best lithium battery for caravan

What type of battery is best for a caravan? Today, we review the Best Lithium Battery For Caravan and the best 200ah lithium battery. Lithium batteries pack more energy into smaller package. Let’s go on to our lithium deep cycle battery reviews. You need a lot more Amp hours in an AGM battery to get the same amount of Amp hours in a Lithium battery:

100Ah Lithium = 160Ah AGM
125Ah Lithium = 200Ah AGM
200Ah Lithium = 360Ah AGM

Bottom line? While you pay more for a lithium battery, you get more bang for buck with efficiency. They have higher performance, better longevity and require almost no maintenance.

You’ll typically find lithium batteries in your phone and laptop. They are also predominantly used in hybrid and electric cars. My father owns a Nissan Leaf and the performance of the battery pack is really impressive. In terms of leisure batteries for caravan and motorhomes, Lithium batteries also know as LiFePO4 and have some significant benefits. Compared to lead-acid technology Lithium can provide roughly double the energy density for half the weight!

Lithium batteries will also last much longer than lead-acid, up to potentially ten times longer. They also cope much better with frequent discharges to around 80% of their capacity. As you will have noted above, lead-acid batteries can be permanently damaged going below 50% of their capacity. However, if a Lithium battery is fully discharged it can cause damage. That’s why Lithium batteries have electronic controllers to stop full discharges.

Lithium leisure batteries have a much higher energy density and lower weight, however currently they are significantly more expensive: Image – Amazon

The only real downside to Lithium leisure batteries is their current cost. You will have to spend significantly more than you would for even the best lead-acid batteries. However, as electric cars start to become more common expect that price to drop significantly and for Lithium leisure batteries to become the default for caravans and motorhomes.

  • + High energy density with low weight
  • + Copes well with frequent and deep discharges
  • – Currently significantly more expensive

Used 12V Lithium Batteries

So as you can see from the information above, 12V lithium batteries have some significant benefits when it comes to their use as a leisure battery. The biggest downside is their cost. However, I recently became aware of Valance 12V lithium batteries.

Used 12V Valence Lithium Battery
Valence produces 12V lithium batteries which are used for commercial applications, therefore they are high specification batteries: Image – Valence

You will find Valance lithium batteries used in commercial EV vehicles and various other commercial applications. In the commercial sector, they typically replace these batteries every couple of years. However, these batteries are reported by some people to still have 90%+ of their capacity remaining!

Now, the ‘secret’ appears to be out about these used 12V leisure batteries and demand is currently outstripping supply. However, it’s expected many more of these used 12V lithium batteries are going to be available in the coming years.

Caravan Battery Review: AGM vs Lithium

AGM or lithium? If you’re buying a caravan battery, this is one of the first decisions you need to make.

Back when the only choice was lead acid AGM batteries, the answer was simple. AGM batteries provided everything you could want in a deep cycle and starter battery.

Then along came lithium and everything changed. Lithium batteries promise higher efficiency, better life cycles and lightweight package – just for a much higher price.

So, which one do you choose for your caravan? Best Caravan Battery?

Take a look at our AGM vs Lithium Caravan Battery Review:


One of the biggest benefits of AGM batteries is they are cheap. Why? It simply comes down to the fact that they are the cheapest to produce.

The $1300-3000 price-tag of lithium batteries is the main thing stopping people from buying them. But this price is dropping every day, making them a more attractive option for mobile power. Especially when you realise what you get for your money.

Pro tip: buying a lithium battery in a bundle will save you money and provide you with everything you need for your setup!

Lithium vs AGM Capacities:

Lithium batteries pack more energy into smaller package. You need a lot more Amp hours in an AGM battery to get the same amount of Amp hours in a Lithium battery:

100Ah Lithium = 160Ah AGM
125Ah Lithium = 200Ah AGM
200Ah Lithium = 360Ah AGM

Bottom line? While you pay more for a lithium battery, you get more bang for buck with efficiency. They have higher performance, better longevity and require almost no maintenance.

Depth of Discharge:

A battery’s depth of discharge (DoD) is the percentage of the battery that has been discharged relative to its overall capacity.

  • 100ah of lithium will give you 80Ah
  • 100 ah of AGM will give you 50Ah

Therefore, in the battle of AGM vs Lithium, you’re looking at 50% vs 80%. This means AGM’s are best suited to caravans that are used every few months, not all the time.

Life Cycle:

Lithium batteries win the life cycle battle. A lithium battery will give you almost double the life cycle of an AGM. This simply means you’ll need to replace an AGM battery sooner than a lithium battery. That upfront cost isn’t looking so bad now, right?

Size and Weight:

When it comes to the weight and size, lithium batteries win hands down. Lithium batteries are a more compact, lightweight option compared to AGM lead batteries. The clue is in the name: AGM lead acid batteries contain more lead, making them much heavier.

So, you can save on size and weight in your RV. How much exactly? Lithium batteries can save up to 70% of the weight and volume of traditional lead batteries of similar capacity.

This is where AGM takes the win. AGM offers some hybrid batteries which can be used for cranking and deep cycle. However, you can’t use lithium as a cranking battery. Will My Camping Battery Run?

Our Verdict: AGM vs Lithium

If you’re on a budget, need cranking or only want to a run a 4×4 fridge, AGM is the battery for you. Keep it simple and cheap.

But if you’re hitting the road for a long trip and want to run high current appliances and gadgets, lithium batteries offer heaps more advantages in weight, size and efficiency.

Lithium requires less maintenance and lasts a lot longer. True, you pay more upfront, but you’ll get almost double the life cycle of an AGM. Who can argue with that?

Where to Buy Cheap Batteries

When it comes to getting the best price on batteries, there are a few rules to follow. For example, price comparing, waiting for deals, and buying off-brand are three great ways to save. Using these methods, you can find great prices on batteries at Walmart, Sam’s Club, Amazon, Costco and Best Buy.

“My one rule is that no one should ever buy a brand-name battery,” says money expert Clark Howard. “Almost all of the off-brands or store-brands are made by one of the majors.” 

Knowing that the quality would be the same or similar, I researched prices for some of the most popular and most affordable off-brand and store-brand batteries.

Below, you’ll find detailed information on where to find the best prices, and ultimately, where to make your final purchase. 

Where to Find the Best Deals on Batteries

Over the past four years, our team at has been looking for the best deals available online. In that time, we’ve seen more than 30 great deals on batteries. In the chart below, you’ll see that many of those deals came from Amazon, Best Buy, Meh, The Home Depot and Walmart.

Battery Deals Posted by Since 2016 from Amazon, Best Buy, Meh, Lowe's The Home Depot and more.

As you can see, we’ve posted most of our deals on batteries from Amazon. The best deal we’ve seen on AmazonBasics AA batteries was a 100-count pack for $14. That’s only 14 cents per battery!

We’ve also posted several deals on batteries from Best Buy. In the past, Deals of the Day have included 48-packs of AA and AAA Insignia batteries for as low as $6. If you can catch this deal, you’ll be paying just 13 cents per battery. That’s the lowest price we’ve seen!Advertisement

Daily deal sites like Meh also offer great deals on batteries, but in my experience, they sell out fast. We’ve seen some great deals on bulk batteries from these sites in the past including 192-count packs for $30 at Meh. At 16 cents per battery, you’re still getting a great deal.

In the past, The Home Depot has matched Best Buy’s all-time-low pricing with a deal on a 60-pack of its store-brand HDX AA batteries for $8. Meanwhile, Walmart has been a close runner-up with past deals on 50-count packs of discount batteries for $6.97. That means you’d be paying only 14 cents per battery.

The Top 5 Best Places to Buy Cheap Batteries

While finding a great deal on batteries is one of the best ways to get the lowest price per battery, you may not be able to wait for the sale. If you’re looking for the lowest daily prices on batteries, check out Walmart, Sam’s Club, Amazon, Costco and Best Buy. 

I visited each retailer’s website to find the best available deal on AA and AAA batteries at the time of this writing. I’ve provided details about each store later in this article, but just below you’ll see the per-battery cost of each deal: 

Sam’s Club$0.31$0.29
Best Buy$0.42$0.42

Sam’s Club, Amazon, Costco and Best Buy offer competitive prices on store-brand batteries while Walmart offers great deals on generic brands. As a comparison, I found CVS-brand AA batteries for 69 cents each and AAA batteries for 78 cents each. At the same store, name-brand Duracell batteries ranged from $1.35 to $1.90 each!

“If you buy batteries at a drugstore, convenience store, supermarket or anything like that, what you’re paying per battery is mind-blowing,” says Clark. “So, it’s not just that you buy the store brand, it’s where you buy also that really matters.” 

For the best overall prices, consider shopping at one of these top five places to buy cheap batteries:

1. Walmart

ACDelco AAA batteries at Walmart

While Walmart doesn’t offer private-label batteries, you can still find some of the best prices on off-brand batteries at At the time of this writing, I found a 60-count pack of AA Rayovac batteries for $17.97 and a 100-count pack of AAA ACDelco batteries for $24.99. These were the best deals I found on AA and AAA batteries during my research.

Note that while you may find low prices online at Walmart, you can expect additional shipping fees if in-store pickup isn’t available

While Walmart’s prices are great on off-brand batteries, name brands come with a bigger price tag. For example, a 36-pack of Duracell AA batteries was available for $30.05 at the time of writing, which means they cost 83 cents each.Advertisement

2. Sam’s Club

Member's Mark AA batteries from Sam's Club

If you’re a Sam’s Club member, this is a great place to shop for cheap batteries. 

When I compared prices, I found Member’s Mark 48-count packs of batteries for $14.98 and AAA batteries for $13.98. At the time, there was a $2-off Instant Savings discount on the batteries. That made these two available deals the second-best I’d seen.

“Sam’s Club’s a great option,” Clark says on shopping for cheap batteries. “It has all five major batteries in the company’s private label, and you just save money!” 

Sam’s Club’s store brand, Member’s Mark, is available in AA, AAA, C, D and 9-volt sizes.

3. Amazon

AmazonBasics AA batteries from Amazon

For Amazon Prime members, AmazonBasics batteries are going to be hard to beat. 

“I’m a big fan of AmazonBasics,” says Clark. “They’re not as cheap in the AA and AAA batteries, but the AmazonBasics 9-Volt, the Cs and the Ds are a real deal.

While the AmazonBasics didn’t have the lowest prices I saw, they were still very competitive at only one or two cents more per battery than Sam’s Club. In the past, our team at ClarkDeals has found AmazonBasics AA batteries even cheaper at $14 for 100. That drops the normal 31 cents per battery price to only 14 cents!

Of course, Prime members are eligible for free two-day shipping for even more savings.Advertisement

4. Costco

Kirkland Signature AA batteries available at Costco

In the past, Costco’s Kirkland Signature batteries have been the best available deal. While you can now find other off-brand batteries cheaper elsewhere, Kirkland Signature is still a great choice. In fact, Consumer Reports included the Kirkland brand in its “Top 5” recommended batteries roundup. These batteries are also the only brand considered a “Best Buy” on the same list.

Even though Kirkland Signature no longer has the lowest per-battery cost, you can rest assured that you’re getting quality batteries for under half the price.

“At Costco, it’s Duracell that makes Kirkland Signatures,” says Clark. “They’re not similar batteries; they’re identical.”

CVS offers Duracell batteries at $1.35 to $1.90 each. With Kirkland Signature, you’re getting the exact same thing for only 35 cents: That’s $1 less per battery!

5. Best Buy

AA Insignia batteries available from Best Buy

As you can see above, Best Buy’s Insignia batteries aren’t going to have the lowest daily price you can find. However, if you can grab Insignia batteries on a day they’re on sale, the price will be impossible to beat.

In the past, ClarkDeals has seen daily deals including 48-count packs of AA and AAA batteries for as low as $6. That’s only 13 cents per battery! Again, that’s the lowest price we’ve seen. I always try to grab this deal when it comes up, and the batteries last a long time.

Bookmark this page to keep up with the best daily deals at Best Buy, and when you see the batteries on sale, be sure to get them! Choose free in-store pickup nearby to avoid any additional shipping costs. In my experience, they’re typically ready for pick up in less than an hour.

Final Thoughts

Overall, you’ll likely find low prices on store-brand and off-brand batteries at Walmart, Sam’s Club, Amazon, Costco and Best Buy. Advertisement

If you see a good price on a battery brand that you’re not familiar with, especially at a store like Walmart, be sure to read customer reviews and check out Consumer Reports’ battery reviews to learn more about the brand’s performance.

“There are some sellers who sell these batteries that aren’t very good,” cautions Clark. “So if you buy completely off-brand batteries, you could end up with one that’s very unreliable and doesn’t have a long life.”

Sam’s Club members, Amazon Prime members and Costco members all have access to great prices on quality store-brand batteries like Member’s Mark, AmazonBasics and Kirkland Signature batteries respectively. Free shipping with these options also leads to additional savings. 

Finally, hold out for the sale on Insignia batteries at Best Buy if possible. With this deal, you have the chance to get the lowest per-battery price that our team has seen in the past!

No matter where you decide to shop, be sure to use a tool like Google Shopping to make sure you’re getting the best available deal before purchasing.
