What You Should Know Before Buying RV deep cycle batteries

Deep Cycle Battery

Deep cycle batteries are also known as “deep cell” batteries, which means that they’re good for use in varying temperatures. Unlike regular car batteries, deep cycle batteries can be discharged and then recharged without damage to the battery.

Deep cycle batteries are most commonly used in RVs and marine boats. They can’t be used to start a car, like regular batteries because they will quickly lose their charge and die within minutes or even seconds if put under the strain of having to turn over an engine. Deep cycle batteries also aren’t meant for high power/ high drain appliances. Using a deep cycle battery for this will shorten its lifespan.

Key Difference Between Batteries for RV, Campers and Trailers

Necessary to think about owning the type of RV, camper or trailer you want before you can make a purchase. The main difference is between camping with an RV and dry camping. Dry camping is when you do not have access to electricity and water for your RV, so you need to be mindful if your RV has all the right heating and battery set up to survive in the wild. There are many things to take into consideration when buying an RV and they will vary by the owner’s lifestyle because what the individual needs may be different from another person.

Understanding what type of camper or trailer is right for you should be based on what kind of experience you would like to have while sleeping in it. For example: if someone likes taking long road trips then purchasing a camper would be a good option, but if someone just wants to go to the lake for a weekend then renting an RV or trailer and taking your own vehicle would be better.

Camper

A camper is smaller in size than an RV and usually has two double beds, a table that converts into a bed, microwave, sink with running water and toilet (porta-potty). A camper can also come with air conditioning, a refrigerator and heating.

RV

An RV has more space than a camper and can sleep up to 8 people if needed which means it is great for larger families or group of friends who want to go on an adventure together. The kitchenette in an RV may have your typical appliances like the microwave, oven (not all models), refrigerator and a sink, but the main difference between an RV and camper is that it has a bathroom inside. Having your toilet, shower and sink all in one area offers convenience if you plan to stay somewhere for 2 weeks or longer (something you can’t do with a camper).

The type of roof depends on which type of RV you are buying. The roof can be made of fiberglass, rubber or metal. Each type comes with pros and cons but the main difference is cost, weight capacity and insulation qualities.

Another factor to consider when deciding on an RV is whether it will be used for long distance travel (highway) or short distance travel (city). This will determine weather or not you’ll need to have the higher end model that includes air conditioning and many other factors.

Trailer

A trailer is a perfect choice if you do not plan on traveling long distances because they are lighter in weight and travel shorter distances at slower speeds. The smaller trailers are pulled by an automobile that has a hitch. Trailers can be used to haul camping equipment, watercraft or riding lawnmowers. Larger trailers generally have wheels and travel on the highway.

Trailers come in all shapes and sizes from tiny pop-ups to motorhomes (RVs) that sleep as many as 14 people. They can even come with a rooftop AC unit, fireplace and space to park an automobile.

Trailers are also built for a specific purpose. For example: some people will travel in their pop-up camper which is essentially a tent on the top of a trailer that has beds inside while others choose to use it as storage for large items.

Some people choose to use trailers as RVs. Trailers can be quickly changed into a more permanent living situation by adding plumbing and insulation. This allows the owner to take their home with them wherever they decide to go just like an RV would do.

RV Battery Sizes

There are several different size battery options for your RV, there are the typical 6 volt batteries and also 12 volt batteries. The 6 volt battery was once standard on RVs, but newer vehicles do not come equipped with this type of battery.

When you purchase a new RV battery it will be labeled as either 6 volts or 12 volts. Both sizes have advantages and disadvantages. The 6 volt battery is lighter weight for installation and easier to move around for servicing. However, the disadvantage is that they last fewer charge cycles, which means more replacements throughout the lifetime of your RV. The 12 voltage battery lasts more charge cycles than a six-volt counterpart, but are heavier and take up more space in your RV.

The 6-volt size is commonly found in smaller RVs with a low amp draw, like pop-up campers and travel trailers. This type of battery can be placed in the trunk underneath the motorhome bed or inside the engine bay of an RV that does not have a large amount of electrical equipment. These smaller RVs do not need the extra capacity of a 12-volt battery and the additional space used to install one is not necessary. These 6-volt batteries can be found in most department stores and walmart, so they are easy to find for replacement or new construction.

The 12-volt size is common in RVs with high amp draw, like Class A motorhomes, 5th Wheels and the larger travel trailers. The 12-volt size battery is lighter than an equivalent 6-volt battery but does not last as long due to its smaller capacity. These batteries are found in RV dealerships and other parts dealers that sell RVs, but they can be expensive when purchased new.

The 12-volt RV batteries are usually the standard battery size in marine and automotive applications due to their higher performance in high amp draw equipment.

Questions and Answers About RV deep cycle batteries

Is deep cycle battery better than the rest?

When it comes to RVs – yes. A deep cycle battery is different from a car battery because it stores energy in a much bigger area, and has thick plates for more surface contact, so that the chemical reaction will not stop as quickly. It gives longer-lasting power than starting or “cranking” batteries used in cars. Deep cycle batteries are better at powering big electrical loads like motors and refrigerators without going dead quickly when compared to standard car batteries that typically start an engine only once per day.

How to pick a compatible battery charger?

Pick a charger that provides the amperage required by your battery’s specifications. It is important to make sure your battery operates at its optimal level, so not only should you use the right voltage, but also a charger with enough amps.
All of our chargers come with an amperage rating. Be sure to check the amp rating of your battery. In general, a battery’s amp rating should be at least equal to or greater than the charger’s amp rating.

What is made up of a battery kit?

An RV battery kit consists of a set of lead-acid automobile batteries and a set or cables, clamps and connecting hardware. The kit is designed to provide the power supply for people who travel in recreational vehicles that are primarily powered by electricity. Such materials are used to convert the AC power from the generator to DC power. They are also used to store the electrical energy generated from solar panels or wind generators.
