Extremely Helpful,At the workshop where I work ,I am trying to be ahead of the curve by learning everything I can about Hybrid cars,I learned a lot from your videos.

I bought a Tenergy T180 some time ago but wasn't sure how to use it to recharge my hybrid cells. Your video was extremely helpful. I recharged my first cell today. Thank you for posting!!

Ive been using other chargers and methods (you can see some of them on my videos) but really wanted to upgrade to a charger with automatic functions like this one with 4X capabilities. The problem is, apparently everyone else wants the 4X chargers too so they are constantly out of stock. This seems to have all the automatic charge+discharge cycle capabilities I would want I can just buy multiple chargers and plug them into a power strip. Thanks for sharing your great step by step instructions for the settings so I dont have to try and figure out another new charger with chinese instructions. I will certainly use your affiliate link, you more than earned the tiny commission amazon gives. I will give ya a shout out in my first video featuring the T180.

Really, really appreciate all the work you put in these videos. I had to wire a terminal connector to leads that I could bolt to battery to keep from smoking the thinner wire used on the alligator clip leads. Thank you!

As everyone else has said, thank you very much for your informative and helpful videos. Question and problem: I have been using the Tenergy T180 to recondition my 2006 Prius HV battery modules, one at a time, exactly how you instruct in this video. I used the exact same settings. Everything was going great until block 7, then for some reason when I was taking one of the clips off (I don't know whether positive or negative), there was a spark from, I assume, it touching something. When I attached the clips to the next module & tried to start the T180, the display came up with "ERROR, process interrupted". It says and does the same thing with any other module I attach the clips to. I just called the Tenergy company and asked them about it to see if there's a way to reset the T180. I told them about the error display and they said that it is something internal that has gone wrong, and there is no way to reset it. The representative asked what I had been using the T180 for and I told him to recondition my Prius HV battery modules, one at a time. They said it was not "heavy duty enough for that", and that it wasn't built to recondition Prius batteries. And so in essence, their 12 month warranty might not cover this (I have only had the T180 about 1 month.) Whaaaat? Have you or anyone had this same kind of error code? What did you do about it? What are your thoughts about the T180 not being heavy duty enough to recondition each module? (The company rep. that I talked to said that the discharging puts too much strain on the T180.)

Very useful, thanks you. My charger arrived today and I pulled and opened my prius battery. Getting ready to cycle some cells.

Oh, pretty cool device! Thanks for uploading!

I had my settings correct. Thanks nice to have conformation.

Thanks for making such great videos! I just ordered two Tenergy T180's plus the test leads using your Amazon link.

I bought this charger. It works okay. I contacted the manufacture and they said the charger can go up to 5amps discharge but most likely on a 7.2 volt battery it will not draw 5amps. Mine was only pulling 2.1amps. Also the computer software is not available at this time as they haven't made the software yet.

Can't find which video, if any, that show the charge settings for balancing the whole pack. I've got a bunch of modules around 7.3v after doing cycles and need to balance them. Trying to use the solder method in parallel but not sure about the charge settings. Any help is greatly appreciated! 🙏

@H-EV Tech Thank you for the great videos on this subject. I'm reconditioning a highlander/rx400h battery and I started with the worst module as determined by the load test (lost 7.54V). The capacity is starting to increase: 5052ah on 1st D-chrg, then 5198ah on D-chrg 2. I'm not hopeful that this module will come back, but here is my question for you: If I get a module to come back from the dead, what is the expectation that it will be OK for use in the pack going forward? What caused the modules to fail in the first place? Heat? I guess I'm wondering what is considered a safe module to use?

Thank you for settings.

Thank you so much for sharing your knowledge! What I don't get is how you used your T180 charging the pack as a whole while all modules where connected parallel through the solder wire. I assume you used the Charge mode for this. Can you enlighten me/us what settings yo used for Capacity, Current, CHG Mode, Detla peak and Trickle curr.?

Been driving with an unbalanced battery for 2 years, and you're telling me I can fix it with my damn RC car charger!

If the cell charge voltage is 7.2-8.4 why does my final voltage show 9 volt at the end of each charge cycle? I used your specs when charging/discharging.

hey man another question this charger gives you the ability to cycle without stopping at the cut off charge capacity ? because I've tried a couple of chargers but they don't complete the 3 cycles they stops at first discharge charge.

After you cycle, how can you simply charge the battery, do you individually just charge them to 6500mah? I’m doing this on a highlander EV battery but other then the cell count that’s all that’s mostly different on these. So instead of 6 for the discharge I used 8.

Why is it that many times my t 180 /the next day /will say (esc safety)and will be stopped and will show zero under charge/cycle one/ and then under discharge it will show Va and mah,but nothing under charge?

Hi, good video how do you did a load test on those batteries?

Great video and big help. How long it took you each cell 5 times cycle? Please let me know.

Hi mate, what’s the best charger to maintain hybrid battery for Toyota Corolla hatchback hybrid 2019; ZWE211R Australian variant. Thanks

Based on some of the below comments, it seems that the charging/discharging cycles should either allow for more of a break in between charging or perhaps a fan should be set up to keep the individual cells cool during the process. What do you observe as far as temperature is concerned on each cell? What is the max temp a cell should see before damage occurs? Would it help to put a temperature sensor in each cell to monitor the temperature during charging? Have you done this, and If so, please advise your technique. Thank you.

Hello, do you add this directly to the battery + and - terminals of the pack or do you use it directly to each battery ?

Hi, I have prius c and I tested my hybrid battery cells, they were showing 13,45-13,75. Mechanic said it is very bad and soon car will display Check and battery cells will start to die. Can reconditioning help? And if so how long can they last? Thank you

So why does the first line on the Amazon site for this charger say "NOT Intended for charging/discharging hybrid car batteries or Large commercial batteries?" One of the entries specifically mentioned "Prius" batteries.

Great video. I will attempt to condition my battery soon. How many modules can you charge/discharge at a time? Thanks for great information

I was reading that NiMH isn't particularity a fire hazard. Did you have it running while not home?

Hi, great video. I want to ask you why you have to discharge while recharging the module? Isn't it a good idea to just find the voltage of other modules and charge them to the highest charged module so they all be balanced? Thanks

Thank you Approximatively, how much in % the battery is reconditionned with this method

Shouldn't it be Discharge then charge?

Thanks COOP ...

Thank you for the video. I'm have the T180, used cycle, set the charge current to 6.5A. When charging I noticed the voltage went up to 9.27 Volts. Is that something to be concerned with? What is the maximum voltage we should see when charging. Thank you.

@H-EV Tech Thanks for the informative video. I have subscribed to your channel. Is there a way to attach more chargers to this setup & view the charge/discharge curve or info live on a PC screen. Can you also install external load to these chargers to discharge the batteries more quickly? I was thinking of attaching all the modules to a grid charger & also to a large load like an oil heater for discharge. Only issue is, I cannot find a battery analyser to attach to every module to get the battery charge/discharge live data. Do you know where I can find a battery analyser for all the modules? Thanks again for the great content

What about leaving every two (of 28) blades connected, and reconditioning them as 14 blocks? The Tenergy T180 can handle 16 NiMH cells. Each block has 12 (2 x 6 per blade). Wouldn't that simply cut the time in half?

I really appreciate your informative videos. I purchased this T180 charger recently. I have been testing the cells on one of my three defunct second generation Prius battery packs. I have set the charger up with exactly the parameters you specified. Not sure what I’m doing wrong. The voltages on all but one cell were within normal limits to begin with. When I put the charger on, most of the time I get a reasonable 4 to 5000 mA reading on the first charging cycle with a decreased discharge Milli amperage. Subsequent charge cycles read between 50 and 150 mAh of charge and discharge. Any suggestions? You might save it all these cells are bad however I find it hard to believe that all 10 of the 28 cells I have tested in this battery have gone awry. Thanks

I have a question when you do Charge - Dischrage do you charge it again to finally put it in the car or leave it discharged? and I saw the balancing video when you connect all Positive and Negative do you attach it to T180 or does by itself and how long do you do it. can you please explain the process?

On similar devices, most of them indicate 7500 milliamperes for capacity cat off, on similar batteries, and why, if you can tell us ?

Thanks for posting this video, I want to start rebuilding my own batteries but I think I want to go faster I am deciding between the ev peak cq3 and the hitech 44254 since you have some knowledge about this which one would you choose, another question is pretty interesting you choose high amps for charge in the prius chat forum they recommend to go with low amps like 2 or 3 amps since I don't know much about this why you decide to choose this.

Hello, can I charge Hyundai sonata cell? It’s 8 pack in one cell and about 28 volts. Total 9 cell (72 sealed battery)

Great video! One question is how can I see what each charge/discharge cycle is? Does it record so you can see at the end of the 5x cycles? Thanks

What about charging the entire battery with all modules in series?

How many battery Cell will this charge at one time and how long? Also, how about 12 V batteries while they charge that too??

just purchased due to your video. I have an 08 Prius that has 218k and the battery seems fine still, but this might just help my hybrid batteries eek out a few more thousand miles. Does this work for the 12volt battery I just purchased? It's been sitting uninstalled in my car for a week, and I figure I can maybe top it off before installing? Thanks for the video! Extremely helpful!

Help! Great video and info however, I am using the T180 now and the voltage on charging is going as high as 9V ! Is this okay? I did not see you mention anything about the voltage and I did not see your display while charging or discharging. Anything you can add would be most appreciated. I don't see any way to limit the voltage and I pulled the plug at 9V. Also, I think the mAh would be skewed starting from 8.5 or 9v. What do you think?

o Was only 1 h? per cycle that is quick, I have the CQ3 and it take waaaay longer then that for each cycle, I am doing something wrong or it's just my charger? would be great if you could review the CQ3 charger :)

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.

So once the 3-5 hour cycle is done and the module has been reconditioned...what next? Check the voltage and consider that the new value?

So I bought 2 of these and frankly I would not do it again. I set up the charge-discharge cycle to end the discharge at 6 volts. Neither of my T180s will go down to 6 volts on the discharge. They always stop somewhere in the low 7s. I have a couple year old Revlonix Powerlab8, that I used for bottom balancing LIPO4 batteries but I could not remember how to set up a custom profile. However, I do remember that when I set it to discharge a cell down to 2.65 volts, that is exactly where it stopped the discharge cycle. I would not recommend the Tenergy T180 for proper reconditioning of the Prius cells. Doing the process helps but unless you can dump all the energy down to the lowest level, the memory effect remains.

Ok I must be doing something wrong. I did the same settings as you on the cycle mode with a 2006 Prius battery I have tried two modules now and both have swelled up bigger. What a’m I doing wrong?

Despite my best efforts, I feel like I am doing something wrong. Every single one of these units is showing a capacity of right around 300-350mah. No, not 3500.... 350. This is only on charge. On discharge it shows 0. At first I thought I had things connected wrong. I finally hard soldered the alligator clip wires to the "octopus cable" leads just to be sure that the connection was sound. Any thoughts on what the heck it could be? I was thinking that it could be too small a gauge on the alligator clip wire, but I purchased the exact cables you had shared in another video off of Amazon.

On the T-180 that I tried with, the voltage reported/sensed on the T-180 is off by quite a bit compared with taking the voltage right at the battery - difference is greatest with more charge/discharge amps specified. For instance. I put a multi-meter on the same terminals as the T180 and when discharging at 3 amps, the voltage difference is as much 0.30v, so a discharge cutoff at 6.00v is actually 6.3v. If I decrease the discharge to voltage to 0.1 amp, the voltage difference is negligible - but that would take forever. So, one could I suppose change the discharge target voltage to 5.7v instead, but that seems risky. When charging, it is the same thing, except T-180 shows higher voltage that the multi-meter. Anyone showing this as well?

Hi there nice video and I do have one of these chargers.. what I don't understand is unless you're monitoring the discharge cycle to see what your amp hour capacity is it does not save that information I thought that this unit had memory and saved the cycles, based on your inputs to your spreadsheet...so when you put your figures of each cycle into your spreadsheet were you monitoring this the whole time even though it takes hours and hours... My question is how did you know what your discharge amp hour capacity was for each one since the cycle times seem to vary... Or is this related to having to leave the selection highlighted on the (cycle amount of times mode) example 5 times cycle for used batteries... Thank you

so you charge module by module no the whole battery

A smart charger isn't going to discharge it nearly enough or properly to bottom balance it top balancing with the balancing wires sure

i haven't tried this but an idea. If you hook up 7 battires parallel and set the capacity 6500 times 7=45,500. This way you can charge/discharge 7 battries at a times. What do you think? Let me know before i blew up something like a mad professor. I think max spec for capacity is 50,000 for this device.

Awesome. IDK what this is about but comment and likes for algorithm

Can you shipping it to Australia?

I've read that the benefits of reconditioning are quite fleeting, and long-term, the reconditioned battery is barely better than it was before. Is that what you have seen?

Ok so I called the tenergy company and I asked, when its in cycling and we see "{STAGE CC}" that means its in Charge Capacity and the other after it switch to {'STAGE DC} that means its in Discharge Capacity cycle mode.... lol...nothing to worry about.

After doing this for the last 2 weeks, I can say, this specific charger does not work on "Cycle" mode. It just ignores your settings and decides to stop discharging seemingly randomly. Charging and discharging manually works fine. It's just going to take forever.

Thanks for the help, I'm following your guide now. But one thing worth mentioning - the test leads you link to are junk. Extremely thin wire, I wouldn't use them.

Welcome to the world of novice prius battery charging. If you follow these instructions on individual cells with no temperature monitoring and no external cooling . The outcome will be cooked cells. A prius only uses the cells at 40%-70% region during normal operation of the hybrid vehicle. This obviously never fully discharges or charges a cell for good reason it will quickly kill the cells. A property maintained cleaned battery is capable of lasting the predicted 21-23 life of an average Toyota . Cycling old cells in this manor ( 5 cycles) will generate too much excess heat and irrevocably damage most cells or at the very least start the process which will then kill the battery when in the car. Reason being you do not ever treat a prius cell like a standard nimh cell for a toy or model. These cells are intended to max out the cells and kill then in 100 cycles . A prius can cycle the nimh that many times in a day ( 40/70 DOD RULE ) not 0/100 DOD AS ABOVE. The difficulty with these cells is detecting the vdelta component of the cell at full charge which it is not designed todo in reality ( 70% SOC max ) . The cell needs to be charged at least 1C in order to successfully detect the small
