I've seen videos by hybrid techs that suggest balancing the modules before installing them. This is done by stacking the modules with all of the positive terminals on one side and all of the negative terminals on the other.. Then run a conductive bar across all of the positive terminals and another across the negative terminals. This makes them all in parallel. Leave them like this for a day and all modules will be balanced with exactly the same voltage. If they aren't balanced they won't charge equally.
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.
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.
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. 👍🏼
No your wrong. Get your nomenclature right. You are calling shit the wrong thing and terms are not interchangable. Cells are not numbered. It goes in order of size battery, blocks (made of two modules), modules (made of 6 cells), and cells which you will never see or deal with so it's a moot point to number them. But you can if you are anal retentive and want to. Oh and I hate to tell you all especially you creator of this garbage video but numbering is completely arbitrary and is strictly according to whatever your reference is so technically all you fuckers are wrong. You could number them randomly and be correct if that's the reference! Why you idiots seem to not comprehend is your program has one numbering scheme, a different program will likely have another, a tech sheet will be different, and they all probably don't go according to Toyotas numbering which should be the gold standard concerning this specific battery if you are habitually retarded and are so adamant on concerning yourself with something so none relevant to everybody instead of focusing on the problem and task at hand. Which you obviously are! I'm talking to you video creator! I'm seriously considering calling this trolling since it almost seems designed to confuse and misdirect those seeking actual knowledge.
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.
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.
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...
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.
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?
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
Just want to jump on ur comments here..if cells are found to be no good u cant just replace it and put everything back? Is it neccessary to balance? If so how do u perform a balance and with what? Help if u can.. Thanks
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 ?
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
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

It is a good one off product for learning how to recondition batteries at home minus the headache. Ive heard some interesting things about it and my buddy got excellent results with it.
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?
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.
Yes it's called Torque Pro, and then it's kind of tricky getting the Prius packs installed to view the cells individual voltage readings. But you can Google it, and figure it out
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.
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?
If you put a resistive load of about one ohm and 10 watts power capacity across a module it will discharge at 7 Watts which would give you 7 amps discharge. You can time that and take the average between 6 and 7 amps. It would still take you a full hour to discharge a good module through 1 ohm power load. That's because it has 6.2 amp-hour capacity at about 7.2v average, so with 1 ohm load you have average 7 amps flow (7volts/1 ohm= 7 amps).
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
The car is still driving today with no battery problems whatsoever. My brother drives the car and has put about 40k miles on it since he bought it. Mostly highway
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.
Personally I would set a timer and discharge each cell (with a headlight bulb or dc motor) and see which ones discharge the fastest. The ones that discharge fastest will be the bad ones. You probably have one or two that will discharge extremely fast, replace those & equalize all the voltages. Wait a day and then top off each cells voltage so that it's perfectly equal before reinstallation. Any variance will throw the computer into failed mode. You can safely discharge them each down to 0.8 volts per cell
Thanks for the timely reply. When doing deep discharge/charge and checking mAh for the batteries on the B2AC what settings do you use for Discharge / Charge. I have now 8 of these to complete the job and are discharging. I see Battery Reconditioning threads from many that do the packs and they go down to .8 then .6 then .5. If we go this route I mark changes in mAh between cycles. Again question is what should be discharge and charge voltage C Level, i used C=0.2 which is 1.3A. Lower or higher for NiMH Battery Panasonic 1.2V 6500mAh.
I would say anything below 13 volts, throw it out. You want all of your cells to be around 15 - 16 volts holding. And as you drive they will fluctuate from around 13 - 19 volts, and hold around the mid 15's
John Caleb Warren when driving, I got all the blocks in mid 15th. With all that I still get the code POA080- replace the hybrid battery pack. What could that mean ? Could that be just aux 14v battery ? Can that generate this trouble code ?
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
Dmitry Kim using an obd2 car connector preferably not cheap ones and wireless,also there’s many apps for example dr.prius/dr.hybrid. On that app there’s always gonna show a low graph in one of the blocks but it’s just how the app is designed all u have to make sure is that the voltages are even .btw it’s way easier and fast when you take off the bottom pan of the battery this guy made it more complicated any more questions feel free to ask I’m a tech I’m feeling nice today.
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?
I would recommend buying no less than 6, and just replace the weak cells. I believe I only ordered 3 or 4 & turned out I needed more once I had the battery apart
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?
The cells that generally go first are near the middle of the pack. This is because that is the warmest place (being boxed in by all the other cells which are also warmer than the air flowing into the housing.) However random cell failures can happen anywhere in a pack. The chemistry changes over time and none of the cells degrade at the same rate.
Essentially don't charge higher than their rated voltage, & keep amp low enough not to cause high temp/boiling/evaporating battery electrolyte. Experiment & monitor for emergency stops/unplug. -copper wires, in parallel +/- ... -7.2volt spec= 7 volt car/RV/marine battery charger. (refrigerator+charger overnight)
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
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,
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!!
I use AquaNine with Wifi. On my Adroid phone, I find I have to delete my Wifi connection to the router, and then connect to ODB2 device. Go slow, allow the device to connect. It says connected with no Wifi. After fiddling for about 15 minutes, I can get it to connect, and then it seems to work.
He is using torque pro. I'd recommend Dr prius/hybrid . Dr prius/hybrid can test your hybrid battery and give you a battery life estimate and do a bunch more
Funny thing, Two day ago, my tech buddy from Toyota Justus’s showed me the tech settings in the head unit that. Gave me all the info I needed through the car itself. Hehehe
The imax b6 charger could only draw a max discharge of 1amp, per charger I believe. So the reason I used the DC motor was just to speed up the process. It would have taken forever just using the chargers alone. I think I used a small headlight bulb to drain some of them too, in addition to the DC motor
interesting points ,if anyone else needs to find out about lead acid battery reconditioning guide try t.co/YpdloYO92F ? Ive heard some decent things about it and my partner got cool results with it.?
The answer is the largest charge the smallest cell can handle. So if your system weakest cell can handle 7.6 volts then your system should eb balanced for that level.
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?
If it's within the same model year it should work. I would recommend just purchasing the cheapest reconditioned battery on amazon with a warranty and installing it yourself
John Caleb Warren thank you kindly for answering. I went to a shop and was told they would replace all my modules with new generation ones. I'm confused on that. Okay i already have the battery apart just trying to order the right one but I am confused to which battery I need. Can you explain a little more on the battery you were commenting about? Like do you mean I have to purchase a battery with my trucks year? Or how do I go about it? I was just gonna order one that looked similar but I was told that was not the right way to do it. Thanks
My hybrid battery failed yesterday. I called Toyota of America this morning. They took all my info and said that they didn't sell any parts at their headquarter and referred me to contact the local Toyota dealers directly. I did speak to the dealer b4 calling them and wad told 5k for a new pack. Please advise. Thank you.
If its your first time to have a problem with your hybrid batterys its most likely a single cell with low voltage. Higher mileage could be mulitple as in the video. A single cell can be found for around $30-40 on ebay/amazon. craiglist.com (nc) has guys that will change them out for $500-$750 fyi.
My advice having messed with half a dozen or more of these cars, would be just to buy a reconditioned battery pack with a warranty for around a grand, and replace it yourself. It's not worth the hassle for trying to recondition them without a lot of experience. It's easy enough just to pull the back trim and R&R the battery. That way you don't have to mess with the computer or Electronics. And that will probably get you by for at least 3 or 4 more years without any problems
Call several dealers in your area, I ended up just going with a new OE battery from toyota for 2k since I plan on keeping the car for as long as possible. Dealership prices varied from 2k to more than 4k just for the battery, installation prices varied as well.
I would say for actual Hands-On work, about 8 hours but a lot of it is broken up over days and nights while charging. It really is an easy process looking back on it. And the car/battery is still holding out great!
Sir I'm getting alot of errors on my crown hybrid 2AR-FSE similar engine to lexus gs300h i got the error code translated and it's telling me to replace my hybrid battery. Can u give me some tips on what should i do first off? I don't want to spend $2.5k on a new battery. Plus toyota says these batteries last for minmum 300000kms max 500000kms. My car only has 120000 odo kms. Any help would be great. Thanks
My advice would be to buy a reconditioned battery pack w/ warranty from Amazon or Ebay from a good seller that has great reviews. That is your best bet if you want to avoid all the time of doing it yourself. Removing & replacing the battery pack is pretty easy though, just a few hours of trim. The computer will automatically detect the new battery & work just fine, if your wondering. That's your best bet for the cheapest price
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.
Yeah it took about 2 or 3 days, off & on. The car is still doing great to this day. My brother has put about 40k miles on it since the battery reconditioning
Because they are NOT lithium ion batteries. They ARE NiMH in the 1st, 2nd and & 3rd gen Prius. You must be thinking of the newer fourth-generation Prius, because 2015 & newer started using lithium batteries
what is the name of software on Samsung mobile? how does it work? via Bluetooth? I have a Lexus ct200h and would like to connect to the "battery controller" to the real-time picture
I've seen videos by hybrid techs that suggest balancing the modules before installing them. This is done by stacking the modules with all of the positive terminals on one side and all of the negative terminals on the other.. Then run a conductive bar across all of the positive terminals and another across the negative terminals. This makes them all in parallel. Leave them like this for a day and all modules will be balanced with exactly the same voltage. If they aren't balanced they won't charge equally.

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?
If you put a resistive load of about one ohm and 10 watts power capacity across a module it will discharge at 7 Watts which would give you 7 amps discharge. You can time that and take the average between 6 and 7 amps. It would still take you a full hour to discharge a good module through 1 ohm power load. That's because it has 6.2 amp-hour capacity at about 7.2v average, so with 1 ohm load you have average 7 amps flow (7volts/1 ohm= 7 amps).
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

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.
Personally I would set a timer and discharge each cell (with a headlight bulb or dc motor) and see which ones discharge the fastest. The ones that discharge fastest will be the bad ones. You probably have one or two that will discharge extremely fast, replace those & equalize all the voltages. Wait a day and then top off each cells voltage so that it's perfectly equal before reinstallation. Any variance will throw the computer into failed mode.
You can safely discharge them each down to 0.8 volts per cell
Thanks for the timely reply. When doing deep discharge/charge and checking mAh for the batteries on the B2AC what settings do you use for Discharge / Charge. I have now 8 of these to complete the job and are discharging.
I see Battery Reconditioning threads from many that do the packs and they go down to .8 then .6 then .5. If we go this route I mark changes in mAh between cycles.
Again question is what should be discharge and charge voltage C Level, i used C=0.2 which is 1.3A. Lower or higher for NiMH Battery Panasonic 1.2V 6500mAh.
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?
I would say anything below 13 volts, throw it out. You want all of your cells to be around 15 - 16 volts holding. And as you drive they will fluctuate from around 13 - 19 volts, and hold around the mid 15's
John Caleb Warren the 15-16 volts is for every pair of cells correct?
Because I’m getting 7.4-8.3 ish, for one single individual cell.
John Caleb Warren when driving, I got all the blocks in mid 15th. With all that I still get the code POA080- replace the hybrid battery pack. What could that mean ? Could that be just aux 14v battery ? Can that generate this trouble code ?
@@MrNostradamus1976 yes it can. My friend had the same issue, changed aux battery and everything is fine, its 8 months now.
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
Dmitry Kim using an obd2 car connector preferably not cheap ones and wireless,also there’s many apps for example dr.prius/dr.hybrid. On that app there’s always gonna show a low graph in one of the blocks but it’s just how the app is designed all u have to make sure is that the voltages are even .btw it’s way easier and fast when you take off the bottom pan of the battery this guy made it more complicated any more questions feel free to ask I’m a tech I’m feeling nice today.

It's been awhile since you're done I presume, is it still holding up
Thank u.very helpful
Just wondering, if the RC chargers work as dischargers as well, how come you used the DC motor to discharge at the beginning?
The DC motor helped discharge a little faster. About the best the rc charger would discharge was 1 amp, & the DC motor would draw 1.5 - 2 amps
Yes how about an update.
Have you lost any further cells?
Nope, still holding strong. My brother bought the car & he hasn't had a problem since
Looks like the cells away from the t senders aged faster, not just on both sides. Don’t you think?
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?
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!!
Traditional Japanese and Chinese read from right to left - the opposite of the west.
That 17volts could be induced or reverse leakage.
where did you he app for the battery fro your phone !!!!!! what is transmitter ????
did you notice any increase in mpg after doing this?
Yes, about 3 or 4 mpg average
Dealership told me I needed a new battery but I checked all of them there good 7.98
Is this charging method the same as when the sellers online say its "reconditioned/refurbished cell" ? and they get around around 8V also
Googling "DIY Grid Charger" may be of interest yo you. Gives you a low-cost way of balancing the entire pack all at once.
My 07Prius had big power loss. Shows dash panel light on.
Has 185k miles.
How many cells do you think I may need? Thanks
I would recommend buying no less than 6, and just replace the weak cells. I believe I only ordered 3 or 4 & turned out I needed more once I had the battery apart
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?
The cells that generally go first are near the middle of the pack. This is because that is the warmest place (being boxed in by all the other cells which are also warmer than the air flowing into the housing.) However random cell failures can happen anywhere in a pack. The chemistry changes over time and none of the cells degrade at the same rate.
Where can I get the cells I'm in Botswana?
How much shold each pair of cells charge up to is used in solar??
Essentially don't charge higher than their rated voltage, & keep amp low enough not to cause high temp/boiling/evaporating battery electrolyte. Experiment & monitor for emergency stops/unplug.
-copper wires, in parallel +/- ...
-7.2volt spec= 7 volt car/RV/marine battery charger.

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

Thanks

How long the whole process took you, and did you have to charge/discharge them all, or just the suspected ones?
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,
I am the owner of a 2010 Toyota crown hybrid 3.5 litre. there are problems with the battery. where can I source cells for my battery

what's the app you use that reads each block on your phone?
TORQUE APP
@@21boxhead
Hi
Is it torque pro ?
@@hgh6791 YEAH THE PAID VERSION
TORQUE PRO
@@21boxhead thanks
@@21boxhead How is able to see it on his phone though? I don't see a cable plugged in.
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!!
I use AquaNine with Wifi. On my Adroid phone, I find I have to delete my Wifi connection to the router, and then connect to ODB2 device. Go slow, allow the device to connect. It says connected with no Wifi. After fiddling for about 15 minutes, I can get it to connect, and then it seems to work.
What bttery tester app is that? On the smart phone?
He is using torque pro. I'd recommend Dr prius/hybrid . Dr prius/hybrid can test your hybrid battery and give you a battery life estimate and do a bunch more
Funny thing, Two day ago, my tech buddy from Toyota Justus’s showed me the tech settings in the head unit that. Gave me all the info I needed through the car itself. Hehehe
Can it test for Toyota camry hybrid
Great video. Just wondering, why did you use that motor to discharge the modules instead of that IMAX device?
The imax b6 charger could only draw a max discharge of 1amp, per charger I believe. So the reason I used the DC motor was just to speed up the process. It would have taken forever just using the chargers alone. I think I used a small headlight bulb to drain some of them too, in addition to the DC motor
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
Hi
Can you please let me know the name and model #of the scan tool you used?

nice, great job !
Can you help how to change new Toyota hybrid 2 2018 Grille shuttle motor please.
interesting points ,if anyone else needs to find out about lead acid battery reconditioning guide try t.co/YpdloYO92F ? Ive heard some decent things about it and my partner got cool results with it.?
It's probably reading like that cuz it has a leaky cell causing the triangles of death to come on with the p0aa6/612
Once you are ready to place the hybrid battery back into the prius how much should each cell be charge to?
The answer is the largest charge the smallest cell can handle. So if your system weakest cell can handle 7.6 volts then your system should eb balanced for that level.
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?
If it's within the same model year it should work. I would recommend just purchasing the cheapest reconditioned battery on amazon with a warranty and installing it yourself
John Caleb Warren thank you kindly for answering.
I went to a shop and was told they would replace all my modules with new generation ones. I'm confused on that. Okay i already have the battery apart just trying to order the right one but I am confused to which battery I need. Can you explain a little more on the battery you were commenting about? Like do you mean I have to purchase a battery with my trucks year? Or how do I go about it? I was just gonna order one that looked similar but I was told that was not the right way to do it. Thanks
My hybrid battery failed yesterday. I called Toyota of America this morning. They took all my info and said that they didn't sell any parts at their headquarter and referred me to contact the local Toyota dealers directly. I did speak to the dealer b4 calling them and wad told 5k for a new pack. Please advise. Thank you.
If its your first time to have a problem with your hybrid batterys its most likely a single cell with low voltage. Higher mileage could be mulitple as in the video. A single cell can be found for around $30-40 on ebay/amazon. craiglist.com (nc) has guys that will change them out for $500-$750 fyi.
My advice having messed with half a dozen or more of these cars, would be just to buy a reconditioned battery pack with a warranty for around a grand, and replace it yourself. It's not worth the hassle for trying to recondition them without a lot of experience. It's easy enough just to pull the back trim and R&R the battery. That way you don't have to mess with the computer or Electronics. And that will probably get you by for at least 3 or 4 more years without any problems
@@JohnCalebWarren Thank you.
Call several dealers in your area, I ended up just going with a new OE battery from toyota for 2k since I plan on keeping the car for as long as possible. Dealership prices varied from 2k to more than 4k just for the battery, installation prices varied as well.
Excellent! how long did it take you to recondition the whole pack?
I would say for actual Hands-On work, about 8 hours but a lot of it is broken up over days and nights while charging. It really is an easy process looking back on it. And the car/battery is still holding out great!
awesome!
How many chargers did you use? only 2?
@@ahmedzakaria356 actually I had 4 chargers, but I blew one up on accident. So really only 3
Sir I'm getting alot of errors on my crown hybrid 2AR-FSE similar engine to lexus gs300h i got the error code translated and it's telling me to replace my hybrid battery. Can u give me some tips on what should i do first off? I don't want to spend $2.5k on a new battery. Plus toyota says these batteries last for minmum 300000kms max 500000kms. My car only has 120000 odo kms. Any help would be great. Thanks
My advice would be to buy a reconditioned battery pack w/ warranty from Amazon or Ebay from a good seller that has great reviews. That is your best bet if you want to avoid all the time of doing it yourself. Removing & replacing the battery pack is pretty easy though, just a few hours of trim. The computer will automatically detect the new battery & work just fine, if your wondering. That's your best bet for the cheapest price
@@JohnCalebWarren i guess i'll do just that. Thanks for the reply.
the level of corrosion on those jumpers, is what killed those cells.
How about more info? What year is your specific car, where do you purchase the Prius software for voltages?
Car is a 2007 model. Phone app. for voltages is called Torque Pro
@@JohnCalebWarren Thank you!
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.
Yeah it took about 2 or 3 days, off & on. The car is still doing great to this day. My brother has put about 40k miles on it since the battery reconditioning
That's an auto-ranging fluke DMM you don't need to change the decimal place
Don't mess with the battery, if your going to do it replace every cell. Do not replace individual cells.
May I ask why not replace a cell. It would be better to get a new battery rather then replace all the cells.
Huh! The dealership quoted me $4560
Don't listen to this moron, probably works at Toyota lmao
Why are you using your chargers on NiMH settings with a lithium ion battery?
Because they are NOT lithium ion batteries. They ARE NiMH in the 1st, 2nd and & 3rd gen Prius.
You must be thinking of the newer fourth-generation Prius, because 2015 & newer started using lithium batteries
Awesome thanks!
