Can I Jump An RV Battery With My Car? [Yes/No]

Can I Jump An RV Battery With My Car

The answer entirely depends on your car type and the size of your car engine. Besides, you need to have previous experience with jump-starting any car.

Therefore, if your car’s engine is small, then don’t even try to jump an RV battery. It will create nothing but a complete disaster. So, the question might arise, how do we know what car or engine to use? 

Well, let’s make things clear. For example, your RVs’ engine is a 7.3L V8 with 350 hp. So, the car you’re using to jump should be at that minimum level or closer around. 

The car’s engine must be large enough and have enough power to jump-start an RV battery. And usually, only RVs and big trucks have that kind of big engine.

But more importantly, you need to figure out what type of batteries you are dealing with. 

Jump-starting your battery might affect your car or engine long-term. There are a couple of things that you should keep in mind.

Things To Keep In Mind Before Jump-Starting An Rv Battery

Not knowing how to jump-start an RV battery properly might damage your car. And this could also be a reason for getting injured as well.

Here is a list of a few things you should know before jump-starting an RV battery with your car.

  • Are you familiar with the positive and negative terminals of the batteries? If not, then don’t even try to jump-start the RV battery. 
  • One of the most common issues is when your car can’t provide enough power for your RV. If you are using a vehicle with a small engine or low energy, likely, RV won’t get enough power to start. 
  • This sudden power drop might damage your car’s engine or many other components. Besides, sudden energy surges could also create electric shorts in the engine area. So, be careful about that.
  • There is also long-term damage that might cause to the battery. For example, a few weeks later, you might notice that the battery is not charging correctly or providing the energy to the car properly. 

In some cases, the battery could permanently get damaged, and you might need to replace the battery with a new one.

Ways to Jump An RV Battery With A Car

Of course, we don’t want to sit around and wait long to ruin our holiday, right? We need to start to jump the battery ASAP.

Let’s cut it to the chase. You need three things to jumpstart your RV battery.

  1. Any RV/ Big Truck.
  2. Drip Charging.
  3. Battery Jumpers.

Let’s go through them one by one to get an overall idea.

RV/Big Truck

We need a big truck or RV because of the necessary power to jump-start the battery. Trucks or RVs with 300 or more horsepower can quickly jump-start an RV battery. 

Here is a list of big trucks to give you an idea of what type of trucks we are talking about. Trucks with more than 300 hp (or around) are considered to do the job, such as Jeep Gladiator, Nissan Frontier, Ford F-150, GMC Sierra, etc.

On the other hand, RVs with a similar engine power match the RV you’re trying to jump-start. Never try to start-jump an RVs battery car with small engines.

As for the time, it might take a minimum of 10 hours to charge those batteries completely. But in some cases, it might take 40 hours as well.

Drip Charging

Well, in most cases, RVs have a drip charging option. All you need to do is find a wall socket and plug it in. when your battery is running dry, you can just charge it back up.

Don’t let your battery sleep drained for several days. Otherwise, it can completely drain and harm the effectiveness of the battery. Before jump-starting the car, give it some power. Otherwise, the process won’t work.

Battery Jumpers

If you’re doing a lot of RV maintenance, you might already have battery jumpers. Some general and specialized jumpers exist for different categories of RVs and other vehicles.

You will find different types of jumpers with lower and higher voltages in the market. As you’re dealing with big trucks and RVs, you must deal with big jumpers

And, of course, deal with them effectively and efficiently. But experts don’t usually suggest using the jumper cables if not necessary.
