7 Best RV Deep Cycle Batteries

Have you ever been in a situation where, in your RV, you’re unable to charge your phone, have proper ventilation or enjoy fresh air on a hot night just because you’ve run out of electricity? I was.
Worse still, you had to lessen the time used on the phone just because you know there is no alternative electricity source. Feels weird!
A good RV battery must have a powerful resistance capacity to keep your device’s Power ON over a long period.
One of RV batteries’ most important features is that they are designed for continuous discharging and recharging, which supports the typical RV’s condition.
If your RV has several electronics, investing in the following 7 best deep cycle RV batteries can help.

Buyers guide

What Are The Factors To Consider When Buying A Deep Cycle Battery For RV?

Capacity

Capacity, rated in ampere-hours, is the specific amount of current that a battery can deliver within a certain time. For example, a 200AH battery will deliver 200A in 1 hour.

Batteries with high capacity store more Power and last longer. In a nutshell, the higher, the better. Also, remember to check the size and weight of the battery for storage purposes.

When choosing battery capacity, make sure you consider your energy requirement. Measure your daily power input.

Here’s also good news: some battery supports solar power recharging.

Quick tip- If you’re planning to go off-grid, make sure you choose a battery that can support you for the long term.

Discharge depth

The depth of discharge is another critical factor to consider when buying a deep cycle RV battery. Discharge depths are usually measured in percentage. Deep cycle batteries usually have a higher discharge depth.

Voltage

Voltage measures the electrical differences. A typical deep cycle battery has a voltage kg 12V.

Some PV owners even connect 2 6 volts batteries in series to equal the 12V requirement of a deep cycle battery. Just make sure you consider your RV system when doing this tweaking.

Remember, most charging kits are configured to work on 24V batteries. So you need a power booster to convert DC to AC for an effective battery function.

Charging methods

Another factor to consider is how you want your deep cycle battery to be charged – is it through the generator, solar, or shore power?

You can even combine these three.

Withstand vibration

An RV deep cycle battery’s ability to withstand vibration is an important factor to consider before buying an RV deep cycle battery. Batteries that are built to be strong and sturdy tend to withstand vibration.

Make sure you go for batteries that are shock and vibration resistant.

All the deep cycle batteries reviewed above are shock and vibration resistant. Going for batteries without this feature might cost you more money on repairs in the future.

Frequently Asked Question

This section answers the most frequently asked questions from potential buyers.

What is an RV deep cycle battery?

Water pumps, Air conditioners, microwaves, and a lot of appliances in the recreational vehicle depend on RV batteries for operation. And that’s because they provide current consistently.

These batteries are designed to discharge into 70% of their total capacity.

What are the types of RV batteries? Which is best for me?

Deep cycle batteries are commonly used for recreational vehicles. And that’s mostly due to their designs – deep cycle batteries can withstand frequent recharging and discharging.

Engine starting batteries cannot last as long as the deep cycle battery.

The lightweight lithium battery is the best and most popular type of deep cycle battery because it is maintenance-free.

However, it is costlier. Gel, conventional flooded gel, and absorbed glass mat are other great options.

Which charger is the best for an RV battery?

RV batteries have a battery charging system. But some of them perform poorly.

Some are designed to top up the battery—however, some batteries damage from overcharging.

That’s why you should be careful with the type of charger to use.

Converter chargers are the best type of charger to use for your RV battery. They convert 120 volts of shore power to 12 volts DC power.

Conclusion

All the RV deep cycle batteries reviewed are the best in the market. Our editor’s choice is the Optima 8016-103 D34M deep cycle battery.

It is a dual-purpose battery (functions as a deep cycle and a starting battery), easy to use and maintain, shock and vibration resistant, delivers maximum power electricity, and lightweight (despite its high voltage).

If you’re looking for a deep cycle battery with rugged construction and long battery life, our runner-up, the Odyssey PC680 Battery, is a great choice.

Our budget option is the WindyNation 100AH 12-volt AGM. Overall, all of our reviewed products are unique in their ways.
