Specifications

Dimensions 9.5 x 7.3 x 11
Weight 72lb
Amps 225Ah
Terminal posts 8mm (included)

Features

  • Low-maintenance
  • Can fit many applications
  • Many recharging options
  • 8mm terminal
  • Strong amperage
  • Rugged durability

The first battery on our list is the VMAXTANKS 6-volt 225Ah AGM battery. We picked this high performance deep cycle battery because it is designed to work — and work well — no matter where you may end up. This battery is built to give your RV a strong and uninterrupted flow of power, while also allowing you several different options in how to use and charge it. With 6 volts and up to 225 ampere hours you can supply continuous power to your RV for up to 20 hours — and if you choose you can even couple it to another 6V battery to increase your overall voltage to 12.

This battery can operate under extreme conditions, with an operating temperature range that extends from -4 F all the way up to 140 F. This means that, for most situations you find yourself in, you can rely on this battery to work and keep your camping experience optimal. This battery can also recharge under harsh and unforgiving extremes, as well, with a standard AC charger — although solar and wind chargers are also able to get the job done.

One of the best things about this battery is that it is designed to be maintenance-free and long-lasting. As an AGM battery, there is no need to check the specific gravity of this battery or add water — which leaves you more time to play and less time to worry about your battery, which has a float service life span of about ten years or so.

#2 Trojan 6 Volt Battery T-105

Trojan 6 Volt Battery T-105 review

Specifications

Dimensions 7.11 x 10.3 x 11.07
Weight 62lb
Amps 225Ah
Terminal posts 3 types — low profile, high profile and automobile post (all embedded)

Features

  • Multiple terminal types
  • Increased output
  • Strong and reliable power
  • Weighs less
  • High performance
  • Small

The second battery on this list is the Trojan T-105. This popular battery is a more economical deep cycle battery that still manages to deliver all the power you’ll need. Built with Trojan’s patented “T2” technology, this battery delivers an increased output, a longer life than other flooded batteries and high performance. Rated at 6 volts and delivering 225 Ah, you can fully rely on this flooded lead acid battery. And, like other 6 volt batteries, you can even take multiple batteries and sequence them together to provide even more power for a longer span of time.

As mentioned above, this is a flooded battery, which means the plates are fully submerged in an electrolyte solution, which requires regular maintenance — unlike AGM batteries. As long as they are well-maintained, however, these batteries are still able to last for an average of five to seven years (although many T-105s have lasted even longer) and provide strong and reliable power for that whole time.

This is one of the most popular deep cycle batteries on the market, simply because it offers a fair, reliable, economic solution. However, if you’re not looking for a battery that requires a little bit of maintenance, then the T-105 might not be the right battery for you.

Weight 65lb

  • Almost no maintenance
  • Easily charged through a variety of methods
  • Last long
  • Installs easily and can be linked to other battery

The third battery on this list is the NPP NP6-200Ah 6V 200Ah AGM battery. This is another AGM battery, like the VMAXTANKS, which means that it is considered a “dry” battery with very little liquid on the inside. These batteries tend to last a little bit longer than flooded batteries, and are generally easier to take care of since they require very little maintenance overall.

Unlike the VMAXTANKS battery, though, this battery only delivers 200 Ah, which means that you are looking at a downgrade in performance and total output. Depending on how many devices you are looking to run, and your complete power needs, a lesser Ah like this could potentially mean sacrificing some of your comfort down the road (literally) as devices compete for current.

Like other AGM batteries, you can expect a long life of about ten years with the NPP NP6-200Ah, and much of that will be relatively easy, with little or no care put into it. This battery can be easily charged through a variety of methods, including AC charging, solar and wind, so you should never find yourself stranded or in need. It installs easily and can be linked to other batteries to increase output and capacity, which can help alleviate some of the potential issues that come with less amperage.

#4 Crown CR235

Crown CR235 review

Specifications

Dimensions 10.25 × 7.06 × 10.94
Weight 63lb
Amps 235Ah
Terminal posts posts and screws

Features

  • Most powerful battery in this list
  • High-performance
  • Relatively light at only 63lb in weight
  • PROeye indicator

The Crown CR235 is another flooded battery, similar to the Trojan T-105. What sets this one apart, however, is the strong amperage this battery delivers, with a rating of 235 Ah. Depending on your needs and how much current you draw in your RV, this means that this one battery can go pretty far — and even farther when chained to other similar batteries.

Crown boasts that this battery is built with the “thickest lead plates in the industry” which help contribute to a stronger power output and a longer battery life. This battery also comes with both post and screw-type terminals to allow you to connect to your RV and other applications in whatever way is most convenient for your situation.

As a flooded battery, though, this battery does need regular maintenance in the form of adding water and testing the specific gravity of the electrolytes — all things that, if not done properly, can severely impact the performance and life of the Crown CR235. Users who are not willing or able to put that amount of effort into this battery might be better off looking elsewhere. The good news about this is that Crown has tried to make this easy by adding what it calls a “PROeye indicator.” This is basically just a feature that allows you to check the water levels with one quick glance, rather than having to open it up to test.

#5 Lifeline Marine AGM Battery – GPL-4CT

Lifeline Marine AGM Battery review

Specifications

Dimensions 10.28 x 7.06 x 9.92
Weight 66lb
Amps 220Ah
Terminal posts M8 threaded insert

Features

  • Require very little maintenance
  • Full day of use
  • Plenty of recharging options
  • “dry” battery

Our final battery is the Lifeline Marine AGM Battery – GPL-4CT. As the name implies, this is another AGM battery, which is a “dry” battery that requires very little in the way of maintenance or upkeep. This one has a slightly lower Ah rating than the VMAXTANKS, at 220, but this amount of amperage is still able to delivery plenty of power. In fact, this battery can last anywhere from 6 hours at 25 amps all the way to 28 hours at 8 amps. That’s over a full day of use, if you’re not drawing too much out of it!

Lifeline batteries certainly have their share of supporters, and for good reason: this is a brand known for designing and producing high-quality batteries that never let you down, and the GPL-4CT fits right into that history and reputation for craftsmanship. With a life expectancy of at least 10 years, and plenty of recharging options including AC chargers, solar and wind, you can be sure you’ll get plenty of use out of this battery as long as you adhere to proper battery procedures.

All in all, the Lifeline Marine AGM battery is another great battery to consider when trying to decide which choice is best for you and your RV.

BUYER’S GUIDE

When it comes right down to it, all of these batteries provide great options. So, how can you know which one is right for you? There are several things to consider. Deep cycle batteries, such as the ones listed here, are batteries built for long, continuous use. Therefore it’s important to get one with high ratings in features such as amp hours and durability.

Price is another important factor to consider. While it’s true that “you get what you pay for” it’s also true that some items are just priced higher than others for no apparent reason, so it’s important to do your homework and read the specifications and ratings.

Another factor that you should take into account is maintenance. While all batteries require some form of maintenance, including following proper charging and discharging rules and procedures, there are certain types of batteries — AGM, in this case — that are simply easier to use, and create less hassle and worry.

How long do 6v RV batteries last?

6V RV can last 6 or more years. A deep-cycle battery should last longer if it is properly maintained.

CONCLUSION

For all of those reasons, when it comes to buying the right battery, we recommend the VMAXTANKS 6V 225 Ah AGM battery. While this can be a bit pricey, it is certainly worth the money and will give you every penny’s worth.

If you are a little more budget-conscious, the Trojan T-105 is a great second choice.

We hope this little guide has helped you make the right choice. Happy Rving!
