An excellent thread on Prius batteries is on http://forums.whirlpool.net.au/archive/2071810 Our 2002 Prius (ex-EPA Vic) is one of a reported 610 Series 1 cars imported to OZ by Toyota, and there were private imports. Although numbers are low, parts should be available - no need to scrap cars built to go 1 million km. The 2002 is still going on its original HV batteries, after 14 years. Our 2006 (ex Adelaide City) model`s batteries played up just before the 8 year warranty expired, and Toyota replaced them, free. The dealer said the cost was $3043.
