Jumpstarting A Hyundai Ioniq

While it can be dangerous, jumpstarting your Hyundai Ioniq is a straightforward task. To do this, you'll need a set of jumper cables and another working vehicle to help you. Once you have everything, you need you should position the functional vehicle close to the dead car.

When setting up the vehicles, it's crucial that they aren't touching each other. You want them close enough that it's easy to work, but that's it. If they're too close, you can damage your cables because too much electricity will flow between the cars.

Connecting Jumper Cables

It is essential that you connect your cables in the correct order. If you don't, there are a lot of things that can go wrong. You can cause an explosion or fry the electronics.

When connecting your jumper cables, first make sure that both cars are off. Then, you should follow these steps:

  1. Connect a red (positive) cable to the positive terminal on the car with the dead battery.
  2. Next, connect the other end of the red cable to the positive terminal on the working vehicle.
  3. Connect the black (negative) cable onto the negative chassis ground on the car with the working battery.
  4. Finally, connect the other end of the black cable to the negative chassis ground on the car with the dead battery.

Keep in mind that the newest Hyundai Ioniq models don't have a traditional battery located within the engine compartment. The manufacturers moved the battery to make room for other components.

However, the negative and positive terminals that you need are still located under the hood. Take a look at this video to see what you can expect.

Starting the Vehicles

Once you've safely connected the batteries with jumper cables, you're almost ready to start your vehicles. First, you'll need to push the 12V Battery Reset Button on your Ioniq. After you press it, you can start the engine on the other vehicle.

Let the engine run for a few minutes before attempting to start the car with the dead battery. After this time has passed, you can try to start your vehicle.

This should be enough for your car to start. If you've tried a few times and the car still isn't starting, you'll need to take it to a mechanic.

Disconnecting The Cables

The order you disconnect the cables is just as important as when you put them on. You'll need to do them in the exact opposite way you set them up. These are the steps:

  1. Disconnect the black cable from the Hyundai Ioniq.
  2. Disconnect the other end of the black cable.
  3. Do the same with the red cable from the assisting vehicle.
  4. Finally, you can disconnect the other end of the red cable from the Ioniq.

You'll need to keep your car running after it's disconnected from the other battery. If you shut your vehicle off before the battery gets a chance to charge, it may not start up again.

To make sure you don't face the same problem, leave your car running for at least 30 minutes. You can either drive it around or leave it in "ready mode" in a stopped position.

Jumpstarting the Ioniq Plug-In Hybrid

You can jumpstart the Ioniq Plug-In Hybrid in the same method as listed above. However, there are a few key differences. Here are the steps for jumpstarting this particular Ioniq:

  1. Position the vehicles so they're close but not touching.
  2. Connect the positive cable to the positive jumper terminal on the Ioniq.
  3. Then, connect the other end of the positive jumper cable to the positive terminal on the helping car.
  4. Connect the black jumper cable to the negative chassis on the helping vehicle.
  5. Connect the other end of the cable to the negative chassis on the dead car.
  6. Start the assisting vehicle and run it at 2,000 RPM for a few minutes.
  7. Start the vehicle with the dead battery.
  8. Disconnect the cables in the reverse order you connected them.

As you can see, the Plug-In Hybrid can be jumpstarted in a very similar way. The most crucial difference is monitoring the assisting car's RPM.

How Long Does A Hyundai Ioniq Battery Last?

The Ioniq has a lithium-ion battery that needs replacing less often than the batteries in your gas-powered vehicles. You can expect the Hyundai Ioniq battery to last anywhere from 6 to 10 years.

How Long To Fully Charge A Hyundai Ioniq Battery?

The Hyundai Ioniq takes approximately an hour to charge the electric Ioniq from 0% to an 80% charge. These speeds are capable at fast-charging stations supplying 100kW of power.

If you're using a standard AC charging station supplying 11kW, our Ioniq will charge from 0% to a full charge in approximately six hours.

Is Hyundai Ioniq Hybrid Self-Charging?

Yes! The 12V battery on the Ioniq is integrated into an HEV high voltage battery. The HEV battery will generate energy through a regenerative braking system. This means that every time you brake, it converts to energy, which recharges your car battery. Don't expect your battery to recharge while it is set to a neutral position, though.

In addition to self-charging, you can plug in many Ioniq vehicles to charge. Please check your manual to see how your car battery regains power.

How Do I Know My Ioniq Battery Is Dead?

You'll start noticing some problems with your vehicle before the battery dies on you. A change in efficiency tends to be the first thing people see. You may also notice incorrect readings on your charge level. If your battery level randomly goes up and down, you likely have a battery issue.

Another thing to be on the lookout for is your battery not holding a charge at all. If you start noticing any of these things, it's time to get a battery checkup. Take your vehicle to the nearest mechanic to see what should be done.

How Much Does It Cost To Replace A Battery In A Hyundai Ioniq?

Unfortunately, replacing the battery on your Ioniq isn't going to be cheap. A lot more work goes into replacing a hybrid battery than there is to replace a gas-powered car's battery.

So, what's the cost to replace a battery for the Ioniq? The cost of labor and parts will vary depending on your location. However, you can expect to pay around $300 for labor. The battery itself can range from $2,000 to $10,000. 

Those numbers tend to be for a brand new battery. With hybrid vehicles, you have the option of refurbishing your battery. This means that you can replace some or all of the cells that are a part of your battery, saving you money in the long run.

This will significantly reduce the price of fixing your battery. Refurbishing your hybrid battery will cost less than completely replacing it. The price varies here as well. It will depend on how many cells you want to be replaced.
