How To Choose The Best 6-Volt RV Battery?

Battery Material Types

Batteries are manufactured using different types of materials. Each of these materials has its significance. Batteries are usually made from either lithium, AGM, or they are of Lead-acid.

Lithium batteries are more expensive than the others on the list. But, they are cheaper and last longer than other material batteries. But, there is a drawback in lithium batteries. In cold temperatures, they cannot perform very well.

The next in line is the Absorbed Glass Mat batteries. They are more commonly known as AGM batteries. These batteries use a fiberglass mat that absorbs Sulphuric acid. They are maintenance-free lead-acid batteries. Compared to lithium batteries, they can very well handle cold temperatures. They have a slightly shorter lifespan than lithium batteries.

The Lead-acid batteries are the cheapest ones on the list. But they require maintenance every few months. Their cells need to be topped up with distilled water every couple of months. You can recharge a lead-acid battery, but its average lifespan is shorter than that of AGM or Lithium batteries.

Battery Sizes

The size of a battery is as important to consider as its material type. Size is important to consider because most RVs have limited areas where you can fit a specific size battery.

But, when buying an RV battery, you should consider both sizes of it. It’s capacity size, how much AH it can deliver, or what its RC is. And the physical size of the battery, if it can fit in your RV or not.

A bigger battery will provide more power and benefits compared to a smaller one. But, for an RV, you’d have to go for smaller batteries. In these batteries, look for a quality one that can provide more AH and RC. And make sure the battery you select can fit in your RV.

To get an idea of the size of the battery for your RV, you can check the RV’s original battery. But if you are not satisfied with its performance or that a bigger battery will last longer. We’d recommend checking the space available before making such decisions.

Discharge Depth

Depth discharge is one of the most important factors in batteries. To give you an idea of how much power gets discharged by battery, the brands provide a value in percentage. The higher the percentage, the lower the capacity.

When you’re planning on buying batteries, especially lead-acid batteries. It is better to note their discharge depth and life cycle before buying one. If they have a model with deeper individual cycles, it will have a shorter lifespan.

Operating Temperature Range

If you use RV regularly for travels, then you should prepare yourself for extreme temperatures. Most batteries function properly in slightly cold or warm weather.

But when it comes to severe weather, their functionality can decrease. You should make sure the battery you’re getting won’t leave you stranded in a 0° environment.

If you have a Lead-acid battery, its life will decrease by half over every 10°F increase in temperature. So, using a lead-acid battery during summer trips won’t be the best idea.

That’s why you should know how your battery will behave at a said temperature. For example, if you plan to travel in cold weather, getting a lithium battery won’t do the trick. Their performance significantly drops in cold weather.

That’s why manufacturers put this information on their product descriptions. So, check it out before getting a battery for your RV.

Construction Quality

When you’re buying a new RV 6v battery, we’d recommend checking its brand name before getting it. If a reputable brand makes it, you can be assured that it will be made using premium quality materials. It will also ensure that the battery will have a longer lifespan than other batteries in this range.

While going on bumpy trains on your vacation trip, you’d want to use a reliable option. And that it has a sturdy construction so that it can withstand all kinds of bumps. If you are spending money on a battery, then it should be strong built too.

The battery should be capable of facing shocks and vibrations. If it cannot, you’d find yourself spending extra money on its repairs while on the trip.


How Does A 6v RV Battery Work?

A battery has cells with chemicals. Each of these cells in a battery can have 2-volts. Between these cells, the chemicals transfer ions back and forth. This creates electricity. Inside a 6v RV battery, there are three cells, each with a capacity of 2-volts.

How Many Years Do 6 Volt RV Batteries Last?

Generally, a 6v RV battery can last up to 8 years. But, if they are from a good quality brand. They can last up to 10 years. To ensure their longevity, you should properly maintain them.

Are 6 Volt RV Batteries Better Than 12 Volts?

Yes, in a 6v RV battery, the plates are thicker, and they have more space per cell. With the 6v RV batteries, you have the flexibility to place them wherever you want. Because they are smaller compared to 12v batteries.

Does A 6 Volt RV Battery Charge Driving?

Yes, the 6 volt RV battery charges while driving because of a special charger in the vehicles. But, you cannot expect it to hold enough charge while going to last a long time.

What is the best 6 volt deep cycle battery?

We’d recommend getting the VMAXTANKS 6V 225Ah AGM battery. This battery is an all-rounder battery. It uses AGM technology to store as much charge as it can.

It is a maintenance-free model where you won’t have to check it every week. And the lead-tin alloys used in this battery enable it to have a long lifespan. Overall, this is the perfect battery for you if you want to camp without any hindrance.
