Have drivers experienced a decline is performance/efficiency that's noticeable to the driver? (that is, without a multi-meter and bench experiments!)
In general, there have been very few problems with the Traction batteries in Prii (some connector corrosion events in the 2001-2003 models). My 2004 is at 106,000 miles and no problems. Prius batteries are made by Panasonic. Yours are not, so YMMV.
