An RV battery differs from the usual car battery because an RV battery must supply enough power to be able to not only support the engine but also the non-engine systems such as water pumps, lights, and a whole host of other appliances that need to be powered over long periods of time for the full duration of your trip.

It can be difficult to know which RV battery is the best, but you’re in luck because we have constructed this guide to show you the best battery for RV’s that is currently on the market to give you the peace of mind that you will have the highest quality and top performing solution.

To the naked eye, RV batteries look extremely similar to a traditional car battery, however because an RV has a larger engine it requires more power to start so these batteries have higher Cold Cranking Amps. This makes it easier to start the larger engine.

Additionally, RV batteries supply a slower steadier supply of amps over a longer period of time, whilst they are more regularly discharged from the vehicle to be recharged fully and then returned to the vehicle, which is often referred to as deep cycling.

The best deep cycling batteries can last up to four times longer than a typical RV battery when it is placed under the same conditions.

For these reasons it’s easy to see why the best RV batteries are designed to have deep cycling and lower power because it means it is long lasting and performs better than a typical engine starting battery.

Lead Acid technology is a superior feature that essentially means that the lead inside the battery is covered in either an acid solution or liquid water. This means the battery is maintenance free so you have to do less to ensure that your battery continues to function effectively throughout its life.

Deep cycles are measure in the unit of Amp Hours which means the total number of amp of power that can be delivered in a 20 hour time window. An alternative measurement is reserve capacity which translates to the number of minutes that the battery can maintain a 25 amp load. In simple terms, the higher these numbers are the better

There is a key difference between 6 volt and 12 volt rv batteries and it is incredibly important to understand the difference between the two as it shows how long the batteries will last for in between each charge, which links back to amp hours. 12 volt batteries are better suited to RV drivers that prefer to hook their vehicle up to electrical outlets because the battery has a shorter periods between charges.

On the other hand, 6 volt batteries have a longer run time in between charges which means that they are more suited to RV drivers who prefer to not hook the vehicle up to electrical sources.
