Full disclosure (you didn't have the option).
The vehicle listed above is a RX350H (Hybrid).

I had a guy ask me to help him jump start his car.
I could not find my 12v battery to do it.

No clue how I could help somebody. And I can't find any info online. Where the heck is the battery in this thing?

Thanks in advance.

Thanks for this question. If you open your hood and look on the driver side you should see a fuse box. Open that fuse box and you will see the red cover with a + on it. This is the positive battery cable that goes directly to the battery. Then you will just need to hook the negative cable to any bolt that is attached to the engine block or chassis. This is the same as the ground terminal.

As for the location of the battery, it is in the rear of the vehicle close to the spare tire. Just remove the cover for the spare tire and you should see it.

However, you do not use the actual battery to jump start your vehicle or another one. You can if you want to but the location under the hood would be easier. Let me know if you still can't find it and we can go from there. Thanks
