What is the Battery for on a Travel Trailer?


The RV battery is a crucial component for all types of travel trailers. This is because they are often at the core of the trailer’s electrical functionality. Almost every electrical part in a travel trailer can be connected to the battery. Even though it is possible to operate your travel trailer without a battery power source, most trailers still depend on it for facilitating electrical functionalities. 

What is the Battery for on a Travel Trailer?

The battery on a travel trailer provides power all of the items to make your trailer function such as your water pump, heater, refrigerator, lighting, tongue jack, slide out, smoke and propane detectors, and other items. Without a battery, you wouldn’t be able to run any of these items.

Despite all these crucial contributions to the electrical functionality of travel trailers, however, RV owners do not regard their vehicle batteries as much as they ought to. Some of them do not even know much about the RV battery. 

If you own a travel trailer, there are high chances that you do not fully understand the purpose or functions of the battery in your vehicle. Perhaps, you have even asked what the battery on your travel trailer is there for. 

In this article, we will help answer this question and teach you some of the top functions of a battery in your travel trailer. Before that, though, let us see what an RV battery entails: 

What is an RV Battery?

An RV battery, also known as a deep cycle cell, refers to a type of battery that functions for sustained power over a long time. This is the type of cell that is attached to a travel trailer to conveniently supply enough energy for all the electrical components while on a trip. 

Lead acid RV batteries can run reliably and efficiently until it is 50% discharged. Lithium batteries typically can be discharged to 20% or lower. If you are a consistent boondock camper, we recommend these lithium batteries to extend your trip. Whatever the case is, though, you can rest assured that an adequately charged RV battery will provide all the power required by the electrical components of your vehicle while you are on a trip or adventure. 

It is important to note that deep cycle batteries are quite different from other types of vehicle batteries. As such, other types of cells such as a starter battery might not function for your travel trailer as efficiently as a deep cycle battery would. 

What are the Functions of an RV Battery for Your Travel Trailer?

Now that you understand what an RV battery entails, let us see some of the functions it performs in your travel trailer. Of course, the features of a battery in your travel trailer are quite many. However, here are a few important ones you should know: 

  • It functions as a power source to different light systems in your vehicle: This powers your interior and exterior lighting. Without a battery, you will not have a great experience camping in the dark.

They help to illuminate around, and inside the vehicle at night whether you are reading, cooking, or getting ready for the day.

  • It functions as a power source to other electrical components in your vehicle: apart from the different light systems in your travel trailer, RV batteries also supply energy to other electrical components and systems in the trailer. This power supply facilitates the performance of the elements and systems for a seamless experience. The ingredients include tongue jacks, slide outs, electric wheel brakes, etc. 
  • It provides 12-volt DC Power for your vehicle: most of the luxury appliances and lighting systems that are built in your travel trailer require 12-volt DC power to function effectively. Some of these appliances include a fridge, water pump, furnace, slide outs, awnings, lights, etc. RV batteries can also supply this power and maintain their functionalities, even when you park it at a campsite. 
  • It powers your propane and smoke detectors: leak detectors are very vital security components in every vehicle. This is because they help to save the occupants from terrible accident situations. However, they are almost useless if they do not get sufficient power. 

This means that RV batteries play a crucial role in the functionality of your vehicle life safety appliances. Without a battery, your RV’s sensors for carbon monoxide leaks, propane leaks, and fire may not function efficiently. When this happens, your risks of getting into life-threatening accidents are bound to increase significantly. 

  • It helps preserve your groceries and other perishable foods: the whole idea of a travel trailer is to allow passengers to live comfortably inside the vehicle while spending hours or even days on the road. This means that it is built with a provision to carry all the necessary items you will need to survive for days away from home. 

Some of the things you might need will include groceries and food items. Unfortunately, these items are perishable and can get damaged within hours or a few days. With the provision of a refrigerator in your travel trailer, however, you can preserve them to last longer. RV batteries help to make this possible by providing sufficient power for the fridge to function effectively. 

Conclusion 

It is clear that RV batteries are a very crucial component of the travel trailer that performs various vital functions for its smooth operation.
