In the future, we will be looking at this battery pack technology and laughing about how overcomplicated and inefficient it is.

Brilliant guide. So many people replace the full battery pack on their Prius' when it's not needed.

As others have said... thank you for sharing your experiences of how to go about this repair project ..great!

You are brilliant every aspect. Great Camera man!! Educational video starting from highschool students learning technology all the way to retirement and beyond. THANK you so much.

Thanks for sharing your experience. It will assist me if/when I need to work on the battery of my wife's Prius.

Thx for taking time to show us, very instructive. I was expected to find out a connection at each stage of the battery for cell balancing. Apparently its not the case with these NiMh battery.

Well done. Pretty helpful info and i just get to know the looks of the hybrid battery. thank you so much.

I have a 2015 kia optima hybrid hopefully the schematics are similar thank you very much sir this was very helpful and interesting to learn from instead of paying $1000

Excellent, it has been fantastic to watch your video extremely informative easy to follow and it has allowed me as a layperson to understand how the job can be done.

Great Job Mr. Mosleh ..Thank you so much

Fantastic explanation and very informative thanks

Thank Imam, great video, can you list the tools and sizes that would be a great help. Keep up the good job, thank you for the good video again.

Hint for removing the cells. Once you have the pack on your workbench, before you remove the tan end-cap and after you're disconnected all the leads (the orange side attachment deal) turn it up on it's end cap and remove the 8mm/phillips on the bottom while the end-cap is still on. That way you can get to all the bolts underneath easily w/o risking dropping any cells b/c the end-cap keeps them all in place. On my battery, cells (from the connection end) 12 and 16 were bad so I just unbolted cells 12-28, laid the pack back down and then took off the end-cap.

Ah, a good point at 12:50.  Compress the battery so the holes on the bottom line up.  Excellent video.  Thank you.  (edit, 3:20) Did you know that the compression plate is on facing the wrong way?  The bottom tension bolts can't tighten that way unless you modify the plastic tabs coming off of the bottom of the plate.  Att to viewers.  And you're counting from the wrong end.  Start your count from the other end.

Great video and good explanation. Thank you.

Thanks for your help I’m doing this today!

Very Interesting and professionally compiled.

Great video & camera work tks

Thank you for the great video. I have a 2009 Prius, hopefully won't have to do this while I have this car, but very helpful knowing it can be done.

Your video very clearly. Thanks for show us
