The Renogy Deep Cycle AGM 12-volt 100 AH Battery is widely accepted as one of, if not the best RV battery for boondocking available today for several reasons from its durability, reliability, to a very rich set of features. Due to its pretty big capacity, the Renogy AGM 12 V 100AH can not only power your RV vehicle, but also other devices and appliances that we might need within the RV during boondocking, like extra lighting, microwave, and other appliances according to your needs.

Also, the Renogy, just like all AGM batteries, wouldn’t need any maintenance, is 100% safe and non-hazardous, and won’t spill. There are also several useful features like how it’s designed for solar energy storage (so you can use any solar device with it), overcharging protection, and others.

Key Features

  • Fast charging technology, the built-in IC can maximize its charging speed.
  • Very efficient, can convert up to 21%-24% of solar power to electrical energy.
  • Bonus canvas case with metal eye holes can protect from rough and dirty conditions.
  • Leak-proof, spill-proof and maintenance-free.
  • Built-in pocket that is zipper-closed, can protect the appliances/devices while charging.

Pros

  • Maintenance-free, 100% sealed so spill-proof and leak-proof.
  • Corrosion-resistant.
  • Solar storage capabilities.
  • Plenty of protection features.

Cons

  • Relatively heavy, and not very easy to install due to its weight.

Verdict

The key highlight of the Renogy Deep Cycle AGM 12-volt 100AH is how it’s very easy to use and maintain. It requires almost zero maintenance since its totally spill-free and leak-free. On the other hand, it is very efficient with decent power storage capabilities, making it one of, if not the best RV battery for boondocking. Since it’s designed for solar power storage, you can easily use solar power to charge this battery, which can be useful during boondocking activities.

A minor drawback of the Renogy AGM 12-V 100AH is that it’s relatively heavy at 66 pounds, but it is very durable with various protection features and virtually maintenance-free.

Buyer’s Guide: How to Choose a Boondocking RV Battery

RV Using Battery While BoondockingTo find the right RV battery for boondocking, there are a few different things you should keep in mind.

Starting Batteries vs House Batteries

It is very important to understand that an RV requires two batteries: a standard starter battery and a deep-cycle “house battery”. 

Starting Battery

The main purpose of a starter battery is to provide the engine a brief but powerful surge to start the vehicle — just like the battery inside of a car. Starting batteries are also sometimes referred to as chassis batteries.

RV House Battery

An RV House battery is used to supply a consistent 12-volts of power to the RV itself, which can then be used to power appliances and devices. For instance, let’s say your RV has a tankless water heater, refrigerator, large electric grill, and a high-tech backup camera system all running at the same time. A significant amount of power is required to keep all of these appliances operating, and a typical auto battery is not capable of providing it. A good RV house battery, however, can easily and efficiently supply all of these items and more with constant power.

RV house batteries are deep cycle batteries that produce less energy than starter batteries, but produce it consistently over a much longer period of time. House batteries are also commonly referred to as coach batteries and motorhome batteries. They usually have a much longer lifespan than a standard starter battery, lasting up to three or four times longer.

A high-quality house battery is essential for boondocking and dry camping. For boondocking, a good rule of thumb is to look for an RV battery with a high amp hour capacity. 

 

Different Types of Deep Cycle Batteries: Material

Generally, there are two different types of deep cycle batteries, which are categorized by the material used to make them:

  • Lead acid. Most rechargeable batteries use valve regulated lead acid technology due to its affordability and the fact that it is relatively reliable.
  • Lithium. Lithium batteries are lighter in weight, more compact, and would generally require less maintenance. However, they are generally more expensive although they have a much longer lifespan.

 

Different Types of Deep Cycle Batteries: Technology

Based on the technology used to produce electric energy, there are three common types of deep-cycle batteries:

  • Flooded Electrolyte. This is the most common technology used in rechargeable batteries. They will require occasional maintenance like checking and refilling the distilled water levels when required. The biggest downside of this technology is corrosion produced at the terminals, which will require regular cleaning from time to time. Generally the most affordable type.
  • Gel Technology. Batteries that use Gel Technology tend to cost more than standard flooded electrolyte batteries, however, they last longer and do not require maintenance. However, they are generally worse at fast charging compared to flooded electrolyte batteries.
  • AGM (Absorbed Glass Mat). AGM batteries tolerate fast charging better than gel batteries, and as with gel batteries, last longer than flooded electrolyte. Often regarded as the best type today.

 

RV Batteries for Boondocking FAQs

Can you use a regular car battery in an RV?

No, you cannot use a car battery in an RV. Automotive (non-RV) batteries are designed to produce surge powers (brief but very high amounts of power) to start the engine. While your RV also requires a true deep cycle battery to provide consistent power. Check out the buyer’s guide section above to learn about the difference between a starter battery and a deep-cycle battery.

What are RV batteries made of?

RV batteries, as well as most other rechargeable batteries, are made with lead-acid technology because it is both effective and affordable. There are some nickel-cadmium (NiCad) RV batteries available, but they are generally more expensive. Newer batteries use lithium-ion technology and other variants using lithium, but currently, they are still significantly more expensive than lead-acid batteries.

Can you store an RV battery in your house?

Yes, virtually all RV batteries are pretty safe to store in your house, but make sure the area is well-ventilated. Don’t store the battery in areas with heat sources like a stove, that might cause your battery to explode. Also, avoid storing your battery in a fully-sealed, air-tight container (this can also cause an explosion).

What is boondocking?

Boondocking is a term used to describe traveling in an RV without the ability to connect to any water, electric, or sewer services. It is also commonly referred to as “dry camping.”

 

Final Thoughts

When it comes to boondocking, choosing a dependable RV battery is absolutely essential.
