They only work when plugged into shore power, when the generator is on, or when your RV outlets work on battery power through an inverter. 110/120-Volt Residential Outletsġ10 or 120-volt outlets supply power to household appliances and TVs. Generally, an RV will have 110-volt and GCFI outlets, while some might have 240-volt outlets, which can run an electric furnace or an electric water heater. You can extend this by conserving electricity, turning lights off, or adding another battery. Under normal circumstances, an RV battery can run for 2-3 days. What Does a Battery Power in Your RV?īatteries in your RV can power the lights, water pump, and small appliances. Batteries in your RV run on DC (direct current). Shore power comes to your RV via a pedestal in your campsite that you connect to your RV with an electric cable. Shore power is an AC (alternating current) power source. What’s the Difference Between Battery Power and Shore Power? The bigger the lead plate and volume of electrolyte in the battery, the more charge it can store.ĭeep cycle batteries, or house batteries, offer a steady current over a period of time. These lead-acid batteries are made up of lead plates, and lead oxide is stored in an electrolyte substance of sulfuric acid and water. 50-amp motor coaches usually have two 12-volt deep cycle batteries. 30-amp motorhomes typically have two 6-volt deep cycle batteries that look like car batteries. RV outlets can also work on generators and batteries when you’re boondocking.ĭirect current outlets are powered by the electricity stored in your coach batteries. RV outlets can be powered by shore power, which is hooked up from the post at your campsite to your RV via an electrical cord. Let’s take a look at how RV outlets work on battery power. Before going down that long and twisty road, you might need some clarification. When you start talking about how RV outlets work on battery power, it can lead to conversations about inverters, converters, solar panels, solar controllers, and generators. Make sure you are using a functional smart converter and don’t let the battery run flat by leaving it for prolonged periods without a charge.Do RV outlets work on battery power? Everything in your RV is fairly seamless or should be when you are attached to shore power. The key takeaway from all of this is to take care of your RV battery to avoid it from overcharging. Most of the time though, it’s something related to the converter. RV batteries aren’t designed to last forever – only about 3 or 4 years – so if it’s an older battery, that might be the cause. There are other instances where an overcharged RV battery is the result of something else, like aging. If you don’t have a smart converter, investing in one could save you the headache of a dead battery from overcharging. The easiest way to prevent this is to use a smart converter and make sure it doesn’t get stuck on bulk or absorption mode. How do you prevent an RV battery from overcharging? In other cases, using a standard converter for too long can overcharge the battery of an RV. Overcharging normally occurs when the smart converter malfunctions and is left on bulk or absorption mode. What that means for your battery is that without proper care when charging, it could quickly drain itself entirely. RVs are almost always using energy, even when they’re parked and idle.
