Never bought a rebuilt before, only rebuild them myself. My last failed HV battery needed some cleaning, one module replaced, minimal balancing, and is now approaching two (2) years and 16k+ trouble free miles on the road. Your mileage may vary.

Before investing is a replacement, pull apart what you currently have for a quick look see and take some voltage measurements. The longer you leave it unused the easier it will be to see the voltage droop, or you can fire up techstream and test drive it instead.
