Need to replace your RV battery? An Odyssey battery review can help you to determine if this brand is the right choice for you and your vehicle. Owning an RV requires regular maintenance, and changing out the battery now and then is just one of the many tasks you need to perform in order to manage the upkeep.

Your RV battery is responsible for powering a slew of necessities, including your lights, refrigerator, air conditioning, and most importantly, getting your RV started. However, with so many options currently on the market, the search can understandably become overwhelming. Knowing what you can expect from an Odyssey 31M-PC2150 Extreme Series Marine Battery is the first step to choosing the best RV battery for you.

What to Look for in an RV Battery

When you're shopping around for an RV battery, there are a few features you want to look for. Primarily, you want to find one that not only suits your needs but one that will also ensure you get the most bang for your buck. Here are the key features you should consider:



Before buying an RV battery, you have to make sure you know what kind you need. Doing this is especially crucial for those who are still new to the camping lifestyle, as there are a few terms you should become familiar with. These are some of the most common types of RV batteries.

Starting battery

A starting battery, also referred to as a chassis battery, is meant to start your RV engine. It offers a substantial amount of power in short bursts, just enough to get the engine going.

Deep cycling battery

When it comes to using the electrical devices in your RV, a deep cycling battery is necessary. Also referred to as house batteries, they supply power for extended periods of time and can last for years. They're referred to as deep cycling batteries as they are designed to be drained almost entirely before they recharge. There are three varieties of deep cycling batteries used in RVs, including Conventional Flooded Electrolyte, Gel, and Absorbed Glass Mat or AGM.

Marine battery

A marine battery is technically meant for water vehicles, but are an excellent option for RVs. As both a starting battery and a deep cycling battery, marine batteries have become a popular choice for use in recreational vehicles. They may not function as well as batteries designed to serve one function, but they tend to be more affordable.



After you've determined the type of battery you need, you'll want to compare lifespans next. While it may seem like choosing the RV battery with the longest estimated lifespan is the obvious choice, there are more points to consider. Starter batteries can have a lifespan that ranges anywhere from 3 to 12 months. Deep cycle batteries can last up to 10 years, depending on the manufacturer and the kind of battery it is. Expect the price tag to be significantly different, though, as the lifespan increases.


​Power rating

An AH rating and RC rating is given to each RV battery, detailing its capacity and expected lifespan. The AH rating, which stands for Amp-Hours, indicates how many amps the battery delivers in 20 hours. The RC rating, which stands for Reserve Capacity, indicates how many minutes a battery can be used consistently at 25 amps. A battery with ratings on the higher end is considered to be of better quality.
