Can I use a car battery in my RV?

While no laws or rules state that you cannot use a car battery, it is just simply not recommended. They typically don’t have enough power to last for a while, they are unable to be recharged like a deep cycle battery can be, and they can also be expensive to rely on.

Are RV batteries the same as car batteries?

Deep Cycle Batteries Unlike a traditional car battery, deep-cycle batteries provide a long, steady stream of power. It can provide a short burst of power, but nothing like a car battery. Deep cycle batteries are also lead-acid batteries but they are designed to be discharged and recharged regularly.

What kind of battery does an RV use?

lead acid batteries
Batteries used in RVs are lead acid batteries, which means they have several cells connected in series. Each cell produces approximately 2.1 volts, so a 12-volt battery with six cells in series produces an out put voltage of 12.6 volts.

Can you mix battery sizes in an RV?

We strongly recommend you DO NOT attempt to mix battery sizes (amp-hours) and connect together. This will cause the highest voltage battery to charge the lowest voltage battery attempting to create balance in the circuit. The greater the difference in voltage, the higher the probability of battery failure.

Can I use a normal car battery for camping?

If you want to run appliances, devices and lighting in your campsite you’ll need a deep cycle battery, it’s not recommended to use your vehicle’s starter battery.

Can I use my car battery for camping?

It is ok to use a car battery for camping but you should not think of it as a primary source of generating electricity. To power appliances, fridges, etc you’ll need a deep cycle battery if you don’t want your car battery to drain to the point where you can’t even start your car.

What is the difference between a Group 24 and Group 27 battery?

If you compare a group 24 battery and group 27 deep cycle battery together, you’ll notice that the mp hours are slightly higher on the group-27 product. This specification difference is made on purpose by the manufacturers. In general, a group size with a higher number has more amp hours than lower values.

What’s the difference between a regular car battery and a deep cycle battery?

Car batteries are specially designed to provide a short, sharp burst of power in order to crank over and start the vehicle’s engine. Deep Cycle batteries are constructed using thicker battery plates and a denser active material, to withstand repeated charge and discharge cycles.

What is a group 27 deep cycle battery?

Group 27 batteries are rather large and powerful batteries, featuring 20h capacity in 66-110 Ah range, providing 600-1000 CCA, 140-220 minutes RC, etc. Their weight depends on the internal construction and it ranges between 54 and 70 pounds (24.5 – 32 kg).

Can you parallel 2 different batteries?

It’s generally not a good idea to put batteries in parallel because one can be more charged and have a higher voltage and this will cause it to drain quickly as it feeds the other battery. No two batteries are identical, even if taken from the same pack or same production run.

Can you mix old and new RV batteries?

Mixing different batteries is never a good idea. First of all, mixing batteries which are different in type, size, brand or voltage will not even work. If you were to mix a new battery to an old string or a new string to an older bank, the new batteries would reach their state of charge sooner than the older batteries.

Will a 12V cooler drain my car battery?

Conclusion. There is absolutely no question – a fridge cooler will drain you car battery. On average, fridge coolers will draw 4.5A at 12V. As they are thermostatically regulated, you can expect the compressor to be running about 25\% of the time.

What kind of battery do I need for an RV battery?

The battery or batteries used to supply 12-volts to the RV itself are commonly referred to as house batteries. House batteries need to be deep cycle batteries that are designed to provide a steady amount of current over a long period. Starting batteries and marine batteries should not be used in this application.

How long do RV deep cycle batteries last?

A fully charged RV deep cycle battery would last depending on how many appliances you run on it. A RV battery is rated in terms on amp-hours. A standard RV deep cycle battery would be rated at around 100 amp hours. What this really means is your appliances can use either 1 amps for 100 hours or say 2 amps for 50 hours.

What size battery does a diesel motorhome have?

A typical diesel engine RV will have two 12v batteries wired in parallel and having a rating of 900-1000 CCA each. That large a CCA usually means the battery case size is a Group 31.

What is the difference between Ah and RC for RV batteries?

For house batteries, the power is measured in either amp-hours (AH) or reserve capacity (RC). AH refers to how many amps the battery will put out over a 20-hour period, while RC refers to how many minutes the battery can support a 20 amp output. RVServices.Koa.com elucidates how these measurements work in greater detail:
