I propose these criteria for "rebuilt" HV battery success: No battery DTC codes occurred after battery replacement MPG increased to a "normal"...
+++ on your suggestions, rebarron55. Thanks! I recently purchased a Torque/OBD2-USB dongle and also a mini-VCI. I haven't used them yet, but I...
Thanks Britprius! So there's some hope for Eddy2014's project... There was one failed module in my 2005 HV battery. One cell in it is a...
So it's abundantly clear from redbarron55's posts that rebuilt HV batteries from Prius Rebuilders Falcon Hybrid Solutions are less than perfect....
How would experienced forum members answer Eddy's question? Some of the literature I've read on NiMH cells suggests that allowing a cell to...
I'd trade in my 2005 Prius for a new one too, except that my wife and I need to finish paying off our other car (2013 Nissan Juke) before we can...
I have a Master's degree in Electrical Engineering. But I've never taught it. I don't have enough patience to do that. -EB
I agree with Texas: If you can possibly find a way to afford it, get the NEW battery from Toyota. The $ 2,600 quote from your local repair shop...
I didn't put all the trim back in place yet. I fully understand that more modules might fail within the next few months. I've equipped myself...
I suppose I should have contacted Toyota, but I doubt they would extend my warranty since it's only 8 years in Illinois. CA and some other states...
After reading every HV battery thread on priuschat I decided to tear mine apart and replace individual modules myself. I have a 2005 Prius with...
That confirms what I was thinking: Bad modules may have a very rapid voltage rise when they are charged. The most likely cause of this is that...
I really like the idea of cutting the top off a bad module and that way being able to access each individual cell. I've skimmed through the...
Thanks for that info! So am I correct in stating the following? Both gen2 and gen3 Prius modules are part number NP2 The version can be (none)...
It seems to me that the key items to look for when testing modules are: A sudden voltage increase while charging a module (for example, from 7.0...
How does one determine whether a module is gen2 or gen3? Aren't they both the same part number? (Primearth NP2) -EB
That's interesting. The bad module I removed from my Prius appears to have ONE cell which is a dead short. The module seems to have normal mAh...
Kiwi's point is that it's all too easy to ignore the module voltage when testing with RC charger/discharger units. A failed Toyota module with...
I totally agree with Kiwi about the difficulty of getting a reliable answer to this question: "How does one determine how much life is left...
Does your gas (petrol) tank cap fit tightly? Evaporative emission system tries to draws a vacuum in tank shortly after you start the car. If gas...
