Using a hybrid car as a donor for battery jump start?

j0sh1rish · 16th April 2022, 03:25

Hi
I am a member of this forum, but currently in the US.
I have 2 cars - new Toyota RAV4, and old Honda Civic.
My old car battery discharged due to a light staying ON. I have cables to jump start, but I wasn't able to find instructions on how to use the hybrid car as a donor car to jump start. (I tried looking online/manuals, but wasn't able to find clear instructions). Ultimately, I resorted to using a battery pack to jump-start.

Does anyone have experience with this? Any help is appreciated.

With hybrids coming to India, this information could be useful for members.

I own an Accord Hybrid and recently when I needed to do jump start, I used the jumper cables and used the regular battery under the hood to connect and the car came to life in a second. It was just like any other regular car. Hope that helps.

Just make sure you connect to the correct poles. Connect Plus to plus on the plus poles of both car batteries first.

Then the minus on the donor car battery. Finally connect the other end to a good earth point on the car with the flat battery. This is to prevent sparks on the battery that could ignite the gasses.

Let the donor car run on a fast idle and start the car.

Thanks to you @bhardwhu and @Indian2003 for your replies.

However, the hood does not expose the battery.

The hood has a fuse box that looks like the attachment.
