I was just told by the guy I bought my used cells from that a voltage test is not accurate and the only way to properly re condition a battery is to load test each individual cell after it has been charged and discharged 3 times.

You should test the NiMh batteries with load. There are not so many packs so you could connect each pack with wires to the cabin and measure the voltages when driving the car. Using very thin insulated wires makes it more safe in case of short circuit. I don’t know if service stations have a measuring jig for this as it is very reliable way to detect bad packs. There may be a computer program which measures all the voltages as a plotter. BTW, you don’t have to swap the test leads when measuring (when using a digital multimeter).

Always take the orange caps and the 8mm bolts out of each cell and check for corrosion behind the orange plate under each nut . I almost always end up cleaning up a bunch of corrosion on the 1st 2nd and 3rd generation prius battery's and camry hybrid batterys as well. In the 2nd gen prius their really bad about leaking rain water from the factory moldings at the top of where the hatch shuts in its track .also above the tail light too. You should always inspect for water trails and do a leak test on the 2nd gens because water is the #killer of these battery's. I always take the drain grommet out of the battery hole and spare tire hole if they do leak until i can confirm the leak is gone. Best of luck everyone . This is good knowledge to have considering gas vehicles will unfortunately be a thing of the past within the next 10 to 20 years and best believe the ones experienced in these hybrid cells will be making bank if they wanted to open their own shop

Usually a multimeter test works...but not always. You might have to load test the Cells individually, or take it to a shop that can Test them....still dirt cheap though!. But yeah, most people get away with a quick Meter check, swap out the Modules that are reading Lower than the rest, done deal. But like I said, it really depends....not everyone's situation is exactly the same.

What multimeter setting to use??

1 have been doing some research, it seems like you can use gen 3 cells in gen 2. But can you use gen 2 cells on gen 3. Mine is a gen 3 from 2010. Most of my cells are above 7v I have 4 that are in bad shape in the low 4v those I am going to replace for sure. However would you recommend to change anything below 7v? I have 4 other cells in 6.6. Please help :) and thank you for your video

what is the name of the testing machine hour using is that an amazon item. thanks

Only defective modules can be found via the voltage. With a capacity measurement, weak modules can also be found. These weak modules are among the first to be broken the next time. I found a 7.4 volt module with only 1800 mAh. Normally old modules (year 2007) have approx. 5500 to 6500 mAh. Here you find the way to check the capacity of your cells: kzfaq.info/get/bejne/nZt7dLOYypPKZnk.html

Can you tell me please whats the name of the tester you used

Doesn’t a bluetooth OBD scanner with phone app show excactly which cells are bad before you remove battery? Many videos show how.

So how did the car work after the repair????? Did it work run ok etc?

Lmao, when you say exploded I thought you meant you opened them up to take a look inside. But you actually mean they exploded while in use! That's pretty scary!

You should have removed the 28 battery hold down screws first than the compression block.

THANK YOU FOR YOUR VIDEO IS WHAT CAN YOU TELL ME BLOCK 9, BEGINNING TO COUNT FROM ECU (COMPUTER OR DRIVER SIDE TO PASSENGER OR THE CONTRARY, IT OR THE POSITION OF BLOCK 9? THANK YOU

How do u know wich one is bad

Did you get any error code before you did this? Did the car start? Did you get the red triangle. I'm pretty sure you lost mpg

Do you have to take off the orange plastic? To check the voltage ?

This is not the right way to test, you need to load test them. I had good readings across the board voltage wise but had cells not holding.

Hi Tamara, I use Toyota Camry 2007 Hybrid. Will any hybrid battery work for the car or how do you tell the specific battery to buy.

Can you give me the web site for alpha auto please

I just tested all my cells on a battery from a 2007 prius. 2 read 6.4, and the rest were 7.7 and 7.8. I understand that the 6.4 are too low, but are the 7.7 and 7.8 too high?

Car still good?

The 2012 camry battery can take apart the same way.

Where does the single battery purchased?

Good job DIY and save lot of $$. am wondering if there any battery test that one can quickly use to identify bad cells prior to taking the pack out?

why not replace the whole cells?

So let me get this straight. If your hybrid battery fails, it could be due to bad modules/cells? If you replace the module/cell then your battery will work? Can someone explain this because this just made since of why dealerships want to charge an arm and a leg to replace the battery.

For the viewers who have no idea about electricity (for example don't know what a multimeter is) for their safety to avoid doing anything. Let the electricians do it and pay them for their knowledge.

Can someone share a video of how to take cover off for hybrid battery?

This is hysterical. He has KZfaq instructions, eBay parts, and no shirt on while handling high voltage lithium ion cells.What can POSSIBLY go wrong? Natural selection at work folks 😉

how did it go? car still running?

below 7.5 have fault or 7.0 ?

How much does that whole thing weigh?

You better clean your fan bc that why they exploded

I already changed my battery cell but still hybrid system light on.how can I fix for that

I am not sure that is the right way to test the cells. I got an engine light which said the battery needed to be replaced. I checked the voltage by techstream software and several packs(two cells in each pack) showed a voltage around 17 volt for my Lexus. it's supposed to be above 20 volt. I removed the battery and tested the cells. All cells showed around 10.5 volts. So according to your test that is 21 volt per pack. So all cells were good according to your test but they are not. So your test does not really work.

You are only testing Resting Voltage.....which is a 50/50 gamble. You NEED to load test with a meter...which is also Not hard. What you are doing might work for a few months, or get you threw the summer.....but you're most likely going to be CHASING your tail around, just swapping out packs all the time!

Wait... Is that lead acid batteries?

Better buying battery from wrecker

here's several ideas for battery reconditioning Don't try to do this unless you are sure what you are doing - the acid can burn you Test the voltage first - there may be a dead cell which would waste your time. Check the battery fluid. Try to fully charge the battery. (I learned about these and more on Jons Mender Guide website )

There are several things for getting a good result never try to do this unless you know what you are doing - the acid can burn you check the voltage first - there may be a kaput cell which would waste your time. Check the battery fluid. attempt to fully charge the battery. (I read about these and more on Jons Mender Guide website )

YouZed lol

Omg trade it in

Very bad video and many wrong tips: You do not have to remove all modules to swap bad ones. Voltage test is not acurate. Broken nimh battery also can have high voltage but under the load it goes rapidly down causing mcu error. At the end, balancing is very needed if you add modules. They should be all connected in paralel mode for min 24h or even longer. Cleaning copper connections.

before you repair did you get the poa80 code?

Why don't you buy brand new cell? No need to spend money on used cell.

NEWSFLASH SHIRTLESS WONDER, voltage is irrelevant ! The load required to move a 2400 lb "car" is significant, potential energy is measured in each load cell by how much amperage it can produce in a symphony (unfortunately by bad design, no cell jump circuit). Potential energy is amperage where as voltage is the electron force. Physics 101. These little cells are a bad design because theyre low quality 8v compartmental cells that fatigue and reverse with each charging/discharging cycle. In street terms, kind of like bending an aluminum can back n forth--eventually they give and reverse their polar electron field because they`re unstable. Why do you think Hybrids are going through Generations ? Theyre at the stage where lithium cells may come in but ask burned vapor cig owners and Samsung cell owners about that--hmm, a japenese Hindenburg--new image of a wienny roast !

are those under 100,000 mi original toyota warranty? thx

Wrong work to remove cells

Some body knows where can i buy a cell réplacement??? For my cambry 2008

need to load test for at least10 seconds
