Best RV Batteries to Buy in 2018
When you are getting an RV, the last feature that you and many people consider is usually the battery. Ideally, people trust the original RV batteries to last for years on end and never think that a time will come when they will need to replace the RV batteries. Yes, batteries since there are some RVs that feature multiple batteries.
If yours is a motor home, your RV will feature the chassis battery that starts the engine and at the very least a 12V deep cycle house battery or two 6V deep cycle house batteries. If yours is a travel camper or trailer, you will only have a deep cycle battery/batteries. The original RV batteries are sufficient to meet the needs of an average RV user. However, depending on the RV lifestyle that you lead and your personal reference, you just might have to start looking for a spare, and one of the best RV batteries on the market.
Several reasons that could have you replace your RV battery or even upgrade, may be the lack of maintenance or a failure on the converter and hard use. Also, it could be caused by cannibalizing of good batteries by connecting them to bad batteries or you may be looking for an upgrade. Whichever your reason for needing a new RV battery, you should work to ensure that you have the best on the market.
For this, there are several things you will need to know and many factors you will need to consider. We shall go through some of these factors on this piece. We shall even provide you with reviews of the best RV batteries on the market to help light your path and make the decision-making process, a breeze.
Difference of RV Batteries with Other Batteries
#1. Large CCA
When you are choosing your RV battery, the most important bit to consider is the CCA. In RV batteries, the CCA refers to Cold Cranking Amps. CCA is the measure of just how much current the battery has the ability to provide at 0 degrees Fahrenheit. Generally, RV batteries tend to work best when they are warm and as such you need slightly more power to get them started.
With the aging of batteries, the CCA reduces as their internal resistance increases. The capacity with time decreases and you find the old unit cannot serve in the cold or if not fully charged. New units can, however, work wonderfully regardless of the weather. With a higher CCA, you are guaranteed of better performance.
#2. Deep Cycling
Unlike regular batteries, RV batteries require a specific type of power to run all appliance that it has in it. For this, RV batteries are designed to have deep cycles. Deep cycle batteries are designed with Lead acid which stores power for a long time. The plates of deep cycle batteries also store a specific amount of power.
As such, the more plates the battery has the more power you have. These batteries are designed to charge and self-discharge. As such, you can recharge these units a couple of times before you need to replace them.
Last but not least, in comparison to regular starter batteries that need quick jolts of power, deep cycle batteries store power much slower and through deep and long cycles.
#3. High-Temperature Variation
Generally, RV batteries are designed to operate in wide temperature ranges. However, this does not give you the luxury to charge them at extreme temperature conditions. The charging process is especially more delicate than the discharging process and care should be taken.
Older batteries technologies including NiCD and lead batteries (deep cycle batteries) have a much higher charging tolerance than newer battery technologies. These tolerances allow them to be charged even below freezing temperatures though at a considerably reduced C-rate.
What's Best Battery Types for RVs
#1. Home Battery
A home battery is an important component for any RV since it provides for the base motivation of many of the RV living conveniences. So to help get rid of the confusion, home batteries are commonly referred to as deep cycle batteries that store 12 volts of direct current.
They have been designed to recharge and discharge several times (a couple of hundreds) without getting damaged. The capacity is measured in amps hours and generally, range from 33 – 20 and weight between 50 and 70 lbs depending on the type. Home batteries can last up to 4 times the normal starting batteries.
- Provide energy for a longer time
- Larger CCA rating
- Last longer than normal starting batteries
- Might be quite expensive
#2. Normal Auto Battery
These are relatively smaller than the house batteries. And while they are needed on RVs, they serve a different purpose – to start the engine. They are smaller than house batteries and have slightly smaller CCA as well. The fact that they are used to start the engine means that they provide short bursts of energy to get the engine going and recharge immediately in the process. As such, normal auto batteries may last their entire life without ever discharging to lower than 20%.
- Do not need to discharge considerably
- Thin Lead plates do not allow them to last for ages on end
#3. Marine Battery
These are a hybrid of deep cycle batteries and starting batteries. They tow the line not being great in doing what deep cycling or starting batteries do. They tend to be less expensive than the actual deep cycle batteries, though.
But even with the fact that they feature both deep cycling and starting battery designs, they are suitable for use in RV battery situations.
- Can be produced as starting batteries are
- Are less expensive
- Have a relatively deep cycling performance
