This video was done perfectly! You managed to mention every little detail without rambling on like so many other youtubers. Thank you...saved myself a nice chunk of change by doing this myself!

People like you are the backbone of KZfaq. Thank you for the excellent video!

Have to agree, straightforward clear perfect style. No extraneous talk, gave mm sizes for the right tools. THANK YOU!!! 500 Stars!!!

My 10-year-old Prius just had its first battery issue. After recharging, I thought the battery was up front, under the connections. I had no idea it was in the back. Now I am positive I can replace it myself. This video was perfect, and super useful. Great work! Thank you!

I thought a dead Prius battery was going to cost me a trip to the dealership and $500. But instead I got a new battery at a parts store and swapped it out myself in 20 minutes -- using your excellent video. Thank you!

Another grateful viewer here! I’ve changed batteries before but was intimidated to do this for my 2011 Prius… watched your video first and it helped so much, the replacement went seamlessly thanks to this guide! Really appreciate the straightforward but clear directions (especially the 10mm mention! it was so cold when I was doing this, not having to mess around finding the right size was a big help) and the great camera angle. Thank you x a million!

KZfaq at its best! Crystal-clear instructions supported by quality camera work and audio. As a noob I especially liked the "inside baseball" ("it's not a j-bolt so it won't get lost") and knowing what tools (in this case "tool") to gather to get the job done. Never did this task before, took my time, and was done in under 15 minutes. Success! Thank you!

This video was SUCH a help! My hubby and I followed and got everything in place perfectly. For a suburban girl, I am super proud!

Great useful video. A few notes I might add based on my experience: * If you can get your car to an auto parts store, do so. They can test your old battery with a load tester for free and they give you credit when you turn in your old battery. * I was unable to get a conclusive test using the red battery terminal under the hood. It was necessary to open up the battery access in the right rear. * Made a misstake. I removed my old battery, shut the rear hatch, and exchanged my old for the new in the store. The issue was that when I returned to my car I was unable to open the rear hatch because the hatch latch requires electricity. With some contortion I was able to get myself and the new battery into the rear of the car from the back door. * The new battery cost me $220 after the core charge credit. * The old battery appeared to be the original. So it had lasted 11 years.

My Prius was having issues starting and it was stressing me out. Did some online research and determined it might be the 8 year old battery. Did it myself thanks to you who made it so much less intimidating! Car starts right up! Thank you!

I replaced my almost 10 year old battery yesterday, and you made it easy by following along with your video. Thank you!

Just got my car to run again, this video is a lifesaver and money saver.

things to add: 1. always disconnect neg first, then positive so your tool will not arch if you make a mistake. Reverse (positive, then neg back) like the video. Would be nice to explain why 2. don't close your lid when disconnected or you will have to craw from the back seat and reach the latch inside to release (electronic lock). 3. recommend using same battery and why (venting in car space, size, AGM for crash/acid reason, etc...). 2x the price though.

I always watch your videos first when i need to work on our Prius. Thank you for clear concise instructions!

A very professionally done video. Concise and to the point with no wasteful yammering like so many other car videos. I have a couple of tips to add. I read that even with the negative cable removed, you still have to be careful not to ground out the positive with your wrench since there's power to the cable from the hybrid battery. Also, it would be a good idea to connect a charger or some other 12V supply (under the hood) so you don't lose your various settings maintained by the battery when you disconnect it..

Thank you for an excellent tutorial. I propped up my iPad in the back of my Prius and followed your video step by step. My car was dead and you helped me bring it back to life. Feels good to be able to fix something.

Easiest video to follow! My Prius started right up after sitting for a year. Right to the point without trying to sell something or jabber too much.

Cool! I ordered a new battery from Amazon and thanks to this video brought my Prius back to life myself without having to take it anywhere. Original battery was dead after 4 years/45k miles. Thank you for the easy to follow instructions.

I never even knew there was a battery in there. Thank you. I thought I had a major problem but it was a simple quick fix. My battery was 11 years old.

My Toyota dealer gave me labor cost of $100 to replace a battery. This video saved me hundred dollars! Very straight forward to replace the battery with in less than 15 minutes. Provided you got the right size spanner tool. Thank you.

I just did the install on my 2010 3rd gen Prius IV, the install took only about 20 min. This video is well done, thank you. Here's my notes I used, maybe it will help you. # Need: 10mm wrench or socket # Battery: Duralast Platinum Battery 46B24R-AGM Group Size 46B24R 410 CCA (autozone delivered in 3 days!) # Ground terminal grounds the entire car, disconnect this first, do the install, reconnect this last. pull tub & floor panels out Remove negative connection Remove bracket bolts Remove bracket, leave grounding wire connected, move aside Remove positive connection Remove vent hose, notice notch Remove battery, remember orientation: negative closest to the bumper # Repeat above steps, reversed. Install new battery, negative closest to the bumper Connect vent hose, get notch right Connect positive connection Place bracket back in place Connect bracket bolts Connect negative connection ** check battery, start car up ** Replace floor panel, tub

What a great video! Clear and to the point, no endless rambling. I just used it to replace the battery of my Prius and it worked as a charm. Keep up the good work and thank you!

My Prius 2015 12V battery just dies on me and I need new battery...Thanks so much for sharing this video sir 👍🌻

Thank you for this clear and concise video without the unfocused rambling that comes with most of these instructional videos. Thanks to you, I saved $200 by installing the battery myself.

This is the best video on do it yourself on you tube. It made quicker to install the battery. 😊

Watched your video and saved $150 to replace the battery on my 2013 Prius. Great video and thanks for saving me money.

Thank you SOOOO much for this video! It was my first time changing the battery in my prius and your instructions and even listing the tools were such a huge help! Went to the store and got everything I needed and changing it out only took less than 20 minutes.

Disconnect the native cable first is the KEY point, thank you.

loved the simplicity. No jargons and no nonsense. Thank you for your effort. Very useful video !

Thank you for making the video. My 2013 Prius would not “Start” when depressing the brake and press the Start Button; it would be in “Accessory“ mode. I took it to the dealer and found out that the battery was weak. They wanted $390 for the battery and labor. I asked how much is the battery itself , it was $262 (after returning my old battery). I asked them not to install but that I would buy the battery. This video gave me the confidence that I could do this so thank you. The positive cable was really stuck for me, but I was able to do this.

That video was great!! My Prius battery is 10 years old, and I think it is time to replace it! That sure did help me understand how to do it without a lot of extra time spent on frivolous things.

note : this is the same for a 3rd gen prius type 4 ( the plugin prius )

Thank you for a concise straightforward instruction. I wish all the instructions were this spot-on. Have a great day, sir!

Thank you so much for this video! Your step-by-step explanations made it comprehensible for a non-automotive person like myself.

Great video. It was very helpful. Here's a tip, once you pull the old battery out don't close the hatch, it locks. I removed the old battery and closed the hatch and drove my other car to the part store to swapped it out with a new one so I could get the core refund. The hatch lock needs the battery to unlock. I had to entry the car from the backseat to install the new battery. If you are a big guy that might not be too easy.

Thankful to find this, had my wife’s battery changed in about 15 minutes thanks to this guide

Really straightforward video. I am now ready to tackle my 2011, 7 year 4 month old original battery. Good job!

Hey buddy, thanks for doing this demonstration! Not only saved me money but time as well since I didn’t have to schlep back and forth to local garage. Best part was I didn’t have to worry that the Prius motor would shut off halfway to garage and I’d have to jump it again. And again. And again… Seriously, thanks!

Nicely explained... this video helped me a lot to replace my Prius' 12 V battery. FYI to others, if your battery is fully discharged then you can take it to O'Reiley's who will recharge it for free overnight... Thanks for the video.

Great video. Was able to perform this service thanks to your explicit and accurate directions.

Thanks. This was helpful. We have a 2015 Prius. My wife usually drives it. So had the key fob in my pocket, touched the driver handle to unlock and the horn starts blowing, weakly. I used the key fob to deactivate antitheft and get into the driver seat. Put my foot on the brake, then pressed the POWER button and the LED turns amber. On the display it showed aux battery low. Did not attempt a jump, assumed the 12v batt was toast. After research, looking at this video, I decided it is an easy DIY. Downloaded the procedure from the Toyota.com owner webpage. Replacement battery used is the highly rated Optima Batteries model DS46B24R. Unfortunately, was unable to open the rear hatch, so had to work form inside the car. Folded down the back seats then was able to remove everything as in the video. Confirmed, only had to set date and time, radio and of course ODO settings were preserved. On a side note, the 12v batt is used to power up the ECO and ancillary electronics. The ECU in turn starts the engines.

Great video, straightforward! One question... Will I lose any important data or settings in the car's computer when the battery is unhooked? Do I have a limited amount of time to get the new one hooked up?

I know nothing about cars but i’m about to do this for my prius. Thank you for this tutorial!

Well Done on this video! Loved the fact you mentioned the Wrench size, and sped up the screwing/unscrewing of the bolts and nuts!

Thank you so much for this video! As luck would have it we purchased the same battery before even looking at your video😂 Your instructions were perfect, and I was able to get the battery swapped out in no time!

I am glad I watched this and did change the battery myself. Thanks for all you do.

I called 4 places in South Florida today. Advance Auto Parts charges $195 for battery (no installation) with 3-year warranty. Toyota dealer (Deerfileld) charges $199 (installed) with 2-year warranty. Batteries Plus charges $199 (no installation) with 4-year warranty. Costco does not sell the auxiliary battery. I'm stumped -- the only difference is the warranty... I may as well go to dealer, it seems. Your video makes it seem super easy - I was ready and willing to do it myself!

I should've watched this video before coming to the dealership

Got the confidence to change my 2013 battery today thanks to your video. Thanks for the valuable demo!

fantastic video....to the point, good details and no rambling

It’s insane to think free YT videos are better than actual mechanic training courses from years ago that cost big money.

Well done! I bought the same battery, AGM type for $200. Perfect fit in the Prius V 2015. I understand traditional lead-acid is not good for Prius. It took 30 minutes. The + terminal was tight but I got it off after some pulling. Did not lose any settings. My battery was 6 years old, OEM and registered 11.6V on the car's diagnostics. I decided 6 years was enough.

It doesn't need a battery keeper to prevent losing learned computer settings, stereo security code and so forth? Maybe the larger battery does that?

I followed the instructions here and it made it really easy for me, so thank you! I have a 3rd gen Prius. The only thing I was nervous about was closing the hatch door after removing the bad battery. I feared it would lock with no way to unlock it. Maybe it can't lock without a battery so my fears may have been misguided, but I didn't want to take any chances. I left it open while I went to the auto parts store to process the old for new battery, otherwise, there would have been an extra core charge.

Thank you so much for the video. Currently bought a Prius and getting to know the basics of my prius.

FYI these batteries are deep cycle, not standard batteries and are harder to find. Also, AAA does not sell these batteries. And they are roughly half the size of a standard battery. I just paid $260 at autozone.

Old lady from Australia says thank you about to do the task now

Nice kept it simple.. to the point.. I like the 3rd generation Prius better for changing the battery.. easier than a second generation.. I got 216000 miles on mine.. I use the Mobil 1 extended life.. the car is tight as the day I got it..at 122k.

Dude, perfect video. Clear, concise and straight to the point. Excellent video!!

Excellent. Short, concise and to the point ! Thank you.

Another excellent video. I followed it and got the car fixed. i love this guy. I used a AGL replacement which even had the vapor exhaust tube fitting.

This video royaly saved me today when my battery died suddenly and I had to change it in auto store parking lot since they wouldn't. thank you

Thank you for this video. Just replaced my 10 yr old battery with ease.

Best instructional video. No extra gibberish talks.

Clutch! Heading over to my mom's to pull her battery and needed to know which tools to bring along.

Sweet & Simple & Precise.... your video makes things nice!!! Thanks for taking the time to do this!!!

Thank you for a clear, sensible presentation.

Great video, wish I had seen this prior to paying $418 to replace one at Toyota Canada :(

Your vid's are a lifesaver. LOL! Seriously, thank you so much for creating them.

Thanks for video, matched the process. Just did it in about 10min total.

Thanks for the information. After connecting my new battery, I opened the car door and the alarm went off. Had to push the unlock button on the remote.

such quality video and graphics and explained simply for newbees!!

Just followed this vid to replace the 12v in my 2014 Prius, perfect walkthrough! Thanks!

I just want to add that when you change the battery out...don't panic when your car won't start. It has to download some data first. Takes maybe 3-5 minutes. I just changed my battery and it's a piece of cake...except for taking out a few things to get to it and removing and replacing the vent tube it is just the same as any car.

Thank you so much! I used this video when I had to do the same in my car.

Thanks for the video! Advance Auto Parts had a warning about needing professional installation for this battery, but I couldn't find anything especially hazardous in the Prius Haynes manual. I think the warning is in place because it's absolutely vital to reconnect the exhaust, since it needs external ventilation and could otherwise contaminate the cabin air.

Thank you for posting! I have a Plugin Prius so the entire back floor does not come out (I think half of it covers the plugin batteries), but basically skipping the first 2 steps, the rest about removing the battery from the compartment on the right worked. Thanks again.

Thank you so much! This video was perfect, showing every detail as you did it. There was another video by someone else and I couldn't understand a word he was saying or ever see the work as he did it. You video was excellent. thank you again

Awesome video. I just wanted to make sure I could safely replace one of these on a Prius without damaging the car or getting zapped! 😅❤

My car had been parked for a month. A nice little mouse decided to make a nest using seat insulation right on top of my neg post. I guess it made enough contact with the grounded body of the car. It killed the battery. Lessons learned, you can still jump your car upfront and drive it all you want as long as you don’t cut it off again. I have one of those battery pack jumper things and I jumped it several times using maybe ten percent of the portable jumper. So with one of those you are not stuck. Under the hood in front you take your fuse cover off, there’s a little red cover you flip over to expose the positive (red) connection. Connect black to a bolt anywhere connected to the body or frame of the car. These batteries are not cheap, I just found one just under 200 bucks with turning your dead one in. I learned something today, don’t let a store “test” your battery while it’s still connected in your car. If the apply a load check, it can smoke your very expensive ecm electronic control module. Tell tell sign it’s your 12 volt battery, after you press start that load will shut off all lights on the dash. If your red lock icon is not blinking, with all the doors shut from the outside. It’s likely a dead battery. If you left a door open or light on inside the car, just jump it and drive around for 30 min. Once the car is on, the high voltage hybrid system charges your 12 volt system. If you run it a while and go to restart and find it dead again. It’s likely the battery has a dead cell, be very curious as to why it’s now dead. Ten year old car, I’m not really gonna think too much about it but a newer battery. Those have had something happen, I don’t know like say a stupid mouse nest! Or chewed wire, loose wire etc. great video as always above, thank you and I hope I helped you too with your adventure. If you don’t have one of those small emergency jumper batteries. Spend the 50 bucks, keep it charged and thank me later when it bails you out of trouble. By the way also not, dead battery equals unable to open the hatchback from outside. So you have to put your back seat down, crawl back there and in the middle bottom where it latches there’s a small little latch you pull from back to front relative to the car. So pull latch forward and hold forward, while holding in that position push up on the hatch back to have it come open. A little heavy to push in this twister position you likely find ourself in. Heck maybe I should make a KZfaq video too on my lessons learned today. Anyone wanna go mouse sniping with me. I shall avenge the death of my battery! 200 dollar stupid mouse!

Thank you, you were clear and to the point.

Straightforward and clean camera view! Thx!!!

I love all of your videos. they're very detailed, easy to follow and well lit. thank you

You should do one for hybrid battery replacement.

This video was super helpful and so easy to follow! Thank you!

Finally someone that knows you should always remove the negative first..!

Thank you! Very clear and good video instructions.

This looks quite easy. Thanks so much for the video!

Quick question, what is the CCA of that battery? Mine just died in my car and I need a new one but don’t know what battery is the correct one to buy. I have a 2010 pruis

Thank you so much for your help My question is if I disconnect battery do I lose m car memory or it would be saved because Prius dose have main battery!?

Sorry to be repetitive, but thank you for the clear video and easy to follow instructions. You've earned my subscribe. Happy New Year! 🎉

To the point. Explains it simple and quick. No stupid music. Thanks

i read you should attach a jump pack to front jump terminals while replacing back battery so you don't lose radio, elec windows and other settings on car ( Like oil change reminder etc

I bought the Toyota Prius 12v battery for $45. I then returned the same battery that the dealer had charged me $210 for, that I had installed. The $45 battery was at interstate battery, they just happened to have one but I don't expect that anyone would find another deal like that. It was the identical, exact same brand and battery that Toyota sells.

Thank you very much for your video very helpfull Thank you again

Thank you for an awesome instructional video. How often should the 12v battery be replaced? I have a 2014 Prius and it’s now 2024 and I’ve never replaced it, am I past due? Thank you.

I had a Prius 12v battery last 12.5 years. Amazing! This video was excellent.

What kind of battery is being used to replace? And where can you buy one? I have a 2012 Prius 2.

I have the stuff on the bar broke. My battery is not recharging. before whole month i left the car is ready to go. Now i have to take battery out every few days and recharge. What gives. What is the one connected into bar? the plastic broke when i took out that metal bar hold the battery

Great what Brand battery is good ? 2015 Prius base
