The best caravan leisure battery will provide 12-volt power for your tourer, enabling, low voltage devices and appliances to be used when you don’t have 240-volt hook-up power. Typically this will include your lighting, 12V television and water pumps, while appliances that require more current, such as heating and hot water boilers will flatten a leisure battery in a relatively short time.

Certain devices are available in 12V formats for caravanning, such as the best caravan kettles and the best caravan toasters, though they aren’t as powerful as their domestic equivalents. A leisure battery charges when your caravan is being towed, and when it’s plugged into a hook-up post. You can also charge it with a trickle charger (see C-Tek) when it’s on your drive or in storage.

These products come in various guises, so to help you find the best caravan leisure battery for your needs, we’re sharing our favourite picks, including lead-acid batteries (which also come in various styles), and lithium options. Most people use lead-acid leisure batteries, but those who require more power for longer – like off-gridders – may opt for the extra potency of a lithium battery. However, it’s worth noting that lithium batteries cost considerably more than standard ones.

In this guide, you’ll find our top picks, featuring brands such as Yuasa, Renogy and Halfords, so you can buy a good leisure battery with confidence.

The best caravan leisure battery:

Yuasa L36 AGM

Yuasa L36 AGM

  • Output: 95Ah
  • Size (LxWxH): 335 x 175 x 190mm
  • NCC rating A

Reason to buy:

  • Portable, spill-proof design, easy to fit in standard battery lockers

Reason to avoid:

  • Lowest output of all the options in our guide

This premium battery is an AGM (absorbed glass mat) design, in which the acid doesn’t float around freely, but is absorbed into fibreglass mats. We like how this improves performance and creates a spill-proof design that offers extra protection against severe bumps and knocks.

As a deep-cycle unit, that provides up to 1140 Watt/hours, we think the L36 will be ideal for high-consumption devices like the best caravan movers and auto levelling, and will deliver optimal output when repeatedly discharged and recharged (up to 400 charging cycles).

The L36 is maintenance-free and has carry handles, making it more portable. It comes with a two-year warranty and is sized to fit easily in all standard battery lockers.

Halfords Leisure Battery HLB700

Halfords HLB700

  • Output: 100Ah
  • Size (LxWxH): 353 x 175 x 190mm
  • NCC rating: B

Reason to buy:

  • Good safety features, comes ready to fit

Reason to avoid:

  • May not fit smaller or older caravans, eats into payload

Capable of 200 charging cycles, this battery pumps out 100Ah and up to 1200 Watt/hours, making it a decent choice for those with larger power requirements. However, we should point out it isn’t NCC A-rated like the Yuasa battery above, so motor mover users might want to check its compatibility with their mover manufacturer.

Safety-wise it features an integrated flame arrestor, and each battery comes fully-charged from the store, ready to fit, something that we think is a useful feature. It’s also a sealed and maintenance-free design.

Be aware that the elongated design of this battery means it may not fit into all caravans, especially smaller and older ones. You’ll also have to allow 24kg of your payload to carry it. It comes with a two-year warranty.

Numax XV31MF

Numax XV31MF

  • Output: 105Ah
  • Size (LxWxH): 330 x 172 x 242mm
  • NCC rating: B

Reason to buy:

  • Ideal for caravanners who store their tourer over winter

Reason to avoid:

  • Not suitable for all motor movers

This wet/flooded, deep-cycle battery from top manufacturer, Numax, delivers 105Ah and is good for 500 recharge cycles. It features sealed-battery technology and has a handy, built-in state-of-charge indicator. The design offers low discharge rates when the battery’s not being used, making it a great choice for those who store their tourer over the winter.

Smaller in size than some high-output batteries, this Numax should slot easily into all caravan battery boxes. As some motor movers require a 110Ah output, we’d recommend checking before buying this battery.

Numax batteries come with a full three-year warranty, though 500 cycles should take even a prolific caravanner way beyond that.

Renology 12V Lithium Ion Phosphate Battery

Renogy 200Ah Lithium Leisure Battery

  • Output: 200Ah (expect up to 212Ah)
  • Size (LxWxH): 522 x 240 x 219mm
  • NCC rating: N/A

Reason to buy:

  • Offers good lifespan, great power output

Reason to avoid:

  • Quite weighty, relatively expensive

Here’s an oversized leisure battery that offers huge power output, but at a price. This Renogy LiFePO4 lithium cell, delivers +6% output (212Ah) according to the maker and will deliver optimum performance for 5000 deep charging cycles, which should easily exceed 10-years of constant use.

We think this would be a good leisure battery for hardcore off-gridders, who can link these batteries in series and parallel, or series-parallel, to offer huge power reserves.

This Renogy model is a ‘smart battery’ that self-regulates and includes low-temperature cut-off, so winter touring/storage shouldn’t damage it. Its rugged and durable design, and advanced tech, ensure that you can rely on a five-year warranty. One thing we think is worth noting is that it does weigh 21.45kg. Thankfully, however, it comes with carry handles.

MOSEWORTH LiFePO4 Leisure Battery

MOSEWORTH LiFePO4 Leisure Battery

  • Output: 200Ah
  • Size (LxWxH): 522 x 240 x 219mm
  • NCC rating: N/A

Reason to buy:

  • Excellent power, ideal for off-gridders and all-season touring

Reason to avoid:

  • Caravan may need adapting to accommodate the battery

Another super-sized leisure battery that pumps out huge power. With this cell and the Renogy, check that they can be safely accommodated in your caravan. Serious off-gridders that love this sort of power reserve often adapt spaces in their vans to hold them.

This unit comes with a charger unit and a two-year warranty, the manufacturers also claim it delivers 90% efficiency even in cold weather. We like how this makes it ideal for all-season touring, and winter periods when solar panels are less effective.

The energy density of lithium batteries is exceptional, so they’re great for heavy draw appliances, like motor movers and AC units.

Amerrly 100Ah LiFePO4

Amerrly 100Ah LiFePO4

  • Output: 100Ah
  • Size (LxWxH): 330 x 173 x 236mm
  • NCC rating: N/A

Reason to buy:

  • Straightforward to fit, good lifespan, relatively lightweight at 10.2kg

Reason to avoid:

  • Lower output than other lithium batteries in our guide

This lithium leisure battery is a standard size, so won’t have any of the fitting issues you may get with larger units. It also weighs just 10.2kg, so won’t subtract much usable weight from your tourer’s payload allowance.

The Amerrly battery delivers 100Ah with a nominal voltage of 12.8V. Of course, as lithium cells can be safely discharged to a much greater extent than lead-acid ones, you should get up to 30% extra output from this battery compared to a standard one. Plus, lithium batteries can be recharged more quickly.

Expect 3000 charging cycles and a 10-year lifetime from this unit, and when in storage the makers claim it will lose only 20% charge over eight months. For those requiring a large powerbank of leisure batteries, up to four of these units can be linked in series.

Choosing the best leisure battery for a caravan

What are the NCC ratings about?

The three NCC ratings indicate the following:

  • Class A – Ideal for frequent off-grid use, when hook-up isn’t available. These are powerful units that hold a lot of charge.
  • Class B – Designed for use with electric hook-up connections, as they can only support minimal use of light, pumps and motor movers, etc.
  • Class C – For hook-up use only, though they hold enough power to run low-draw items, such as LED lighting.

How long does a caravan leisure battery last?

This very much depends on the level of usage, your recharging regime and the quality of the battery you buy.

You can severely damage or even ruin leisure batteries by over-discharging them. Typically, you should not discharge a lead-acid battery below 50% (12.06V), though I would be wary of dropping below 60% (12.2V). NB: A full battery displays 12.6 or 12.7V.

A good quality, well-maintained standard leisure battery that is regularly used should last from four to five years. A lithium battery can last in excess of 10 years, though, as they are relatively new tech, we’re only finding out now how long they actually last in real-world caravanning scenarios.

Does a caravan leisure battery charge when towing?

With most caravans using modern 13-pin towbar electrics (standard since 2008), your leisure battery is charged from the tow-vehicle’s alternator while the caravan is being towed. The alternator charges the tow-vehicle starter battery and the leisure vehicle battery. The charge is delivered through pin No 9 in the electric connector socket. If you have issues with low-battery charge after a long tow, check that these connections are clean and not corroded.
