Best 12-Volts RV Battery: Overview
A battery is an electrochemical device that converts chemical energy to electrical energy and vice versa, depending on the cell type. It stores electricity for future use.
Also, a battery consists of electrochemical cells. These cells could either be rechargeable or non-rechargeable.
More so, the non-rechargeable cells are called primary cells, while the rechargeable cells are called secondary cells.
Furthermore, you can not recharge a battery with primary cells. Once the battery goes down, you discard it.
In this case, the battery only converts the chemical energy stored into electrical energy.
On the other hand, you can recharge the secondary cells. Thus, you can use it more than once.
Both rechargeable and non-rechargeable cells operate on the same principles. They consist of two electrodes (anode and cathode) submerged in an acidic solution called an electrolyte.
Furthermore, the electrolyte reacts with the anode to produce electrons around the anode, while the cathode reacts with the electrolyte to accept electrons. These electrons tend to find their way to the cathode.
However, the semipermeable barrier obstructs the movement of the electrons to the cathode through the electrolyte. Thus, leaving the external terminals and conductors as the only electron route.
When you connect a load to the battery, the electrons move from the anode to the cathode through the load. As a result, a direct current will flow through the load.
However, this reaction occurs in reverse when recharging a battery (for rechargeable batteries).
RV batteries are rechargeable batteries that power recreational vehicles. They could either be a starter battery or a deep cycle battery.
More so, the deep cycle battery could be flooded lead-acid, absorbent glass mat (AGM), gel cell, or lithium (LiFePO4) batteries. Aside from the gel cell that has gel electrolytes, others have liquid electrolytes.
Best 12-Volts RV Battery: Pros And Cons
The advantages of 12-volt RV batteries are as follows:
- If you have two 12 volts RV batteries, you can use one to run the recreational vehicle if one of them fails.
- Also, 12-volt deep-cycle RV batteries are often more affordable.
- Even so, they are readily available.
- In addition, each 12V battery you connect in parallel adds more ampere-hours, and you can connect as many as you want.
Although 12-volt RV batteries have a lot of benefits, their drawbacks include:
- The 12-volt battery gets bigger with its ampere-hour rating. Thus, it might become heavy.
- Also, it could be less durable than 6V batteries.
- Even so, it might not fit into a small battery storage area.
Best 12-Volts RV Battery: Factors To Consider
When buying a 12-volt battery for your recreational vehicle (RV), there are certain points you need to note to get the best. These points include
The Rating Of The Battery
The rating of the battery shows how much capacity it has. However, this battery rating is expressed in amp-hour.
Thus, it tells you how much current the battery will supply to your recreational vehicle (RV) for one hour. You can further determine the energy it provides with this information.
Nevertheless, you do not need to worry about knowing the battery’s rating. This is because most batteries come with the rating boldly displayed on them.
Type Of Battery
The types of batteries used in recreational vehicles (RVs) are starter and deep-cycle. Each of these batteries is useful for different purposes.
More so, the deep-cycle battery could be a flooded lead-acid battery, a gel cell battery, an absorbent glass mat (AGM) battery, or a lithium battery. However, flooded lead-acid batteries are mostly used in recreational vehicles (RVs).
Furthermore, some RVs, like campers and trailers, often have a single electrical system, while motorhomes can have up to two for the engine system and the coach.
Thus, deep-cycle batteries are commonly used in trailers, campers, motorhomes, etc. They have a great capacity and can provide power throughout a long camping trip.
On the other hand, starter batteries are also used in some RVs. Since you do not need to deeply discharge them, they are used in the engine electrical system in motorhomes.
In some motorhomes, the engine electrical system uses a starter battery, while the coaches’ lights and various accessories use deep-cycle batteries.
Some batteries require more maintenance than others. For example, due to the liquid electrolyte in lead-acid batteries, they need more maintenance than lithium batteries which requires none.
Thus, the maintenance of the RV battery is another point you should note. Hence, you should go for the lithium battery.
However, the lithium battery has a higher initial cost than lead-acid but becomes more cost-efficient over time.
More so, lithium batteries are lighter and do not emit toxic fumes. Even so, it does not require ventilation.
The expected life span of your battery is another important point you should note. For instance, a lithium battery can last up to 10 years or more.
However, gel cell batteries and many lead-acid batteries may last 2 or 3 years. This depends on several things anyway.
Nevertheless, you need to check the warranty of the product to ensure that your battery will last long. Since you do not need to spend on another battery within a short period.
Price Of The Battery
The cost of the battery is another factor you should consider. A high-quality and durable battery is expected to be more expensive than others.
Thus, if you have a tight budget, you may need options with lesser prices that might not be so durable.
