What is an RV Battery Charger?

As the name suggests, an RV battery charger means a purpose-designed charger used to charge RV batteries. Unlike standard batteries, RV batteries are manufactured using solid and thicker plates, so they should be charged using a dedicated charger.

However, both a traditional battery charger and an RV battery charger work in the same way. It keeps charging the RV battery until it reaches its maximum capacity. However, some models even offer a trickle charge to tackle self-discharge, keeping the battery fully charged.

Benefits of an RV Battery Charger

Besides keeping the batteries charged, there are plenty of benefits of having a dedicated RV battery charger.

Some of the most common benefits include,

1. Extend the Batteries Lifespan

Nothing lasts forever, but with proper maintenance, you can extend the life. If you want to keep your RV battery in its optimum state and extend its lifespan, it’s essential to charge the battery with a quality RV battery charger. It will make sure to not damage or overcharge the battery while making sure you don’t have to replace the battery for many years to come.

This not only helps a lot of effort but your hard-earned money as well.

2. Keep the Appliances in your RV up and Running

Having an RV battery charger with you while on the road, you don’t have to worry about running out of charge. It allows you to keep the battery bank of your recreational vehicle fully charged. With RV batteries at full charge, you could use the appliances without worrying about running out of juice to enjoy all the comfort of your home while traveling.

3. Unlimited Travel Opportunities

Unplanned travels allow you to make your travel more enjoyable and memorable. However, your RV must be equipped with the essentials you will need when traveling for extended periods. By having a battery charger, you can travel off the grid or locations where you don’t have any external power options to charge your RV’s entire electrical system. Moreover, you also don’t need to plan your travels only on those routes that offer charging services. You can travel anywhere and whenever you like.

Now let’s talk about Types of RV battery chargers!

Types of RV Battery Chargers

There are plenty of RV battery types, which are useful to have for the right RV.

1. Converter Chargers

Converter charger is among the most basic RV charger/converter systems that convert 120V shore power into 12V of Direct Current power. Having this charge with you means your RV battery will store the power when you are plugged in. Additionally, the charger can charge your RV batteries when it has excess capacity.

A converter charger is known for its smooth functionality and is calculated in amps. With 55 amps of Direct Current, you can power up almost all the electrical systems and appliances inside your RV while also charging. These chargers interact directly with the main power distribution panel, offering both 12V-12V functionalities in a single unit. It is available both as a single and a multi-stage product.

2. Inverter Chargers

Unlike a converter charger, an inverter charger is available only as a multi-stage product. If you are an owner of a Class A motorhome, you definitely have an inverter charger. However, it is similar to a converter charger in terms of functionality with some additional features. It can produce 120V of Alternative Current from the battery’s 12V where you are not connected to the shore power.

3. Single Stage Chargers

A single-stage charger can be found in the majority of motorhomes, especially if you have an older model. But how does it work? We cannot compare an RV battery to a sponge. They do not just absorb amps and store them. An RV battery has to get a higher voltage as opposed to its capacity to charge itself.

Just like a flat tire, as you inflate it, you have to apply more pressure to fill it. If the pressure is not up to the mark, the tire will throw it back out, making it deflate. That is exactly how an RV battery starts to fill with amp-hours and then start pushing them back upon hitting the maximum capacity.

This is what a single-stage method is, which can be found in motorhomes and low to mid-range trailers battery chargers.

4. Multi-Stage Chargers

Unlike a single-stage charger, the multi-stage charger is a modern method, which can be found in almost all the latest models of travel trailers and motorhomes. It helps optimize charging, considering the three stages of a battery charge: bulk, absorption, and float.

The bulk stage is when you charge a battery from low charge to up to 80% capacity. It will constantly charge the battery at 25% of amp capacity. After hitting a certain level, the battery enters the absorption stage, which is all about balancing the constant flow of volts to the battery until it hits the maximum charge capacity.

After that comes the float mode. It ensures to keep the RV battery fully charge while maintaining a voltage of 13.6 and keeping the battery safe for extended periods.

5. Solar Battery Charger

A majority of RVers are turning to innovative charges to supply power to their entire RV electrical system. RV solar battery charger is a great option if you are also one of them. Smaller solar panels can maintain battery power while not in use. But they require being between 15 to 20 watts.

A larger solar panel between 100 to 150 watts is capable of powering up your entire RV electrical system while also supplying power for a whole day. If you go with 14 voltages, it will cover the 1 amp required to power the battery while not in use. This is something useful since most RVs lose up to 0.25 amps per hour without any external solicitations.

6. Trickle Chargers

Another type of RV battery charger is a trickle charger. It is its responsibility to keep the battery fully charged. These types of charges are usually small and use a single-stage unit. The best aspect of trickle chargers due to technological advancement offers a float charge stage. The charge is set o hold a 12V battery; however, you may see various outputs in some models. Those models can comfortably handle two or more at the same time.

Factors to Consider When Buying the Best RV Battery Charger

RV owners who are looking to buy an RV battery charger have to consider various factors. Below I have discussed each of these factors to ensure you get the best RV battery charger.

1. Cost

Cost is among the most deciding factors when buying a product. Every option features a different price tag than others. So, you should keep a budget around features that you want and that are essential for your RV battery.

Moreover, your budget will also narrow down the choices, making the entire process less stressful. However, the main objective behind having a budget is to find a reasonable option having all the features you are looking for. It is essential to remain realistic about the features you need and the cost of those features.

2. Built Quality

The built quality of an RV battery charge has a lot to do when it comes to your specific needs. You have to think about what designs aspects you want to have in your battery charger to ensure you get the most appropriate option.

Like UV-ray resistance and waterproof capabilities, most chargers built quality makes them usable in outdoor environments. On the flip side, some battery chargers don’t have the potential and cannot be used in extreme situations like snowstorms and rainstorms.

If you are looking for a charge that you can use anywhere you, you should also accept these features to cost more.

3. Battery Type

Another vital aspect to consider when buying the best RV battery charger is your battery type. Some charger options are useful to charge a specific type of battery only. A typical example would be a charger model capable of charging lead-acid batteries but does not work when it comes to gel batteries.

4. Durability

You want an RV battery charger capable of lasting for extended periods. Make sure to avoid buying a product that needs a replacement more often. So, when buying an RV battery charger, find something made from top-tier materials.

5. Battery Size

Another factor to consider is your battery size. It doesn’t mean the physical dimensions of a battery, as one might assume. Instead, it is measure in amp-hours a battery can store. Generally, a battery can store up to 50Ah and takes about six hours to be fully charged using a 10A battery charger.

Final Thoughts

Having the best RV battery charger with you allows you to travel anywhere without worrying about running out of power. Above, I have bucketed five best RV battery chargers that you can have to charge your RV battery bank.
