How to find the best motorhome battery for you

Which Leisure battery do I need?

The time has come for all adventurers to seize the day and see the world. But first, you need to make sure everything is in check for your Summertime travels, including your battery.

Motorhomes are commonly fitted with 2 batteries, one to start the engine like any other vehicle and one to power all leisure applications such as lights, fridges, cookers etc. But it can be tough knowing which battery to choose as it doesn’t tend to be something that most people will frequently look at. There are many factors that could be used to determine which battery you need, such as power, brand, price and more, but you may be asking yourself, which motorhome battery do I need? Below is a guide to the different types of leisure batteries and what they are suited to.

Standard Lead Acid Batteries

For smaller motorhomes that don’t have many applications running off of them, a smaller 685 size battery will most likely do the job. These batteries are usually around 75-85Ah and are quite small in size. The most common battery found in motorhomes is a 100-110Ah, if you’re unsure about the battery you need to buy, we usually recommend trying one of these. They also come in two different sizes, a standard case and a low case with a lower height designed for fitting in those tighter spaces. These are either NCC Verified class C or just come with no NCC verification. Class C batteries tend to be designed for applications that require low power in order to operate, but don't be put off by the NCC rating or lack of, as a lot of the time a standard lead acid leisure battery can be perfect for motorhomes.

 

Semi Traction Batteries

Semi traction leisure batteries are basically an upgrade to a standard deep cycle battery, these batteries are able to provide a higher number of cycles meaning more power for your applications. Semi traction batteries usually range from 6 and 12v and from 85Ah all the way up to 250Ah, so if you think a standard 85Ah battery won’t cut it but don’t have enough room for a 110Ah, you could go for a semi traction 85Ah battery. Or if you don’t think a standard 110Ah battery can power your motorhomes applications, you could consider a higher Ah semi traction battery.

 

EFB, AGM and Gel Batteries

For some people, buying the battery itself should be the last concern when it comes to motorhome batteries, however sometimes batteries may need to be maintained and topped up with deionised water. With EFB, AGM & gel batteries this aspect is completely eliminated by their maintenance free design. Plus they are an upgrade from a standard lead acid battery anyway, so it’s a win win. EFB batteries are usually class C verified, while AGM and gel batteries are commonly class B or A as they require a higher battery capacity than a class C in order to run applications such as motor movers.

 

Lithium Batteries

Finally, we come to lithium batteries. Lithium leisure batteries are quite a bit more expensive than lead acid batteries, but their price is well and truly justified by their results. Applications running off of a 12v battery will begin to lose power when the battery drops to around 10.7v, this is the same for lead acid and lithium, however, whereas the lead acid battery will use around 40-50% of its power before getting down to 10.7v, the lithium will use around 97% of its power meaning it can last pretty much double the time than that of a lead acid. Still not convinced? Well, some lithium batteries have the ability to charge within just a couple of hours, sometimes even less! They are also maintenance free and much lighter than any of the previously mentioned batteries, and we all know how heavy leisure batteries can be. In short, a lithium battery would be a massive upgrade from any of the battery types above, however, it could be seen as slightly overkill if you're only using the battery to power a few lights.

 

So in conclusion:

  • If you don’t have many applications to run, go for a smaller 85Ah battery.
  • If you’re unsure but know that a smaller battery won't work, opt for a 110Ah battery.
  • If you know what you need but just need more power try a semi traction battery.
  • If you want a battery that’s hassle free or just want an upgrade, go for an EFB, AGM or gel.
  • And if you want the best leisure battery that money can buy, a lithium battery is what you need.
