John, awesome video. I’m starting to get the CEL with hybrid battery related codes on my Escalade Hybrid. From what I’ve read the Toyota battery is the same. I just have 40 modules. Thank you sir, this is very helpful as I am going to begin my battery rebuild process. 👍🏼

Love your stuff! Have a good evening

Excellent work.Thank you.

You did good as a DIY like me, by load testing the batteries. You cycled them individually on the charger and repositioned in arrangement for equal power strength. What you did may add up to two more years of use on the hybrid battery.

Im so glad you spent my time learning to count!!

god my man you are a genious. Thank you, we need more men like you. God bless ya

Great video, very informative, easy to understand

Thanks for the info, just getting round to doing my prius nw20 on 228k miles.

All these hybrids using the PrimeEarth Panasonic Prismatic 7.2V modules in their packs are starting to age, people will be very interested in how to save the old battery modules especially since the value of a new Hybrid battery pack could easily exceed the cars value! An RC type charger that works well on these is the Turnigy Reaktor 1000W 30A unit. It will discharge at 6amp and charge at 2amp (OR HIGHER). It also data logs back to your laptop. Great way to check the overall health of each module and identify correctly the ones that need to be replaced. Problem is that to do this is very time consuming, if you have strong modules that are close the the 6500aMH original rating it could take

Note: On the 2010 there is no temperature sensor on the bottom. I also find it easier to remove all the hold down nuts first of the hybrid modules when removing modules. The two opposite nylon hold down caps will keep the modules from falling out. Therefore remove the nylon hold down cap opposite the computer section this will then give you access to remove modules. So much easier.

Damn good video sir.

Just so that you don't forget, the cells are numbered right to left ok......

EXCELENTE estmado el compartit tu experiencia para le conocimiento de quienes desean reparar la Bateria hibrida

Awesome... thanks mate, good explanation..

I'm pretty sure it's numbered right-left because it's a Japanese made car, and they read right-left. At least in books...idk about how they write for numbering things, but that's my best guess.

The Fluke meters normally have auto range selection from 0V to 1000V so you don't have to care about range selection. I have one very old Fluke 73 from my Pop's days (1980s) still as good as Gold.

nice, great job !

Thank u.very helpful

Sweet video broseph

Thanks for fantastic presentation. Please let us know which software is used to check battery status. Thanks

Thank you John for amazing video with showing voltages in different modes. I am ordering im6 v2 unless you have any other remoandations. I have 05 prius just got cell and I was about to put it back but realized its A must to balance it

Good video!

Which torque plugin did you use it..LOVE YOUR VIDEO - EXTREME DETAILED.A+++++++++

THANK YOU FOR YOUR VIDEO IS WHAT CAN YOU TELL ME BLOCK 9, BEGINNING TO COUNT FROM ECU (COMPUTER OR DRIVER SIDE TO PASSENGER OR THE CONTRARY, IT OR THE POSITION OF BLOCK 9? THANK YOU

Excellent Video. Thank you. I just bought a Prius with a bad battery, so it will help tremendously since I'm technically inclined so I'll fix it myself now thanks to your tutorial. By the way, can you please tell me what that battery software was that you were running on your Samsung....is that through an OBD2 sensor? Let me know please.

Awesome thanks!

good info. where did you buy battery charger? my car is parked for 3 years. any pointer you can tell me. I will appreciate that.

Hi John, when you was cycling the modules, what capacity number usually was satisfying for you?

Interesting video John. I had to watch it a few times. You mentioned that you had to cycle the batteries about four times each. May I ask why? Does that mean you had to discharge & recharge each module four times? Also, after cycling the batteries, how can I check to make sure that the modules hold a steady charge? In other words, how do I prevent reinstalling/reusing a bad module?

Excellent video, thanks for the information. What kind of software or app do you use on your phone to see the voltage. I use a LEMUR BlueDriver and my iPhone to check codes. I wonder if I can get an app to make it show me the hybrid battery voltage with the LEMUR Blue Driver monitor.

Thanks for the video . It help me have a better understanding of the batteries pack . WHERE CAN I DOWNLOAD SAME APP AS YOU HAVE , BUT FOR AN IPHONE THANKS

Thanks for sharing this great information. I am researching the effects of heat on these battery packs. Accordingly, which module numbers--positions--did you ultimately end up replacing?

Looking from the opposite side it would be left to right. The danger label in the middle reads upside down so logically it must be in the manufacturing line put together from facing the other side.

hi, John! thanks for video! it's awesome! Could you tell me what soft ware do you use in your mobile phone?? and how did you connect it with a car? thanks in advance

On my 07 Highlander I have a module reading 9.31V and the rest reading ~10.64V. I bought the Turnigy Quad 400W and noticed that it doesn’t discharge any faster than 0.4A even though I set it at 1.0A to 8.0V. Would it be safe to discharge to 1V per cell using a high amperage draw like a starter motor? If not what is the fastest and safe method to discharge each module?

Just wondering, if the RC chargers work as dischargers as well, how come you used the DC motor to discharge at the beginning?

I read recently that the direction of numbering can change between versions of the Prius - but that they are all numbered with number 1 next to the negative end of the pack...

Where did you get the app for cling the batteries?

How long the whole process took you, and did you have to charge/discharge them all, or just the suspected ones?

So I just a Prius and that red triangle is on but the car sat for just over a year with an engine ticking noise, I believe spark plugs, fuel injectors or the EGR system maybe plugged as far as I can tell, Im sure once I get it down the road it will charge the system up if not looks like im doing what you did.

There's a way to charge the battery . Still reading it . Good morning to you my brother . Stay blessed always .

i have my torque pro app . got a POA80 code on my prius 2012. when driving , all my modules show 15.5 and all go up to 17.8 V. during active driving. is there a way to check and detect a bad cells with torque pro app , not taking out whole battery and load testing it ? when the engine stops ,and AC is on , how fast must the voltage drop ? till what number ? 13 V or lower ? what is the normal drop rate in this case, when AC is on , on neutral with engine off ?

Is this charging method the same as when the sellers online say its "reconditioned/refurbished cell" ? and they get around around 8V also

Thanks for that tip at the beginning. Easy mistake to make. Glad I didn't!

Hi John, Thank you for sharing your knowledge. I understand the software to analyse the performance of the batteries i.e. TorquePro App and in conjunction with an OBDII Bluetooth plug in device. There are lots of these OBD units on the market. Which brand/model OBDII device do you recommend? Thanks again!!

You need to wait at least 5 to 10 minutes after you pull the orange plug to discharge the capacitors. You can still get killed if you touch it.

So, when yoy blew up the other colt meter how did you do that? I feel like its hard to touch the positive to negative across like that and arc them with the volt meter leads? WAS THERE ANY DAMAGE TO THE BATTERIES?? please let me know. May have done rhe same thing just in a different way lol

Dealership told me I needed a new battery but I checked all of them there good 7.98

I have questions. My charger can discharge above 1amp on this prius battery. What's the maximum discharge ampage I should use? 2. I set mine to recycle 5 times and out off at capacity of 7500. Now once it's start discharging and charging and it out off at 7500 I stop. Is this a bad idea? 3. I couldn't set maximum voltage to stop charging. Mine some times shows charging at 8.6volts. Is this right?

Thank you

It's been awhile since you're done I presume, is it still holding up

Looks like the cells away from the t senders aged faster, not just on both sides. Don’t you think?

Great video. Just wondering, why did you use that motor to discharge the modules instead of that IMAX device?

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?

Do you know how to reset the lights once cells are replaced?

I am not surprised on how they sequentially count from right to left, Japanese books are read from back to front!! That is how they do it!!

In case you want to know... Japanese reads from right to left, not left to right... perhaps that is why they numbered the cells that way.

Hi John. What is the software you used to monitor the cell blocks?

hey love you video. does your prius has the car with key lit up.

Is that regular torque app pro?

the level of corrosion on those jumpers, is what killed those cells.

Once you are ready to place the hybrid battery back into the prius how much should each cell be charge to?

Just wondering if you have EE ?

Dear what is this softwere in your phone and how you connect it with your car

Excellent! how long did it take you to recondition the whole pack?

John are you in oklahoma?

good

Thanks for sharing just subscribed question what's the software that you're using for Diagnostics on your phone.

where did you he app for the battery fro your phone !!!!!! what is transmitter ????

What’s the nominal voltage and max for these cells? And at what voltage should you consider to throw out and replace a bad/faulty cell?

How much time did this cost? It seems like the car would have been disabled for at least 2 days during the 4 reconditioning cycles, hence two chargers.

Those packs isnt that big. Could use 2 of them for better mpg?

One Question HOW LONG CAR WAS RUN ON THIS reconfition ??? I know who replace with couple new battery old one, got the same problem ,new battery destroyed good old one. Thanks

What software is that which tells you the block voltage individually?

John, what is the name of that app you are using?

What app are you using?

That's an auto-ranging fluke DMM you don't need to change the decimal place

How do you get the volt meter on your cell phone ? 😮

Hi Can you please let me know the name and model #of the scan tool you used? thank you

Do u fix the Chevy Tahoe hybrid 2008?

It's probably reading like that cuz it has a leaky cell causing the triangles of death to come on with the p0aa6/612

How about more info? What year is your specific car, where do you purchase the Prius software for voltages?

My heart is racing as he touches things! I can tell you know what you are doing. I would likely electrocute myself.

Googling "DIY Grid Charger" may be of interest yo you. Gives you a low-cost way of balancing the entire pack all at once.

Please answer my question if you can. I have a 2011 Chevy Silverado 1500 hybrid I want to change 2 modules. What modules do you recommend?. I hear some shops are using new generation modules. Can I use any module?

On the matter of corrosion; why not use dielectric grease on all those bare connectors. Coat them all before assembly.

My 07Prius had big power loss. Shows dash panel light on. Has 185k miles. How many cells do you think I may need? Thanks

Used this video, great stuff. I have an issue. Removed the Battery Pack and checked Voltage and all read on average 7.7 Per Battery and 15.4 per Group. There are no batteries that are far from the 7.70 with the low being 7.59 and the high being 7.77. I figure since I have it already on the bench I should Discharge and Charge. I only have two of the IMAX B6AC V2 units. The CAMRY has 34 Batteries. What is the value of doing the DIscharge to 6 Volts (1 Volt Per Cell) the Recharge? THis will take 2 hours for one Cylce. The number above is for one Discharge Recharge with top off twice only one cycle so is three cycles needed and/or what is the value of that? Saw instructions saying to go below 1 Volt per cell with .08 then .06 then .05, is this really of value? The Battery was on a Camry 2008 that I gave my son, it drove here no issue then gave VSC and Check Hybrid System. The Freeze data shows the packs fell from 15.4 on average to around 12 to 13 volts per pack. I think this is caused outside the pack, but now it is out want to get it redone. Any help or comments would be appreciated.

did you notice any increase in mpg after doing this?

When it is being charged with engine on, it looks good working, but what it matters is when it drains batteries. Close to 7.2v bad cells significantly makes volage difference, or when it seats for several days. It probably is temprary fix,

Why are you using your chargers on NiMH settings with a lithium ion battery?

Still working good?

What is the tester and app??

There are 3 Thermistors attached to the middle and ends. They are easy to break off and not stocked by the dealer. Be careful!

My Prius have on the top of the car something like look like solar panel but i do not for sure can somebody tell me what is

What app did you use?

How do I get a software on my phone that can show me the voltages as it shows on your phone?

You can hold the break step on gas in drive and fully charge it into green when you leave it sitting to condition keep in fully charged I’ve rebuilt both my 2004 and 2008 Prius’s

Don't mess with the battery, if your going to do it replace every cell. Do not replace individual cells.

Better to just skip the batteries and instead take every juice out of linear generators while taking all the possible advantage also from solar and drag resistance. So what if it's not "zero emission", but mostly? 10-20kw power should be plenty of torque and speed for most commuting, be that personal or cargo. 2nd gen ev smart has 20kw motor and 100km/h top speed, I would see that would easily handle majority of traffic with a better power source and AI.
