Reminds me of hot-swapping some hard drives lol Thanks on the clear video unlike most others. But I would recommend using a DC charger and to discharge each cells. Typically the HV batteries don't fail until >=2 cells start to die (from what I gathered). Plus then you can balance load the cells and make it stable (rebuild lasts longer).
Hint for removing the cells. Once you have the pack on your workbench, before you remove the tan end-cap and after you're disconnected all the leads (the orange side attachment deal) turn it up on it's end cap and remove the 8mm/phillips on the bottom while the end-cap is still on. That way you can get to all the bolts underneath easily w/o risking dropping any cells b/c the end-cap keeps them all in place. On my battery, cells (from the connection end) 12 and 16 were bad so I just unbolted cells 12-28, laid the pack back down and then took off the end-cap.
the big question is how do you reattach the compression plate to compress the sticks enough so that you can turn the pack on end and re-attach the 8mm bolts to the bottom of the individual sticks?
Great video and thanks for sharing your knowledge. You have saved me $1000 which is the difference between replacing a cell within the battery pack verses replacing the whole hybrid battery.
For everyone, it's pretty good video but if you service the battery you need to clean the corrosion off the copper connecting bars! this batterys sometimes fails only due to corrosion result in a bad connection so ALL WAYS clean the bars! good luck!
Ah, a good point at 12:50. Compress the battery so the holes on the bottom line up. Excellent video. Thank you. (edit, 3:20) Did you know that the compression plate is on facing the wrong way? The bottom tension bolts can't tighten that way unless you modify the plastic tabs coming off of the bottom of the plate. Att to viewers.
You are brilliant every aspect. Great Camera man!! Educational video starting from highschool students learning technology all the way to retirement and beyond. THANK you so much.
Obviously they were tested. Diagnosing the cells in an operating vehicle is faster and more effective than testing them individually. Of course I had to much confidence in someone else's work but this video should really be redone with accurate helpful info.
Thx for taking time to show us, very instructive. I was expected to find out a connection at each stage of the battery for cell balancing. Apparently its not the case with these NiMh battery.
Excellent, it has been fantastic to watch your video extremely informative easy to follow and it has allowed me as a layperson to understand how the job can be done.
I have a 2015 kia optima hybrid hopefully the schematics are similar thank you very much sir this was very helpful and interesting to learn from instead of paying $1000
Isn't it better to do a load test of the actual cell? Since some cells can measure the correct voltage but have weak power and drop to 6 volts more rapidly than others.
Thanks for taking the time to shoot the vedio, haven't done the fix yet but I will do it this weekend, so if the voltage lower than 7 volts it should be replaced.
Each cell needs to be load tested to find the bad one. I just attach a 12 headlight and time the cell with a load on it for 2 minutes with a multi meter.
Mike T I think he means measuring a battery when it is floating no-load doesn’t give a valid measurement. Because even a weak battery may measure good in that case. But if you put an electric load on the battery ( give it some work to do ) by attaching a light bulb - then the battery voltage measured is valid / useful.
For how long you suggest to put a 12 volts bulb for checking the battery? I started the procedure and giving 6 minutes to each cell with reading before after and again after six minutes. Just want to know what if I connect three 12 volts bulb in parallel in order to save time?
Dr Shakir, I don’t know the Prius battery specifically to give an exact answer. But I will say, in general, that the more current is drawn then the heavier the load placed on the battery. Yes the load would be increased with more bulbs in parallel. It would also be increased if the wattage of the bulb where higher but it’s voltage were the same ( Watts = Volts * Current ). Having said all that, I think your current method is fine because the voltage measured is not a float voltage because you have a load attached. How do the voltage readings compare between the first and second readings? ( Also no need to keep a heavy load on the battery for too long - as doings so could be stressful to the battery. )
I already replace the bad battery cell and measured every battery cell and there all around 7.76 and 2 cells are 7.80. Would you recommend balancing them again and doing the process of discharging and charging them back up
Jzk brother I will change my soon. My scanner say code P0A80 replace battery pack, along with p0319 block 9 weak, and p0320 block 10 is weak. Replacing the cells which are bad will work?
There are many factors in battery reconditioning. One resource I found which successfully combines these is the Magic Mender Wizard (check it out on google) definately the no.1 info i've seen. look at this unbelievable resource.
Interesting video (was expecting that) But i couldn't stop thinking: Touching a charged HV battery (even with disconnected elements) like a maniac, without gloves, by a water puddle. What can go wrong ? Remembered my younger days when i was adjusting HV and Focus on powered-on CRT monitors (just a 15 kV voltage for the the tube grid - you quickly learn to not be so touchy touchy with live hardware) :D
@@tcolondovich2996 Offering battery replacement services to hybrid owners is one way. Although I wouldn't ever charge 3k for such a thing. I'd only charge 1k.
i have problm with my prius that all cell show differnt voltage like that 7.45, 7.37, 7.23 and only one cell show 6.93. please help me which cell i will change? and how can i balance the madule?
The way to "properly" test batteries - is UNDER LOAD. The volt meter trick you did will get you the obvious cells to replace. Under load you might have several more.
The battery cells have been separated. no need to do a load test. unlike the batteries which have only a positive terminal and a negative terminal, these are cells that cannot be tested separately. thats where you do a load test on a battery. you cannot do a load test within a cell. A cell that cannot carry a load up to its required voltage is deemed a bad cell.
eventually everything dies including us... (but better to keep the original part as long as possible.:))...as long as a battery pack is relativity well balanced it wasteful to throw away cells with plenty of life...and it worth a trying to bring back cells with voltage drop back to life too as back up when the next cell fails...
It's interesting to see how much smaller it is than the first generation prius battery and more interesting still to consider that the small 1KWh capacity of this battery could be provided by a quantity of Tesla cells about the size of a loaf of bread. Energy density keeps going up, price keeps going down.
great work! one thing I noticed that the orange plastic strip ( which is actually harness) has corrosion at one end ( greenish) , did you not replace it. On 1st generation prius I used to replace both side harnesses at the dealership due to corrosion.
Do you know if it is possible to create an additional battery to increase the size of the battery and almost turn the Toyota Prius into an almost electric vehicle?
Did they diagnose at the Aautozone for free of cost or you paid? If yes, how much did they charge? Thank you. I inquired at Advance Auto and they say they dont do that.
Good job, I measured the voltage for each cell and they were between 8.5 - 8.7 volts. Except no. 35 was 6.8v. What can I do to control the Over-charging?
Aoa its good video but i have glquestion that u have replace the bad cell its vol is not so bad i think if u balance that one weak cell only charge and discharge and balance to the voltage as other module voltage it was not good if u have done that ???
What make and model are the individual cells? I have a 2010 Lexus RX450h which I believe uses a Panasonic Battery, do they use the same calls? and where can they be ordered from?
You might as well replace the whole battery after 10 years . You just going to have to keep replacing individual cells. That’s about the life of the battery. They probably shouldn’t be in the sunlight either
Here is one of the plethora of listings on eBay: www.ebay.com/i/254341266692?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=254341266692&targetid=882092066536&device=c&mktype=pla&googleloc=9033787&poi=&campaignid=9248523520&mkgroupid=93042821039&rlsatarget=aud-622524041238:pla-882092066536&abcId=1141156&merchantid=6296724
Hi Iman Did you have to balance the units? How is your battery performing now? Did you have any problem since you have changed the cell? My gen2 battery didn’t show the dead signs yet, but time to time suddenly battery level drops fron 6/bar 3 bar and takes ages to recharge. is this a sign of nearly dead battery? Should I make attempt to replace the cell? Or should I wait? Any suggestions please. Thanks
I know just enough to be dangerous, What u described is most likely due to 1 or more of the cells being out of balance ie starting to go bad and causing more resistance. Replacing bad cells will help the other cells last longer since they will to be easier to balance. And even be more efficient since the BMS has to drain off energy to keep cells in balance when cells r dying. But it not easy, so its up u to determine when it worth the effort. And changing each cell individually is most effective for an older battery pack since BMS r never perfect, Hope this helped more than just being confusing,
Very simple to perform, cameraman next time point camera at the very beginning at speaker, to give the audience a proper presentation, of who is the speaker, the teacher of doing the repair.
If that sale is rendering 5 volts I'd say that thing's done it's probably got a bad sale within that module which is 1/2 volt so for 25 bucks and they ship it to your house I just replace it
How long does a normal person need to take battery out and test all cells and replace the bad one and put back into car and be able to drive? 1 hour, 3, 5,8?
Sam Sonn Normal people don’t disassemble Prius batteries and repair them. 👍 I would think you need to disassemble car enough to get battery out, determine number of bad cells, order cells, repair battery, and reassemble. That is 4 half days for me the first time and half that the second time.
Nice video :) Can i have a question? Don't we need to balance the whole battery pack? As i know we need to, because if the individual cells are not on the same charge levels, some cells could get over/undercharged. Sorry for my bad English!
That's a good question. Actually, you need to buy a used battery cell b/c the new one always has higher charge level but the used one is in the same charge level. Also, make sure to test all the charge levels to make sure they are almost the same. Good luck!
This problem mostly occurs when you have one or two bad cells. Basically, you need to check all the cells to make sure that all of them are in the same voltage level. Just like the steps that I showed you in this video
Brilliant guide. So many people replace the full battery pack on their Prius' when it's not needed.
As others have said... thank you for sharing your experiences of how to go about this repair project ..great!
Doing mine right now. Picked up a 2004 Prius that needed the HV battery replaced for 1500 bucks. Great video! Very informative.

It's good because one cell with 6 pcs 1.2v cells in series. and from this package there is one 1.2v cell, in a way, in Oikari.@@muhammadumair1836
Hint for removing the cells. Once you have the pack on your workbench, before you remove the tan end-cap and after you're disconnected all the leads (the orange side attachment deal) turn it up on it's end cap and remove the 8mm/phillips on the bottom while the end-cap is still on. That way you can get to all the bolts underneath easily w/o risking dropping any cells b/c the end-cap keeps them all in place. On my battery, cells (from the connection end) 12 and 16 were bad so I just unbolted cells 12-28, laid the pack back down and then took off the end-cap.
the big question is how do you reattach the compression plate to compress the sticks enough so that you can turn the pack on end and re-attach the 8mm bolts to the bottom of the individual sticks?
thx, I was wondering if it could be done that way...once the nuts on the compression plate were loosened...

If a few cells are bad you should replace them all for peace of mind. You you also use some PPE, at least dielectric gloves & safety glasses.

How long does a normal person need to take battery out and test all cells and replace the bad one and put back into car and be able to drive? 1 hour, 3, 5,8?
Sam Sonn
Normal people don’t disassemble Prius batteries and repair them. 👍 I would think you need to disassemble car enough to get battery out, determine number of bad cells, order cells, repair battery, and reassemble. That is 4 half days for me the first time and half that the second time.
How many amps per hour will one cell deliver? Or rather what's its usable capacity of a single cell?

Not necessarily. Once you plugged in, it will be charged while your car is on.

Isn’t it a bad idea to mix new cells with old cells?
My question is will these 17 cells may have got damage?
question if the one cell go bad is there chances of other cells goes bad too soon or not to worry?
