I found the below article on Reuters and pulled out some of the highlights. It sure looks like these will be re bundled cells with about 80% of new capacity. In my situation, it took me 3 years to get to 51Ahr (80%) and almost another 4 years to get to where I am now. So I can pay $2800 for 4 years ($700/yr) or $5000 for 7 years ($714/yr). At about the same cost, having the extra range for a few years is appealing.https://www.reuters.com/article/us-nissan-battery/nissan-spins-up-new-plant-to-give-second-life-to-ev-batteries-idUSKBN1H30DD
The batteries will be produced at the new factory in Namie by reassembling high-performing modules removed from batteries whose overall energy capacity has fallen below 80 percent.
Modules with capacities above 80 percent are assigned for use in replacement Leaf batteries; lesser modules are reassembled and sold as batteries for fork lifts, golf carts, and lower-energy applications such as streetlamps.
Makino said it would be difficult for 4R to completely break down and recycle EV batteries on its own
The plant can process 2,250 battery packs a year, and initially plans to refabricate “a few hundred” units annually, Makino said
