What Type of Leisure Battery do I Need?

The answer to this question isn’t always straight forward, but if you’re looking for a quick reference there are some hard and fast rules to help you select the right type of leisure battery for your intended use.

Occasional Usage

Light leisure battery usage is almost always defined as occasional weekend caravan, boating and motorhome holidays, usually where fixed power points are available. If that matches your requirements then a dual-purpose leisure battery should suit your needs and you’ll find they’re often competitively priced.

If you need to power a motormover or a large assortment of devices then opt for a 110AH leisure battery or larger to match your power needs.

We’d Recommend:

For occasional usage we always recommend our own brand Xplorer range, it offers amazing value and peace of mind with long 3 & 4 year warranties depending on the model you select.

Regular Usage

For anything other than occasional weekend holidays, such as prolonged or frequent breaks, in situations where a fixed power supply is not available or for those living on narrowboats and in caravans, then you’re almost always going to require a more expensive semi-traction leisure battery.

The construction of these batteries is different to provide the consistent performance over a prolonged period of time required in these situations.

We’d Recommend:

Whilst we also offer an AGM option here, when you need something a little more robust you can’t go wrong with Banner. With high quality construction and performance it’s a brand that’s highly recommended.

How do I Select a New Leisure Battery?

Whilst the application types often vary, leisure batteries themselves often follow similar sizes and power outputs, regardless here are a couple of things worth checking before you head straight to the checkout.

Check the Existing Battery

If you’re not sure what type of battery you need, then our very first suggestion would be to check the existing battery you’re intending to replace.

There’s no certainty that the current battery will be the right fit for your needs, but it’s a good starting point giving you something to work with in terms of capacity and physical battery size.

Measure Your Battery Tray

The problem with replacing like for like is that the current battery might not actually be correct in the first place, hence the need to replace it!

If you’re in any doubt it’s always worth measuring the battery tray or the space your battery needs to fit into as this will provide you the widest option of available replacements.

Consider Your Requirements

If replacing your battery has become all to frequent an occurrence then you may not be selecting a battery that’s suitable for your needs.

Take into consideration how often you use the battery, for occasional use a dual-purpose battery will suffice, but for anything else you’ll need to invest in a semi-traction battery instead.

Back To Top

If you’re only looking for a battery to support occasional weekend trips and the use of a caravan motor-mover, then you’ll be fine with a dual-purpose leisure battery. If you have a few different appliances to run then make sure you select something 110AH or above just to be on the safe side.

Leisure Battery Usage Calculator

The only way to be certain that you’re selecting the perfect battery for your needs is to work out your combined watt value to determine your requirements. We’ve made the process easy with our leisure battery calculator.

Back To Top

It’s a myth that car batteries can’t be used in leisure battery applications, prior to the coining of the term ‘leisure battery’ car starter batteries and even old World War 2 batteries were used for leisure applications. A modern leisure battery will just do a much better job!

Leisure Battery Terminology

Selecting the correct leisure battery isn’t made any easier by the range of terminology applied to leisure battery products. We’ve covered some of the common terms to make sure you’re well prepared.


The voltage is essentially what moves the current around the battery and the majority of our leisure batteries are 12v which will match most if not all modern leisure battery applications.

A small number of semi-traction batteries, such as those by Trojan, also come in a 6v range allowing for the creation of large battery banks.


AH stands for Ampere Hours and relates to the battery’s ability to provide power over certain periods of time, the higher the AH then the longer the battery will be able to provide power.

Battery AH typically increases with actual physical battery size and it is important to strike a balance between the right size battery in terms AH with your actual power requirements and physical size restrictions.


CCA stands for Cold Cranking Amps and relates to the battery’s ability to turn an engine over. If you don’t intend to turn an engine over then you can safely ignore the CCA rating and focus instead on AH.

If you intend to use your battery for starting as well as general leisure use then then look for a higher CCA rating, dual-purpose leisure batteries tend to lend themselves better for this application.


Ultimately capacity refers to how long a battery will last for, but with no formal requirement to list capacity in an universally accepted way, a new European system is being championed by a number of leading manufacturers and this is a system we have also adopted.

The rating is based on three different power ratings over different time periods, for example:

  • 85AH @ 5 Hours
  • 100AH @ 20 Hours
  • 110AH @ 100 Hours

Effectively the above ratings indicate that this product would produce 110AH over a long discharge period, but only 85AH over a shorter space of time.

Cycle / Deep Cycle

A cycle is the number of times a battery can be part discharged by 50% then recharged. The more cycles a battery can do, then the longer the battery should last in the long term, with these products usually termed ‘deep-cycle’ batteries.

To help with discharge levels here is the relation to the percentage of charge and voltage:

  • 12.69 Volts or above = 100% Charged
  • 12.5 Volts = 75% Charged
  • 12.2 Volts = 50% Charged
  • 12.00 Volts = 25% Charged
  • Below 12.00 Volts = 0% Charged (Discharged)

The above can be particularly useful if you have a battery tester to hand.

Calcium Technology

There is a great deal of mis-information associated with Calcium Technology, to put the record straight the technique is used in most, if not all, modern battery production.

The technology is based upon strengthening the lead plates with Calcium and other materials to make them stronger. They do not require different charging voltages and should always be treated as standard lead acid batteries.

Lead Acid

This is the most common type of construction in both dual-purpose and semi-traction leisure batteries. Inside the battery is a solution of water and acid which cover the internal lead plates and they come in sealed and semi-sealed options.

Sealed variants have no function to access the cells and require no topping up sometimes referred to as ‘maintenance free’, semi sealed batteries provide access via six caps on the top of the battery which can be removed to top up the acid levels. Under normal conditions you will never need to access the cells on a leisure battery, however frequent use and deep discharging will cause the solution to evaporate.

Lead acid batteries need to breathe and should never be kept in airtight boxes, they will always have a breather hole on the side which you can attach a vent pipe to for peace of mind.


AGM stands for ‘Absorbent Glass Matt’ and they have the acid solution soaked into material between the lead plates rather than a traditional flooded construction. This results in a battery which is totally spill proof and produces excellent recharge cycles.

These batteries were first used by airlines in the 1970’s to provide onboard power and to replace the wet lead acid systems which had proved unsafe. As manufacturing costs came down this technology was applied to mass produced leisure batteries and they are now popular options.

As with standard lead acid batteries these AGM batteries come in both dual-purpose and semi-traction options with some types requiring venting.


GEL based batteries have the acid solution contained in a gel type paste rather than flooded or soaked on matt.

Generally they tend to be more suited to electric vehicle applications but are ideal options for the most demanding situations such as for solar and other backup power systems.

GEL batteries offer the most recharge cycles of the typical leisure battery technologies, but the range is limited to only a small number of manufacturers and battery types.
