Reconditioning a good hybrid battery Part 1 of 2 

THIS VIDEO IS SUPER AWESOME, I ALWAYS EXPLAIN THIS MY CUSTOMERS RECONDITION 2 TO 3 YEARS ACCORDING TO YOUR DEIVING MILEAGE BUT THEY ALWAYS THINK YOU SAYING THAT TO JUST MAKE MONEY FROM THEM

Love this dude! He needs a camera crew for all these gems. Thank you!

Fantastic! Such a simple explanation. I think this is what has happened to my wife’s car. Unfortunately don’t know how to get the system balanced. The dealership will probably deny any knowledge of this! 😄

Full details on every steps . Well done. Thank you

Really it is the best video that is exeplaining how to fix the hybriid battery...thanks alot..

Just wanted to say 'Thank you' for your very helpful videos. I was able to get my 2008 Prius back on the road. I appreciate it.

You are the best, respect from Afghanistan

Jose. As I was listening I said to myself this guy is a Cubano. When I heard you say “tuko tuko tu” I said Coño este tipo es my Hermano. Excellent video you gained a sub. 👍🏼

Awesome 👍 Thanks Boss ☺️

Thank you for a most imformative video, well presented.

Amazing channel thank you for this information!

Good job

I like the presentation skills involved. Can't exist the video.

Excellent explanation!

hello thank you for your video, professional quality, can you give us more details on the charging device and the discharging device used and how to reproduce the same connection.

Best Regards from Poland

thanks a lot for your effort Very useful information

You are supper good ! 👍

Interesting video. Like to see soon how the battery is performing now after maintenance. 👍

highly eloquent and persuasive explanation, congrats bro, we indeed take highly advantage of your ingeniousness, BWT could we have the simulation program of the battery cells to be used in our college?!

these are good videos

Good 👍🏻 job vato !!!

Me encanta como te explicas. Gracias desde España.

Parabéns pelo trabalho e pelo profissionalismo. Obrigado por compartilhar seu conhecimento!! Thanks a lot!

Amazong video, thanks!

great professional congratulations greetings from Italy

Usually these NiMH modules loose capacity due to aging or heating ( specially the cells located in the middle of the pack). you cant check the remaining usable capacity of individual module by cycle charging the whole pack. There is no point of cycling if cells have different capacity.

Hi I m much pleased to see your videos about hybrid car problems and solutions. I m using Toyota Aqua 2013 and recently showing the hybrid battery sign .All cell pack voltage is 17+ each. Please share your opinion to solve the problem . Thanks in advance

very good

very nice

I really enjoyed the information you shared on your RU-vid channel, I have a Hyundai sonata that has sat for five years. I don't know why it was left to sit mileage is around 140k hybrid battery is dead and I need to put a 12 battery in it also. Any thoughts on getting it to run. So I can see if engine is good without buying a replacement hybrid battery?

What equipment do you use to charge and discharge the battery and where could I buy it?

I've been watching your videos for quite long time. Since last year hybrid cars started to be sold in my country Colombia and I see a huge business opportunity here to offer the service of reconditioning hev batteries. I would like to know where I can start and if you can sell some advices about the equipment and how I can start my own business here. Thank you so much.

Great work on this and all of your videos.

My Highlander Hybrid 2008 working flawless. Do you recommend to send the battery for this kinda reconditioning process? Thank you for your reply !

I'm confused. I've seen videos where they hook up to each individual cell to discharge and recharge, with wires going everywhere, but you just hooked up a few leads to discharge and recharge the whole pack as one. Could you explain? Also I've seen people line the cells up in parallel to balance them? Thanks for your your knowledge

Hi! I purchased used BMW Activehybrid 7 2011 and now facing the issue with hybrid battery multifunctional signal. Please advise what should I do?? I couldn't find any clip on RU-vid related to BMW Hybrid Battery 😞

Very nice sir. From where can i buy a hybrid Battery charger? & which one is better?

An question, I have this 2010 toyota prius that was popping check hybrid system once or twice a month but after cleaning bus bars I get error on every start up and sometimes during driving even if it was cleared at startup?

Hey Jose, great video as always. I want to ask how often do you get swollen modules when you remove them and do you replaced them with used modules of similar SOH? I want to service my hybrid battery but bit concern about not refitting cells back if they are swollen! Its shame that I can't come to you as I am in New Zealand.

Hello Jose, tell me is it possible to restore a single element in this way by discharging it with a current of 0.2 A and charging it with a current of 0.2A ? First up to 4.7 V, then up to 3.6 V and at the end up to 3V?

I love you man

How do you fix the corrosion problem in the voltage sensor plug?

Can I see any cell voltages before opening the battery? I get very poor range on ev mode on my yaris 2012.. battery indicator never goes to 100% or below 2 bars..

Hi, I replaced 2 modules on #6 block that was showing bad, but its still showing same problem. Could something else be wrong other than the modules? Thanks

What is the program or software you are using in the simulation ?

Hi, Thank you for the video.I have a toyota prius 2010 and it gives me ( P0A80 ) and I did everything in the video and drove 350 miles. After this the code didn't go away. Could you help me, what else can I do?

How do you understand if any of the modules are in bad condition rather than just unbalanced so you can got and get a new module to replace it?

Can an Launch X 431 read HV battery behaviour. Like monitoring individual cell?

Here, with the Prius and cars like it, no one I know has this equipment/instrumentation to rebalance an EV or Hybrid battery nor do I know of a shop that does this. Is there any way I could find out what software you have hook up to battery , Your VIdeo Just Makes Good since!

HOWdy H-S-D, ... Thanks GREAT INFORMATION COOP the WiSeNhEiMeR from Richmond, INDIANA - USA ...

I have a 2006 Hybrid prius and would like to change my high voltage battery. Any guidance ?

Parabens mano

What is the best way to keep the Hybrid battery charged when the car is not used for a few months?

i have a 2012 Infiniti M35h i want to recondition the battery also, i was wondering how much it will cost me to do that?

Do you have to take the battery out of the car in order to only balance it ?

Thank you for this interesting and informative review, but is it possible to make an evaluation of the Kia Sportage Hybrid Battery?

I was going to say the cables to the discharge unit looked very thin, but then you mention the discharge current is actually quite low ...

And Boss what the voltage of one single module deep discharge ? One single module full charged on 7.8 volt ? And what the deep discharged voltage?

On dr prius app shows temp three higher 115 how come.not middle one so shall i move them

I have this car 2019 has P0A80 replace hybrid battery will i do the way you're doing or i just replace the battery

hey would it be possible you can show us how to charge a gmc yukon hybrid battery mine went dead but would like to charge it at home instead taking it to a shop again.

It sounds ok to re-balance cells. But what about the internal resistance of the individual cells. Cells will not age equally and IR of cells will increase as they get older. Since the rate of change is unequal, cells with higher IR (more than 10% difference in IR) will loose more charge than others. Over time you will have imbalance again. Effectively back to square one. I think you should get yourself an IR meter and measure the IR of individual cells ensuring they are within 5% of each other which is what I would do. Otherwise you are OK.

buenos noches Jose, entonces primero hay que balancear el paquete, luego cargarlo y nuevamente balancearlo?

Hi please recommend me, Hybrid Battery balancer or charger, discharger system or want to work on professional just some struggling about the system. I’m already auto Mechanic thanks

To prevent Corrosion in the terminal cant we use Vesline cream. I used it to auxiliary battery terminal which makes keep the terminals as brand-new. (Dont hit me virtually lol)

Would you use the same charge/discharge steps for a battery with LiFePO4 modules, like Nexcell's?

Thanks you ser my name is Mustafa for Nigeria good job but what is the sing the car with geif you when it have betry problem please

He'll my friend. Where can Where can I find the charging machine?. Please thank

Is there any fire danger? I can see the melted connections. That means as you say overheat. Are we in danger? :)

Hi , where can i buy that cable to make my toyota hybrid a plug in hybrid?

Greetings Sir Jose! Thank you for your meticulous detail! I have a question that pertains to something you said about the temerature differece between the 3 sensors that measure the hybrid battery. i have a 2006 Hylander Hybrid that has the NiMH modules, as you know. I am getting a 4 to 5 degree difference in the temperature between the 3 separate fans that control the temperature. Is this normal or is there an internal problem or what do you suggest? Thank YOU!

The information you provide in your videos is priceless, I'm applying it to my GEN3 Prius with the standard NiMH, and for that I thank you very much! I also own a 2022 Prius still brand new w/4K ODO running lithium battery consisting in 56 cells (no modules) -question: is this battery serviciable? like... can you rotate cells, clean busbars like you would do in the NiMH w/28 modules? I wasn't able to find any inforamtion about this battery but I have a feeling this is a sealed system /disposable --any thoughts? thanks a lot Jose!

You can do the balance by putting the + on a roll and by default the - on a roll for 6 hours .. it will balance by itself if the battery is 75%. You don't need all this time to do it.

What do u think about the 2017 nissan note epower compared to the aqua on maintainance and life expectancy

Can you recondition once you get a p1b74 code?

Very interesting, im curious to know what would happen when the first battery bank depletes. Does the system stops to provide the electricity or continues until all banks are depleted? If all banks reach the depletion, wouldnt that rebalance all battery banks?

Which weather is worse? I lost a lot of battery compacity in my PiP during winter. So both summer and winter are bad? I'm in Las Vegas.

Hello, What software or website are you using to show the cell balancing @7:48? Please let me know. It'd be great to show my students with that!

Please where can I find the charger to charge

I am in Southern California Just outside of Los Angeles can you help me or can you recommend someone.

My Toyota Aqua is 2014 model.. Please educate me. Life expectancy test showed 73.50%. Ck voltage = 137.24v, Blade Voltage : 6.86v Piece of word is missing here, I can only see T E of charge 39..61%, CURRENT 56.18Amp.... Charge Power 19.43HP

Para aumentar a autonomia (aumentar o número de células do Ford Fusion 2015 ) e que tenho bateria Ford original Hybrid e tava pensando em fazer a continuação das células . Será que é possível

Boss give me some tips. I have no that charger so if i rebalance all modules and reassemble again but not contacted bus bars and i contacted all modules in parallel with jump wires and and charge with 12 v battery charger and when the all modules reached 7.5 volt its means its charged fully then i will discharge with 6 volt halogen bulb💡 which takes load in . Points. That's idea work or not ?

If you discharged the battery down to 84 volts, aren't you discharging individual modules down to 3 volts? Isn't that way too low? I read that these modules should not be discharged below 5.9 volts and some say even 6.3 volts.

Hi, José From Puerto Rico. I have a Toyota Prius C 2012 with 44, 000 miles That Was involve in a front car accident in 2015. The car Was Stop in My yard From 2015 to 2023 Stop. I buy the 12 volt battery and only start light dash with Orange triangle but not go on the combustión engine. Question? Did You Thinq the hybrid module battery can Be recharged and It Be Ok. It has Been 8 years Without charge! The car Is in excellent conditions and I Will Like to bring It to life! What Your advice. Hybrid technology fan Always 🙋🏽‍♂️

Is there no balancing at all? Or is the balancing passive (resistors in the bms)? It's hard to believe toyota didn't do something to mitigate this

I would like to see how to do chevy volt batteries.

Does any new Toyota battery have self balancing system?

Hey I live in a island in the Caribbean name St vincent an I have a toyota aqua hybrid 2012 needs a battery don't know if u can help me fine a place in the US to get one

So, there is no way to force a rebalancing by some sort of "rebalancing program" within the car? It then needs to be removed, deeply discharged and slowly recharged as you have done in both part one and part two of this video? And, you recommend doing this every 3-6 months??? First, this is no DIY process. One would need the equipment and instrumentation you have to do this "reconditioning" properly. I totally agree with everything you have said in these two videos because I work with LifePo4 cells in a solar system. The importance of balancing is the same. However, I can actively rebalance myself if they get too far out of balance. Here, with the Prius and cars like it, no one I know has this equipment/instrumentation to rebalance an EV or Hybrid battery nor do I know of a shop that does this. As such I find this video interesting and technically correct but frustrating since I can't do this myself. How about manufacturers putting in a BMS with an active balancer either to balance automatically when cells become out of balance to a certain threshold or a program in the digital display in the cockpit to be able to manually activate a rebalancing? Not many EV/Hybrid owners know about this and you are the only one I've seen even mention the value of rebalancing one's Lithium Ion cells let alone find a shop locally that might know how to do it. In fact, I question whether the dealership would even know how to do this. I'd be their solution would be; "you need a new battery." I would love to refer individuals to you (within geographical limitations) but it appears you do not like to reveal your location. Not sure why if you run a business but that is not my concern I guess. Additionally, it also appears you prefer TikTok. I, and many like myself, refuse to use TikTok for obvious reasons. Thanks for your videos. Just found you through ScannerDanner.

Regardless of how the problem happened or even how to fix it. Does this mean to say the battery management system was not doing it's job correctly?

If the battery pack is bad how do you know which cell needed to be replaced? Your charger cycle all the cells together.

How do you clean that filter. I know mine has to be dirty.

If you have 300k miles on your car and need to replace your hybrid battery, the chances of your car lasting another 15 years and another 300k miles are slim to none. So paying to replace the hybrid battery might not be worth it. So basically the car needs to be retired after the hybrid battery goes dead. BUT....if the hybrid battery goes dead, can you still drive it? Will you get the same mpg as that same car in a non hybrid version from that point on??

So why couldn’t u just mount big fans on top of the modules blowing cool cabin air down on em

The battery might have died because you can't leave these Hybrids sitting without running as they will self discharge after a few weeks sitting?

Surely you get a few more years out of it but it's an aging pack with limited life remaining? I'm curious what your view is.

Does this process work with the 2010 to 2015 Toyota Prius?

how long has this battery been in use? jose
