Not to undermine your safety message, but beyond taking proper precautions there is not much cause for concern about the battery voltage - about 275 VDC. I developed an interest in electronics when I was 12 years old and was working on the old vacuum tube radios for nearly 20 years after that. Long story about how it happened, but when I was 14 years old I got 300VDC very solid contact with the palms of each hand. It was quite a jolt - I felt like I had been hit in the back of the head with a 2x4 and things got dark for a moment but I remained standing. If it had been 240VAC I would not be here to tell about it. I worked on tube type radios for about 14 years as an avionics technician in General Aviation (small planes). I couldn't even guess how many times I got my fingers across the 275VDC supply for the venerable Narco Mk12 series radios... many dozens of times for sure. It was like getting my fingers in a mousetrap but it stopped hurting in a couple seconds. Again - take the proper precautions. Toyota makes it very difficult to get across any of the high voltages but we have the responsibility for our own safety.

Bro! your safety precautions warning was great, suggesting to follow safety protocols were also appreciated, however, I wish if you would have showed us the details how you did it to yourself instead of doing it in the dark and hidding from the viewers. Most of the audiances are intrested in how you did it so we can learn and follow rather than displaying what your finished product is. Reagrdless, it is still a great vdo and lot of helpful information to perform the job on our own. Thank you.

Explanation are clear, how to exactly determine the middle modules are weak

Amazing video, very informative. Thanks for sharing and keep the good work up.

Great Video. Thanks. Which level of SOC would you recommend in preparation for long periods of non-use of the vehicle?

Awesome video. I don’t even own a Prius but was curious to how’s it’s done.

Thanks brother for sharing your video. Really appreciate your time. All the best 👍

Great content Bro, Thanks for sharing👍 Stay Safe👍

Great video, well said! I have been trying to find out about where the dust would collect behind the fan and how important it would be to check it. I am at 100K for a 2017 Prius Gen 4 and there is nothing about what is behind the fan and cleaning any ducts that could potentially be clogged. I was quoted just under $200 to clean it, but i have seen where at least one other was quoted over $750 to clean it.

Very detailed, comprehensive, step by step & easy to follow. Thanks a lot for sharing. God bless you.

Thank you learn a lot ❤️love from Kabul Afghanistan 🇦🇫🙏🙏🙏🙏

Great Work. Thank you for sharing

best video thus far :) as a girl I am learning so much..cheers

Hi, I watched a lot of your videos. I did a full battery service on my Auris 2016 according to your instructions also the battery balancing with parallel connection of all modules for 48 hours with great result. Dr. Prius life expectancy test says 87.25%, before battery service was 76%, that is great THANK YOU.

Jose Thanks for another amazing video, wish you could do one with an Infiniti Q50 or link any videos to similar Nissan, keep up the amazing content

gret jo with this video. i have learned alot from this video. fromwhat i see, this system is exactly the same a the prius battery, only that this has fewer blocks. I am loving yourcntent from Nairobi-kenya

Just learned a ton from you... thanks

Very good and detailed. Thanks for your expertise.

Brilliant video, thank you for sharing this Technic

Awesome & great informatuve video..thanks 🏵best like🏵

Cheers mate very helpful video

Thanks for the advise

One of the best tutorials I've seen, a small note, a recommendation to work with gloves, preferably for a fault voltage of 1000 volts Another thing, why don't the car manufacturers bother to connect the car's air conditioner or a small air conditioner dedicated to cooling the batteries. Another thing to consider is the replacement of the jumpers between the cells, a chemical reaction between metals must be taken into account as well as the durability of the material for hundreds which is not that significant, I would replace the jumpers but with the same type of metal that the manufacturer provides. Rare video good job. Michael

Hi dear You are amazing teacher Like to request you to please advice how to change language on radio and flush board on Toyota axio hybrid 2014 model bought in Nairobi Kenya in 2022 January Used in Japan for 7 years Millage is low around 18000 km only Can not enjoy radio and can not adjust or read ad all words in Japanese Kindly advise what to do Some radio technicians tried and failed God bless you

Very useful thank you ❤️

Thanks for the video and and detailed explanation.

awesome video

Great video . Thanks 🙏

Thank you my teacher

That is really good and educational thank you sir

Great stuff. I need to take your training classes. How can I do that and when?

Love the video

What the best reasonable scanner tool I can use on feilder for full servicing means auto bleed an battery services etc

Great video !! Love the content.

Thank you, I really in joy it

At the 33 minute mark buddy touched the battery bare handed when the interlock was engaged……

Does Toyota do this type of maintenance? Will this void the 12 year warranty?

Hi, I hope you're doing well. I'm following you from Afghanistan, and I must say your tutorials are excellent; I truly appreciate your efforts as they are lifesavers ;) I own an Aqua, and while scanning with the OBD scanner, it showed that the voltage of block #4 batteries is a little weak, registering about 12.4V. Upon opening the battery pack and testing with a multimeter (set to 200v), most of the cell voltages ranged from 8 to 7.53V. Subsequently, the dead battery sign appeared on my dashboard. However, after clearing the codes with the OBD scanner, it disappeared completely for a few days before reappearing. What is your suggestion? Should I replace only the block #4 batteries or the entire battery pack? I've been considering an idea: if I were to remove the batteries from block #4 and replace them with one battery from block #1 and one from block #10, would that potentially resolve the issue?

Perfectionist 👍

can a Imax B6 Li Pro balance Charger be used to do the cycle charging please

Great video

Nice one

How long does this whole process take? The removal of the seats, cleaning of battery, reassembly of battery and seats?

Beautiful 👍

Thanks for the video, I have a camry hybrid 2007, is ok to clean the bus bars with hot water and vinegar to remove the corrosion and reinstalled?

Respect from Pakistan.

love the content bro

I liked the tunes in the background. Excellent video!! Do you find you get better acceleration once service has been completed?

thank you great video i learn a lot from you but i have one suggestion please turn off the music from the videos . thank you

Hey Bro! Your videos have really helped me understand about hybrids. The technician here removed vent tubes(rubber pipes for air)above hybrid battery modules from my Prius 1.8 2011 saying they are not needed but Toyota must have it for a reason but then i see fielder & aqua batteries also don’t have it so what should i do?? Kindly reply.thanks!

Thanks a lot. Would you please tell me about decoding the battery serial number? (for nx300h)

Would like some more info on the charge and discharge process

Hello Sir , Is it correct to fully charge the batteries before installing the batteries in the car?

Boss just subscribed, I have a 2014 Camry, engine went into a limp mode, I pulled the battery. All terminals were corroded, cleaned and polished reassembled, car doesn't start. It does show the battery is charged and green now which previously it was purple and dead. Any idea why it has a no start, my OBD2 scanner is showing no codes :(

Where can you get new packs? I can't find them anywhere.

Great work. thumbs up.

So where do you source your parts from ? I’m in Australia and there are NO HV battery parts suppliers here . I have a 2010 Estima E-four -G . 2.4 4 cyl 4wd hybrid . I need a battery service .

Very simple and good advice, thanks. I have a question if we do this procedure and move the banks from center to shore. Does balancing batteries still make sense?

Hi very nice..I need honda vezel HV battery lesson as well.

Do I have to service my hybrid battery every year as you mentioned in an other video? Or is that not required for the lithium ion battery which is in the 2024 Corolla? Thank you.

Where in Trinidad 🇹🇹 are you located?

19:53. How much must be the voltage difference of the packs? I've read some say 1.2 volts is the limit, others say 0.4 is the limit. I cant find an answer...

I can do all of this…but I don’t have the charging equipment. So, should I not bother to specifically disassemble and reposition the cells and reassemble?

Very detailed information was able to do the servicing myself but had issue with the ratchet handle short circuit two of the battery terminals did a voltage check and the level was fine, but after reconnecting and tried starting (Hybrid system failure) came up on the dash any suggestions.(only the orange lead from the junction box was connected at the time

Thanks you.Can I know what is obd3d code I got that code with Torque pro diagnostic.It's a Toyota Axio hybrid on the dashboard it said Brake system check

Vous les avez acheter ou les barres ?

Sir,Do you have video for Venza Hybrid maintenance?

I have a 12v battery charger that im wondering if i can use it to charge my ba ttery pack. It has two settings one is 12 volts-2amps and the other is 6volts 6mps ,which one would you suggest if any

Wow....

Can you help me? I'm in the US and I need the orange ECU wire harness or temperature sensor for 2013 Camry hybrid US /JAPANESE spec.

Hi, I've heard that very important that reconditioned modules' capacity to be close to each other, some say variation should be no more than 200mAh, is it possible equalize capacity? I am reconditioning my gen 2 Prius modules now and see 500-600mAh variation. Thanks!

Surely the battery vents not being connected to an outlet pipe is speeding up the bus bar corrosion? If a cell vent pipe was directed to the under side of the vehicle, the corrosive vapor could be neutralised with a small container of alkaline water, baking soda for example. I recently bought a used C battery for experimental purposes, the bus bars were badly corroded, but the cell voltages were all similar around 7.6v. If the bus bars were tinned with solder,maybe the corrosion would stop, or at least be delayed. Too much trouble for a busy mechanic. A conductive assembly paste could be an alternative solution. Re the overheating of the middle cells, some small computer fans could be easily fitted, preferably under the cells.

Hi, does the Toyota Voxy/Noah have the same Hybrid Battery as the Aqua?

hello, I have had problems with a prius C, I have reconditioned the battery and it still shows failure, when I read with dr prius it indicates voltage values that do not correspond to reality. Any recommendation. all cells are in good condition and balanced.

Hi... Does hot weather affect batteries? I'm talking about more than 51 degrees Celsius?

Подскажите где можно купить такие перемычки для батареи

Hello please where did u connect the prolong battery charger wire to

Where are you located ?

Do u recommend re conditioning every year for Axio ?

My car has 211000 miles shall i change cell places alao dan is clean but sometime overheat warning come on

How often should the hybrid system be serviced?

were can i buy battery cell for toyota Camry hybrid 2009?

Is this block location also identical to aqua 2012 ???

Isn't that covered under warranty?

Where are you located

Hello Sir, I have check all of my battery cell its 7.9 each but still msg come in dashboard. So I decided to do as you show in this video but I am a question should I need to charge as you charge in this video with prolong because I don't have this in our country in Bangladesh

so when i send my car to toyota for a £190interm service or a full service £310 do they do this to my battery?

Your location?

Hi sir I am from Bangladesh i have talked with you on Facebook a while ago about hybrid battery reconditioning equipment. I've forgotten your Facebook I need it for some discussion.

i repair it every day

I fixed all issues on my Prius 3rd. gen. except bluetooth module which interfere with my iphone from time to time-kzfaq.info/get/bejne/g5eBfdli1rSXh4k.html Unfortunately few months my original hybrid battery has at least one suspicious cycle from time to time which charge icon on dashboard up to 100% instead of 80%. Last week I noticed that one cycle charged hybrid battery up to 100% day by day during the 8h drive. Any idea what is going on?

На таком маленьком пробеге , уже вскрываете батарею ...

Bro you just made me saving thousands of dollars not to ever get a hybrid vehicle

Se puede usar pasta térmica de esas que usan los chips gráficos de las playstation?? Si uso pasta térmica en mis baterías híbridas seria buena o mala idea ?

GreenTec Auto → Gets HV Hybrid Battery Pack Replacement Done! New Life for an Old Horse Bingo, Bango, Bongo ♩ ♪ ♫ ♬ ♭ ♮ ♯ 🎼 🎵 Music for my Prius. My 2012 Toyota Prius v HV hybrid battery finally began failing a few weeks ago after ten years of use and 118,000 miles. Right on schedule for its age and mileage. Confirmed its state of unhealthiness with check engine light and the battery error codes of POA80 “Hybrid Battery Pack Deterioration” and POA7F “Hybrid Battery Pack Control Module” … After researching my options, i.e., a re-manufactured battery pack with recycled cells from donor hybrid batteries with nominal capacity of 4.5 ampere hours, I opted to invest the extra cost in a high-capacity 6.5 ampere hour HV Hybrid Battery Pack with “NEW” cells in each of the modules which compromise the pack. Glad I did as, unlike all the local re-builders that only sell the so-called reconditioned packs, which claim to include re-balancing of the cells within the modules, I wanted the 48 Month Warranty that accompanied purchase of the high-capacity 6.5 ampere-hour capacity HV Hybrid Battery Pack with “NEW” cells from GreenTec Auto ... Fast forward to the day of the scheduled physical installation at the area GreenTec Auto shop located in Phoenix, Arizona; which was scheduled within hours of my placing the order … I was contacted by a cellphone call from the Arizona area Technical Manager, Michael Ramirez who scheduled my installation at the local shop. On the day of the install I was greeted by Michael and Steve Hodgson, Technical Assistant. To my astonishment, these two men removed my old failing hybrid battery pack and installed the new HV hybrid battery pack within 30-40 minutes start to finish. Totally amazing ... Team Work in action! It’s refreshing to see such efficiency and professionalism. I’m sure glad that I made the positive decision to make my HV Hybrid Battery Pack purchase with GreenTec Auto. This young growing company has set the standard for Hybrid Battery Pack replacement! Highly Recommend … Five Stars ★★★★★
