What a great help! Found one more needing replaced. Imagine putting it all back together and finding that out the hard way! Thank you!!

Excellent! I actually gave up after trying to test cells and replaced a battery. I won't do that again!

won't the resistance feature on a battery charger measure this just as precisely? I'm guessing if anyone has yanked their battery, they are preparing to charge it with such a charger. My sky RC charger for example can measure resistance. Or is that inferior in some way?

I saw a video, way back, where they used a regular load tester on a newly assembled battery and went right along checking each module, disregarding polarity. The tester was one of the ones that's box shape w/ all the holes in the front and a meter above that. There was a switch at the bottom and it had short cables with large alligator clamps. HFT $20, I think the type was. 100 amp carbon pile. I'm sure there is no reading of internal resistance but it shows the draw=down over a few seconds. I wanted to know your opinion on all that. Specifically, does internal resistance correlate to voltage draw down?

thank you for this great video. What does this device do differently than simply using a multimeter to test resistance?
@cvedeler2 ай бұрын
It puts a load on the battery and tests internal resistance. My simple multimeter can only test resistance, but can't even do that with voltage present. .

@@cvedeler Ahh, I see. Since anyone considering this procedure probably already owns a charging unit, I am wondering if the resistance feature on such battery chargers would work just as well, or are they inferior in some way? I have the SKYRC B6AC for example.

When you replaced the bad module, did you have high voltage difference compared to the other modules? I replaced a module and showing 1.2 voltage difference and throws the "check hybrid system" p0a80 code on my odb2 reader. I need help.
@cvedelerАй бұрын
The voltage of the cells wasn't my problem. All my cells were +/- less than 1 volt. It was the internal resistance that caused my problem.

I just replaced 3:54 all the blocks of my Lexus CT200h (same as prius.) After all done, the P3021 came up; it indicates that block 11 becomes weak. Any ideas? Do you think one of the blocks came bad? I refurbished all the blocks my self at once with new cylindrical ones. 😢

I used the onwei tester and it come out as all the modules are bad. It also give you an option to choose the kind of battery, like agm, lithium and 4 others. Resistance was around 5.4 and 6 all across. I don't think this really work good for hybrid battery module.
@adrianleighuk4 ай бұрын
A question. Once reassembled did this help resolve the issue and if so in your experience what was the best internal resistance as a guide? Thanks for the video. A great idea by the way.

It worked well. I had one terrible cell, but ended up replacing 5 others that were questionable.

Chris, your test method was indeed creative. But are there devices more suitable for this kind of testing? The battery tester you used was originally designed to test the 12v starter battery, not for a 7.2v (nominal) module. Other than worrying about the reading would be inaccurate, I do not know how that "500A cold cranking amp" was tested, and I wouldn't attempt (until I watched your video) to use it, for fearing that it would draw too much amps from the battery module thus potentially damaging it.
@cvedeler2 ай бұрын
I'm sure there are many deices more suitable, but they are likely more expensive and harder to find. This is cheap, easily available and works well enough to find the bad cells. I was a little worried about the fact the device is for 12 volt batteries and not 8 volts. But it turned out working anyway. Lower voltage is probably less a concern to higher voltage. Accuracy isn't the goal, but rather finding the cells that may show adequate voltage but fail under load. Such a small device can't possibly draw 500 amps so I wasn't too worried about that.

i used the tester you used. results voltage abovr 7.55 all cells resistance 5.00 milli ohms, all 100 healthy. but says all cell have zero charge left. what is the solution.how to charge ?
@cvedeler3 ай бұрын
7.55 volts is too low. They should be closer to 8 volts. My lowest voltage cell was 7.71. If the cell resistance is 5.0 but the voltage is low, that points to a different issue, possibly with the charging system. Good luck!

Unfortunately doesn't work that way. I used this Viking battery meter on my Prius 3rd generation cells and it showed 100% state of health, 7.95V on everyone and very low internal resistance. Even though my battery had a problem on block 13. I had to run a Dr. Prius app test to see it and disassemble the battery again to replace it.
