How to Jump Start a Hybrid Battery – 2023


Hybrid vehicles are becoming increasingly popular due to their fuel efficiency and environmental benefits. However, like any other vehicle, they may encounter battery issues from time to time. In this article, we will guide you on how to jump start a hybrid battery in case of emergencies.

1. Understanding Hybrid Batteries

Hybrid vehicles have two types of batteries: a conventional 12-volt battery and a high-voltage hybrid battery pack. The 12-volt battery powers the vehicle’s accessories, while the hybrid battery pack provides power to the electric motor. It’s important to distinguish between the two before attempting to jump start.

2. Locate the 12-Volt Battery

The 12-volt battery is usually located in the engine bay or trunk of the hybrid vehicle. Consult your owner’s manual to find the exact location. Once located, ensure that the vehicle is turned off and the ignition key is removed.

3. Identify the Positive and Negative Terminals

Before jump starting the battery, it’s crucial to identify the positive and negative terminals of the 12-volt battery. The positive terminal is usually marked with a “+,” while the negative terminal is marked with a “-.” Use caution and wear protective gloves when handling the battery.

4. Connect the Jumper Cables

Connect the positive (red) jumper cable clamp to the positive terminal of the 12-volt battery. Then, connect the other end of the positive cable to the positive terminal of the assisting vehicle’s battery. Next, connect the negative (black) jumper cable clamp to the negative terminal of the assisting vehicle’s battery.

5. Connect the Negative Cable Safely

Unlike traditional jump starting, hybrid batteries require an additional step to ensure safety. Instead of connecting the negative cable directly to the negative terminal of the 12-volt battery, connect it to a solid metal ground point away from the battery. This prevents any potential sparks near the battery pack.

6. Start the Assisting Vehicle

Start the assisting vehicle and let it run for a few minutes to provide sufficient power to the hybrid battery. This process allows the hybrid battery to charge gradually without overloading it with a sudden surge of electricity.

7. Start the Hybrid Vehicle

Once the assisting vehicle is running, attempt to start the hybrid vehicle. If successful, keep both vehicles running for a few more minutes to ensure the hybrid battery receives enough charge. If the hybrid vehicle doesn’t start, wait a few more minutes before trying again or seek professional assistance.

8. Disconnect the Jumper Cables

Once the hybrid vehicle starts, carefully disconnect the jumper cables in reverse order. Start by removing the negative cable from the solid metal ground point, followed by the negative cable from the assisting vehicle’s battery. Lastly, detach the positive cable from both batteries.

9. Let the Hybrid Vehicle Run

Allow the hybrid vehicle to run for at least 15 minutes to recharge the hybrid battery fully. This will ensure that the battery is no longer relying solely on the 12-volt battery, which may have been depleted during the jump start process.

10. Preventive Measures

Jump starting a hybrid battery should be considered a temporary solution. To prevent battery issues in the future, ensure regular maintenance of the hybrid vehicle, including checking the 12-volt battery’s health and charging the hybrid battery according to the manufacturer’s recommendations.


Knowing how to jump start a hybrid battery can be valuable in emergency situations. However, it’s important to approach jump starting with caution and follow the proper steps to ensure safety. If you’re unsure or uncomfortable with the process, it’s always best to seek professional assistance to avoid any potential damage to the hybrid vehicle.
