Hello, for hybrid or nimh batteries to work for many years, they require passive and permanent balancing due to their low cell tension, they will not be the same. This is solved by connecting a shunt zener diode with its current limiting resistor. It balances all the cells at the same voltage. It is not perfect and a small percentage of capacity is lost, but it is better than a dead battery after 3 years. This method is highly effective, reliable and easy to integrate, achieving triple the useful life of a battery.

Thank you for this very informative video. It's fantastic. I have One question. Since little more than 2 years has passed since you did this operation. How is the status for your hybrid battery today? I have a prius Gen 3. When using "DR PRIUS APP" it says that my status is 47% at the moment. This is after i have evened out the modules. In Juli 2020 i measured 65%. So i was little bit surprised getting that low rate after doing this even-out-operation. I did not balance the modules. i'll guess that i just can't skip this procedure.

You can play with voltages and chargers all you want but you need to measure internal resistance. Save yourself hours with meters and chargers and get Dr. Prius and get voltage and more important, Internal Resistance. The Pros use Dr. Prius and not Torque Pro. Also, you can buy brand new modules from www.autobeyours.com for $80.00. Stay away from "reconditioned" or "used" modules on E-Bay as they won't tell you the date of manufacture (Yes, there is a date code on each module and they know it). So you can end up buying modules older than your own. If you have a failing battery pack, don't go the dealer and hand over $3400. Don't buy a reconditioned pack. Either trade the old modules for new Panasonics at the dealer for $1950 OR call some junkyards and buy a used late model battery pack. The pack in my 2005 was dying and I was tired of playing Whack-A-Mole with used modules from E-Bay. One seller even sent me modules with scratched out date codes. Anyone can buy a 2004 pack for nothing and sell you old shitty modules. So I searched the junkyard sites and a local one had a 2014 pack with low mileage for $850. I moved up 9 years and I'll be good for many years with no worries. Don't waste time replacing and testing because all your modules will fail one by one.

@igorkadulenkov How is your battery 3-4 years later? I followed your steps (except I didn't match internal resistances in new blocks by the repaired/replaced modules very scientifically) and got errors that Dr Prius (the actual guy, Jack!) suggested mean either resistance in the orange harness (replace?) or a failing battery ECU (the rectangular thing wit the (dangerous) orange plug going into it. Once I reopened the battery metal cover, I could immediately see bad green/brown corrosion on the copper bus bars - much worse than the car had when I removed the battery 3 years ago - when the battery was 17 years old. I used NoAlox like you did, so I'm wondering if that was not helpful for you either? Another problem in my car is water intrusion. Though I caulked and sealed what I thought were all the rear area leaks, it appears there are more of them than I thought - and shockingly I can day light through the driver side rear wheel well area above a few inches above the rear strut! So when driven in rainy conditions, I assume quite a bit of tire-spun water was getting in to the area close to the battery. I will be using some Rust Reformer and Bondo or something on that, but that might account for some of my corrosion. However, I wondered if others had bad corrosion after it. As for the condition of the HV Battery, Dr Prius (the app) says the battery itself is at 88% (OK/Good) after 3 years, though I've not dug into the module checking (grrr, not looking forward to that weeks long process again) yet...

Igor, you’ve done the world a great service with this video. Thank you! But now that you’ve educated us on how to recondition our batteries; that it isn’t just a matter of one quick test on the cells before replacing one or two of them-and with the recommended Turnigy Charger now backordered for a month or so, I find myself in the middle of a lengthy process I wasn’t prepared for. So here’s my question: With the 1-cell charger I now have, my project looks to not be complete for a good month or more; when the Turnigy Charger would finally be available. So, would you recommend I just replace the worst of my cells right now, reinstall the battery, and then start the project anew when the Turnigy Charger comes in next month, or recondition just one cell a day for the next twenty-eight? And, are there any procedural changes to take, given the long timeline? Again, great video; great research you share! Thank you! I look forward to your reply.

Hello Jim, thanks for your feedback! For your question: i think it should be fine to just throw in a replacement module, if you already know which module had failed. This is a short term solution, performed by many questionable battery repair companies and it usually works just fine for a year or so until another module fails. If you do this, you need to level the voltage in replacement module to the rest of the pack. If you planning this as a temporary solution for a month or two, this sounds like a lot of work - removing and reinstalling the battery twice. Maybe it's better to get 3-4 more chargers from what is available? hobbyking.com/en_us/batteries-chargers/chargers.html?wrh=2%2C3&stock=1 I think some people were using IMAX B6 50W which is 25$ each. There is a bit of discussion about IMAX B6 on PriusChat forums. TURNIGY REAKTOR is really good, but it starts at 50$. You can also get Turnigy double chargers for 100$. You could also sell them on eBay later, once you've done with reconditioning.

Igor Kadulenkov Thank you, Igor. At your suggestion, I look to get enough chargers to recondition seven cells at a time, and then probably resell the chargers. Easier to resell, though, if a power supply is included, so that may limit me to buying chargers with included power supplies. Crazy that power supplies aren’t more commonly included, or at least offered as a simple add-on. But, thanks again, Igor! I love the resell idea.

In your section where you give the links to the equipment used I would discard the trunigy 4x6 for some other charger. They did away the capacity results after doing the discharge/charge cycle. I thought I was doing something wrong and finally reached out. Turns out they updated the firmware on this unit and it no longer gives you the capacity report on each charge/discharge session at the end. Total crap imho, as I will now be returning the unit as we bought it for this vital function that is no longer available due to their firmware update. I mean you can watch it in live action and try to catch it when it switches cycles, but some sessions last up to eight hours and I don’t really feel like sitting there staring at this unit. Any suggestions on what other charger can perform this would be appropriated.

Dear Igor, I wanted to thank you for your video which along with the Prius Chat threads enabled me to do a good job re-balancing all the modules in our 2006 Prius. I only had to replace one cell! She's running great now with no Triangle of Death nor any codes whatsoever. I did forget to push down the handle on the orange service plug which resulted in the car not going into drive, reverse or even the motor starting. So I wanted to emphasize this step for others considering this process. BTW, I wanted to mention that I used the Hi-Tec X4 AC Pro AC/DC 4 Port Multicharger which performed flawlessly and didn't require any external power supplies to keep up with the load.

Bravo to Igor, Prius Chat, and all the comments here. I have a few questions for anyone/Igor. I have 2005 Prius and while I could do this and it would be fun, I might prefer to buy a refurb battery and put it in myself. Questions: 1)I’m in NY ( Long Island) does anyone recommend a place that has refurbed batteries or will handle the install as well? 2)if I were to buy a refurbed battery or a full install, what can I ask them to show me the battery strength or know if they took all the proper steps? 3)The battery is 80lbs, does anyone know if ebay or ppl ship this item? 4)Does anyone have any tips/experience in buying a stand alone refurb battery OR tips/thoughts on a person/company that HAS done work for you? 5)Is there any other tips on how I might be able to get someone just to do the removal/install parts if I provided the battery? 6)Are there sites other than ebay to find a battery? if it ships and if I could verify any aspect of that battery before purchase 7)I love my Prius as much as anyone and I’m looking to buy a gen 3. Any tips on that in the north east or via auction? Again, thanks to Igor and everyone. The Prius community is awesome and in a weird way most of us love the Prius line for a lot of the same reasons. Maybe it’s low maintenance, the environment, or just sweet gas mileage. I can’t wait to jump to a slightly nicer gen 3. Thx so much

It's up to you, but in general - the lower the better, as it will put less stress on the module, but it will take longer to complete 1 cycle. The higher the current, the more likely it is that the module will overheat and expand. I started at 3A and then increased to 5A(or 4A, not sure). I think, the most gentle charge rate would be 0.1 * 6.5A = 0.65A. I don't think it will affect the final capacity.

May I? As long as they can go up to 16.8, little more often...14.5v like Lead will be ok, but no discharge lower than 1v/cell, that's minimum 12v limit! If you can set your solar charger to 1.4v/cell will be even better!

Some thoughts for folks who just watched this video - this was what I did about a month ago before completing my HV battery work: This is a great video but you can improve on certain little bits of it - and learn details from other good videos and websites. For example, remove the rails/white blocks from the HV battery case and do your cycle rebalancing outside of the case. At the end, after you've made your module replacements, switches and swaps, you can easily bolt it back together on your bench - and then put it into the HV case - no struggling and squeezing - that might potentially break the tabs on the white blocks. Another thing: mentioned by Igor, balance all your cells by tying + and - together (thus putting the modules all in parallel for 24 hrs., after you bring their final voltages to within .05v of each other. There's an excellent HV battery assembly/disassembly video set by user Eletronautomotive, who do HV battery reconditioning professionally and made their video to help their customers remove and install the packs sent out to them.

It is not a good idea to do your module cycling outside the case , in fact it is a very bad one , even with hobby chargers and plenty of ventilation the battery modules will swell and if not compressed they can and will expand. By leaving them inside the case this prevents any sort of expansion , if you are worried about the tabs on the white blocks breaking , you can always use ratchet bar clamps to relieve some of the pressure off the tabs. Also 'balancing' the cells by voltage does absolutely nothing for the battery , I am not sure how this idea got spread , but the only balancing that should be done should be dictated by the capacity , internal resistance and voltage under load, if the all of these parameters are closely matched then the voltage should naturally follow. This is like treating the symptoms instead of the disease.

Hi Igor I just wanted to pass and say THANK YOU SO MUCH. You have been an amazing help on the process of refurbishing my battery and your quick response to every question I had in the process. I had 0% of understand the hybrid battery and even so I have plenty of family members that are mechanics nobody knew how to help either. I will recommend this video as much as I can to every Hybrid owner I know to help your channel grow and if there’s any other way I could help please reach out. Again thank you from the bottom of my heart sir you’re amazing in explaining and answering my tedious question. Wish you the best of luck in everything God bless 🙏🏽🙏🏽 And for anybody doubting they can do it stop thinking that way. You can best of luck and ask my friend over here he is the best.

Hi Nicole, thanks for the feedback! It could take anywhere between 7 to 15 days, depending on how much time you have, how many modules you could be charging at once and if you enjoy working on the cars in general. The problem with refurbished batteries is that shops never do a thorough reconditioning, but just replace a module or two. So you are essentially buying yourself 1-1.5 years before it happens again. But If you spend extra time and do a quality reconditioning, it could last for years. It’s been 4 years since the video was filmed, the battery on the video is running strong.

Great video! Thanks for sharing. I have a 2 question, maybe possible tip for others. I have 3 chargers (imax rc6). In aim to save time I consider to do the following: Use chargers for charging only, discharge will be done with the hb4 bulbs (3) as mentioned. In that way I can save the time of the disharge. Question 1: any difference when discharging with bulb, comparing to charger usage (is it less effective?) Next thing :) , in aim to have three discharge->charge per cell: I think about doing 1 cycle on all the 28 cells, then second cycle, and eventually the third (last) , so instead of: 3 cycles * 28 cells * 1 iteration, I'll have: 1 cycle * 28 cells * 3 iterations. In that way I hope to prevent over hit of the cells (letting each one to" rest" befor next discharge-> charge). Question 2: Is it effective, good idea? Thanks again! Starting tomorrow 😀

@IgorKadulenkov

@Ahmed Zakaria Hello Ahmed, I can only speak from my experience with this rebuild. In my case most of the modules had recovered by 6th cycle. And then there were a few stubborn modules, that would only grow by 150-200 mAh with every cycle. I ended up replacing those. I would say, just look at overall condition of your pack. If all of your modules are like that, and assuming you using the same charging settings that i did, then I would just keep them or try to get a used HV battery in a better condition. If there are just a few of them that stand out being the weakest, i would definitely replace them.

Igor, would it be possible to charge and discharge all blocks simultaneously with lower charging amps? In other words, in your opinion, would this be possible and not overheat the blocks? My thought is to use 7 Turnigy Quads with 7 HP power supplies (or the equivalent)?
@IgorKadulenkov
5 жыл бұрын
Hi John, I think it is possible. The best charging rate would be 0.75 amps for a module. At this rate they should not overheat or expand. You could try to raise it higher, maybe to 1.5-2 amps and run a single module to try it. I would still discharge at highest rate your charger can do (usually 2-3 amps). Also, if you going to use the same power supply as I did, you will probably need only one. It can handle 40-45 amps. It should handle all blocks simultaneously 1.5amps X 28 = 42

Hi Igor, very helpful video, thank you for your efforts. I am having some problems - I am using an IMAX B6 charger and did all the settings as per your instructions but I just can not seem to get through a full set of cycles and get any results from the device. I left the IMAX B6 to charge one cell for about 9-10 hours yesterday and the B6 had just frozen its screen. The battery cell had gotten warm and swollen, I turned everything off and the next day the cell had shrank. How do I use the IMAX B6 correctly?
@cawag98
3 жыл бұрын
The B6 chargers are known to often be fakes of the actual B6s, themselves copies of earlier chargers. I got one from a hobbyist and it was complete junk. I got another from Ebay new for $20 shipped, knowing it was a fake of a copy. It turned out to be mostly useful- the DSC level was 1.5A (higher than my multiport Turnigy charger DSC rate) but the darn thing refused to do more than one DSC->CHG cycle. If you're going to use these chargers you need to become familiar with the strange menus/button presses in them. Some of the settings are under User Settings menu and some of the settings are under the Battery [Nimh] menu. If you can buy a multiport charger that allows high rate DSC values. The Turnigy 4x6s helped me a lot, but you wait FOREVER with only .5 DSC rate (although it claims up to 3A...)

I caused a spark from just removing the orange bus bar assembly after removing all the nuts. Be careful. In this case, no so much because the battery is outside the car and not connected by the big orange cables. Otherwise, very good video.
