What RV battery do I need for my towable RV?

PA Blog 1

With so many types of batteries available, it can be difficult to know which type you need for your towable. Do you need a large battery that will provide more power, or a battery just for small things? Depending how much power you need, there are various battery sizes – the most common is a group 24 battery and a group 27 battery, also known as “house batteries.” The group 24 battery is a good choice if you are limited on space or only have smaller accessories you need to power.

The most important thing to consider when purchasing a battery for your towable is the amount of power you need. Deep cycle batteries come in all different sizes. Some are designated by group size, like group 24, 27 and 31. The larger the battery the more amp hours you get. The same can be said for the types of batteries you get. Although all group 24 batteries are the same size, the brand of the battery will also make a difference. Some recommended battery brands with the best power span for a towable are Trojan, Interstate and Exide. You can read about the best batteries for your RV here.

With a larger battery also comes more amp hour reserve capacity. If you have more space available to you, a 6-volt battery, also known as a group 29 and 31 battery, will meet your needs. With battery theft a major concern, including a recent growth of battery theft in Canada, how can you protect your investment?

Being in an environment in which I can problem solve is where I flourish. Every answer to a problem leads me to a new concept to understand or a lesson to learn. When I'm not solving problems I enjoy camping and going to festivals with my family - from the local city center festivals to the mountains of Wenatchee at the Winter Grass, blue grass music festival. Experiencing culture is where my heart is content.
