What ?? I think the real answer is: NO they don't and won't........with a few possible obscure exceptions.
Why not call a few in the area, and ask the service department directly: Toyota Dealerships | Certified Toyota Dealers in Port Saint Lucie, FL
There are no procedures in the Repair Manual (more info), or as far as I know, in other Toyota publications, for HV battery reconditioning, only for removal, disassembly, reassembly, and installation. There is a procedure for charging the HV battery with an external charger, but this is used only if the HV battery is so discharged that the engine cannot start. For North America, the details are in Toyota bulletin T-SB-0119-15, “High Voltage (HV) Battery Rescue Charge (HEV Workstation / GRX-5100).” As Toyota writes in 2016 Toyota New Technology Update: Course TIN516A Handbook, “A rescue charge does not ’refurbish’ the HV Battery or repair faulty cells within the HV battery pack.” @SFO's kind suggestion to ask the dealer is a good one, however. Dealers are independent businesses, and I don’t know why they wouldn’t be allowed to offer their own HV battery reconditioning service, if they choose, just as they can offer other services not recommended by the manufacturer.
Toyota addressed the known problem of nickel-based batteries needing to be reconditioned by allowing the battery pack to continue to operate the car when the pack is so in need of reconditioning it's only at 50% of original capacity. Reconditioning or "cycling" the battery pack several times can restore the pack to 96% of original capacity. Toyota had to decide between investing in a battery maintenance service, or even building a system into the vehicle, vs. investing in a battery pack that would last just long enough for the owner to spend thousands replacing the battery pack or the car. While profitable, their decision is also wasteful and irresponsible in a world with finite natural resources. So companies like hybrid automotive and other built aftermarket systems for battery reconditioning. Learn more here: FAQ
The OP joined Prius Chat in 2008. That's 11 years ago. I joined in 2009. Now speaking only for myself. I have never read a single thread that talked about a Prius Owner taking their Prius to a Toyota Dealership for Hybrid Battery reconditioning. So why the question? I think it's answered by empirical default over the course of a decade.
True on all points... Yet you've clearly underestimated the ridiculous nature of social media-based DIY forums...
Things change I suppose. The Toyota dealership in Murfreesboro TN offers a reman with 6 month warranty for $1700 incl tax. Out the door of parts dept. (Not including install).
I don't see that as a very good deal. You can get a brand new Toyota factory battery for 1655.36 + tax. currently. Should last at least 10 years. Battery - 2004-2009 Toyota Prius (G9510-47031) | Tracy Toyota Parts
Do they define "reman?" If it has all new cells and they cleaned or replaced all the connectors and harnesses that needed it, that would be about what would happen if you bought a new battery. If it's mix & match and not replacing all the cells, then that would be like the refurbs that only last a few months.
