Frequently Asked Questions (FAQ)

What is the best lithium deep cycle battery?

It's hard to beat the options from Optima for quality, reliability, and value. With a 60-month replacement warranty, these batteries will last a long time and won't cost you a lot more for peace of mind.

The VRLA technology that makes these batteries safer and more preventative of spillage and leaks can also mean a slight decrease in overall battery life, but not enough to make them untenable for anyone who needs a lot of battery power.

In terms of overall reliability, their Dual-Arc Technology and spiral-cell technology make these batteries hard to beat. While they might be a bit pricier than other traditional deep cycle batteries, they are worth the cost for the increased efficiency, reduced maintenance, and warranty.

What kind of battery does an RV use?

RV batteries are lead-acid deep-cycle batteries. They’re a little bit bigger than a car battery, but they should fit where your car battery fit.

Lithium-ion batteries are a new but promising technology. They have higher energy density than traditional lead-acid batteries, so they’re often found in hybrid automobiles. However, they have a shorter life cycle than lead-acid batteries, and as such, are less effective for RV use.

Deep-cycle batteries are what is typically used in RVs. They’re designed to be fully drained multiple times, and to provide bursts of energy over long periods of time. This is different from traction batteries whose job is to deliver quick bursts of energy.

Are lithium batteries better for RVs?

Lithium batteries are the trendiest type of battery right now, largely due to their high-energy density, which is why manufacturers use them in high-drain devices like laptops and cell phones. They can both hold and produce a lot of energy in a small package. They are also very lightweight for their capacity.

However, lithium batteries and lithium-ion batteries are two different things. Lithium-ion batteries are far more common and are what you have inside your laptop and cell phone. Lithium batteries, on the other hand, are a type of lithium-ion battery.

RV batteries are lead-acid batteries and not lithium, despite the fact that they’re also lithium-ion batteries. This confusion often leads to purchase the wrong battery for your RV.
