A Little Background

All vehicles run on a kind of battery. The RV battery is an integral part of your vehicle because without the RV battery, it will not run properly. The gasoline is just a way to make the engine run, but for the rest of the vehicle, such as the lights and the electronics, it is important to have a fully functioning RV battery so that it will not be in trouble during the darker hours or during those emergency situations.

An RV is a kind of vehicle that is used for summer outings. This coming spring and summer vacations, it is important to have a good traveling vehicle – whether you are off the coast or in national parks, or you just want to travel across states in America or wherever you live. These vehicles are very useful if you want to travel as far as you can and still get the luxury of home.

RVs are perhaps the best way to do it, since you get the amenities that you want without having to live in a gross state all the time and look haggard. They are mostly used during times when the sun is mostly out and you don’t want to camp in a single tent that might be too small for your group. For bigger family occasions or road trips, we suggest a RV instead of just a simple tent.

Checking your battery is necessary for every trip. Remember that vehicles with lights can save lives at night, so it is important to get your vehicle’s battery checked at all times before and after you go on a trip, and even if you just wake up in the morning and go back home at night without using your vehicle at all. This applies not only to regular vehicles but also to RVs out there.

Vehicle maintenance is usually abbreviated as BLOWBAG (or BLOWBAGETS in other countries), which stands for battery, lights, oil, wheels, brakes, air, gas (engine, tire and self). All of these are important, and battery is one of them. Remembering this acronym can not only save your car or vehicle, but it can also save many lives and traffic issues around the world. While the parts of the vehicle are important to check, you also need to be alert yourself when driving.

RV batteries are usually much more powerful than regular vehicle batteries. Some RV batteries can even be used for marine applications, such as in boats. This is why RV batteries will most likely be deep cycle batteries that can be a little bit pricier than your regular vehicle batteries for a car or van. These storage cells are important for maintaining your RV, especially at night when lights and electricity are very much needed by your travel companions.

When you’re buying  a battery, it is important to look at the manufacturer date to make sure it’s not defective or expired. The problem with the RV battery is that it is not only pricey but also can be a bit hard to find. This is why you need to look closely at the specs of the RV battery to make sure it is not expired because this will make your vehicle malfunction in some way.

Factors to Consider in the Best RV Batteries

In choosing the best RV battery, you have to know about the following:

Battery size: the size is important because if you do not pick a properly fitting one, then that will be a waste of money. You should use the option of Amazon to check the fitting of your storage cell for the RV to make sure it fits with your model or specific vehicle. Many people make the mistake of buying the wrong size, and this causes problems with returning the product.

Manufacturing date: the biggest factor that decides whether RV batteries are good or not is the manufacturing date. It is true that RV batteries can go bad if they have been in the storage for a long time, and they may lose charge. This is why you need one ideally fresh from the factory, with the date when it was made and the date it will potentially expire, ensuring freshness.

Universal or maker-specific: while it is true that most RV batteries are basically universal or can fit into any kind of vehicle, there are some that are specifically made for a brand or maker of these vehicles, so you may need to consult your user’s manual if your recreational vehicle needs a specific battery instead of a universal one. This can potentially save you more money, should the vehicle be okay with cheaper, universal ones.

Physical condition: you have to consider the physical condition of the battery, so that it will work properly with the contacts of your vehicle’s battery compartment. It is important to have a properly working battery in terms of both physical and internal condition so that it will not damage your vehicle, especially in the contact part, to make sure that all other storage cells will act normally when you install it.

Deep cycle: Get a deep cycle RV battery. Unlike a regular vehicle, an RV takes a lot more power than your usual car or van, and this is why it should be powerful with a deep cycle nature for the recreational vehicle storage cell. You have to take not of this when you are choosing the best RV batteries.

Ease of installation: the installation method of the RV battery should be simple and straightforward. If you are not knowledgeable with installing the storage cell then you can ask a local mechanic or someone who knows how to install it. As compared to most car jobs, it is usually a lot easier, but because it should be fitted in a recreational vehicle, installing the recreational vehicle cell may be depending on what is indicated in your user’s manual.

Q: What are some misconceptions about car batteries?

A: A deep cycle RV battery can be costly if you buy them, and this is why you need to take good care of them properly. Here are some common myths and misconceptions when it comes down to car batteries:

“Maintenance-free batteries do not need any maintenance.” It is not always the case, because you still need to check for any physical signs of wear and tear, which is crucial because if your electric storage cell gets damaged then it might affect the performance of the electric storage cell itself as a whole.
“You can fully recharge your RV battery by idling or driving your vehicle.” Not always the case, because fully recharging can be influenced by different factors, such as the weather. For instance, if you consume more electric storage cell power on a very cold day to start your vehicle, it won’t really make the cut for the full charge for your vehicle’s electric storage cell overall.
“You should disconnect the electric storage cell in case you need to leave your car for a long time.” Not a good idea, because it might make the electronic components fail much later on if they don’t have a power source, especially if your vehicle has a computer box, which can be sensitive. You should just charge it with a maintenance charger instead.
“Anyone can replace the car electric storage cell by themselves.” Replacing a electric storage cell takes some skill and knowledge of automotives – it’s not just something that some guy can do. If you are not sure how to exactly put your electric storage cell in place, you’d better get someone to install it for you, for safety purposes.
