if you’re converting your own campervan which you know you’ll have for a good 10 years or plan to spend time visiting very cold climates, then splashing out on a more expensive lithium battery would be the way to go.
