Do a Google for replacement Fusion Hybrid packs. I found none. I did find 05-09 Escape refurbished packs though. Simple reason you dont get many hits(aside from keyword search) is that there isn't a big market yet for refurbished Hybrid batteries. As stated before, you can probably find used batteries from wrecks that are like new, for much less than any company can refurbish them for. No profit margin in it yet.
There are however some companies cropping up that will service your existing pack(NickelMetalHydride only) for a small fee. They take the pack out, test each cell and perform a reconditioning cycle on each cell to bring it back to near new condition. The 2010-12 FFH does this as needed, but sometimes a cell could become stubborn and not take the reconditioning cycle properly. They may also be able to replace a bad cell for far less than a replacement pack will cost.
It will soon become no different than automatic transmission and engine rebuilders. A few companies will get the golden share of the business and make out well, while others might branch out as a side line to it, but not make anything off of it to be a contender. With the surge of newer and more choices of Hybrids, now is the time to get into battery refurbishing, but the startup costs wont be recovered for quite sometime until the market is out there, will take a few more years as the miles pile on, but eventually there will be enough Hybrids out there that will need packs refurbished or reconditioned. Especailly on those who drive their cars to 500K or more.
