RV Battery Charger Types
#1. Converter Chargers
The most fundamental kind of RV battery charger is a converter charger.
By converting 120 volts of shore power to 12 volts of DC electricity, this kind of charger eliminates the requirement for your RV battery to provide DC power while it is plugged in.
In order to prevent overcharging and possible damage, a converter charger may also be used to charge the RV battery while it has extra capacity.
Either a single-stage charger or a multi-stage charger may be used with a converter.
#2. Inverter Chargers
The sort of charger used by the majority of contemporary RVs is an inverter charger.
The only major difference between this sort of battery charger and a converter charger is that an inverter charger may convert a 12-volt battery into 120 volts of alternating current in the absence of shore power.
Usually, inverter chargers also function as multi-stage chargers.
#3. Solar-Powered Chargers
A solar-powered charger is another option you might take into consideration.
Solar-powered RV battery chargers are a relatively new alternative that may provide a steady stream of electricity using just sunshine.
These chargers have solar panels that take in light from the sun and transform it into energy that may provide you and your RV batteries with different levels of power.
The amount of electricity the charger can provide will depend on its wattage; for instance, a solar-powered charger with a 150-watt solar panel should be able to run your RV and its appliances for a whole day.

Which Charger Works Best With Deep-cycle Batteries?
Any charger in our product review section is a potential candidate for the title of the best deep-cycle battery charger.
The one that really made an impact on me, though, was the NOCO Genius G15000 12V/24V Pro-Series Battery Charger and Maintainer.
This gadget seems to be more than capable of maintaining the health of your deep-cycle battery.
The cost is a touch high, but given its performance and adaptability, it is well worth the additional money.
Are Special Chargers Required For Deep-cycle Batteries?
Deep cycle batteries sometimes lose enough charge to not be able to power an RV, gadget, or watercraft.
They need to be recharged using a specific charger to get the battery voltage back to where it should be.
As you can see from our post, there are many of these unique chargers on the market right now.
However, using the knowledge you’ve gained here should make the decision rather simple.
Why you won’t soon be properly charging your RV batteries is beyond my comprehension.
How Can I Read An AMP Meter On A Battery Charger?
Contrary to popular belief, reading an amp meter on a battery charger is more difficult.
However, I’ll guide you through the procedure to make it simple.
- Find some gloves, goggles, and other safety equipment, and put them on.
- Locate the plug where you will insert your battery charger.
- Set the amp meter to on.
- When it is switched on, there should be some apparent movement, such as the needle bouncing back and forth. If you don’t see this motion, your battery charger amp meter is definitely malfunctioning.
- After being connected in, your amp meter will then require a few seconds to adjust itself.
- If yours isn’t yielding results straight immediately, don’t be alarmed.
- It’s a typical step in the procedure.
- Next, choose one of the two amp settings on your charger.
- To choose the optimum charge rate for your battery, check the label or manual.
- If everything is done properly, you should observe the needle advancing toward the desired amp setting.
- The battery amp meter on your battery will keep decreasing until it hits zero.
- The charge is complete when the needle or indicator hits zero.
- The ideal amp charger for deep-cycle batteries
- One with 6 amps or more is often the best battery charger for charging deep-cycle batteries.
- But it will switch from one battery to another.
- It shouldn’t be difficult to locate a charger with the right amps if that’s your only worry.
- The majority of manufacturers make it simple by including the details directly in the product description.
Will A Deep Cycle Battery Be Charged By A Battery Tender?
Deep cycle batteries are among the many battery types that Battery Tender battery chargers are designed to maintain and charge.
Owners of recreational vehicles who use them seasonally rather than year-round tend to favor these options.
Your rig’s battery will remain in good condition during those months of storage if you use a Battery Tender battery charger.
It will provide this crucial advantage without having the possible negative consequences brought on by several trickle chargers.
Do Deep-cycle Batteries Respond To Trickle Chargers?
Trickle chargers shouldn’t be used on deep cycle batteries, according to experts.
These gadgets are more often used to top up the batteries in cars and other vehicles with thin plates.
As a result, a trickle charge wouldn’t work well with the deeper cycle batteries’ thicker plate architecture.
Your battery will only sustain long-term harm, which is undesirable for everyone.
Finding a deep cycle charger, such as a premium equalizing battery charger, that is designed to operate efficiently with those bigger plates is thus the ideal option.
If not, the process will only have unneeded effects.
Is A Fast Charge Of A Deep Cycle Battery Acceptable?
Some deep cycle batteries can be fast charged.
For instance, quick charging works nicely with flooded style kinds.
Fast charging is not recommended for GEL or AGM choices since it might reduce the lifetime of such batteries.
How Quickly Can A Deep-cycle Battery Be Charged?
Deep cycle batteries need different amounts of time to charge depending on your charger, the outside temperature, and the size of the battery.
For example, a 100AH battery at an ambient temperature typically needs 5–6 hours to charge to 80% of its capacity.
How did I get at this timeline? I calculated the estimated charging time for the battery by dividing its capacity by the rating of my charger.
It’s important to keep in mind that dirty terminals and cooler temperatures can prolong your charging times.
How Do I Use It?
It’s not difficult to charge deep-cycle batteries using one of these devices.
I’m going to walk you through the process to make it even simpler.
But before that, we need to make sure you have everything you need for the job, including a charger, battery, hydrometer, gloves, some distilled water, a flat-headed screwdriver, and safety goggles.
It’s time to begin the procedure after obtaining these materials:
- Take out your battery and put it somewhere clean, dry, and not too crowded or stuffy.
- Remove the cell covers using your flat-headed screwdriver. Either a huge cap that completely encloses the cells or individual plugs will serve as these devices. Rubber gloves and eye protection goggles or glasses are essential for this technique. These cells’ internal acid has been known to occasionally splash out.
- The hydrometer should be removed, placed in a battery cell, and filled with fluid. Follow the provided instructions to continue examining the hydrometer’s findings. When detecting if there is insufficient water in the cells, these devices sometimes use floating balls. As an alternative, some other models will employ a needle gauge. Add the appropriate amount of distilled water if there isn’t enough water already in the cell. Make sure that each cell contains enough water, then gently recap the cells.
- Get your charger out and set it to drip or slow charge. Additionally, you must choose the proper battery type—6V, 12V, or 24V. If your model allows you to select the charging voltage, I’d advise making sure it’s 20% of your battery’s AH (amp-hour) rating. The battery’s top or one of its sides will display this rating.
- The next step is to connect the cords of your charger to the terminal posts. The positive cable should be connected to the positive terminal first. These positive sides will be marked with a + sign or red wire coloring, making them simple to spot. Then you may repeat this procedure with the undesirable elements.
- It’s time to turn on the charger once both have been connected. To check the charge meter, I’d advise waiting for roughly 30 minutes. It ought to give a top-tier charger enough time to provide an accurate battery charge level reading. The following step will be completed for you if you purchased a charger that came with a voltage regulator. When the required voltage is reached, this regulator will turn itself off automatically. But until it is fully charged, those who didn’t must check the charge meter hourly. You can disconnect your battery once it has received its full charge capacity.
Any Advice On Upkeep And Care?
A deep-cycle battery charger requires little maintenance.
It all comes down to properly storing it inside your rig and adhering to the manual’s instructions.
I don’t see why this device wouldn’t last a long time and produce good results if you did these two things.
Should Your RV Always Be Plugged Into The Charger?
You may always leave your RV’s battery charger attached, but if you do, you’ll need to keep an eye on the battery to make sure its electrolytes aren’t becoming low.
You won’t need to worry as much if you have a trickle charger because these chargers are made to be used for prolonged, steady charging.
