Probably be next weekend before I do anything else. I will go back and look at the spreadsheets on that other thread, did you actually load an excel file attachment that I can download and use? My Excel skills are pretty weak on building spreadsheets but I can modify and add data in "most of the time" without messing the entire sheet up too badly LOL.
I have the Turnigy balance charger/power supply and leads ordered.
I will update next weekend if I can get all the stuff together and get started. Not sure how long the Best Hybrid company will let me to keep the core before they need it back. Hopefully a few weeks so I can get this done. I have a guy interested in the old battery and I explained to him that I would be testing it and I will let him know the battery health so he knows exactly what he is buying. It may turn out to be total junk like yours and I will just drop it in the wooden box and say good riddance. Just so weird that the truck drove so well with it in there. Real live data coming soon. Like a treasure hunt I love it....

Thanks dnt1010 - you got some great pics and an awesome write up there. Appreciate it.

I'm also providing an update from the original thread - I decided to install the aftermarket head unit as I decided that was bothering me more than an average-running hybrid battery. It FIXED my issues with the screen dropping out, which I guess would only mean it was a bad stock head unit. Really weird problem to have, especially with the symptoms I was having, but it was NOT an electrical issue.

The kit that I ordered from Crutchfield included EVERYTHING I needed in order to install the head unit into my car. I was able to keep my factory rear seat DVD player, steering wheel controls, the factory backup camera, and all of the corresponding parking sensor/door/turning signal chimes. It has Bluetooth, full OEM stereo integration, Apple Carplay, Android's version of Carplay, all of it works perfectly. I paid Crutchfield $25 for their ReadyHarness service- if you are ordering a new head unit and don't have anything less than advanced experienced in wire splicing, PLEASE DO THIS. You give them your exact make/model/year, and they splice all of the wires that you need to install the head unit in your car, and put all of the unnecessary wires in a separate bag that you can throw out. Worth every penny. We got everything working except one feature on our first try - the last nonworking feature was solved because I hadn't pushed a connector in far enough so it didn't snap on. Done. Bit of a PITA getting the wires stuffed into the back of the console, but it looks pretty. Pictures below, one of the head unit in my car (dont mind the ghostlike reflection of my father's face in the screen), and one of the total equipment list to get it working with my car.
