Can I Jump an Rv Battery With My Car

Last Updated on March 8, 2023 by Ryan

Yes, you can jump an RV battery with your car. You will need to connect the positive (red) terminal of your car’s battery to the positive (red) terminal of the RV battery and then connect the negative (black) terminal of your car’s battery to a metal surface on the RV that is away from any moving parts or fuel lines. Make sure both vehicles are turned off before attempting this.

Once connected, start up your vehicle and let it run for about 5 minutes before trying to start up the RV. After starting up the RV, allow it to idle for 10-15 minutes in order for its alternator to recharge its own battery.

  • Park the car close to the RV, making sure that both vehicles are in park and have their parking brakes engaged
  • Open the hoods of both cars and locate the batteries
  • The battery terminals should be clearly marked with either a “+” or “-” sign, indicating positive and negative respectively
  • Take jumper cables from your car’s trunk (or glove compartment) and connect one red wire to the positive terminal of your car’s battery, then take another red wire and connect it to the positive terminal of your RV’s battery

  • Connect one black wire to negative terminal on your car’s battery, then take another black wire and connect it to an unpainted metal surface away from any other wires or components in order to ground out any stray current while jumping your RV’s dead battery
  • Start up your car first before attempting to start up your RV; this will help reduce any damage caused by voltage spikes when starting up a stalled engine

How to Jump Start a Motorhome

Jumping a motorhome can be a daunting task, but it doesn’t have to be! Before attempting to jump start your motorhome, you should make sure that the battery is actually dead and not just low on charge. If it is determined that the battery needs to be jumped start, you will need another vehicle with a working battery and jumper cables.

Connect one end of the red cable (positive) to the positive terminal of your motorhome’s battery and then connect the other end of that same cable to the positive terminal on the donor vehicle. Once both vehicles are running, start your motorhome’s engine; if successful remove all connections in reverse order before turning off either vehicle.

How to Jumpstart a Diesel Motorhome

If you need to jumpstart your diesel motorhome, the process is slightly different than for a gasoline vehicle. To prevent damage to the fuel system, it’s important that you use a second battery with jumper cables or a power pack specifically designed for diesel engines. Make sure that both batteries are in good working order and connected securely before attempting to start the engine.

It may also help to rev up the engine of the donor vehicle prior to engaging its starter; this will ensure maximum energy flow when starting your motorhome.

How to Start Rv With Dead Batteries

If you find yourself with dead batteries in your RV, there are several steps you can take to get them running again. First, check the battery and make sure it is not completely drained or corroded and needs replaced. If it does need replacing, do so before attempting any further steps.

Next, try starting the engine by jump-starting with another vehicle or using a portable battery jumper pack. Alternatively, if neither of these options is available to you, use a generator to charge up the batteries while they’re connected directly to your RV’s electrical system. Finally, once the batteries have been charged enough for starting purposes, connect them back up and start your engine as normal!

How to Jump Start Batteries in Series

Jumping batteries in series is a relatively simple process that can save you time and money when faced with dead battery problems. To do this, you will need two jumper cables, one of which needs to be connected to the positive terminal of the first battery, followed by connection to the negative terminal of the second battery. Then connect the other end of the cable from positive on second battery to negative on first battery.

Once all connections have been made, start your vehicle and allow it to run for several minutes until both batteries are charged sufficiently for use.

How Do I Charge My Rv Battery With My Car?

To charge your RV battery with your car, you’ll need a few items. First, you will need jumper cables to connect the positive and negative terminal of the car’s battery to the corresponding terminals on your RV’s battery. Once connected, start your vehicle and allow it to run for at least twenty minutes so that its alternator can transfer power from the car’s engine into the RV battery.

Make sure all lights or other electrical appliances are turned off during this time as excessive drain could potentially damage both batteries. Finally, once charging is complete disconnect in reverse order (i.e., first disconnect negative then positive) before turning off either vehicle – failure to do so may result in sparks which can cause personal injury or fire danger!

Can a Car Battery Charge an Rv Battery?

Yes, a car battery can charge an RV battery. The process is very similar to the charging of any other type of lead-acid battery and involves connecting the positive terminal of the car battery to the positive terminal of the RV battery with jumper cables and then connecting the negative terminal of either one to an unpainted metal surface on your vehicle’s frame as a ground. It is important to monitor both batteries during this process since overcharging or undercharging could cause damage.

Additionally, it’s best to use a voltage regulator when charging an RV battery from a car in order ensure that it does not get overcharged.

How Do You Jump a Motorhome Battery?

Jumping a motorhome battery is fairly simple and can be done in just a few steps. First, make sure you have the right jumper cables and that they are securely attached to both batteries; the positive cable should attach to the positive terminal of one battery, while the negative cable attaches to the negative terminal of another. Next, start your engine and let it run for at least five minutes before attempting to jump-start your vehicle.

Finally, turn off both vehicles’ engines, then reattach each end of the jumper cables back onto their respective terminals on either side of the motorhome’s battery. Once complete, start up your engine again and hopefully you will see an improvement in starting power!

Is It Ok to Jump-Start a Motorhome?

Yes, it is generally ok to jump-start a motorhome. However, you should always make sure that you are using the correct type of jumper cables and that they are properly connected before attempting to start the vehicle. Additionally, you should use caution when connecting the cables as some motorhomes have multiple batteries which need to be linked in order for them all to receive sufficient power.

Finally, if the battery does not respond after several attempts at jump-starting it may indicate a more serious issue and further diagnosis or repair may be needed.


This blog post provided a comprehensive overview of the process for jumping an RV battery with a car. It is important to take safety precautions when working on electrical systems and to make sure that you have all the tools necessary before attempting any repairs or maintenance. Additionally, it is essential to use the right cables in order to ensure that your vehicle’s battery does not get damaged during the jump-starting process.

Overall, with this knowledge, you can safely jump start your RV battery if needed without having to worry about damaging either your car or RV’s batteries.
