I know this is 7 years late, but my friend thanks you for this video. It just saved him a ton of money on his Prius. His MFD was 'rebooting' and flashing nonstop. Turned out his 12v battery was failing (the display needs over 11.6v to run.) The stealership wanted almost $1600 to replace the battery and the display. This video saved him $1400.
My 2008 Prius 12v battery died after 12 years. Watched your video and got a new battery. Taking it all apart without the proper tools especially the small pink or red plastic cover over the positive terminal was a challenge but got it in the end. Very clear instructions. And bingo it worked. Well done mate.
I have an '08 too Gerry....amazing longevity from the original battery right? So I went and got the same one at the dealership($260) here in Tempe/Mesa and hope it does the same...I'm confident it will-
I folded down my back seats and just threw everything from the trunk area on top of them, and then put my laptop on them, too. Watched this video and used it step by step to replace the battery. Everything went perfectly, very easy. I really appreciate this video. Thank you.
Thanks for making this video for us newbies. I'd planned to replace the original 12V battery on my 2005 Prius today, but first needed to find out where it was. My Prius has 286K miles on it and I have never had a problem with it. It may not travel at the speed of light, but I look at it as 8 years without a car payment. Love this car and will buy another one someday (hopefully not too soon).
286k!!! That’s incredible 😍
10/10 THIS WAS INCREDIBLY HELPFUL. My 12v battery in the back of my 2005 Prius died on me and they were quoting me over $1000 for the service in this video. Obviously it took more than 6 minutes for me and my husband to do it but this video is what got us through! THANK YOU SO MUCH! I’m so grateful! My car turned on after the second time turning it on like he said at the end! Thank you!!!!!
If a repair shop told me they want 1000 dollars for changing a freaking 12v battery, then I'd make a note for the future to never come within 5 kilometers near that place, because that's a level of scam that I haven't seen before.
@@ThinBear4I got quoted $500 +tax and I wasn’t doing it 😂
Got told 356 for just the battery. Labour probably 200
What a comprehensive tutorial. Not a single step missed! Even puts the carpet back at the end.
I got addicted to Eric about two months ago. Watched all of the recent videos (i.e. Jeep hat era) and am now digging through the archives. Old school Eric was much more serious than new school -- but, as the end of this vid shows, the sarcastic star was always in him!
"Remember folks, if I can do it, you can too" I stumbled across this after having watched your channel for about 5 years. Someday you should do a recap of the early years.
LOL it's great seeing your progression throughout your videos... here you were SO STIFF! Now you are the cool, laid back guy everyone wants to be pals with.
Love finding a SMA Video when I need it. Eric was so serious back then.... sounds like a German auto mechanic
I actually came to this video to see how to remove the red plastic part that covers the positive terminal as another video didn't have it. Thanks for showing how to remove it safely.
Auxiliary battery went belly up and your video really helped with doing the install. Back to the strip now for quarter mile passes in the high 17's. LoL
lol
What sort of mods did you do to make it so fast?? Is a neck brace required for safety?
This video is still helpful today for the diy crew! Thank you so much. We were able to watch and follow with ease. Well 45 mins it took because we didn’t have a longer extension to use so it would have taken less time.
Thanks for making this video! It's the only I could find that shows all the steps concisely without relying heavily on staging (which tends to hide all the detail I need to make sure I don't screw something up).
Thanks again!
Wow so much has changed. You're much more camera friendly now a days. I Sincerely enjoy watching your channel almost daily.
So I fixed my car! Water intrusion had wiped out the 12v battery. I've ended up cutting away the interior soft furnishings over the battery as they were almost rotten. At 16 years old it really doesn't matter what it looks like! Once dry I can fix it back in and the felt can be replaced easily if it is smelly or too rotten . I could see exactly the pathway the water had taken and it had obviously been leaking for a while as there is a tide mark 2" up the battery well. I've used heavy duty outdoor builder's sealant in the cracks I found around the hatch - thanks to some other RUclipsrs for a heads up on their common location! With the soft furnishings out of the way I can see if I've fixed the leak - won't be long - Manchester UK = biblical rain on a regular basis 🙄 It was not an easy job to change the battery but I refused to be beaten by the awkwardness of it's positioning! I can make a wedding dress so I can surely tackle this! Anyway, took it for a spin around and was slightly worried at first - the hybrid battery started at full blue but then dropped to the last blue before it goes red so I headed for our motorway ring road and as I'd hoped I soon got the green lights which stayed for most of the rest of my journey! I think it is safe to say that the hybrid battery is perfectly healthy and the central locking which had failed completely just started back up again! It really is one awesome car! We'd decided to downsize but maybe not just yet 😆 A massive thank you to all the wonderful people who share their skills and help us to be self sufficient in looking after our aged cars and save the environment from all the scrap and the emissions generated by the building of new cars - you are truly awesome!
a Blast from the Past,...Not so much of a talker in the older SMA videos but straight to the point..job accomplished !
Thank You So Much! Easier than Most Mechanics will Tell you!
Thank you...your video made my swap out of the 12v battery on my 05 prius easy. I had an 84 month battery in it...it lasted 106 months. Bought the correct 12v battery on amazon and replaced in 30 minutes.
What is the battery brand and make? Amazon link please?
Love it or hate it the Prius is a successful design. On a trip to Berlin I was picked up by a Prius taxi and sitting in back asked the driver what he thought of it. He had been a taxi driver for over twenty years and had been a big fan of Mercedes until they ‘started building crap’. He said that although the Prius was a complicated hybrid design it had been 100% reliable and was economical and for a self employed taxi driver the Prius left more money in his pocket than the Mercedes ever did.
Thanks for the great video, so easy to follow. You took all the guesswork and anxiety out of the process of my changing the 12v battery in my 2005 Prius. My only downside was discovering a 1/2 inch of water in the well under the battery platform. Scary, I don''t know how it got there but will have to solve that riddle.
A huge thank you for your tutorial video. Hope you and your Prius are well.
The shy ERic O :D haha.. funny to watch the older videos :D
I've been watching you for years. Great video and I like the way you are doing them now too. Thanks. I think I have a leak somewhere... rust at the bottom of my battery tray.
excellent commentary Eric. Perfect placement of silent regions
Great instruction video. I had just replaced the 12 volt battery of my Prius 2 - 2005 with succes. Thanks
Thanks mam. I just replaced my prius 2008 battery using your video.
Holy, your vids have come a long way since this one was made. Enjoy them all though, old or new!
Wow, good information but what a difference from his newer videos.
I was expecting to see you rebuild the main battery!!! Take care. Doug
Jesus, the battery in this car is secured better than a vault in a Fort Knox. Good thing removing it doesn't require entering nuclear launch codes and turning two keys simultaneously at the opposite ends of the car. What a horrible design.
Thanks for the tutorial. God knows we need it.
Them were some pretty good Bumper Stickers
Thank you so much for this video. Saved me so much time. You’re the man.
A++ Complete in proper sequences some others missed
Good going on getting the message out for neuter spay your pets!
And also like the video, is very informative and easy like me myself could do.
G'day, Mr. O! You cracked me up, with the ending! By the way, the recent genetic 'hybrid' of a dog and a mirror has given geneticists pause for reflection.
Cheers! :-)
I had the battery in my '96 Dodge Ram replaced at Sears. I notice they attach a small motorcycle battery before disconnecting the main battery so the computer doesn't lose memory. I know when my battery got really low, the computer would lose memory and it would shift funny or stall when coming to a stop. After a few miles, the computer would re-learn it's parameters and the truck would run fine.
Replaced my original battery today after 207k miles and 11 years 8 months since I bought my 2005 in April 2005
how much is it?
$500ish
Great cars. I used to own a 2013 Prius package #5. Highway rated 48 miles per gallon. Max I ever got was 45 miles per gallon.
Reason I got rid of it was due to the snow. It got stuck everywhere. Other than that it was great packing, GPM, exc.
Step 1: take the entire car apart…😂
Great video though! At least I know what I’m getting myself into.
Who else was thinking "dang 6 min video to do a Prius battery!" only to find out it wasn't the hybrid battery LOL!
Jeff Jeffrey me
12 volts was a great big clue.
I own a 2nd generation Prius and it was obvious that the guy was referencing a 12 volt starter battery NOT the expensive lithium ion battery.
My friends' Prius had "water intrusion" down the hatch, drained into & *FILLED* the battery compartment in 5" of block ice. Shop had to (under my suggestion) pour washer fluid on ice, and park a salamander near by. After chipping & poking around it 1 hour- got the *frozen dead* factory battery out.
I then drilled a 1/4" drain hole underneath the battery compartment- at the "lowest" spot. Never had that problem again.
"Water intrusion from hatch" is a *known inherent problem* that Toyota refuses to address.
Wow never heard of that problem
it comes from the sealer used on the body seams drying out and cracking..
Thanks, good to know it wasn't just me. I had a pool of water up to the bottom of the battery when I got the old one out. Was hoping it wasn't acid that had leaked out, but was too much for that. Was thinking that of making a drain hole too. Either that or fill it all the way up and raising koi.
Me too! Trying to trace the leak before I put the new battery in. No ice though, just water. Biblical rain in the UK for weeks with the odd heatwave thrown in for good measure 🙄
There's already a drain hole built in, you just need to remove the grommet, I started getting spiders in mine though.
I did both! Like and previously adopted a dog named Captain Biscuit. She's great!
Constantly being reminded that modern cars are not just different from cars of my day, but from cars of just 10-15 years ago. They just don't build them like they used to. Mostly that's a good thing, but somehow I'd rather have a 10-15 year old car to work on. I live in the deep south of Pennsylvania so there are more of them surviving down here.
Eric, your vids are great! Sub'd and liking all of them so far. You are providing a real service to the DIY community. Thanks so much! Done a hub assembly on one of theses yet? I'm a fellow rust belt wrencher from Minnesota and know these get stuck bad!
+Ryan Wojack O I have done one or two on the these cars. We don't see a lot of them here
I used to laugh at them cars. Till you see LA traffic and then you see the logic.
The torque is crazy. You can easily peel out in a Prius. Most of us choose not to.
Bro, as someone who got a 2006 prius in the fall, so many cars I get into feel inferior to the mighty prius ever since, at first I was just glad it was fuel efficient but now there's so many little things about the prius I appreciate so much. I hated the push to start at first, now I love it, the ability to unlock without pressing a button blew my mind. Idk the prius is a great car and I didn't understand it until I owned one.
hi Eric, stumbled upon your channel not long ago and have subscribed. enjoyning your channel in my shop as i enjoy my cigar and whikey during these cold months in Canada,,montreal to be exact. you have good content. keep it up.
crazy places for batteries to be. i guess for such an easy job these motor companies figure lets put labor into it so diy yourselfer would take it to dealers so the can make money. think about the difficulties trying to boost your car in these cold climates.. would never purchase such a car unless it is located under the hood. keep well
As others have said, you are so much more natural now doing your videos, the old ones you were very stiff/matter of fact only.
Thank you so much sir! Very helpful video.
This was helpful, thank you!
You will also need to do this if you have a {very helpful autoparts retail store} read your OBD codes & then you fix something. They generally will not clear the codes. Disconnecting the 12V for a moment lets you reset that computer (separate from the MFD computer) and prove whether you've actually fixed something or need to start buying parts. This battery dance or borrow/buy a $40 code reader one time & become the neighbor who shares it out. After taking the whole trunk apart a few times, that $40 scanner starts to feel like a great idea.
Irresistable urge to do some recycling! LMAO
I'll take a pre 90s vehicle any day. Pre 90s where life was simple lol.
Wow early prehistoric SMAC video
Thanks! Just had to do this job this morning.
a thumbs up or adopt a dog ha! Love it! Thanks for the perfectly illustrated video.
Glad you liked it!
It would be helpful to know what tools you used, the sizes of the sockets, etc. great video.
12mm and 10mm sockets
As a related fun video, you could show how to open the rear hatch when the 12V battery is dead. It involves removing everything from the hatch area, the floor, and pulling a latch behind a little panel. Ask me how I know :)
thanks man for your positive message about adopting a pet and stuff, I love animals too...the extension attached to your drill, what size is it? thank you!
What are those fusible link connectors for? I busted the smaller of the 2 and I was wondering what it's for.
LOL!! Take a break and recycle something, adopt a pet or go hug a tree! Gotta love those Prius drivers! They are definitely something else. And don't forget to tip the valet...
I recently took over an old 2007 Prius so this is perfect video for me. I know this has been an older video, but I hope I can still get a reply. Is there anything need to be done with the onborad computer or ECU (I think this what it is called) after replacing the battery?
thanks helped a lot. you forgot to put the red positive cover back on.
Still watchin OG Eric O in 2020 😆
Eric....thanks....does the engine starter use the battery you replace or does it use the larger battery pack...?.....thanks again...bob
Thanks for the awesome video! My only question is when i reinstall the battery vent does it need to sit flush to the little vent above the 12v battery or does it kind of hang there? i reinstalled the bolt but it doesn't seem to snap into place or anything like that. Thank you!
Thanks Eric! Greatly appreciate the help.
Always disconnect the negative battery cable first and reconnect it last that way you don't have any sparking since any vapors from the battery can be explosive.
Thats what he did
That is not the reason for "... disconnecting negative first/connecting negative last..." as there is virtually guaranteed to be a spark at the terminal. The reason is to avoid spark resulting from touching body ground while tightening the positive with negative/ground already connected.
Love the sarcasm : "Start this hot rod". Plus the typical bumper sticker vehicle. LOL! Wait till they put V8 sounds coming out of the speakers when you push that Start button! Who's gonna be laughing then… LOL!
Lol couldn't help it... these Prius people are usually a pretty unique bunch to say the least... now go adopt a dog a man!
Thank you!
Hi. U.K here, Only question I have is that you did not put anything on the Battery Terminals and Clamps? A lot of people use Vaseline or GP grease, I actually put on Copper Grease as I picked up a big tin for the price of a tube when I changed my Brake Pads on my car a couple of years ago?
+ANDREW CULLEN Because it didn't have a corrosion problem and these cars typically don't
Well it tool till the end of the video before the wittiness came out 🤣🤣🤣👍👍👍
I HATE PRIUS'S ! ! Thank God for the shop owner Caroline on iATN who bailed me out more than once!
Working on accident Prius's is whole different subject! ! !
@@mikechiodetti6737 Clarify this comment if you would be so kind?..
One thing that was skipped was the vent tube. There's a little tube that you have to pop out of the original battery and into the next battery so you don't get fumes in your car from the battery
The ending got me 🤣
what if the vent tube falls into the hole on a 2010 prius aux battery? can i fish it out or go underneath car
Thank you that was very useful
What is the function of that black box next to the battery? I heard you say somthing about the brakes..
Thanks for your value video.
Pretty nice not having to remove a dumpster-full of garbage from the trunk before working on it.
Thanks brother. And I adopted a dog. Lol
Good tutorial except taking the red plastic shield on top of the battery. It has three tabs which secure it. I broke off the top one and then decided I just take off the 12v pos cable and it all comes off after removing tab which secures it on the hold down. Its a secure idea which needs improvement in my opinion in my 40 years as a mechanic.
Can anyone tell me what size sockets he is using? Much appreciated 🙌🏻
Thank you for spending the time to put this video together. Would you know if this procedure is similar to what you would have to do for the 2007 prius? Also, I have been told by shops that reprogramming is needed following the replacement of the battery, is such a procedure completely necessary?
Thank you for sharing.
I didn't even know that they had a 12v battery❗😏
Hi! Is it also possible to mount the new Agm/gel sealed battery? They don't have the hole for vent tube because are completely sealed. Thanks for your answer.
They have them today with the vent hole. I just bought one at Autozone AGM YellowTop Specified with smart key specs so you have more amps than non-smartkey version.
ROFL. Oh Boy! You've come a long way. More dog tricks Please. lol
LOL Hey Eric... I never seen you so happy to work on a car (if that is what the THING really is) Just made me laugh
Grazie mi hai salvato
um... Did we "forget" to re-install the hold-down clamp? Like I always do?
Great job
I like Toyota's but geezus that's a mission!
Thank You so much!
need a 12 volt battery for a 2004 toyota prius. Could I just buy a barrery from walmart that fits?
My battery vent doesn't click in I can't push it all the way in? Any suggestions?
6:06 "I gotta gopher now"... I see what you did there.
Nice job.
Haha, loved the vid.
Thanks!
