Thanks! This is a truly great video. One of the all time greats of YouTube instructions. Sounds like you ate Mr. Rodgers. I mean that in a good way.

Adding to all the other positive comments, I found these instructions right on the mark. It took me less than 20 minutes to install a new Optima battery. The previous one was 4+ years old and I didn't want to go through the pain of a dead battery when I needed the car the most. I had to have a new Toyota battery put in my 2004 Prius back in 2007. AAA towed me to a dealer that then charged me over $400, which I thought was way beyond outrageous. At least now I know I can replace one myself.

Great Video! Saved me at least $100 for labor at the dealer. I don't work on cars and this was easy! Less than an hour to remove the old battery and install the new OEM spec battery.

I agree. I think the Optima brand is much better than average. It's worth the price !

I reversed the procedure a little bit. I removed the Brake Supply Power Assembly out of the way to make room and get access to the negative terminal. The rest is easy. Excellent presentation. I wish however that you can use a spot light or flashlight to point out and show better those parts. I replaced the original battery with the Optima for Prius 2005. Excellent product and service. I believe that my Prius has discovered its 'soulmate' and is livelier !

Thanks for the slides and instructions. I just replaced my 2007 Prius battery with the new Optima battery made especially for the Prius. I could not have done it without your help. Took me about 45 minutes total. I installed it for free and now know it was done right. THANKS!
