Top 5 Best RV Battery Reviews (Updated May 2018)
Everything inside an RV is reliant on a system function that works on 12 volts. Without the RV, appliances in the rig are not going to work. The batteries in the RV house are deep cycle ones which are made for storing power so they can still function even after a long time.
In order for the battery to last a long time, you need to have a basic knowledge of what it is and how it functions. The batteries for RVs are lead acid ones, which means they contain a number of cells linked in series. Every cell gives about 1.2 volts, which means a 12-volt battery that has 6 cells in a series has 12.6 volts. This kind of battery are made from plates, lead oxide and lead before being submersed in electrolytes composed of 36% sulfuric acid and 64% water. This kind of battery stores electricity instead of producing them. The total charge of the battery is determined by the lead plates plus how much electrolytes are in there.

You need to know the right RV battery products before buying so you will not end up wasting money.
Things to Look for When Selecting RV Battery
- Never let the battery run when it has less than 50% of charge. If this happens, recharge them right away and it they go lower than 20%, they will be damaged. This can cause them to never work again. You can make a battery last for 7 years if you religiously follow this rule
- A battery with 12 volts is normally the main battery, which is for supplying electricity to RVs and other appliances, like the lightning, pump, and fridge. The main battery can be created by using one 12-volt battery or taking 2 6-volt batteries and wiring them together. Both of these contain 2.1-volt cells, the 6-volt batteries have three cells in each battery and the 12-volts have 6 cells.
You must know that batteries with 6-volts have a larger size, but they are much lighter compared to a battery with 12 volts. There is a habit of RVers to opt using 2 6-volts to have only one power source, because this is known to be more long lasting, and it doubles the voltage.
Although, it does not add to the amp-hours. The reason behind the longer life span are the thicker plates and there is added space for every cell, which has a better discharge compared to a 12-volt battery deep cycle. If you are thinking of wiring one series of 12-volt batteries, it would be necessary to add voltage and hours of amps.
- Check the technology that was used to make the battery because it should be lead-acid. Otherwise, it cannot be used for RVs. The basic battery is referred to “flooded cell” because the lead has been bathed using liquid water or a solution with acid. The good thing is that the newest models are maintenance free to lessen electrolyte loss by closing the cells, except for a small vent hole. Although, this does not work if you heavy charge the battery too often.
Aside from that, a get type that uses thick paste electrolyte with a good sealant is becoming a top choice. One popular choice for a main RV battery is the 6-volt size
- Since RV batteries are a big investment, you must know how to store them properly to prolong their life. You should store them when the condition is right and keep in mind to never store them when they are discharged. This will cause the battery plates to crystallize making them hard. When this happens, they will no longer be able to supply power. To get your battery ready for the next trip, the battery has to be charged every 3 months
- To properly maintain the RV battery, it is better to prevent anything from happening. You should not wait until the battery already has corrosive deposits before cleaning it. When the battery is in this state, there is too much damage already so clean regularly.
When you are cleaning the battery, wear old clothes and wear skin and eyes protection – protective goggles and gloves. One drop of acid from the battery can lead to serious damage. Take a toothbrush or wire brush, baking soda and water to balance the corrosion, then the terminal connections have to be cleaned, together with the clamps that link them together. When you are done with this, rub on grease or petroleum jelly so that terminals and cables are cleaned, which will slow down corrosion formation
