In my case, "any issues" basically means doing an excruciating amount of additional work or putting the battery's health at risk. Once I do check these modules if possible, how old is too old? What if these modules were refurbished, is there such a thing as too old or is module health more or less a game of chance over time? Please forgive any ignorance I'm new to the Prius world and am learning.
You're working on your battery because there's already damage done to the modules from age and use degradation happens to battery over time and usage That's why you playing with it You're trying to salvage something out of it for a few more weeks months something The end-all be all is going to be you get out of the car or get a new battery or you can get refurbished but that's just a stopgap measure while you save up money to buy a Tesla or something I don't know but the batteries already degraded That's why we're here having this discussion.
