I'm still on the original pack and there is no evidence of deterioration since I began monitoring it. I suspect what I've learned about battery maintenance has led to me be being more gentle than ordinary drivers ... it may last a very, very long time.

The only operational mods from a stock Prius:
  • Type WS transaxle oil - the same as the NHW20, it reduces drag
  • Sumitomo T4s - running 50 psi, they are rated low rolling resistance
  • Water noodle lower grill block - in the Fall, Winter, Spring.
  • Commuting car only - we have a ZVW30 for cross country and errands
I also have a 1 KW inverter for emergency power but that has no impact on operation.
