As an RV owner and traveler, I want to make sure that we’ll enjoy our trips without hassle. Some of the problems we might face are a loss of water, flat tires, or loss of power.
So far, the worst thing that happened was that we couldn’t use the air conditioner because we were running low and we had no way to plug into a power source.
One time we went dry camping, and we were confident that we’ll have enough power. You see, we got the best RV generator, and we’ve had it for years now. Whenever we go somewhere, we make sure that our RV generator is fully charged so we can use it for emergency power supply.
RV living is a bit complicated but worthwhile. You just need to be responsible enough and make sure everything is in order before you travel.
In most cases, you can always go to a campground and plug into their power source. However, there are some instances that campgrounds are full, so it’s better to be well-prepared.
In this article, I’d like to share with you some tips especially on how to charge the RV generator even while driving. I’ll also share with you other advice on how you can charge your RV battery.
Before charging up your RV battery, it is best to take some safety precautions by inspecting the battery and the electrical system. These safety practices ensure that you will not be harmed or your RV won’t be damaged. We shall also include battery inspection before charging to ensure added security.
Make sure that your generator is fully charged or plug it into an AC outlet.
Your RV should be turned off and the emergency brake engaged to avoid accidents.
Find out where the RV battery or batteries are located.
Inspect the batteries for signs of bulging, cracks, and corrosion. If your battery terminals are dirty, proceed to the next step. Otherwise, skip to Step 8 .
Before cleaning the RV battery, use a wrench to remove the cables. Remove the black cable (negative) first before the red (positive) one.
Create a mixture of baking soda and water to create a paste.
Using a toothbrush, apply the paste to the battery terminals. Get a wire brush and remove the corrosions.
After all the grime has been removed, wipe it off with a clean rag and make sure the terminals are completely dry.
Apply petroleum jelly or a battery rust protector to the terminals.
Check the electrolyte levels and pour distilled water up to the fill point if the fluids are low.
Reconnect the RV battery by connecting the red (positive) cable first then the black (negative) one. Using a wrench, make sure they are securely fastened.
Unplug all electrical appliances to maximize charging. Turn off all lights as well.
If you can plug the generator into a 120V AC outlet, make sure it is plugged in. Otherwise, your generator should be fully charged.
Keep in mind that if you are using a portable generator with a 12V C output, charging will be very slow and may not fully charge your RV battery.
The charging time also depends on the weather. If it is below 40 degrees, you may not get the full capacity.
Plug your RV plug into the generator.
It may take up to 2 hours for the battery to full charge if it is not depleted, provided that the generator is plugged into an AC outlet. If your RV battery has dropped below 20%, it will take longer.
Make sure you don’t let your battery get depleted. Keeping the battery charged also extends its lifespan.
After charging your RV battery with a portable generator, manage the use of your electrical appliances until you get to a campground.
Plug the generator as soon as you can for future use.
In case you don’t have a generator, there are still other ways to charge the RV battery. In fact, your alternator charges the RV battery. You may also want to read up on how to charge the RV battery while driving.
RV batteries are different from car batteries. The batteries in the RV couch are not connected to the engine’s alternator which charges a car’s battery when driving.
Here are other options to charge the RV battery:
This method is the most efficient, yet expensive.
You need to purchase and install the solar panels on the roof of your RV.
The size of the solar panels depends on the amount of electricity you consume.
The solar panels are connected to the battery and inverter or charging unit to ensure continuous power source.
You also need to adjust the panels, so they face the sun.
ou can charge deep-cycle batteries for your RV coach using a converter.
A converter, as the name suggests, converts 120V AC power into 12V DC.
However, this device is not an efficient charger. It can only provide an average of 40 amps, and charge your batteries at 3 to 5 amps.
Therefore, it will take you a long time to charge a depleted battery.
You can also purchase a separate battery charger specifically for your RV battery.
The RV battery charger is a portable device that has positive and negative clamps that you should directly connect to the battery.
To use this device, you need to disconnect the RV battery following step 5 above.
These portable battery chargers come with red and black jumper cables like those used to jumpstart a car’s battery. Connect the red clamps to the battery terminal, and the black clamp to a metal ground then switch on the charger.
Make sure that you completely charge the RV battery. An indicator light turns on when done.
After that, shut down the charger and remove the connections starting from the black clamp. Replace the battery connections following step 8 above.
Apart from the safety tips mentioned above, here are a few details to help you maintain the lifespan of your RV battery and your electrical appliances.
Your RV not only has one battery but two or more. The battery for the engine is different from the batteries that provide power to the coach.
To ensure that you’ll have a hassle-free RV living, be responsible enough to maintain the RV batteries. You may also need to purchase additional power sources such as solar panels, generators, chargers, or converters to power up your RV.
In instances wherein you need to plug into a campground, don’t be complacent and just plug into it. Practice safety by checking the voltage and making sure it is stable. However, don’t always rely on campgrounds because there may be many people connected and you won’t get the desired energy.
