Great Step- by- step video. To remove the battery, you are supposed to remove the negative cable 1st and then positive. To install, you reverse the order - positive cable 1st, then negative.
I can’t thank you enough for making this video. The battery in my Prius C just died, and I figured I would have to take it to an auto shop because I didn’t want to mess with the battery in its funky location. But your video gave me the confidence to realize I really could do it myself and save a chunk of money at the same time. Well done!
Thanks for the sanity check, I appreciate this video! One thing I discovered before watching this video, at least for my prius c 2013: You can take a screwdriver and can press the center of the clips, like a button, and the clips will actually disengage and pop out with very little force required.
This was a very helpful tip. However, I had a follow up question: how do you get the clips back in? Part of it is flared, making it difficult to insert into the hole once again and secure the panel. I've got all the work done except for that.
Not going to help now, but maybe someone else. Remove the plastic middle core and then insert into the hole and then push the core back in to flare the clip and secure the panel.
I cant thank you enough for this video. I have a prius 2012 type c and i have no experience with fixing cars. Your video have saved my mental peace and has taught me everything my dad didnt. I cant stress enough how much i needed this video. Once again thank you!
Thank you for making this detailed video, with very clear video. It is by far the best I've seen on RUclips. It is better to remove the negative terminal first, in case the first loosened terminal flops around and contacts other grounded metal nearby, before you can disconnect the 2nd terminal. When reconnecting, the positive terminal should be connected first, so if the second terminal flops around and contacts grounded metal nearby before you can connect it, it won't arc.
Good job! What a tight squeeze that was. You're like me. I'm a firm believer in preventative maintenance. I have a 1989 Dodge van with approximately 550,000 miles on the engine. The engine was only opened twice. As a maintenance, I had the timing chain replaced at 210,000 miles, and I personally did it the second time at 500,000 miles. It runs really tight and when I hit the gas it still wants to rip the wheels off. I change the oil religiously at 3000 miles or less depending on conditions. I use Marvel Mystery Oil in the fuel and in the crank. I put it in the fuel at every fill up and in the oil at every change. I had a lifter tic in the morning (especially in the winter) for over ten years. I tried everything short of going into the engine to fix it. It would always go away in about 5 - 10 minutes. I was never made aware that this 318 cubic inch engine required oil with ZINC in it until a very knowledgeable worker at O'Reilly's told me about the zinc. I replaced the oil with one with zinc in it. It worked but not very well. Then he told me to buy a small bottle of straight zinc. I used some and improved more. Then I put the whole bottle in and the tic stopped completely. I used to get 17 mpg hwy and 12 city. about 8 years ago it dropped to 10 - 12 mpg hwy and 10 mpg city. I tried everything but the mpg would not budge. The same guy at O'Reilly's suggested a different spark plug. I put in the new plugs and took a 1,000 mile round trip from Oregon to N. Idaho. I did a very accurate test by carrying regular fuel and completely runing the van out of fuel. I got 16.2 mpg on the way up to Idaho. I had the fuel filter replace right after the test. I got the same mpg on the trip home. No matter what I did to improve the gas mileage over the years, i could never get better than 17 mpg. Now after installing the new type of plug, i get one mile less than the steady 17 mpg I got for a couple of decades. The difference in the new plug is that the tip of the electrode is slightly concave causing it to have more surface area. Now the engine starts faster, has no tic, and gets 16 mpg. The rest of the van is beat but it runs great.
Dude...I appreciate your trying to help people but be careful. Removing the positive terminal first (on a negative ground system) can be super dangerous. You are running the risk of your tooling shorting your positive directly to ground if you contact structure. Lucky for you Toyota has foreseen the likelihood of this and isolated the bottom seat frame in this location with a plastic shroud. Negative off first on last in this case, minimizing the possibility of a tooling short. Again good on you for trying to help people, just understand the risk here.
@@brianmef71 But a 12v car battery can deliver 100s of Amps. Very dangerous if a wrench loosening the positive terminal touches anything grounded, causing a short circuit. See ruclips.net/video/ZfFViY1-zYw/видео.html Of course the hybrid battery is way worse.
He really should update the description on the video to note this or even update the video with inbetween edit to note this correction ... people aren't going to read the comments on mobile when they work on their cars.
My 2017 Prius C has the battery located under the backseat on as in your video. Unfortunately the seat isn't designed to pop out as a 2013 Prius I used to have, so it is tight in that area under there. But seeing this video has helped me understand how I can get the old battery out and install a new one,! However, as some of the other comments I read, I believe it is very important to disconnect and reconnect the terminal connections in the correct order as the manual states. Nevertheless, thank you for posting this video! 😃👍
I came in here because I want to help someone who has the same problem as mine. Just recently my 2008 Prius went completely dead even after changing to a new battery. There was no life, nothing at all. I had to ask my friends to give me a jump. After watching many RUclips videos I found out that one of my fuse was gone. When you open the fuse box, at the right under C section, there are two blue no.15 fuses. I changed the second one from the top. After that I also had to tighten up my negative volt battery which is in the trunk attached to the back of the car. Make sure you unscrew the negative volt before putting on the new fuse. After that it came to life. Hope it helps someone.
One mistake, I believe. Always remove the negative post of the battery first, and replace last. This is because if you touch (or drop) something that touches metal between metal of car and post of battery negative nothing gets shorted....and once negative is removed the positive post can't short
great video, thanks! I got the same car but is now having issues starting. Dashboard is dead except the engine light. Tested and the 12V gave a strong 12.65V off-load. Any other things I should check please?
Thanks! Hmm, starting issues are a pain in the butt. I'd start with the fuses, main relay or alternator. Also, Prius's are very sensitive to oil levels. Don't overfill!
The little button in the center that you pushed in to get the clips out needs to be pushed outward. Then, once the clip is in, you push the center button back to its original position.
I’m trying to remove the positive read on top of the battery and I’m having a hard time. How did you do it? Because they’re still another screw holding it in place with red plastic
Thanks for the video. Is there anyway to check and diagnose the 12V battery before changing? I think pruis car has this function on the dashboard but i cant seem to get it.
This battery is out stock everywhere I go!, Finally I went to the dealer and it's coming in two weeks ($260 interestate battery), in the mean time I on a mission to find a replacement!!! Any help is welcome!!! Another youtuber said Battery from a normal Prius will work just fine....
Wow this is surprising! When I was at Toyota, they said that is was the last battery they had for the Prius C model on the dealer. Luckily, I was able to snag one. Keep us posted if you were able to source a replacement! We are all curious here, good luck! I wouldn't trust other batteries working on the Prius C unless it's been tested. Better to get OEM or OE replacement.
@@Echizen32kMedia because i had decide to buy prius c . i went to one used car company , and the saleman told , once u change 12vbattery, it will show error code . so curious . maybe the salesman knew that hybrid battery getting issue .

My prius c 2012 still have the original battery. What is the symptoms if it starts to fail because the 12v battery doesn't start the car. Also if I disconnect the 12v battery will the check engine come on after I install a new one?
No, you shouldn't get a CEL if you disconnect the 12V battery. I guess common symptoms are weak starts or electronics cutting in and out. Worst comes to worst, you won't be able to start the car.
I know this is an old post, but just in case anyone is still interested: My 2012 Prius c just had its 12v battery die today. There were no warning symptoms. I went to the grocery store, and when I came out and tried to start the car, the battery wasn't providing enough juice for it to even try. The interior lights were on very dim, and the brake pump that usually kicks on when you open the driver's door was making pitiful noises. And then the whole car suddenly smelled very strongly of sulphur. That's when I knew: the battery had a catastrophic failure and vented. So, if your battery is ten years old and hasn't failed yet, you may want to consider preemptively replacing it.
I've got the same 2013 Prius C Trim level 2 and my battery is under the back seat as shown in the video. I think both the regular Prius and the Prius V have batteries in the engine compartment.

Thx bro! I easily replaced my battery today thanks to you! My car went 120k miles before I had to replace it for the first time!
Nice! Did you get a check engine light by any chance? Or just replaced it on a whim.
I did get a check engine light. It was the first time I’ve seen it in a 120k miles and then the battery died shortly after it came on!
Thanks for this. The battery is in a hateful location (unlike old Volksies you can't just lift the seat up) but the video gave me just what I needed.

In the video you said remove positive and then negative. In the description you said remove the negative then positive. Now what shall I do
Negative first....In comments someone said the manual confirms that you do the Negative first.
Ours is a 2016 Prius 3 and the battery is under the hood.
What is that little black hose?
Some kind of breather tube I think.
It vents gasses from the battery to outside of the car because the battery is inside the car, unlike most vehicles.
You could lift the seat up for more room
thanks for this! but you skipped the hardest part, which is putting those %$#@*!! black buttons back into the seat cover! 😆
Thanks man! Yeah, putting it back is a pain in the ass.
