1. What are the different types of RV batteries? Which one do I need?
There are two types of batteries for the RV: Engine batteries and house batteries. Believe it or not, you will need both batteries for an RV. Recreational vehicle require both house batteries and a startup battery for its engine.
House batteries are meant to provide power to an RV or other vehicle for long periods of time. Engine batteries are meant to help jump-start the car so that the car goes from off to on in just a few seconds. Think of engine batteries as sprinters while house batteries are marathon runners.
2. What is the best charger for the RV battery?
Deep cycle batteries have unique needs when it needs to recharge and maintain power. However, if there are charged according to a schedule that prioritizes in temperature and chemistry dependency, they will charge quicker and last long than usual. With that said, a “Smart charger” is created to handle fluctuating charging schedules of deep cycle batteries for the RV.
You will also need a battery charger that has what is called a “maintenance float phase” so that the battery can be prevented from losing any electrolytes.
3. How can I charge an RV battery with solar panels?
There are also solar powered battery charger that require nothing but sunlight. They are also cost-efficient, silent and environmentally-friendly.
To power your RV battery from the sun, you will need to purchase a solar RV battery charger. The big benefit to these types of chargers is that they do not require electrical power in order to run.
4. How to charge RV battery while driving?
To charge a deep cycle RV battery while driving, you must first begin with the VCR, also known as the voltage controlled relay. VCRs can instantly disconnect and can be used to parallel auxiliary and starter batteries.
When the relay on the VCR is closed, the two batteries become paralleled. The relay opens when the RV starts. Then, the RV batteries become disconnected once you turn the RV off, adjusting the voltage to a fixed level.
Your RV’s power source is also considered a battery. Connect your deep cycle battery to the power source, and use high quality plugs and cable in order to connect the two. High quality plugs and cables are capable of transferring large amounts of energy, and also ensuring that the connections are safe and secure. As long as the battery is securely connected, it will not deplete any energy.
It is important, however, to not overcharge the battery. When you mistakenly overcharge an RV battery, observe the level of electrolytes and add some distilled water to the battery. Be sure to check your batteries often, especially during harsh weather conditions.
5. How to install an RV battery disconnect switch?
Installing an RV battery disconnect switch onto your RV is a rather painless and simple task, although if you are used to doing a similar task with other equipment or technology, it could instead be confusing, such as connecting the positive side of the battery to the negative side of the switch.
Instead, all you need to know is to be sure to attach the positive side of the switch directly attach to the positive side on the battery.
The negative side of the switch should be connected to a circuit breaker or fuse. This will prevent any power surges that the RV might experience. Some assembly processes will connect the switch to the negative side of the battery, but this procedure has not been confirmed by specialists in the battery industry.
6. How long does a deep cycle RV battery last?
An RV battery can last in between three to ten years, depending on multiple factors. The first factor is the quality of the battery, where a good quality battery is sure to last longer than a mediocre-quality battery.
Secondly, the usage is another thing to consider. If you use the battery too often or not often enough, the battery will tend to die sooner than later. Using the battery regularly and appropriately will guarantee the longest life possible.
Thirdly, the quality of the motor is also a factor. If you have a powerful and aggressive engine and/or motor, the battery will require more energy than a smaller engine and/or motor.
Proper care of your battery is important when attempting to make it last as long as possible while serving you and your RV.
