What Size of Battery Does My Trailer Need?

The size of your battery is crucial, but there is no specific answer to this question. It totally depends on the power requirements in your rig, plus the hours you are running each appliance or electronic on board. A larger battery will store and provide more power. Another thing to consider is the space and weight carrying capacity you have available.

The amp hour rating of most batteries helps a user to estimate the amount of power a battery contains. Therefore, you should first determine the power needed and compare the different options available before making a purchase.

How to Choose a Battery For Your Travel Trailer

You will find a huge variety of batteries available on the market, each having its own positives and negatives. Choosing the right battery is important to ensure that your vehicle continues to run as efficiently as you have hoped for. Make your way through this buying guide to select the right product for you.

Capacity

The capacity of a battery is rated in Ampere-hours (Ah), and it helps to determine how much current the battery can deliver over time. Choosing a high capacity battery is ideal as it can serve longer and store more power.

Depth of Discharge

This is normally expressed in percentage and refers to the amount of power discharged by the battery. It is recommended to look for a deep cycle battery with a depth of discharge that, when followed, optimizes its life cycle.

Power Requirements

Another critical element to consider is the power requirement. It is important to look at the CA (Cranking Amps) and CAA (Cold-Cranking Amps) to access its tendency to start engines at variable temperatures.

Maintenance

Travel trailer batteries are categorized into low maintenance and maintenance-free. Maintenance-free batteries are sealed with an electrolyte flowing through them on its own. Conversely, their low maintenance counterparts have unsealed caps which are used for water filling.

Voltage

This factor refers to the electric potential difference, which is typically 12V for a starter as well as deep cycle batteries. Some users combine 6V batteries to construct a 12V battery for RV use.  Similarly, some solar kits and other chargers can also work with 24V batteries. You might need a power converter to convert DC to AC current in order to perfectly fit your battery.

People Also Ask

In this section, we've attempted to answer some questions RV users may have about these batteries. All travel trailers require a different type of battery. Plus, every model has variable requirements in overall power and size.

How to Charge a Travel Trailer Battery?

Most recreational vehicles come with a charging system for batteries. However, some of them are unable to deliver good performance. One of the best is the converter charger that has the purpose of converting 120V shore power into 120DC. Moreover, you can always charge your battery by employing a generator or a solar panel.

How Long Does it Take to Charge My Travel Trailer Battery?

The length of time to charge the battery depends on how much it has been used. Plus, it also depends on the amperage of your onboard charger.  For example, charging at 15 Amp would take 9.6 hours. Similarly, under full sun conditions, using a 100-watt solar panel would take over 28 hours to charge your battery.

Will a Generator Charge One of These Batteries?

Yes, you can go for a generator to charge these batteries. In case you opt for a generator to charge RV battery, you must follow some steps. First of all, you need to fully charge the generator or plug it into an AC outlet, which runs at 120 Volts. Maximize the charging process by turning off the recreational vehicle. Plug your RV into the generator, and it might take max 2 hours to charge the battery fully.

Should I Leave My Camper Plugged in All Winter?

Yes, you should leave your camper plugged in during winter as disconnecting your battery won’t be feasible. New models come with different gadgets or devices in them, and disconnection will only increase the problem. The only thing you should monitor is the electrolyte level of the batteries to make sure that they have not gone dry.

What Are The Different Types of Batteries?

A single battery type is not suitable for all trailers.

Flooded or wet RV batteries are quite famous for their low price, and are usable as long as their internal fluid lasts. The most common type of batteries used in RVs is deep cycle batteries because of their longer lifespan and durability.

Another type is the Lithium-ion battery, which is lightweight, highly reliable, and maintenance free. Moreover, VLRA batteries are equipped with regulated lead acid and safety valves.

How Long Will a Battery Last?

The lifespan of an RV battery is dependent on its usage. It can last for up to 5 years approximately if given proper maintenance. You must consume your battery completely similar to a marine battery. Another thing to monitor is the electrolyte level; your battery might fail prematurely in case of a low level of electrolyte, also preventing the overfilling.
