Got the red triangle of death today but it went away on its own. my tech stream was messed up and wasn’t communicating. Anyway, the stereo was cutting out intermittently and I'd had the car on sitting idle for a bit so I figured it was likely the traction battery. I'm still planning to check with Dr. Prius to see about battery cell issues. When driving at highway speed, it will light up all but 1 of the battery cell marks on the energy display. Meanwhile, I went to the junkyard and found a Gen 3 although I don't know the mileage on the battery. I did see some corrosion on maybe 9 or so small terminal nuts. This car is recently in the inventory (maybe a month or so) and has very minor collision damage so I'm thinking it may have been sitting for awhile. I removed the safety plug and the battery cover to measure voltage. I didn't remove the terminal nuts but did try to measure voltage between positive and negative terminals on several individual batteries. These all measured near zero. Does that mean it's been sitting forever or would I need to remove the small terminal nuts to measure voltage? Is the battery likely hopeless or could it be reconditioned?
Do a lot more research - gen 3 modules are slightly different from 2 I believe. I posted a wiki of my experience. I repaired my hv battery in Dec. Prius High Voltage Battery Reconditioning | PriusChat
Maybe they are is some small way, but Gen 3 modules can be placed quite satisfactorily into a Gen 2 case.
They work great in a g2. yes all those modules are likely dead from sitting. They probably can be resurrected but it all depends how much for the battery and are you ready to become a full blown battery reconditioner which includes all the equipment, Tools, good electronics background, place to do it and the time. And be a gambler because some of the cells may be sketchy. my formula for projects like this has proved flawless: takes more $ Than I thought. more difficult Than I thought more physical than I thought and a lot longer than I thought lol..... and good luck.
