How Long Will An Rv Fridge Run On Battery? Read These Useful Facts!

Are you wondering how long will an RV fridge run on battery? Stop wondering and start reading this article. Using artillery, a domestic RV fridge would last around twelve hours. If the RV fridge is built up with it or utilizes propane, it will run off the battery.

The absorption fridge can only operate for approximately three hours on batteries, but this will survive for days if you use propane. The battery capacity of an RV fridge will be affected by whether you use it alone, with an additional source of power, including propane.

how long will an RV fridge run on battery

A domestic fridge for RVs that consumes approximately 150 watts would demand around twelve amps per 60 minutes from a mere 12-volt battery. So, under such circumstances, the 12-volt battery delivering roughly 100 amp-hours could power an RV fridge for about 4-5 hrs. This is just an overview, so keep reading and learn more.

 

Basics Of RV Fridge

RV fridges were inexpensive and portable, allowing you to save cash on food and drinks while on the road. Home refrigerators get a compressor or other mechanical components; however, an RV fridge does not have mechanical parts or a compressor. They’ve been built specifically for road journeys. Absorption refrigerators are another name for them. They employ a variety of power sources, including batteries, inverters, and propane. The refrigerator is kept chilly by condensing or evaporating a liquid component known as a refrigerant.

 

Lifespan Of Rv Fridge That Runs On Battery

So, how long will an RV fridge run on battery? Whereas the mean lifespan of a home fridge on a battery is 12 hours, this timescale could be lowered or extended depending on various circumstances. You can compute the precise number of hours the refrigerator will operate based on the RV’s sort of battery and its battery ratings.

Most RVs have just one 12volt battery, while some have twin 6volt batteries. Assume you get a 12-volt battery with a 100 amp hour rating. The battery can deliver five amps every hr for twenty hours until being entirely depleted. However, if you connect 240-watt inverters into this battery, it will survive for a quarter of the time it usually does, approximately five hours. 

To obtain the figures, divide its watts by the volts to generate a set of amps required each hour, which will be 240W/12V = 20A because the need will be four times that of the battery. Let’s take a much more realistic comparison: imagine you have a household fridge that uses roughly 150 watts of power and is powered by a solitary 12-volt battery.

This fridge would indeed drain the battery at roughly 12 amps per hour. Its battery would be able to run the refrigerator for approximately five hours in this case. While this may appear to be a short period, keep in mind that variables such as adding different numbers and batteries and having a tiny refrigerator will all contribute to lengthening the time frame. A small refrigerator that uses only 70 watts may run for more than thirty hours. There are a few guidelines in addition to extending the life of the batteries.

Upgrade the batteries if possible. Ensure to recharge them at least once a day. You can purchase many batteries or a small number of high-quality batteries. Also, make sure the charge does not drop below 20%. High-charge batteries, which can be highly utilized at times, could also be used. If you want to use the batteries for a home fridge, you may also add solar panels. It could be utilized in areas with higher sunshine. 

Solar panels with a 100-watt capacity are available. The batteries would last longer than other types of this. By exposing the solar panels to daylight for five hours, you may gain Thirty hours of electricity.

 

Using A Battery To Power An RV Fridge When Traveling

In essence, because an RV’s alternator is constantly charging the battery, traveling is among the best times to operate the fridge and other equipment on the battery. Its alternator seems to be the built-in generator in an RV’s motor, and if you’re traveling in a pull-behind motorhome, your battery in the tow truck will supply the fridge through its alternator. 

Some people would keep a regular refrigerator in the coldest setting for a couple of nights before departing on a long drive. The electricity is turned off on the day of the road trip, and the fridge is carried on the road. However, this would not keep the food healthy for an extended period. Home refrigerators are cumbersome to transport and ruin meals within a few hours. Fridges in RVs were usually the best option. The advantages of utilizing an RV fridge are here. Because they are relatively bulky, RV fridges save room.

Because the components of RV fridges aren’t mobile, they’re less likely to need service. Fridges in RVs work with a variety of sources of power. Such fridges automatically change between several energy sources to keep the food nutritious and excellent. These refrigerators are more robust since they can withstand severe temps, shocks, and disturbances. You may also be interested to know about RV fridge not getting cold.

 

It’s A Wrap!

We are happy to know that you have learned how long will an RV fridge run on battery. The RV fridge only runs twelve hours a day on battery, depending upon your battery wattage.
