How to Replace a Hybrid Battery in a Prius (Upgraded Battery)

The safety plug tool being the safety connection is genius

Watching this just in case. Never know when it might come in handy

Chris, you did a great job making this video. The camera positions was perfect. You explained everything. My son-in-law recently purchased a 2011 Prius with 150,000 miles. It needed the batteries replaced but the previous owner opted to sell the car and purchase another vehicle. We watched this awesome video and purchased the batteries used in this video and we installed them yesterday. We took our time and referred to the video several times. Everything fit perfectly and we did not have any issues at all. Being an ex-mechanic, everything was pretty straight forward, but my son-in-law wanted to follow your steps. We even torqued the bolts and nuts to your specs. After installation, the car was charging up the batteries. Thanks again, for this fantastic video and recommending these batteries.

My brother was a master technician for 30 years. You have an amazing talent not only for mechanics but for teaching!!

I’ve done multiple hybrid battery replacement and repairs , I have to say this is the most straightforward and detailed video on YouTube I’ve seen , great job Chris!

I don't own a Prius or plan on buying one anytime soon, but Chris's car videos are just too educational and well-made to not watch. This is some high quality entertainment!

I don't even have a prius, but I watched it from start to finish with full pleasure... Great job on the video, amazing!

Your preparation before filming is spectacular. Scripting to ensure you pantomime to match your voiceover, pacing to make sure sped up parts match the feel of the rest, and overall preparation (research on torque specs, for instance) is absolutely unmatched anywhere else. You also have branding down to a science. This is a must watch for anyone looking to create instructional content.

Damn, this guy is a gem! Nobody on Youtube does instructive car repair videos in detail as well as him.

These videos are without a doubt the highest quality in the industry. It’s incredible how seamless all of his steps are. At times it feels like Chris can see into the future. Fantastic work as always!

Started watching videos on how to detail a car and ended up here... I don't have a car, not even a drivers license, but these videos are so mesmerizing! Chris, hats off to you for going in such details and being so patient and explaining every step! I wish professors in schools had this kind of approach to reaching kids. Great job and keep being awesome! 😊

When my partner starting doing uber, her first week was during train strikes last year. It really made me wanted to start doing it too. But as time has gone on, and I have seen how it really works it’s not for me! It suits her for flexibility, but I couldn’t do it. I travel 3hours for work everyday and I’m as stiff as a board after the journey, I couldn’t imagine 12hours sat in the car like you do. You work hard, well done. And that said, Its my day off today going to book an Uber to go into town! 👍.

Find me one person who wouldn't spend 40 minutes not only learning how to replace the hybrid cells in a Prius, but also experiencing the passion this man has for his job. Shine on, Chris. I know nobody more down to Earth, and no bigger nerd (in the best way) than ChrisFix. Thank you for the years of entertainment.

I'll probably never own a Prius but i still watched the whole thing. It's amazing how you take such an intimidating task and break it down to where it looks easy!

Its crazy to me how far you go the extra mile. There will be a single bolt and yet you still set up an entire shot, Camara, lighting, everything just to get a one and a half second shot of a single bolt. Genuinely, i appreciate that a lot and so mad respect for you for really going the extra mile and then some!

Hey Chris, I'm not a mechanic at all, but because of the detailed process you shared in this video (including the trusted vendor for the upgraded battery), I had enough confidence to attempt swapping out our old hybrid battery on our 2010 Prius myself instead of paying 💰💸 to a dealer or shade-tree mechanic. I spent the extra $500 for the entire pack from Electron Hybrid Solutions instead of just swapping out the cells, and, for me at least, that was money well-spent. There were a few hiccups along the way, but nothing insurmountable. I just filled up the tank today in town and reset Trip A just to see how the new battery is behaving. On the 21.1 mile trip back home, half on the highway at 70+ mph, half on country backroads, I averaged 65.6 mpg. Before the old battery bit the dust, I was averaging about 43 mpg. I'll take a 50% improvement any day of the week. Thank you so much!!! The hiccups: 1. The ratchet straps holding the battery tight in the wooden crate had loosened somewhat during shipment to me, so a couple of the mounting fins had been bent up pretty badly. I was able to gently bend them back good enough to get it properly mounted. I advised the vendor of this. 2. Also due to the loose straps, one brown, cigar-sized piece of electronics had broken off its mount and the square socket end where it plugs in had been broken. I just transferred the same piece off my old battery onto the new one and sent the broken piece back to the vendor with my old battery (notifying them of the situation). 3. Because my Prius had been out of commission for a couple months, the 12v battery had run all the way down, so I had to manually unlock the car and climb back through to the hatchback area to manually release the hatchback door latch to get it open....to even begin work. Also needed to jump start the car to test out the new hybrid battery once I'd gotten it installed. 4. When the Prius first started up after the new battery installation, the "check hybrid system" error had gone away (and no triangle of death), but the entire right side of the dash display was dark. I drove it a bit down the gravel driveway and back, and the car seemed to work fine both with the gas engine running and on electric motor alone, but the right half of the dash remained dark. A quick check of PriusChat indicated that that might happen if the 12v battery runs all the way down. Which mine had. So I parked it for a bit and left the jump pack attached to the 12v battery to give it a bit more juice. Of course the regular driving of the car should charge the 12v up just fine, but I didn't feel it was safe to drive the car around or get too far from home until I had the full dash display back. After about 15 mins on the jump pack charging, the Prius started up with full operational dash and has been fine ever since. Thanks again, Chris! You're amazing!

I swear to god I wished this video never ends. Amazing attention to detail, camera angles, explanations, and so on and so forth. Just perfect.

Chris, it's a master demonstration. I don't own a Prius, but I enjoy the efficient way you explain every aspect of the repair, giving us useful tricks to become better weekend mechanics, It may even encourage me to turn EV after all. Thanks a lot.

I can't imagine a better video to explain how to get this job done. 10 out of 10, well done Chris!

This was EXPONENTIALLY **THE BEST** Automotive repair video I've ever seen! Well done!!!! --Your explanations were perfect: the lighting was spot on. Editing was unbelievably crisp & sharp.... VERY impressive. (No extraneous tightenings, explanations or removal steps, etc.)... the best 40 minutes I've spent in years! Thank you!!!!!
