How To Choose The Best RV Battery Tender?

You need to take the following things into consideration when hunting for the finest RV battery charger:

What Kind Of Battery Does Your Vehicle Use?

There are two distinct categories of batteries, namely:

Standard engines require a large amount of power to be supplied in a relatively short amount of time, and starter batteries provide this. After that, it is charged by means of an alternator.

The life of starter batteries is not shortened by numerous discharges or draining, as can happen with other battery type.

On the other hand, deep-cycle batteries provide a constant current that is produced over a prolonged length of time. As a consequence of this, these batteries may undergo repeated discharges or recharges without being harmed in any way.

Battery Type

On the market nowadays, you may get a variety of various types of RV battery tenders, which include the following:

The most common sort of chargers is known as converters. It transforms the 120V AC electricity from the shore into 12V DC power.

The majority of people who own RVs choose the more contemporary form of chargers known as inverter chargers. It is a battery charger that features many charging stages all in one package. These chargers take a 12V battery and generate 120V of alternating current.

Solar-powered chargers are a relatively new sort of charger, in which the only thing necessary for the conversion of sunshine into energy is sunlight itself.

Converter chargers

The most fundamental kind of battery charger for an RV is called a converter charger. Since this type of charger changes the 120 volts of shore power into 12 volts of DC electricity, your RV battery won’t need to supply DC power when it’s plugged in because the charger will do that for you.

You may prevent overcharging the RV battery and the associated risk of damage by using a converter charger, which also has the function of charging the battery in the RV when it has the capacity to spare. A converter charger may have a single stage or many stages depending on its configuration.

Inverter chargers

The overwhelming majority of conventional RVs are equipped with charging systems that incorporate inverter technology.

One of the most noteworthy distinctions between this battery tyocharger and a converter charger is that an inverter charger is able to generate 120 volts of alternating current from a 12-volt battery even when there is no connectivity to shore power.

This is the case when the converter charger is not in use. Chargers that use inverters are almost often equipped with many stages of charging as well.

Solar power chargers

Solar-powered chargers are another alternative for you to take into account while searching for a new battery pack. Solar-powered RV battery chargers are a comparatively recent technology that can supply a continual trickle of power.

These chargers are powered only by the sun and are able to do so. These chargers integrate solar panels that take in light from the sun and transform it into usable power that may be sent to you and your RV battery in varying concentrations, depending on your needs.

The wattage of the charger will decide how much electricity it is able to provide; for instance, a solar-powered charger with a solar panel that is 150 watts should be able to provide power to your RV and the gadgets in it for an entire day.

Top Brands

1. Noco

It is difficult to recommend anybody other than Noco battery charger as a source for RV battery chargers. Products such as the Noco Genuis10 Fully Automatic Smart Battery Charger and the Noco Genius5 Fully Automatic Smart Battery Charger are two examples of the innovative and high-quality battery chargers, jump starters, and portable power devices that Noco has been developing and manufacturing ever since the company was founded in 1914.

2. Stanley

Stanley is one of the most well-known brand names in the tool industry, and its products may be found in the toolboxes and garages of many homes.

Because it has been in business since 1843 and has a track record of producing products that are both long-lasting and efficient, this company has an amazing name that has been based on more than a century’s worth of quality and dependability.

Deep cycle battery chargers made by Stanley, such as the Stanley Smart 12V Battery Charger, build on the company’s stellar reputation and provide practical solutions that last.

3. PowerMax AC To DC Converters

PowerMax is a brand that specializes in the distribution of battery power for recreational vehicles (RVs). Since 2005, this Florida-based firm has been meeting the power supply requirements of campers with high-capacity and energy-efficient RV battery chargers, converters, and other items.

Products such as the PowerMax Power Supply Converter Charger for RVs guarantee that you are purchasing a charger that has been specifically designed for use with RVs.

Battery Power

When shopping for an RV battery charger, the battery capacity should be your top priority consideration above all others.

The amount of amp-hours that your battery can deliver is a good indicator of its overall capacity. You’ll need a charger that can handle the higher power that larger-capacity batteries may give, as well as the greater capacity of the batteries themselves.

The bigger the battery, the greater the power output requirement will be for the charger.


You also need to give some consideration to the voltage, which is an important characteristic. For your RV battery to be charged, you need a charger that has the same or a higher voltage capacity as the battery itself.

Although the voltage of most RV batteries is 12 volts, it is essential to verify that the voltage of your battery and the voltage of the chargers are compatible with one another before using either one.

Vibration Dampening

Additionally, you need to consider whether or not the RV battery charger has any form of vibration absorption built in. Vibrations have the potential to interrupt or disturb the charging process, which can occur whether you are on the road or using your battery charger at a campsite.

Hoists and padding are two examples of features that might assist avoid harm to the charger and potential difficulties when it is being used.

Various Charging Rates

Several Varying Speeds of Charging When looking for a battery charger for your RV, be critical to consider both the amp capacity of the device and the kinds of batteries it can charge.

Some are capable of charging at currents of 10 to 15 amps, while others require just 2 amps. These elements will serve as the basis for determining the charging speed, also known as the amount of time required to get a full charge once more.

Cooling-Down Time

A time for calming down. Keep in mind that certain RV deep cycle battery chargers may only be used once and then need to be replaced.

In order to avoid potential damage, overheating, or any number of other issues, certain kinds, such as best deep cycle battery chargers, have to be allowed to cool down for a while before they can be used again.

Maintaining Charging Power

The flexibility of smart chargers to monitor the regulation of the charging power of the battery is an advantageous feature that is beneficial when comparing various solutions, such as an Optima battery charger or any other.

Since a depleted or lifeless battery is something that no one wants, having this function available in our battery charger may be really helpful. It has to be able to monitor or keep track of the current charge battery status.

Even though it could cost us more than purchasing an ordinary charger, we might discover that it is more beneficial in the long run since the charger will also be able to supply power to the battery on its own if it detects that the battery has a low charge state.

If you don’t additionally want to monitor the batterystatus manually from time to time, you could find it useful rather than having to do so manually.

Durability and Maintenance

When making an investment in deep cycle battery chargers, it is important to select models that are both long-lasting and sturdy.

Because it is not possible to make repeated purchases of the commodity, purchasing it is an isolated occurrence. Therefore, it is imperative that you select a product that requires little care and is very long-lasting.

External Protections

A battery charger is an excellent choice since it provides safety and protection to the battery it is charging.

Therefore, it is important to select a product that comes with the ability to absorb shock, vibrations, and a great deal more. The next step is to choose the RV battery charger, which guards against short circuits.

Weather Tolerance

Although we should be prepared for the likelihood that these items will have a more expensive price tag, we also need to be conscious that this aspect also has something to do with the longevity of the battery charger.

It will be helpful if we are able to consider the amount of sun and rain that will be present in our decisions.

Therefore, while we are reading reviews, such as a review of a Schumacher battery charger, we should also check for factors like the weather resistance of the device because it has to do with the charger’s endurance.

Because we plan to use it in our recreational vehicle, we need to examine whether or not it can also be used outside. After all, we need one to catch pace with our camping demands just as we do when looking for other RV items, and we can get one from a camping supply store.

The capacity of the product to withstand water and ultraviolet radiation is one of the things to look for to ensure that it will last a long time. In a nutshell, we need to be able to investigate a product that is resilient or adaptable enough to withstand variations in the weather, such as rainfall.


Equalizer capabilities are a must-have for any RV battery charger worth it’s salt. This is a useful addition since it indicates that the device can make your battery live longer by balancing its charge and reversing the harm caused by isolation. This makes the gadget a beneficial addition.

As you may think, this function is quite necessary in order to get the most out of a charger. However, the addition of this function is another factor that might drive up the total cost. Having said that, I don’t believe there is anyone who could argue that it isn’t worth it.

If I were being really honest, I’d recommend purchasing an option that comes with this ability over any other deal that’s currently available. However, if you can manage to discover a deal that has the equalizing feature, then this circumstance is a dream come true for purchasers. You shouldn’t have any second thoughts about buying the charger

Tips For Efficiently Charging A Deep Cycle Battery

Like any other component in an engine, deep cycle batteries need regular maintenance to function at peak efficiency. Your careless use can drastically shorten the battery’s life, rendering it useless far sooner than planned.

Keep an Eye on the Battery Life: Always keep a check on the battery’s charge while utilizing a deep cycle battery to prevent completely unexpected blackouts. Always start charging when the battery is at least half full to extend the life of the battery in your automobile.

If for any reason you are unable to charge the deep cycle battery to its full 50% capacity, make sure it is never below 20%. If you follow these instructions, you may get a lot of use out of your battery. A voltage monitor, hydrometer, or battery charger amp meter can all be used to determine the battery’s charge.

Keep Sulfate Corrosion at Bay: Deep cycle batteries, like lead-acid batteries, can develop sulfation if they go for a lengthy period of time without being charged. It occurs when lead sulfate crystallizes inside a battery cell.

Once that happens, the battery won’t work again no matter how long you charge it or how far you carry the battery pack horizontally in an attempt to discover a solution to the problem.

You may avoid this by remembering to charge the deep cycle battery periodically, even when it is not in use. Additionally, various anti-sulfation tools are commercially available. Pulses are used to both stop and reverse the sulfation that develops on battery connections.

This pulsating assistance can effectively lessen sulfation on a well-maintained battery. However, it is unable to remedy the situation after it has already developed. And when sulphation sets in, there’s no way to reverse it except to stop using the battery altogether.

Allow the Battery to Rest: The battery may get hot after prolonged use or charging, so be sure to give it time to cool down. Corrosion from direct use might eventually kill the battery.

Learn How to Keep the Battery at a Healthy Level of Charge: Improving the long-term performance of a deep cycle battery requires charging it properly and with a suitable deep cycle charger. Whatever the situation may be, overcharging and undercharging both lead to eventual battery failure.

Battery swelling and uncontrolled gas leakage are the results of structural degradation brought on by excessive deep cycle charging. To sum up, overcharging a single battery has no negative effect on its longevity. If you keep doing this, your automobile battery will eventually die of total and utter tranquillity.

On the other hand, if you charge the battery below the minimum required level too often, it may never recover from being completely discharged.

If you only ever charge it to 80%, for example, the battery will never be able to take a full charge again, regardless of how long you leave the charger plugged in. This will drastically reduce the battery’s initial capacity and limit its expected lifespan.

In addition, charging the deep cycle battery outside or in a lightly large area without a sealed ceiling will help you perfect the procedure from head to toe. Charging a deep cycle battery indoors is a worry for many. It’s true that traveling this route might provide some potential threats.

Due to the fact that the battery’s vapors might accumulate and cause discomfort in confined spaces. Even worse, you may have breathing difficulties and be put in a potentially life-threatening situation. More than only the battery might be harmed if things go wrong too quickly and an explosion happens.

How Do You Use A Battery Tender on an RV?

There is more to maintaining your RV’s battery than just attaching the wires. It is necessary for you to carry out each step exactly as described in the guide. When operating a battery charger on an RV, the following procedures should be followed as a rough reference.

  1. Take the wire harness and detach them from their connections. Begin by connecting the negative cable, which is black, then go on to the positive cable, which is red.
  2. Put the tender in neutral and unplug it from any outlets that use electricity.
  3. Join the battery’s positive terminal to the positive tender cord, and the battery’s negative terminal to the negative tender cord.
  4. Determine the rate at which you wish the RV battery to be charged. You must also decide whether the battery charger will run for a specified period of time or whether it will power off by itself after the battery is fully charged.
  5. Once you have the battery charger set up, you should not meddle with it.
  6. As soon as the battery has been charged to its greatest potential, turn off and disconnect the battery charger.
  7. Unplug the wires, first with the negative ones, then move on to the positive ones

Can You Use a Trickle Charger on An RV Battery?

The charger that is attached to the RV’s battery may be employed effectively. It is an ideal form for charging lead-acid batteries. This charger gives your battery a gradual and steady charge.

What Is the Difference Between a Battery Tender And A Battery Maintainer?

The charging of the battery is also maintained by battery tenders, which prevents the battery from being overcharged. In addition, the battery tenders will turn off by themselves after the battery has been charged to its maximum battery capacity.

On the other hand, battery maintainers ensure that the battery stays completely charged while also extending its lifespan. When the battery has reached its capacity, the charging mode will automatically change to float mode so that it can keep its full charge.

Can You Leave a Battery Tender on All the Time?

Affirmative! But you will need to keep a close eye on the condition of your home’s batteries. Keep a close eye on the amount of electrolyte that is present in your batteries on a monthly basis.

Can You Start a Car with A Battery Charger Connected?

It is possible to start the vehicle while the battery charger is still connected. To begin, you will need to check that the wires are not impeded in any way by any of the moving elements.

Why are RV batteries different?

In addition to providing greater power than many other types of batteries, these batteries are also lighter and more compact than lead-acid batteries.

What is the most way to charge RV batteries?

The best way to charge an RV battery is simple. In fact, the process usually entails the following five measures. Before we get into this, though, let’s quickly review the tools you’ll need:

Equipment Needed: 
Battery Charger
Equipment Needed: 
Pure Distilled Water
Wrench with a Flat Head

Now that you have everything you need, let’s go over the procedure:

1. Take out the battery and transfer it somewhere that isn’t too humid or crowded.

2. To get to the vehicle batteries, get out your flathead screwdriver and scrape off the protective covers. This protection might come in the shape of several plugs or a single, huge cap that fits over the entire battery. During this process, you should always use protective equipment, especially goggles and gloves made of rubber. In the process of removing the lid, the acid contained within the cells may splash out.

3. Take out your hydrometer and insert its tip inside the cell, then inject some fluid. Follow the included directions to interpret the results from the hydrometer. To indicate whether or not the cells are dehydrated, some of them may employ floating balls. They’ll use a needle gauge, which is what most people will have. You have to have the right amount of water in the cell for the battery to function properly. Distilled water should be added if it is determined that the cell is dehydrated. After making sure all of the cells are adequately hydrated, you may seal them.

4. Find your device’s deep cycle charger and switch it to the slowest battery charging setting. Also, decide if you want to charge a battery that operates on 6, 12, or 24 volts. If your battery charger has a battery voltage setting, you should use a voltage of 20% of the battery’s amp-hour rating for battery charging. You may find this number on the top or side of your battery.

5. Following this, attach the charger’s wires to the battery’s terminal posts. When connecting a cable, always start with the positive end and the positive terminal. Positive terminals are easily identifiable because they have a plus symbol or are colored red. Then, switch to the negative cable and terminal and repeat the process.

Plug in both ends, then power up your charger. After 20 minutes, check the status of your charger’s indicator light. If you wait that long, you should get a true representation of your battery’s charge. If your charger has a built-in voltage regulator, it will automatically turn off once the battery reaches the target voltage. In the absence of such a device, however, you will need to check the battery charge meter every hour until it reads 100%. And when the power supply is reached it’s maximum, turn it off.

What is the better battery maintainer or a trickle charger?

In contrast to battery maintainers, which can remain plugged in even after the battery is fully charged, chargers should be unplugged after the charging process is complete. Keep in mind that “smart” battery maintainers won’t provide more charge to a battery that’s already at 100%.

Does plugging in an RV charge the battery?

The good news is that the answer is “absolutely,” and the house battery in your RV will charge when it is connected to shore power. When an external power source is connected to your RV and gives electricity to it, the battery in your RV will begin to charge.

What is the difference between a battery charger and a battery maintainer?

The fundamental contrast between a battery charger and a battery maintainer is that a charger applies a consistent charge until it is finished, which implies that it needs to be disconnected once the battery has been fully charged.

A battery maintainer, on the other hand, does not apply a constant charge until it is finished. Because of this, deep cycle battery chargers cannot have their connections left active while they are unattended for extended periods of time.
