You did it right. The module with only 6.4V has one of its internal cells permanently shorted. Unfortunately a shorted NiMH cell is a permanent...
Well, that doesn’t look good at all!
Please check all 28 modules in your recently acquired HV pack. Modules that currently have >7.0 volts are likely to be good and could be used as...
First, about me and my Prius: I did a partial restoration on my 2005 Prius HV pack 5 years ago. After barely driving the car at all during 2020...
I recently got a P0A80 code from my 2005 gen2 Prius with 110k miles on the odo. Like the original post in this thread, I rarely drove it during...
Thanks! That makes total sense to me. The hole in the car body would have been unthreaded and slightly undersized. When the special thread-cutting...
Can anyone offer an explanation for why Toyota used a different bolt for this one particular HV battery pack mounting hole? -Greg As an...
For many many years the US military extensively used NiCd cells in aircraft. One of the military standards called for putting a shorting wire...
I'll check the "off state" 12V current drain on my 2005 Prius and post the result. I've measured the 12V rail voltage numerous times but not the...
There's a pretty good chance that the root cause of this issue is with the wiring, or the fan controller module, or with the fan itself. There's...
I stand corrected. One early news report stated "kilotons" rather than tons. But all of the current news reports describe the explosions as 3...
One news report stated the first explosion was about 3 kilotons of TNT ( 3 kT), whilst the second (larger) explosion was about 20 kilotons of TNT....
I can assure you that the device shown in those pictures does NOTHING other than pure placebo effect. Such a small capacitor ( 4,700 uF) isn't...
Check for DTC code P3009. P3009 is the DTC code for a "ground fault" in the high-voltage circuit. The entire high-voltage section is completely...
If I was to purchase a salvaged HV pack I would want to see it INSIDE the donor car first. Having repaired my own HV pack i can testify to the...
Confirmed: That module was faulty. Self-discharge of a good module is very slow. I have several spare modules on my workbench that are still...
Random warning indicators leads me to suspect that one or more of the busbar connections on your HV battery pack might be loose or dirty enough to...
How did you identify the DOA module that came from ebay?
Green tec says their premium grade HV battery for 2004-2009 Prius contains "NEW GENERATION CELLS." But are these modules actually NEW? I wish...
There's one more important test that you should do: "Self discharge." This is done after charging. Disconnect the charger. Then let the...
