In this article, I will answer the question: Does an RV battery charge when plugged in? I will also share everything you need to know about RV batteries.
Let’s begin.
Does an RV Battery Charge When Plugged In?
The short answer to this question is yes. Yes, an RV battery charges when plugged in. In other words, every time you plug an electric hookup into your RV, its battery will be charged.
However, because this is trickle charging, your battery’s electrolytes will be consumed since the battery will quickly be assessed. Therefore, you need to investigate the condition of your battery after plugging in an electrical hookup for a long time.
The right way to charge your RV battery is to use a 3-stage RV battery charger. This will allow better charging and is less likely to harm your battery.
Understanding RV Batteries
RV batteries are deep-cycle lead units that can store electrical power and supply the same power to gadgets and devices at a stable rate to ensure they function usually.
So your RV’s LED lighting, microwave, refrigerator, hot shower, radiator, AC, and other features cannot function with your RV’s battery or battery supply power.
Since RV batteries do not produce their power, they must be charged. If RV batteries are not authorized or remain uncharged for so long, they stop working.
Most RV manufacturers recommend charging RV batteries when 50 to 55% drained. According to experts, RV batteries can last up to ten years if they are consistently charged before draining too much.
As mentioned above, RV batteries are deep-cycle units. They differ from other batteries in that additional batteries supply only energy bursts while delivering stable energy for an extended period.
The batteries that produce power in energy bursts are ideal for machines or gadgets that require a burst of energy to kick off. In contrast, deep-cycle batteries provide stable power, perfect for powering RV kitchen appliances and other features.
How to Maintain RV Batteries
Improper or poor charging of RV batteries destroys them and reduces their lifespan, while proper charging of RV batteries prolongs their lifespan. Below are some things you should do to maintain your RV batteries.
1. Disconnect the Ground Wire When Plugged In
When plugged in, RV batteries continue charging even if fully charged. This usually exhausts the number of electrolytes in the batteries.
To prevent this, experts advise disconnecting the ground wire when camping and plugging in to stop the drainage of RV batteries.
2. Keep Your RV Batteries Fully Charged
RV batteries perform optimally when fully charged or have a reasonable charge. If they frequently function with only 40 percent or less of their capacity set, they do not perform optimally, and their lifespan can be reduced.
So, it would be best to charge them frequently to ensure your RV batteries continue powering your RV for a long time.
3. Maintain The Charge At 45% or More
As mentioned above, RV batteries function optimally with a lot of charge. If you frequently drain your RV batteries below 45%, you will reduce their lifespan.
If you frequently drain your RV batteries to below 20 percent, you will be actively reducing their lifespan, and it could get to a point where they cannot charge to 100% again.
So always keep your RV batteries charged at above 45%. If your RV’s battery has no battery level indicator, you should check its voltage to determine its charge status.
4. Switch Off Your RV Batteries If You Are Long-Term Camping
Suppose you are going to camp somewhere for an extended period. In that case, you should switch off your RV batteries to stop parasitic draining by components such as gas leak detectors, fire detectors, stereos, electric awnings, and so on.
Switching off your RV batteries will prevent drainage and keep them healthy.
5. Monitor the Electrolyte Levels in Your Batteries
The most important thing to do to maintain your RV batteries, besides keeping their charge above 45%, is to monitor their electrolyte levels at least once a month.
You should refill your batteries with distilled water if the levels are low. Doing this will keep them healthy and prevent their damage.
6. Make Sure They Don’t Get Too Hot
Hot temperatures destroy batteries. They reduce their lifespan and can kill them.
Therefore, if you go camping in a hot destination or during hot months, you should act to prevent your RV batteries from getting too hot and refill them with distilled water in case their electrolyte levels go low.
7. Prevent Overcharging
Overcharging can significantly damage your RV batteries. It can also kill your RV batteries. Therefore, to maintain your batteries and prevent them from dying, you should not overcharge them.
You should get one if your RV battery or batteries do not have an indicator. A battery monitoring device will tell you when your battery is full to stop charging.
8. Switch Off Your Batteries When Not Using Them
RV batteries usually come with a disconnecting switch that you can use to switch them off when not using them. This is perfect because electronics, stereos, gas lead detectors, and clocks drain RV batteries slowly, even if they are not on.
Therefore, switching off your camper’s batteries prevents their usage and ensures they last longer.
9. Cut Discharge Level
One of the best ways to protect your RV batteries is to cut their discharge level. Doing this will ensure your battery or batteries do not go below a certain level and affect the power going to your appliances.
10. Prevent Sulfation
Using an RV battery maintainer and conditioner, you should prevent Sulfation and ensure your RV battery or batteries continue working optimally for your camper.
