The Top 5 RV Batteries Reviewed

RV battery reviewsThere’s no RV without the RV battery. It’s an essential part of the electrical system, providing the power that keeps it running. The engine’s kept running by gasoline but without a battery, you can’t start the car alone, nor can you operate the lights, AC, stereo or any other system that doesn’t run on gasoline.

RVs tend to require more electric power than the average vehicle because they also have outlets that you can plug all kinds of appliances and devices into. For that reason, an RV battery needs to be able to provide more power in the long-run than the average car battery. Adding a solar kit can help meet your electrical needs, but that doesn’t alleviate the need for a high-quality power plant under the hood.

For those of you in a hurry, our choice for the Best RV Battery is the Optima Batteries 8016-103 D34M.

Best RV Batteries

While there are dozens and dozens of different batteries you can choose for your RV, not all of them are created equal. We looked over the specs of the top choices on the market, and also combed through user comments and reviews. From that, we came up with this list of the best RV batteries on the market:

1. Optima Batteries 8016-103 D34M

Optima Batteries 8016-103 D34M Review

The Optima Batteries 8016-103 D34M

The most expensive battery we will be looking at, this is primarily designed as a marine battery, but it works just as well with RVs. This is a 12-Volt battery for both starting and deep cycle, meaning it can work as well for getting your RV on the road as it does for supplying power to the cabin (though shouldn’t be used for both at the same time). With 870 cranking amps and 55 Ah, it provides more than enough to get an RV’s engine started or to run 5 washing machines for one hour.

A vibration-proof battery with 120 minutes reserve power and suitable for starting in bad weather, it’s a great option for those who want to ensure they aren’t left in the dark when trekking the wilds. It can be charged by connecting to the vehicle’s alternator or solar charging system, taking little time to charge. It requires very little maintenance and should last upwards of a decade without too much issue. It’s also very light at 43.5lbs so it’s no hassle at all to drive around.

  • Fifteen times more resistant to vibration for durability
  • Reserve capacity of 120 minutes for constant performance

2. Renogy Deep Cycle AGM Battery

Renogy Deep Cycle AGM Battery review

The Renogy Deep Cycle AGM Battery

A little less expensive than the Optima Batteries product, this is solely a Deep Cycle battery, meaning its used to power the cabin and any other appliances plugged into the electric system. It’s a great deal longer lasting, however, with a 100 Ah in total. It’s leak-proof and spill-proof, meaning that it can be maneuvered and stored in any position with no cause for concern. It is, however, a little heavier at 60lbs, so installing one or two of these to the RV can add a little extra strain.

These batteries are built to store power from solar energy sources and 200 W of Renogy’s solar panels is more than enough to keep them fully charged throughout the trip, provided the panels catch enough light to keep them going. This battery requires very little maintenance and proves no issue to charge or recharge, making it suitable for those who want a complaint-free battery instead of the more delicate, fussy products out there. However, they are a degree larger than many other batteries on the market, so you need to check the battery space of the RV and compare it to the measurements provided to ensure they fit.

  • Avoid over - discharging batteries, especially when they are in series connections.
  • Charge the batteries with recommended voltages, ensure the battery can be fully charged.
  • Generally, recharge capacity should be 1.1 ~ 1.5 * the discharge capacity.
  • The effect of temperature on cycle charge voltage: - 4 mV / °C / Cell.
  • Length of cycle services is significantly affected by depth for discharge (primarily), along with ambient temperature, discharge rate, and the way the battery is recharged.

3. Universal UB121000-45978

Universal UB121000-45978

The Universal UB121000-45978

Another Deep Cycle AGM battery, also providing 100Ah. It’s also shock and vibration resistant, spill-proof and mountable in any position, and relatively maintenance free. It’s slightly heavier than the Renogy battery at just over 63lbs but is slightly smaller. While it might be more of a hassle to transport, it more easily fits into smaller battery spaces.

The price is one of the greatest draws. As the least expensive battery on the list, it’s great value for money, able to power a wide range of appliances for a significant period of time. However, some users have noted that cells have shorted unexpectedly. While we haven’t experienced that, it’s worth keeping in mind that the lower cost may come with some drawbacks. Regardless, it consistently powers up to 100 W all day and can even reach up to 1500 W for short periods of time with no major voltage drops. Saving money on a battery can free up funds for other accessories like an upgraded mattress or quality RV cover.

4. DieHard 38217

DieHard 38217 review

The DieHard 38217

A versatile battery that’s well-suited to work with a range of vehicles. Shock and vibration resistant, with an enhanced electrolyte suspension system, it’s a reliable and durable piece of equipment. An AGM battery with Cranking Amps of 850 and a 92 Ah rating, it provides slightly less power than the other AGMs mentioned above, but not too much less. It should still be well-suited for powering a range of RV appliances and devices like televisions and RV antennas.

One of the best qualities of this battery is that it’s able to sustain high levels of performance in hot and cold weather without significant voltage drops, which is a common problem in other batteries. It’s worth looking at the size of the battery and your RV’s battery space, however. As it’s built for a wide range of vehicles, including cars, some RV users have noted that it’s a little too small to be used in their own.

However, if it does fit, it might be worth considering for that extra reliability. Besides the heat-proof, tamper-proof, vibration-resistant protection, it has a reserve capacity of 170 minutes, meaning that when it’s fully charged, it can discharge 25 Amps for that long without voltage drops, more than most RV users are going to need.

5. Odyssey PC680

Odyssey PC680 review

The Odyssey PC680

Another battery with a non-spillage AGM design and a sturdy design that means it can take plenty of punishment without suffering from significant voltage drops. It’s a much smaller battery than the rest, able to provide 16 Ah or 170 CCA. It’s not enough to power anything on its own for a significant period of time, but might be just the additional source of energy that you need for your RV. Where it becomes a lot more convenient, however, is in its fast recharge time and longer life cycle. It can be recharged and reused many times without starting to suffer any issues and can get a 100% recharge in around 5 hours.

It may not be the right replacement for your primary deep cycle battery, but it might be just what you need if your current battery isn’t providing the Ah you need, and you desire a slight boost. What’s more, it’s highly versatile, so when it’s not being used to power the RV, it might work just as well as a supply of starter power for the motorcycle or for other smaller vehicles.

What you want from an RV battery

We’re going to take a look at some of the top RV batteries on the market. To help judge which is best out of them all, let’s work out what you should be looking for when reading the reviews or scanning the market on your own:

Capacity and power: There are two metrics worth paying attention to when choosing a battery. The cranking amps are how much power is used to start the vehicle, so you want a battery with more CA than the engine demands. Ah, which stands for Ampere hours, shows how much power they can deliver for an hour, so a 75 Ah battery can provide 75 amps for an hour. If you’re using less than 75 amps, it drains more slowly, if you’re using more, it drains faster. Figuring out how much power you need, whether you need a new starting battery or one for general use, is important. Bear in mind that you can install several batteries to the RV, both for starting and general electrical system usage.

Deep cycle or starter: RVs require more power than the average car, so they need a higher depth of discharge to keep everything from water pumps to microwaves to refrigerators. Whereas a starter battery is used to provide a powerful but brief jolt to start the engine. Good deep cycle batteries last longer than starter batteries, on average.

Type of battery: There’s a distinction to be made between the three most common types of deep cycle batteries. Flooded lead-acid batteries lose the mixture of water and acid over time and need to be refilled. Valve regulated lead-acid batteries are more expensive but require virtually no maintenance. However, they do take longer to recharge. The third type is AGM (or Absorbed Glass Mat), a type of lead-acid battery with a fiberglass mat that requires less maintenance and has a slower self-discharge time. They can sit idle for a longer period without any damage.

Other useful features: There are other advantages worth considering when looking at the different batteries available. Size and ease of installation is important, as is vibration resistance since RV drives can get bumpy especially if you’re trekking into the wilderness.

Conclusion

Most of the batteries here have their own role they excel at but it’s the Universal, Renogy, and Optima that are worth the closest look. Out of the three, the Renogy’s slightly larger and heavier than the Optima, but those extra Ah and the fast-solar charging capabilities are well worth looking at. If you’re buying on a budget, however, the Universal might just by the RV battery for you.
