What Kind of Battery Should I Get For My Travel Trailer

This section is about the different types of batteries. There are three main types of batteries used in travel trailers: deep cycle, lead acid, and lithium ion.

The first type of battery is a deep cycle battery which has a lot more power than the other two types because it can be discharged more times than the other two. Deep cycle batteries are often used for trolling motors and some recreational vehicles. The second type of battery is lead acid which is also often used for trolling motors as well as golf carts and some recreational vehicles. The third type of battery is lithium ion which has a lot more power than the other two but also costs more. Lithium ion batteries are often used for electric cars and some electric bikes because they don’t discharge as quickly as lead acid or deep cycle batteries do.

Should you keep your camper plugged in all the time?

Should you disconnect RV battery when plugged in?

Parasitic loads like gas detectors, clocks, and other small electrical devices drain power when your RV isn’t in use. If the power gets too low, it can hurt battery life. Your RV should be equipped with battery disconnect switches to prevent this, so don’t forget to engage them when the RV is off or in storage.[6]

How do I know what kind of battery I need?

The battery case will usually have the battery’s name and manufacturing number. If you search the sides of your battery, you’ll likely find the battery type. The battery label will say which type of battery it is. Since labels are often more about branding than informing, you may not find the battery type on the label.[7]

Are lithium batteries better for RVs?

A lithium battery will be lighter, more efficient, and more powerful than lead acid. And while they cost more, they also last much much longer, so they save you money over time. Because of all these factors, lithium RV batteries are the best choice for most RVers.[8]
