How Do RV Converters Work?

Your RV converter transfers your AC battery power into DC power that you can use on appliances throughout your RV. All appliances rely on 12 Volt DC power; you cannot use AC power to run these devices. If you don’t have a converter, there’s no way to run heavy-duty appliances in your RV unless you have a generator.

You’ll need an RV converter to run your camper’s refrigerator, microwave, and other daily necessities.

You’ll need to identify the cause of your converter issues before looking through our troubleshooting methods.

Common Causes of RV Converters Draining Batteries

If you notice significant battery drainage after plugging in your RV converter, there’s something wrong with your battery or device. It’s abnormal for battery converters to drain your battery enough for you to notice after plugging in the device. We will go into more detail about these common causes below.

1. Poor Battery Maintenance

Your RV battery requires frequent maintenance to ensure everything runs correctly. If you don’t maintain your battery regularly, you’ll have difficulty operating your devices. Many people don’t realize that they need to maintain their batteries to keep them in working order and put all the blame on the converter instead of the battery.

2. Wiring Problems

Another reason your RV converter can drain your battery is that there’s a wiring issue throughout your device. If you don’t have wires hooked up properly, it can cause unnecessary battery drainage in your RV. This situation can also happen when your wires don’t work correctly and don’t give off the right electrical current,

Using an electrical meter to test each wire, you can check for any wiring problems. If you notice any wires have been damaged or don’t work how they’re supposed to, you should replace them to avoid further battery damage.

Sometimes you don’t need a meter to test the wires. For example, if you notice a damaged wire just by looking at it, you should get a replacement. You should replace any wires that have fraying or unusual bends.

3. RV Battery Maintenance

You need to maintain your RV batteries if you don’t want to worry about them draining while driving. Your RV power converter is not usually the reason. Your battery experiences unnecessary drainage. Your battery is supposed to have no issue working with your converter to supply electricity to your appliances.

For more information about RV battery maintenance, follow our guidelines below. We will detail the most important maintenance methods whenever you purchase an RV.

Keep an Eye on Your Battery Level

The main thing you need to worry about when traveling is keeping an eye on your RV battery level. Depending on your RV model, you can check your battery level by looking at your dashboard. This will give you a live reading of your battery life so that you don’t have to worry about discharging your battery too much while driving.

If you notice that your battery falls below 50% of the capacity, you need to charge it back up. If you’re a battery frequently, it falls under 50%. You may need to replace it entirely. Batteries aren’t supposed to last forever; you must replace them once every five years.

Be Mindful of The Weather

Using your RV during notably hot or cold weather can impact your battery life. For example, if you’re driving through excessive heat, you need to pay more attention to your battery life than during comfortable weather. You also need to pay more attention to your battery life when traveling throughout the winter.

Always pay attention to weather conditions while you travel to ensure that your RV remains in great condition. If your RV converter keeps draining your battery, you could be suffering from environmental problems related to your battery life.

Always Keep 10.5 Volts Available

If you drop below 10.5 volts on your RV battery, you’ll encounter many problems. For example, your battery could stop working when you drop below this voltage. Be mindful of your battery output whenever using a converter to ensure that you don’t drain your battery life too much.

However, it’s perfectly fine to exceed 10.5 volts if possible. You need to worry about dropping below this voltage because that’s when you’ll encounter battery problems. Battery maintenance is crucial to RV ownership and can prevent you from getting stranded while traveling.

Execute Caution While Storing RV Battery

People often encounter battery problems when they store their RVs. It’s easy to lock your RV up and forget about it during the off-season. However, if you don’t touch your battery for too long, you might not be able to power up your RV again without replacing this part.

You should turn your RV on and take it for a spin around the neighborhood once every 90 days to ensure that the battery doesn’t die. If you leave your RV alone for too long, you will drain your battery and be unable to start the vehicle.
