As usual, I follow in your footsteps. My 2017 Prius Prime now has 132K miles and is 7 years 2 months old. I'd had a new 12v battery for over a year, just hadn't bothered installing it. But a friend who I helped buy a Prime 3 months after I got mine, just had her 12v battery die, so I figured I should not delay any further. I made it more difficult by moving up to a larger Group 47 AGM battery by AC Delco, to get 115 reserve minutes vs the stock 90 minutes. I had bought it for I think $153 delivered from Summit Racing. No return of the old battery required, so I will just sell it to a scrap yard, or take it in to O'Reillys if they still give a gift card for that. It turns them into my free supplier of brake cleaner. I actually think you were smarter to stick with the stock size and the Toyota part, seeing as mine lasted over 7 years, you can't beat that. Regarding my extra reserve capacity, I've never needed it, and when camping bring a LiFePO4 battery to use for that. So my battery "upgrade" mainly costs me extra weight, while giving me little in return. I ditched the plastic battery sleeve, and used a cordless oscillating tool to cut off the front and back of the plastic battery tray, plus cutting the battery-hold-down extensions on the corresponding ends of the battery itself. Then it fit in fine, with very little space left over. The metal hold-down piece stuck up a little more, but still functioned fine. I changed its shape slightly on an anvil, to let it tighten down flush rather than the bolt going through a small gap, but that was not necessary. I made liberal use of the 26 gallon ultra quiet air compressor from Harbor Freight for blowing out dirt, and all the plastic shavings I created cutting the battery tray ends out. Great compressor, often on sale for $350, but I paid $136 for a returned on that was perfect, except the buyer installed one wheel backwards on the axle so it was jammed against the tank and would not roll. Easy fix, and I got it at a steal of a price. I also have the 1 gallon version, which I highly recommend if you want one you can throw in the car and take somewhere. Perfectly fine for airing up tires, and for blowing stuff off, though not for as long before you have to wait for it to refill. The one thing I strongly recommend people do differently from you, is to first remove the negative and stick it inside a leather work glove or something, so it can't touch the battery negative terminal while you are working on the positive, or while you are yanking the battery out. You were able to keep from shorting your tools to the body while working on the positive cable, but just barely, and many people would get into trouble trying that.
You certainly went the extra mile, and it sounds like you learned a few things along the way! I hope the bigger battery lasts longer. And thanks for all the tips. Harbor freights got some decent stuff and is worth looking into. But definitely the negative cable needs to come off first. And put on last!
Thanks so much for providing this video... Saved me tons installing the battery myself vs going to local dealership.. Walmart Auto technician scared me off by saying that I will need to replace that at Toyota dealer and it's gonna cost me 500 bucks out the door because it has electrical components, bla bla bla... Local dealer quote me $350... battery itself now about $199 including tax...
This is great, I also have a 2017 Prius Prime Advanced with the OG battery. I've been jumping it with a portable jumper the last couple days but I need to remove it so that I can get it closer to a wall outlet and use my 12V charger before I totally give up on it and get a new battery. Your instructions for removing the battery are just what I was looking for. Thanks.
Don't wait any longer. Mine suddenly, totally failed, wouldn't accept any charge at all. To move it 20 feet to the street, I had to leave the charger pugged in and have my wife manage the extension cord. Then I could drive her car to buy the replacement battery. Haha, it's ground post was slightly too small, and I had to fashion a copper shim.
@@winfieldhill7643 It's been over a year since I left that comment and my 12V battery is still holding up. I've got a jumper that works, and then I drive the car around for 20-30 minutes and all is good. The worst period has been this past winter when we had sub-zero temperatures and if I didn't use the car for 48 hours it would need a jump. Otherwise, no issues, still using the OG battery.
@@jmwild1 A weak 12v battery can cause so many problems in a Toyota hybrid, that what you are doing is extremely foolish. You'd be smarter to stick a $40 garden tractor battery in it, than what you're doing, though you really should just bite the bullet and say that getting 6 or 7 years out of the original battery was great, and REPLACE IT.
@@EfficientRVer Nope, it's still going strong after over 7 years now. Granted I've also only put 40k miles on the vehicle. Nothing foolish about it, it still holds a charge. When I first had issues with it, both the dealership and my local auto shop said the same thing, the battery was still healthy and the car just can't be allowed to sit for extended periods of time without being started and driven around for 20-30 minutes.
I asked the dealership if they had any discounts and he was nice enough to give me 10% off. It never hurts to ask either. This morning the battery did actually go out. So I got my trickle charger and used it for about 15 minutes and then the car started back up. I then went to go buy the battery and I changed it out today. So it did just go out And I’m lucky I was able to find another battery.
After 7 years my 2017 prius's battery went dead on me after leaving my car sit for 5 days. I was able to jump it back with a portable jumper but ought to just bite the bullet and buy a new one. Looks to be pretty simple.
I am having the same issue with my prius prime 2018, my socket wrench set I bought at the store is not long enough to reach the bracket holding the battery in on the right side. Which set do you use? If you can please link them. Thank you very much.
For anyone in this spot, hook any extensions you have together. Or go to Harbor Freight and for under $10 you'll come out with a set of regular (or better yet, wobble) extensions for all 3 common sizes of ratchets.
Wish I had seen this video sooner as I just had my wife’s battery replaced at the dealer and charged me $198 for labor for the battery was $206… Local auto parts had the battery, but I was a little bit uncertain about using a compatible battery that may not be appropriate for the car Prius prime XLe 2020
I just bought a 2017 a few weeks ago and noticed it had the original battery. After I bought it, of course it died the very next day. It was difficult to find a replacement in my area. Grabbed a diehard from autozone for $200 with 3 year warranty
I was lucky to find one at the dealership for 185 bucks. He told me that he just received a shipment of the batteries. Plus up where I bought the battery from in northern Washington I don’t think they sell too many Prius prime‘s. But in Oregon they sold a lot more so they didn’t have very many batteries.
@@DIYBIGMANdid you have to reset anything afterwards? My mechanic was making it sound very confusing to replace but I've replaced old Toyota cars before. Also, will the warning pop up for replacement or you just knew it was time?
@@DIYBIGMANsorry last question: did Toyota quote you a very expensive price for the battery? Toyota was quoting me $690 just for the battery itself...
When you are loosening, the positive, make sure the socket wrench ratchet does not come in contact with the vehicle body. Otherwise, it would cause Sparks. It would create a short circuit
@@DIYBIGMAN Far better, remove the negative cable from the battery, which connects the entire car to the negative terminal. So that it doesn't flop back and touch the terminal, either stick it inside a leather work glove, or tie it out of the way, or both. Touching the body and the + terminal shorts out the battery, throwing BIG sparks and possibly blowing up the battery if it stays shorted for more than an instant. Especially dangerous because it can weld the tool to the body, and you can't disconnect it then.
Do you really think Toyota engineers are that dumb? OF COURSE it is firmly clamped down, that is what he removed with the 12mm socket. A lip on the bottom perimeter of the battery slips into a mating recess in the tray on the other side, and gets clamped down with the metal bracket held by the 12mm bolt.
If my videos help you, especially this one please consider giving me a thumbs 👍 up. Or a $5 super thanks! That way I could buy myself a cup a coffee!
Just wanted to say TY, replaced my battery today myself for the first time with your help :]
Nice! Glad I could help!
Thank you so much, I need to change mine today. I hope I can find the right battery easily in Northern California
This was so helpful! I’ve never changed a battery before and was able to do it all by myself.

You should remove the black (ground) terminal first. It's safer that way.

My battery finally gave ou luckily t at home after 7yrs. Right before I put the car up for sale..😁👌
Nice! Lol
Thanks! I needed this today!
Nice job on the video, Thanks! Interesting, my "17 PP has the original battery, but, doesn't have that shroud/sheath around the battery.
I wonder if they forgot when they installed it!
Good question but luckily the car is garaged and the engine compartment is pristine
Good move on replacing ur battery before it WENT. 5yrs is pretty good! And being parts are hard to FIND, another job well done! 👍😁

Quick battery swap. Local shop didn’t want to do the battery swap for me.
Because they think it’s in the back above the tire.

Just connect a few extensions together. Use some tape.

It looked like the ODB II port was not used to support/retain the factory settings, the time setting and others.
Mine got a error message. Brake pump failure. Visit dealership. Will it let you start the car despite that?
No idea good luck!

Should be if the battery is in the same area. And looks similar

Is the battery AGM type or just ordinary maintenance free?
Regular battery from dealership.

thanks for the info. Just to shorten the video, it would be nice if you had your sizes figured out
Thats about how long my original battery lasted. Got 5 years out of it.
I thought the 12v battery is on the back!
The previous generation has battery’s in the trunk I believe.
Oddly enough no clamp that holds down the battery. Gravity is the only clamp. Hmmm.
Yeah you’re right I think! Sure makes it easier to change. LOL
I believe that 12mm bolt on the side attached to a steel plate that curved and snug the battery in its place...
The clamp holds the lip on the foot of the battery
