Hence, this article is going to be a lot helpful and useful for you since you won’t need to waste your time scrolling through varieties of batteries. Before you start checking out the best 6V RV battery options, there are a few important factors related to batteries that you must know about:

  • Battery Capacity: Most battery manufacturers usually provide information about battery capacity in terms of Ah, or say Amp Hours. That said, most of the 6V RV batteries that you will find have around 200-250 Ah battery capacity as it’s what most people believe is the ideal capacity.
  • Type of Battery: Before you finalize a battery option for your RV, make sure to check the battery type. While the traditional lead-acid batteries usually have leakage problems about which most people complain, you should go with AGM batteries instead as they don’t leak and are much more reliable and long-lasting than the traditional ones.
  • Build Quality: Apart from the performance-based features, the build quality of the battery should be a major concern for every customer. Make sure the battery you choose is sealed properly and is made from high-quality materials only. Since you will be installing the battery in the RV, it should be durable and tough enough to absorb the shocks properly.

With these three major factors in mind, you can pretty much easily choose the best 6V battery for your RV. However, there are a few additional factors that you can consider. Thus, if you are a new customer and don’t have much knowledge about RV batteries, we have provided a detailed buying guide later in this article.

Buying Guide for the Best 6V RV Batteries

6V batteries are often used and appreciated for having a long lifespan as compared to 12V batteries and other options. However, if you don’t know much about batteries, picking the right option for your RV might be slightly difficult for you. There are so many battery options available in the market good enough to confuse anyone.

That said, we don’t want anything like that to happen with our readers. Therefore, in this buying guide, you will come to know about all the essential factors related to RV batteries. Thus, make sure to read this buying guide until the end so that you can make your decision wisely and pick the best suitable 6V RV battery from the best options that we have shortlisted from the market.

Type of Battery

Batteries that you might come across in the market can be of various types such as flooded batteries, AGM batteries, Li-ion batteries, Gel batteries and much more.

Out of all these options, the ones that you might require for an RV is either a flooded 6V battery or an AGM battery. Flooded batteries are being used in rigs for a long time and are proven to be quite useful as they work wonderfully and handle overcharging pretty well too. But, the only problem with flooded batteries is that they can leak which could cause several issues.

On the other hand, AGM batteries are just a better version of flooded batteries which come with an absorbed glass mat, so there’s no liquid acid present in these batteries. Hence, there’s no chance of spillage eventually.

That is why AGM batteries are considered to be tougher and long-lasting. Moreover, the self-discharge of AGM batteries is significantly lesser, so you should consider buying AGM batteries over the traditional ones.

Battery Capacity

While buying a battery for your RV, you should definitely check the capacity of the battery before paying for it. For ideal usage, it is advised to use a battery that has at least 200-250 Ah capacity for efficient and long-term usage. In general, flooded batteries and AGM batteries are only able to provide about 50% usable capacity, so it’s highly important that the battery must have a capacity of over 200 Ah.

Size of the Battery

Along with the battery capacity, checking for the overall size, weight, and dimensions of the battery is also quite important. In case your rig has limited storage for the battery, installing a bigger bulky battery would not be possible. That said, you should ensure that your rig has enough space, and choose the battery of the right size that could easily be installed.

Build Quality

As we said earlier, since you are looking for a 6V battery that could be installed in your RV, you will have to choose between flooded lead-acid batteries or AGM batteries. Moreover, the batteries that are installed in vehicles are more prone to damage because you never know what type of terrain you have to go through.

That said, you should choose a battery that is well-constructed and has a sturdy build quality. Moreover, the battery should have proper resistance for both shocks and vibrations too.


Last but not the least, although most 6V batteries usually last for years without facing any damage since they are designed that way. However, you should never trust an unknown brand while picking a battery for your RV. That said, we have only shortlisted batteries that are offered by the top brands in the market since they offer excellent customer support.

In addition, while checking the specification of batteries, you should always check for the warranty information as well. In the case of 6V RV batteries, most brands out there offer at least 12 month long warranties while some brands even offer 18 month or 36 month long warranties too.

FAQs about RV Batteries

1. Should we go for a high-capacity battery?

Ans. That depends on what type of camping you usually do. If you take out your motorhome occasionally for a few days, a small capacity battery will be good enough for you. On the other hand, if your motorhome has appliances installed and you use it for living, having a higher capacity battery is a necessity.

2. Why are AGM batteries better than Wet Cell batteries?

Ans. Wet Cell batteries are also known as flooded batteries since the electrolytes present inside such batteries are surrounded by liquid lead-acid. So there’s always a risk of spillage if any damage happens. In the case of AGM batteries, there’s no liquid inside since the glass mats usually absorb most of it. Moreover, AGM batteries are usually well-sealed and are built tougher, so there’s no risk of spillage, and they last longer.

3. How long do 6V RV Batteries last?

Ans. Although most 6V RV batteries are usually rated to have more than 500 cycles before you might need to replace them with a new one. That said, you can even use a battery for about 2-5 years, but that totally depends on how much you take care of it. Maintaining the water levels, keeping it clean, and even using the battery regularly are some important things that you should take care of.
