How Long Will Rv Fridge Run On Propane? An RV fridge with the 20-pound. propane tank to last for up to 280 hours and just 11 days.

Tips: Take a look at our free calculator for the use of propane in our well-known guide on What is the longest time propane can last within an RV? to quickly calculate the use of propane by all appliances within your set-up.

The 20-pound tank is most often used with RV refrigerators. It’s the size that allows for the longest run time and it’s also a very popular size for recreational vehicles.

Keep in mind that an RV fridge will run on propane when plugged into an electrical outlet, but it will use more power than if it were running on battery power alone.

When figuring out how long your RV fridge will run on propane, it’s important to keep in mind that all appliances within your set-up play a role in calculating total usage.

Our free calculator can help you determine exactly how much propane you’ll need based on the type and size of each appliance being used.

Why do people have batteries in the fridge?

A few people swear by keeping their batteries in refrigerators to prolong the life of the battery as well as keep them in good condition (apologies for the obvious food storage joke).

But is there any truth to this method? Let’s break it down.

Batteries contain a number of chemicals that work together to create an electric current. These chemicals are affected by temperature changes, so when you put a battery in the fridge, you’re essentially slowing down the chemical reaction inside the battery.

This means that your battery will discharge more slowly and last longer than if it were stored at room temperature.

Of course, there are some caveats to this method.

For one, you have to make sure that your batteries are sealed tight so that moisture doesn’t get into them and ruin them (this is why most people recommend putting them in a zip-top bag before putting them in the fridge).

Also, extreme cold can actually damage batteries, so you don’t want to store them in the freezer.

All things considered, storing batteries in the fridge is a pretty low-risk way to prolong their life, so if you’re looking for a way to make your batteries last just a little bit longer, this is one method you can try.

Just be sure to seal them up tightly and keep them out of the freezer!

Does RV fridge need battery to run on propane?

While propane refrigeration doesn’t require electricity but you’ll still require at minimum 10.5 V battery to start it up.

This boost in energy is required to allow gas to flow through the base and then ignite the ignitor otherwise, your fridge won’t function.

You’ll know if the battery is too low because the ignitor will just click.

If you’re using a generator to power your RV, this shouldn’t be an issue as most generators provide more than enough power to start up the fridge.

However, if you’re boondocking it’s always good to have a backup plan and extra batteries on hand.

Does a fridge need battery?

The refrigerator will not function using propane if the battery levels aren’t sufficient.

The fridge uses batteries to power the control board as well as for ignition. The batteries must be fairly low.

The refrigerator does not consume a lot of power from propane, however it requires the power source.

If the batteries are too low, the fridge will not be able to function on propane.

It is recommended that you have a minimum of two batteries for your RV.

You can use one battery for the engine and one battery for the appliances.

If you don’t have enough power, your fridge will not work properly.

It is important to maintain your batteries so they don’t run out of juice while you’re on vacation.

If you’re planning on being away from home for an extended period of time, it’s a good idea to invest in a generator.

This will ensure that you have enough power to run all of your appliances, including your refrigerator.

How long will a 20 lb propane tank run a refrigerator?

If you’re using a typical 20lb propane tank you can anticipate it to last about 11-days (non-stop) before you need to refill or replace it.

For a tank of 30 lbs, just increase it by 50%. That means it’s going to last 17.7 days without interruption.

How long will my tank last if I’m not using it all the time?

It really depends on how much you use your fridge. If you open and close it often, then your propane will run out faster. If you have a larger fridge, it will also use more propane.

The key is to keep an eye on the gauge so you know when it’s getting low.

What are some ways to make my propane tank last longer?

There are a few things you can do:

  • Keep your fridge at a moderate temperature. The colder you keep it, the more propane it will use.
  • Reduce the amount of times you open and close the door. Every time you open it, cool air escapes and warm air enters, making the fridge work harder.
  • Make sure the seals on your fridge door are tight. A loose seal will also let cold air escape, making the fridge work harder.
  • Defrost your freezer regularly. A build-up of ice will make your fridge run less efficiently.

How much propane does a RV refrigerator use?

In general, a 10 to 12 cubic feet RV refrigerator will consume about 1.5 tons of propane every day.

If you have a larger fridge, it will use more propane. If your usage is lower, it will still consume about the same amount of propane.

The good news is that most RVs have auxiliary power outlets that can be used to run the fridge while you are driving down the road.

This way, you don’t have to worry about running out of propane while you are on vacation.

One thing to keep in mind is that RV refrigerators are not as efficient as home ones. They use more electricity and gas to cool down and they don’t always maintain a consistent temperature.

How long will refrigerator battery last?

It is generally believed that a 12V-50Ah batteries will power a 2 cubic feet 12V refrigerator for 35-50 hours before it’s depleted completely. A 10 cubic foot RV refrigerator could be run by this same type of battery 10-15 hours.

A lead-acid battery will discharge more quickly in hot weather, so you may need to size your batteries accordingly if you live in a warmer climate. If you have a deep cycle battery, it will last longer than an automobile battery because it is designed for deep, continuous discharge and recharge cycles.

You can extend the life of your refrigerator battery by doing a few things:

  • Keep it charged: A lead-acid battery will discharge more quickly if it’s not kept topped off. Lead acid batteries should be kept between 60%-75% capacity to prolong their lifespan.
  • Avoid excessive heat: Batteries stored in hot environments will age more quickly and have shorter lifespans.

How much battery does a propane fridge use?

The fridge can generally consume about a gallon propane in five days and will use around 20 amps of battery per day.

So, for a long weekend camping trip you may need to take along about four gallons of propane and 80 amps of battery power.

If you are using a solar panel to recharge your batteries, make sure it is sized correctly.

A 100-watt solar panel will only recharge the batteries at 20 amps per day, so you would need a 500 watt (or larger) solar panel system to fully recharge the batteries each day.

If you have questions about how much battery or propane your fridge will use, please consult an expert before making your purchase.

With some simple math and a little planning, you can ensure that your fridge will run smoothly and efficiently on your next camping trip!

Does a refrigerator need a battery?

In simple terms: No. Although colder environments can prolong the battery’s life, refrigerators and freezers aren’t safe places to store batteries in. The humid conditions can lead to condensing on batteries.

This can result in rust or damages.

It can also cause the battery to leak, which can create a mess and possibly be dangerous.

If you’re looking for an eco-friendly way to power your refrigerator, consider using solar panels.

Solar panels are a great way to reduce your reliance on fossil fuels and they’re becoming more affordable as technology improves.

There are a few different options available, so do your research to find the best fit for your needs.

What size battery do I need for a fridge?

To power a refrigerator with batteries for 24 hours, you’d require anything from 50Ah to 300Ah (Amp-hours) of capacity for your battery. 50 Ah is for a small 12-volt refrigerator/freezer (1.6-2.5 Cu. feet.) and 300 Ah is for a large-sized fridge (18-22 Cu. ft.).

If you want to know the average fridge power consumption, a good rule of thumb is that it will use around 30 amp-hours per day. But this number can vary greatly depending on factors like size, insulation quality, and ambient temperature.

Now that you have an idea of what size battery you need, the next step is choosing the right type of battery for your needs. There are three main types of batteries used for off-grid applications: lead acid (wet cell, gel cell, and AGM), lithium ion, and saltwater. Lead acid batteries are the most common type used in RVs and boats because they’re more affordable than lithium ion batteries.


When it comes to RVs, many people are curious about how long the fridge will run on propane.

The answer to this question really depends on a few factors, such as the size of your fridge and the amount of propane in your tank.

Typically, an RV fridge will run for around two days on a full tank of propane.

However, if you’re using an icebox or cooler instead of a refrigerator, it’s likely that your food will only stay cold for 12-24 hours.
