but it IS a mission? watching the vid and reading comments like yours underprepared me for this job tbh... from the vid it seems like you can do the whole job in the car. now i find out i would have to remove it, and should have just removed it and made it easier to begin with... and just more steps/stuff than I really set aside time for...ugh! /end rant
@@bestmantoday I think the 8mm bolts on the bottom need to come out before the 12mm end bolts. As soon as the 12s are removed, the pack will expand and the 8s will move and binde. And, just thinking about the future; why bother putting the 8mm bolts back in? What do they do besides nothing? The 12s and the retaining rods hold the pack together.
Thank you, thank you. I was ready to scrap my 2008 Prius due to the battery alerts. Your clear instructions helped me get the ONE cell that was bad out and have a Prius that runs like new!!!
@@gregkampoz8009 yea it's a very sensitive system and one or two cells That's why I've been trying to do the research on how to replace just a few cells myself when I'm not an electrician nor a mechanic instead of paying over $1,000 to replace every cell in the battery
Maybe the BEST RU-vid video I’ve ever watched. Straight and to the point but still very detailed, no mumbling/chit-chatting, and no shaking/out of focus camera. Well done! I’ll be referring back to this video as I change out a cell or two in mine this next week. Thank you!
Wow, excellent mission accomplished in a simple way. That's what I have been looking for. Hybrid battery fix and is as simple as this one and all other videos scare you to death when dealing with hybrid battery. It's the common sense that one needs to have rather than putting safety gloves like they shown on other videos. Thanks for making it so simple.
I'm working on this now. This video leaves out waaaay too much. My recommendation to everyone, don't use this as your only reference or you will be highly frustrated. One important piece is that the entire battery casing needs to be removed from the car and elevated to get to the 8mm bolts on the bottom. And it's at least 100 pounds. I recommend having a workbench and a helper. Also, have little sandwich bags and labels ready for the many bolts to keep track of.
I was just looking at your thread on Priuschat, really inspiring man. I don't want to be quite as extreme but it's nice to see how good a gen2 can look.
this video is by far the best prius hybrid battery service, would be wise to just clean those copper and the fan motor while at it. great video. dont write comments on video but this A+.
I know I am late to the party. But let me raise three questions. 1) A major source of showing weak block is the bus-bars being corroded and oxidized. I was surprised they were not cleaned. 2) Did I miss something? You can’t remove the the blocks in-situ ( in place) without unscrewing each block from the bottom of the chassis (@3:36).That can’t be done, without removing the whole battery pack and getting access to those screws. So how was that achieved? @4:46 you show the battery pack in the tire-well. That means you removed the battery pack out, the most labor intensive part of the exercise. But you skipped that step. 3) Why will you call a DVM a scanner? Confuses the heck of noobies. 4) I wish you had specified which generation Prius it is. The cell number ( actually they are known as blades) is from right to left in Gen 2, and left to right in Gen 3. Regardless of the generation, look at the black ground wire for the high voltage, it always goes to the negative terminal of module 1. Update: looking at the Soleus Scanner results, the car is a 2004, Gen 2.
The batteries bloat when they are charged. You need to keep them in their compression pack or make your own with clamps/wood. Also, when replacing “blocks” you should recondition, balance the entire pack. Good luck homie!
If I was to do what he did and just plop a few new cells in do you think the car would actually run and the lights will go away on the dash? Cause I'm just tryna sell my car and can't if the light stays on I haven't put in my new 4 cells in cause I've been considering reconditioning them but it seems like a lot of work reconditioning the whole battery and I'm not very smart with all that.
@@danielarmstrong3487 That will work if you can find out which cells are the lowest ones. I use the both the Dr Prius and have hacked TechStream on my laptop. Once you see which block(s) are low, you can replace them. That should hold you over for several months. After replacing the new cell/block, I would put it back together and let it sit for 24 hours so they can balance out within the pack. On a sketchy note, if you just want to clear the code/light ...get the correct dongle and buy the dr Prius app on an Android device, you can simply go in and clear the 'check hybrid' code. It should run a day or two so without throwing the code again and illuminating the warning lights. Thats being a sketchy seller tho. haha but....its you note so....FYI ha
Can you also swap around the cells on the outside of each side to the inside since they tend to read a bit higher on capacity, moving the slightly weaker ones to the outsides, with the chance that it might prolong the life of the hybrid battery overall?
Thank you so much, this video is going to save me $1,000+ when my 2006 battery starts to die Question- is there anywhere that you can touch that you could accidentally get electrocuted? I want to be extra safe and make sure I don't get shocked, that's my biggest concern when dealing with the hybrid battery
just make sure the postive and negative terminals DONT TOUCH each other while in the case and the battery pack is in the car and you are doing what he is doing,..if the terminals do touch ea h other , pass my love to michael jackson.
Tried this myself. Was an insane experience considering I’ve never done a job that intricate before. After replacing the bad cell. My car won’t start. It’ll just turn on but engine won’t go. I’m assuming I might’ve done something wrong? Or do I have to jump the Prius in order to get the juice flowing. Any advice would be greatly appreciated!
while i would imagine the general approach is the same regardless of model year, what year are you working on and are you aware of any modest changes across prius gens to watch out for? I've got gen 2, 3 and 4 - thanks, brian
I notices you are counting cell 1 at the fan (right/passenger) side. I have seen another video where they count cell 1 at the module/left side. So, cell 1 is at the opposite side of the module/ecu - correct?
Awesome video! Hey if I don't care about shuffling them is it possible to just loosen the end cap and the bottom bolt of one cell and just slip it out and a replacement back in?
Thanks for the video, this mission is something I need to do soon. I see you use a sensor to check the battery, what device is that? I see you have a display system for checking the codes on the prius computer for the battery issue. What device is that? I've never worked on my prius before and now the battery is not holding a charge/the car is not starting up consistently. It would be great if I could do this operation myself and not pay hundreds of dollars for a mechanic to do it. Thanks for the guidance.
It was a great video next time where some protection 8 w done them tons of times u actually beat my time 4 minutes good work are you still working for Toyota
I recently replaced 5 cells. I had trouble lining up probably a total of 6 cells to the 8 Millimeter hole/bolts that holds the cell down. It seems pretty sturdy and tight in there without the 8 millimeter bolts holding down the cells. Will i be okay?
I say throw away the 8mm bolts that go up thru the bottom. That way if a cell needs to be replaced, you don't have to pull the entire battery out and flip it over. What say y'all?
Is there a way to level out the battery before fully assembling on hybrid gen 2 way I replace 10 of 28 how do I get it to not throw codes and what kind of reader should I use
Man I wish my parents just did that on their Prius but they just went straight ahead and replaced the whole battery for about more than 1000 dollars. Dad was saying about replacing bad blocks is not useful since the others will die off slowly.
Yes i have this same question!! What charger if not prolong? How many amps to how many cells? Should one just use a charger/discharger ..?? I bout this charger that does trickle charging will it work to charge 24 hours?
I replaced one cell in my 2007 camry hybrid. Put everything back. I have power to the dash and all "check hybrid and check VSC" codes still there but the car will not start... 12 volt battery is good. Any ideas as to why?
Hi there ...bro i replaced the battery cells and every cell is above 5000 mah now ....but when i drive it still shows a code ...what should i do ...i am a bit confused ....can you pls help
I have 2016 prius v I replaced head gasket also replaced a bad model do I have to clear computer because it starts but then 3 minutes after it turns of and all the dash lights come on. It also seas 6 stored codes
Just today I changed block 8 with new cells, putting the new ones on the very front. I assembled everything back, but now my car won't start & I'm getting the (hybrid system light). All battery cells are at 8V and double checked all wires and bols. Do you have any other suggestions what it might be?
@David: Did you finally figured it out? Was it the utility battery (12V) either disconnected, or discharged causing the problem? I am assuming that the high voltage safety orange plug is pushed in properly, and engaged.
I know this was 3 months ago since you asked but if you have a good code scanner or one of the cheap Wi-Fi/ Bluetooth ones the Dr. Prius will tell you which cell is bad
My battery cell 7 is showing a lower voltage than it should, until now ive ignored the issue, but sometimes the car will just fall out of drive (it still stays in drive on the dashboard) Can the battery affect the shifting of the car in any way?
Hi I have a auris 2016 I have removed the battery and checked all the cell voltages they all show between 7.91-8.02 how would I know which cell is bad without a code scanner ? Any help would be appreciated
No comment at all about checking voltage or amps for the modules as if you place one that goes out of the range it will also cause the car to detect a defective cell, you can't take any cell and put it in the battery
If you got cellos going out it’s time to replace the whole battery. Who has time to tear into this thing and order parts everytime one cell goes bad. Just replace the whole thing and forget about it for a long time.
