It’s probably only a cell failure not the whole battery. Google prius battery repair in your state would be my suggestion. I drove a mk2 to 147k no issues
According to the print on the modules, mine were manufactured in Dec 2021. The gen 4 modules have a slightly different plastic casing compared with Gen 2 modules - look at the vent hole and plastic tab design. Gen 2 vent holes have a relief valve, while gen 4 holes are actually closed! I'm assuming (hoping) chemistry has also improved over the years.
It doesn't come as may surprise to me that they use the same modules across all batteries. I pretty much expected that that was the case. Thanks for taking the time to post the photos—as they say, a picture is worth a thousand words.
I got a reply from Olathe Toyota telling be a Gen 2 hybrid battery was available and around $1950. What the heck does that mean ? Around. Like heyIll offer $1,600 and you will sell it to me? Very strange. I’ll follow up.
Indicative pricing for the tire kickers. If you really want to place an order, they will give you a firm price. That's my take.
