batteries for RV

Vacations are meant to be fun; even more so if you are fortunate enough to own an RV. Don't risk the fun of your RV outing; it’s better to make sure you have the best RV battery on hand to prevent unforeseen complications.

It’s easy to take a fully-charged battery for granted. I’ll never forget when my Dodge Intrepid’s battery ran out of juice during a family vacation in Branson, Missouri. Because running out of electricity can really dampen an otherwise happy outing with unplanned headaches.

In addition to the best RV battery, it’s crucial to have a battery charger and a pair of jumper cables, just in case. If you don’t, it could spoil your vacation. The whole point of recreational vehicles is to enjoy your spare time with loved ones. Without the best RV battery, you're leaving yourself open to the risks and dangers of being stranded on the highway trying to puzzle out how to recharge your vehicle.

Considerations For The Best RV Battery And Longevity

Oxidants, acids, and salts have the innate ability to corrode metal. And battery leads are made of various types of metal. To mitigate the wear and tear on your battery and protect its useful life, it’s imperative to perform regular maintenance with baking soda and a wire brush to clean the terminals.


How RV Batteries Work

Recreational vehicles have different types of batteries. Some recreational vehicles have solar panel arrays, which draw power from sunlight and store power in a battery for electronic components not associated with starting the engine. In addition, RVs have starter batteries, which the alternator recharges, and they supply power to start the engine.

Moreover, SLA (Sealed Lead Acid) batteries use a combination of tin, antimony, calcium, selenium, and sulfuric acid combined with water to create electrolytes that generate current.


Frequently Asked Questions

Most people are aware that batteries act as a reservoir for electricity, but often have many questions regarding their functionality.

1. Why does my RV have a marine battery?

2. Is it imperative to use deep-cycle batteries?

3. Will car batteries work in an RV?

4. How long does the best RV battery last?

5. How many volts must the battery have to work properly in my RV?

The VMAX MR127 is the next alternative for the best RV battery models, and VMAX certainly has a flashier exterior design than other manufacturers. And though it is a 12-volt battery, it differs from the previous models because it has 100-amp-hours, which is significantly more than preceding models.


However, it costs significantly more than all of the other batteries and is an outlier towards the high-priced end of the spectrum.


Also, the manufacturer claims that it uses no silica gels or other contaminants and that this model is an AGM battery. The manufacturer further claims that this model fits any Group 27 battery box and works with trolling motors.

  • Technical and physical specifications can be viewed in the photo gallery (image #2)
  • 100 Amp-Hours at the 10 hour rating. 110 Amp-Hours at the 20 hour rating! 1 year warranty.

The WindyNation SLA Battery doesn’t have a flashy exterior and instead looks like a standard black battery. This contender for the best RV battery, however, has two advantages over the other batteries.


First of all, it is a 100-amp-hour battery, whereas some of the previous batteries were only 35-amp-hours and 75-amp-hours. Secondly, it’s significantly cheaper than the other 100-amp-hour batteries.


The manufacturer designed this model for Solar RV UPS (Uninterpretable Power Supply) and measures it 100-amp-hours at the 10-hour rating. In addition, the manufacturer measures it at 110-amp-hours at the 20-hour rating.


We wished that this model had a longer warranty, though we were pleased to see it at least has a one-year manufacturer warranty.


Unfortunately, a critical customer review claimed that this model only lasted them for six months.


On a more positive note, multiple reviews claimed this was a good-quality battery that worked well with their solar panels.

  • Technical and physical specifications can be viewed in the photo gallery (image #2)
  • 100 Amp-Hours at the 10 hour rating. 110 Amp-Hours at the 20 hour rating! 1 year warranty.

The final contender for the best RV battery model is another VVMAXTANKS product. This model is only a 35-amp-hour battery, which the manufacturer priced even cheaper than most of its other products.


One thing we liked about this model is that the manufacturer had its customers in mind when designing its exterior. Unlike most other battery models, this one has a convenient detachable metal handle on top. Batteries are incredibly heavy, and this foresight by the manufacturer makes it significantly easier to move and install.

PROS

  • Great carrying handle
  • Very inexpensive
  • Maintenance-free

CONS

  • Only a 35-amp-hour battery
