Gen4 Toyota Prius 12-Volt battery change for new one

Generation 4 (currently 2016 through 2022 model years) starting/starter battery replacement. My car would not start, it is under three years old and the original battery died in the summer heat yesterday. Luckily I had a "Jump Starter" that I had bought recently (and charged up at home) with me - that's called *being prepared*, and it saved my ass.

Love the explanation. Anyone with zero experience can do it (with your help)

[@Spearfisher1970]

Very kind of you. I'm just here to help where I can.

[@leatinney7694]

I’m 65 yrs old haven’t change a battery in decades. This video was very helpful and ta da changed in less than 30 mins and it works.

[@Spearfisher1970]

Happy to be of service.

[@trombonecontroller]

Helpful, thanks. I couldn’t remember which terminal to do first so I appreciate that you mentioned that, as well as the specific hex nut size.

[@jdellapepa]

This was very helpful when I changed my battery today. Thanks!

[@seanwong2495]

Thank u for very simple n straight-to-the-point presentation on this battery replacement. This helped me a lot cause I had thought that a battery replacement for a hybrid would b more technical. I noticed u didn't even need to wear rubber gloves for this procedure. Thanks again!

[@alanabaker2441]

Your video was PERFECT! Thank you so much! Got installed in no time!

[@ghrnandz01]

Thanks, made it all simple, having this review of process and specifics of locating everything!

[@philipwagner7929]

Thanks ! What a relief. I was afraid I would have to tow the car to a dealer for a computer reset. I am storing my son's car, and I don't drive it enough, so the original battery went completely dead and now won't take a charge. Whew !

[@susanmoracha7102]

I gotta give you big time kudos for this video. like the prior comment it's been centuries since I had to change a battery and obviously cars are way more complicated, even something as simple as this battery replacement did require a different approach then back in the day. Thanks bud for sharing, take care 🙂

[@nellylepe]

Thank you sir. Thanks to you, I a woman in her 30’s, was able to do it all on my own 🙌🏼

[@DavidThomas-sv1tk]

No reason any woman can't do any auto repair. If someone uses their penis to replace a 30-pound battery, they're doing it wrong.

[@daveh5625]

Thank you... i will do my 2016 before end of 2022. Dave AZ

[@mcminegar]

This was really helpful. Thanks for the guidance!

[@-.-_123]

Thank you so much!! I was able to do it myself thanks to this video.👍👍

[@Spearfisher1970]

You are so welcome. I hope it wasn't too long or boring.

[@neilwoller]

Thank you for this video. It was very helpful & very well explained.

[@Patrick-888]

Thank for telling us the battery you used to replace the toyota battery and where you got it. My dealership, miracle toyota wants to charge me $300 to change the battery. They also wanted to charge me $914 for 3 tires and a 4th for free. I went to Discount Tire and got 4 tires for $581. They are awesoe tires and so much quieter

[@Spearfisher1970]

O'Reilly Auto Parts is where I got the battery. What brand and model of tire did they get you? Keep in mind that new tires (of the same type, not touring vs. mudding tires) are just about always quieter - you really can't start to judge the road noise until about 15k to 20k miles, and then-after.

[@Dimo151]

Very helpful, thanks

[@ericmonte2038]

Really enjoyed the video. I was just wondering what is the best brand to buy for the car battery and I'm assuming you can get it at a retail car parts store. Please let me know when you get a chance. Thanks!

[@Bbbuddy]

To help with the hood latch, oil it and unscrew the rubber bumpers at the front hood corners 1/2 turn. This will put a little tension on the latch. Don’t raise them so much that the hood doesn’t sit flush. Looks like yours is a little high already. Perhaps you hit a curb and tweaked the latch strut. It’s diabolically connected directly to front lower radiator support, and transmits any deformation there to the hood.

[@Spearfisher1970]

I bet you're correct. Thank you!

[@Video1Unit]

The video is is a bit basic for me, but it was helpful to know socket sizes in advance. This really sped up the installation process. It took me less then 10 minutes and that's with cleaning out the battery tray of loose dirt. Thanks. 2020 Prius here.

[@drjulieh]

I appreciate this video and that you tried to keep the camera on things as you went - I know it's hard to work with one hand. Thanks! No other concerns within the computer system? I'm always leery since it has the hybrid battery in it if we have to do something else or reset anything else

[@Spearfisher1970]

No, thankfully no concerns. Toyota kept this end of the electrical system / 12V system simple.

[@faithr719]

my 2012 prius I drove it 10 years and 345,000 miles never replaced the 12 volt battery.

[@udance4ever]

read reports that sometimes the 12V battery needs replacing after 4-5 years so good to know u got full use out of it!

[@dmarinon]

why that water on the battery??

[@AntonioCAM925]

Can i use this battery for any other car?

[@rajkallu610]

Super

[@dansu92833]

Would H5 fits that Prius?

[@stevefreier2156]

Isn't the Prius 12 volt battery supposed to be an AGM type? Not a Lead Acid.

[@udance4ever]

​​@jonny_lagunawhy is an AGM recommended? what is the difference?

[@nguyenvinhvx]

Thanks for the video. It seems to reset the car once the battery is out, right? Clock, settings, preferences had to be redone.

[@udance4ever]

what are the techniques to preserve all the settings? I particularly don't want to lose the history of mileage by date in the trip diary.

[@nguyenvinhvx]

@@udance4ever There is none, I changed mine out recently and the only thing that was reset was the clock, everything else worked, wireless keys, settings, bluetooth, everything was the same.

[@Spearfisher1970]

@@nguyenvinhvx Same. I did not lose any data in the diary, but then I use Fuelly app for all my data anyway.

[@DancerGirl-24]

does not look the 12v battery pack which is in the back of the 2017, not hood front. but maybe a mechanic-like understanding might still work to change the 2017 prius v battery.

[@frankquinol]

Does the computer or anything in the Prius need to be “reset” after installing a new 12 volt battery? I heard if you don’t reset the computer the car would read that it’s still an old battery connected and won’t start the engine. Ever heard of such a thing?

[@Spearfisher1970]

I have heard of this issue with other machines or devices (not even sure they were vehicles), but not on Priuses for a battery that recently died. In the case of this video, and most cases of weak batteries - as well as the stranded motorist whose truck I jump started (not with my Prius) two evenings ago - the batteries still had enough charge to turn lights on, etc., but could not turn over the engines. That may all change if you put a Prius into a secluded storage for a year or more and completely drained/killed the 12V battery, but that would be an uncommon occurrence.

[@user-kq1ox5wy8s]

When I called Toyota to change the battery they are charging 175$ just to install a new battery and saying it costs that much because they need to reset the codes on a hybrid car. Is it true or they just making things up to charge?

[@riceburner4747]

Not sure if anyone answered u, but I went to Toyota parts dept, & installed mine in the parking lot. I gave them my old one for a core charge. All the computer does is go by age of battery & let u know when something is wrong. Being I worked for a battery company years ago, there is no issue with me bc I'm constantly checking mine.

[@forw4rdp422]

What about the starter battery (the one in the back)?

[@riceburner4747]

If u have a new/good 12v, ur traction battery doesnt have to work so hard. The more u drive, the better.

[@forw4rdp422]

My issue is starting the car. The car will run for however long but the actual starting. Not sure because the battery hasn’t been tested yet

[@udance4ever]

​​@@forw4rdp422if you have an older Prius, you are correct, your 12V is in the back (not under the hood like the 2019 featured in the video)

[@riceburner4747]

How many miles did/ do u have? I, too, have a 2019. I'm surprised u needed one, may have sat on car lot for a while. During pandemic, our cars sat home more, especially during winter here in rust belt. That, too, what part of country do u reside? I'm an old battery man, I slow chgd MY battery 1st thing in the Spring this yr. One more, I slow chg all my new batteries to get them off to a good start before installing. And chek the DATES on ur new battery to get the freshest u CAN. U got a sub'd & a 👍!

[@udance4ever]

in the video it says 44765 on his odometer. I had my 2019 battery go low on me & did some research & it is possible a 12V battery may need replacing in the 4-5 year timeframe. that said, the dealer said the battery checks out fine & didn't need to be replaced so just gonna keep rolling with it & keep a jumpstarter under the seat.
