Understanding RV House Batteries
RV house batteries, also known as RV deep cycle batteries or “leisure batteries,” are responsible for supplying power to the living area of your RV, powering lights, water pumps, and other appliances.
Depending on your RV battery setup, you may have one or more batteries connected in parallel or series, to provide power throughout your RV. This is commonly referred to as your “battery bank,” as it acts similar to a bank in which you can either deposit or withdraw energy throughout the day.
RV house batteries must be deep cycle batteries, meaning that they are designed to experience a deep depth of discharge often between 50-100% of the battery capacity.
An RV deep cycle battery will discharge and recharge many times over its lifecycle and it is important to understand the limitations on how much power you can discharge as well as the variety of recharging methods available to ensure proper battery health and safety.
To guarantee the smooth operation and longevity of these batteries, maintenance and monitoring are required. Recognizing the significance of house batteries in an RV is key since they power the appliances and devices that contribute to a comfortable and enjoyable camping experience.
The Role of House Batteries
House batteries provide power to various components within the living area of an RV, such as interior lights, water pumps, vent fans, and other devices. Selecting the ideal RV battery that fits your power needs and preferences is crucial for optimal performance.
Key specifications to consider when assessing an RV battery include group size, type of battery and battery capacity (in amp-hours) and depth of discharge. Other features, such as size, weight, durability, mounting positions and expected lifespan should also be considered when selecting the best RV battery.
A standard starting battery, like those found in traditional vehicles, is not capable of providing prolonged power over an extended duration. Car batteries such as these are typically a form of flooded lead acid battery that is designed specifically to deliver large amounts of power over a short timespan and they are not intended to discharge lower than a certain amount before being recharged.
This is where deep cycle RV batteries come into play, as they are specifically designed to provide continuous power for your RV’s needs.
Familiarizing yourself with the specifications and disparities between a starting battery and a deep cycle battery is vital for maintaining the power and functionality of your RV’s living area during your travels.
How House Batteries Differ from Chassis Batteries
In a driveable RV, there are two main types of batteries: chassis (or vehicle) and house batteries. Chassis batteries are designed for starting the engine and supplying energy to auxiliary systems, similar to car batteries.
On the other hand, house batteries are intended for continuous power delivery rather than one big burst of energy and as deep cycle batteries, they are designed to be cycled between 50-100% of their capacity.

Additionally, the vehicle’s alternator ensures that the chassis battery, typically a lead-acid battery, remains fully charged during operation. On the other hand, you can recharge your RV batteries by a variety of methods including shore power, a solar system, generator or the alternator.
Selecting the Right RV House Battery
The selection of the right RV house battery takes into account factors such as capacity needs and the benefits of various battery types.
For example, lithium batteries are lightweight, durable, require little maintenance, can have a deep depth of discharge and have several thousand recharge cycles.
In contrast, flooded lead-acid batteries and lead acid batteries such as AGM and gel cell batteries are more affordable but require regular maintenance, may require venting and are much heavier and bulkier than their lithium ion counterparts.
You must also take into account the capacity needs of your RV house battery, particularly if you intend to use several batteries in your system. Ensuring that your battery has the capacity to meet your power requirements will prevent unexpected power outages and keep your RV’s appliances functioning optimally.

Determining the capacity needed for your RV house battery involves assessing your power usage and desired runtime. While the capacity of an RV house battery can vary, a typical deep-cycle RV battery is rated at approximately 100 amp-hours. How much of this capacity you can use depends on the kind of battery that you have. And it is also possible to add multiple batteries together in parallel to multiply the total battery bank capacity.
However, before you purchase your next deep cycle battery, it is important to estimate the required capacity for your specific needs. To do this, you will need to consider your daily power consumption and the runtime you desire when not connected to shore power.
For example, if you have a residential refrigerator in your RV that consumes 130Ah per day, it’s suggested to have a minimum of 200 amp-hours of usable battery capacity. This estimation ensures that a good RV battery can provide sufficient power for the refrigerator and other appliances during your camping adventures.
This is a great example of a calculator you can use to estimate the amount of power you will use on a given day and the type and amount of deep cycle battery or batteries you may need to purchase.
Battery Types and Their Advantages
Comparison of the pros and cons of various battery types like flooded lead-acid, AGM, and lithium batteries is critical when choosing an RV house battery. Flooded lead-acid batteries are cost-effective, but require regular maintenance, may emit dangerous gases, are generally much heavier and can only be discharged to 50% to prevent damage to the battery.
On the other hand, AGM batteries are maintenance-free, can endure deeper discharges (up to 60%), and are more expensive than flooded lead-acid batteries.
Lithium batteries, including lithium ion batteries, offer numerous advantages, such as a longer lifespan, lighter weight, maintenance free and the ability to manage deeper discharges (up to 100% of the battery without causing damage).
But they do come with a higher price tag than other battery types so you must have an understanding of value when it comes to upgrading to lithium RV batteries.
