If you want your appliances to run after the main engine of your RV has been shut down for the night while you’re traveling with your family, you’ll need to have a strong RV house battery.

But if you’re like the majority of RV owners, you’re still working on understanding how RV electrical systems function.

In this post, we’ll go over what to look for when buying an RV house battery and why choosing wisely will significantly affect how much you enjoy using your RV while traveling.

How to Select a House Battery for an RV

Deep cycle batteries, AGM batteries, lithium batteries, and compact vehicle batteries are the four different kinds of RV batteries.

The benefits and drawbacks of each kind for usage in an RV vary.

Deep cycle batteries will be the best option for the majority of individuals.

Deep cycle batteries may be used in RVs, however there are several versions available.

The three most crucial characteristics of RV house batteries—the maximum discharge rate, the self-discharge rate, and the operating temperature range—must be taken into consideration in order to distinguish between deep cycle batteries and determine which is the best choice for your family’s RV needs.

#1. Maximum Discharge Rate and Capacity

Volts, which are denoted as V in product specifications, are the unit used to measure a battery’s maximum discharge rate.

The unit of measurement for battery capacity is ampere-hours, or simply Ah.

In other words, a battery’s maximum capacity increases with the number of advertised ampere-hours.

The number of appliances you may use simultaneously depends on the battery’s maximum discharge rate, which is crucial.

As a result, a house battery for an RV that advertises a maximum discharge rate of 12V may handle twice as much demand as a 6V battery.

Most RV house batteries increase the battery’s fundamental voltage by up to 10 times so that it can power 120V equipment.

In practice, 6V may be the difference between having to limit the use of several appliances at once and being able to use a toaster oven and an electric kettle simultaneously.

On the other hand, not everyone will need an RV house battery that can power many appliances at once.

You may definitely get by with a lower maximum discharge rate if you want to use your RV only by yourself.

There is never a circumstance when a lesser battery capacity for an RV house battery is beneficial.

#2. Rate of Self-Discharge

The self-discharge rate of a battery, which should not be confused with the maximum discharge rate, measures how quickly a battery uses up its energy while nothing is pulling power.

The chemistry of a battery affects the self-discharge rate of the battery.

Lithium batteries, when used as RV house batteries, have the lowest self-discharge rates and take the longest to completely drain.

Since your RV won’t be using your battery for the great majority of the time, the self-discharge rate is crucial.

When you do need to use the battery to power your appliances, you want the battery to have enough power to do so.

When your RV hasn’t been used for a while, batteries with greater self-discharge rates are more likely to be dead.

Batteries with low self-discharge rates, on the other hand, will consistently have enough charge to run your appliances when you need it.

#3. Range of Operation’s Temperatures

It may seem strange to pay attention to the operating temperature range of your RV house batteries, but it’s an important component to comprehend.

Batteries self-discharge quite quickly when they are heated, but they do so somewhat even when they are not being used to power equipment.

As a result, if you want to leave your RV in the hot summer heat, you should anticipate that an RV house battery with a smaller operational temperature range would self-discharge more quickly.

In some ways, the contrary is also true.

Batteries cannot self-discharge in colder environments, but if they are warmed up too rapidly from freezing conditions, they might suffer hairline cracks in the battery shell.

Finding an RV house battery with an operating temperature range that corresponds to how you will use and store your RV is essential if you own an RV.

You don’t absolutely need an RV battery that is rated to work at low temperatures if you want to leave your RV outside in the bitter cold throughout the winter.

It’s time to research our top three choices for the best RV house batteries now that you know what to look for when you’re searching for one.

Optimal RV House Battery

#1. Weize 12V 100AH Deep Cycle AGM SLA VRLA Battery

The Weize has a 100 Ah capacity, which is more than sufficient for everyday uses.

The Weize’s output is the same; at 12V, it is enough for at least one large appliance.

When utilizing the Weize battery in the cold, use caution.

Although the battery’s self-discharge protection is certified to survive a typical range of temperatures, it isn’t as robust as you may desire.
