Now for more general information on travel trailer batteries. Here you'll learn what features to look for in a good quality device and exactly which size battery you'll need for your set up. We also look at the tell tale signs of when it's likely time to replace your old battery.
We also look at the different types of batteries available for RVs, and offer a step-by-step guide on how to install one. There's an FAQ section to wrap things up so you should know all there is to know about RV batteries by the end of the article.
What Size Battery Does My Travel Trailer Need?
The size of your travel trailer battery is crucial, but there's no specific answer to this question. It all depends on the power requirements in your rig, plus the hours you're running each appliance or electronic on board. A larger battery will store and provide more power, and always consider the space and weight carrying capacity you have available.
The amp hour rating of most batteries helps a user estimate the amount of power a battery contains. So, you should first determine the power needed and compare the different options available before making a purchase.
When Is It Time to Replace My Travel Trailer Battery?
If a deep-cycle battery is properly maintained, then it can last for more than six years. However, some RVers replace their RV’s batteries every one or two years. You’ll need to replace your battery if it reads 0 volts, as it can be a sign of a short circuit. If your battery is unable to reach higher than 10.5V when it’s being charged, then it has a dead cell and needs to be replaced.
Lastly, if you have a fully charged RV battery, but have a voltage of 12.5 or less, then it's sulfated, and it’s better to install a new one.
How to Choose a Battery For Your Travel Trailer
You'll find a huge variety of travel trailer batteries available on the market, each having its own positives and negatives (no pun intended). 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 travel trailer battery can deliver over time. Choosing one with a high capacity 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's 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's 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 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.
Are Travel Trailer Batteries Universal?
Yes, travel trailer batteries are universal. Along with providing power for RVs, they can be used with smaller vehicles, like electric wheelchairs, bikes, boats, and scooters. However, since travel trailers consume more power than passenger cars and small vans, it’s advisable to choose a deep cycle battery that’s specifically designed for travel trailers.
A good travel trailer battery should be lightweight and compact and should have enough power to handle all your electrical needs. These batteries are an excellent backup power source for portable generators and solar applications as well.
What Are The Different Types of Travel Trailer Batteries?
A single battery type is not suitable for all trailers.
Flooded or wet RV batteries are well-known 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. VLRA (valve-regulated lead-acid) batteries are equipped with regulated lead acid and safety valves.
Is There a Difference Between a Deep Cycle And Marine Battery?
A marine battery is a combination of deep cycle and starting batteries. However, the main difference between a marine and a deep cycle battery are the plates. Deep cycle batteries are designed with solid lead batteries, while marine batteries feature lead sponge plates that are thinner than deep cycle battery plates.
How to Install a Travel Trailer Battery
Installing a travel trailer battery can be a difficult task, but after some instruction and practice, it should become easier. Following are the steps you can follow when installing a new battery:
- Switch off the power draw, including all accessories and lights. Make sure the negative cable doesn't spark during removal.
- Remember the battery’s position in the tray regarding the polarity.
- Disconnect the negative cable and then the positive cable.
- Remove the old unit and ensure that the hold-down hardware and carrier are corrosion-free.
- If you’re not installing a maintenance-free battery, then make sure that the new battery has the right amount of electrolytes. To increase electrolyte levels, you just need to add distilled water until you reach the correct volume.
- Use a wire brush to thoroughly clean both terminal posts.
- Install the new battery in the same position for polarity as the previous unit.
- Connect cables to the new battery.
- Screw in the hold-down hardware.
- Test all RV lights and appliances.

How to Test My Travel Trailer Battery
You can check whether the circuit of your travel trailer battery has any electricity with a multimeter. Switch the motor off and check whether the alternator is charging the battery. If the voltage is somewhere near 12V and jumps to 13.8V when you switch on the motor, then the charging system is working fine.
If you own flooded batteries, then make sure you check if the water is at the correct level. Lastly, you should completely charge your battery and then measure open-circuit voltage.
Does My Travel Trailer Battery Charge While Driving?
Most vehicles pulling a travel trailer will charge the trailer battery when driving. However, they cannot completely charge a depleted trailer battery. Thus, you’ll only have a partially charged battery.
How to Charge a Travel Trailer Battery
Most recreational vehicles come with a charging system for batteries. However, some of them don't deliver good performance. One of the best is the converter charger that has the purpose of converting 120V shore power into 120DC. What's more, 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?
it really depends on how much it has been used, and 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, a generator can 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 should 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 haven't gone dry.
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 TLC. 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.
