Best Rv Battery – Do NOT Buy Before Reading This!

You’re probably wondering, are car batteries the same as RV batteries? All RV’s need a set of “house” batteries that power the 12 volt needs, as well as a starting battery meant to power the engine. House batteries may be comprised of several batteries wired together whereas the engine battery is just the same as car batteries, except larger. Before rounding up the best RV batteries in the market, let’s first learn the differences between house and starting batteries.

First and foremost, house batteries are designed to provide energy over long stretches of time while engine or starting batteries offer quick bursts of energy aimed at getting the engine going. Here’s a good comparison: if the house battery is a marathon, the engine battery is a 100-meter dash.

RV House Batteries​

RV house batteries are designed for low power and go through “deep-cycling”. These batteries are usually fully-discharged before they get recharged again.

The best deep-cycle batteries may perform better than engine batteries and may last up to four times longer than standard engine batteries under the same conditions.

Users can rate house batteries according to its AH (Amp-Hours) battery capacity which tells the total number of power the battery can deliver over a 20-hour time frame. The bigger the AH, the more powerful the battery is.​

RV Starting Batteries​

The battery used to start the engine is known as chassis battery or a starting battery. These batteries supply significant amounts of starting currents for short periods. They possess numerous thin plates for maximizing the plate area that is exposed to the electrolyte, resulting in the production of large currents in short bursts.

Starting batteries have a Cold Cranking Amps (CCA) rating. CCA denotes the number of amps a single battery can deliver under a temperature of 0 degrees F for 30 seconds, provided that the amp rating should not drop below 7.2 volts. Starting batteries should not be used for deep cycle applications.

Marine Batteries​

There are deep-cycling house batteries, there are starting batteries, then there are marine batteries. Marine batteries are the result of an attempt to mix the characteristics of starting and deep-cycling batteries.

Actually, marine batteries aren’t great as a whole or for either purpose, yet they’re less expensive, and they may be suitable for some situations. They have a lower CCA rating and a greater deep cycle.

RV Battery Technology​

Currently, all RV batteries employ lead-acid technology. However, there are different lead-acid battery packages.

First, we have the flooded cell battery wherein the cell is soaked in an electrolyte solution which diminishes as you use it, requiring the addition of water from time to time.

On the other hand, AGM (Absorbed Glass Mat) batteries are designed to minimize the loss of the electrolyte solution through effective sealing and utilizing sponges made of glass fibers.

We also have the gel type batteries which rely on thick electrolyte pastes and are also sealed firmly like the AGM.

What Type Of RV Battery Should I Use?​

What Type Of RV Battery Should I Use

Your RVing style will determine the battery type you need for your motorhome.

If you have a simple style of looking for a campground then setting up electricity and such, a marine battery will do fine. They’re cheap, and they last quite longer than starting batteries.

On the other hand, if you go through terrains and has a rough camping style, you’ll need a battery with a large capacity such as a good deep-cycling battery. These batteries may run up to 4 to 10 years and costs twice as that of marine batteries.

There’s the 6-volt, golf car battery which is a popular kind of house battery. They are rugged, long lasting, and two sets of it can be wired together to form a 12V source. A 12V power supply is ideal for various household appliances and amenities found in an RV.

Engine-starting batteries are the cheapest 12V batteries available in the market, but they’re not as long lasting as deep-cycling house batteries.

This AGM battery for electrical motors yields an excellent deep-cycle performance rating that can crank a high voltage of up to 13.6 to 13.8 V. Moreover, this multipurpose power source can be used on your boat, motorhome, scooter, golf cart, wheelchairs, and other gadgets.

The AGM technology allows the battery to be mounted in any position and be shock and vibration-resistant. Interestingly, its performance can be regulated by a valve.

We ordered six of these to be installed on our boat for our wayfaring around the Central American coast and we’re quite satisfied with it so far. They were in great shape when we received them, and all 6 batteries had a measured voltage of 12.89 which was very impressive.

After a week of running, the refrigerator, WiFi, LED lightings, and a 12V rainwater pressure pump, the voltage had only dropped from 12.89 to 12.6, which is very negligible by the way. Considering that we also have 5 panels totalling 650 watts running that time to maximize the solar radiation, we were very impressed with this battery’s longevity.

Our only suggestion for the manufacturer of this battery is to make the stainless hardware to be about 1/2" longer. It is about 1" long and can accommodate 2 connections per terminal but any more or thick terminals, you run out of thread.


Pros

  • Lightweight
  • Versatile
  • Recharges fast
  • Starts even in bad weather
  • Long-lasting.

Cons

  • The stainless steel hardware is too short for additional connections
