Prius Alpha or Prius Plus or Prius v 7 seater has Li-ion Battery. This car has been on the road since 2012. Already 11 years gone but still this battery going strong. In hot country like Bangladesh, the Alpha made in 2013 are running with stock Li-ion Battery. In cold countries like Europe, this car even run better and even some have already driven 500k km with original battery. So my guess this first generation Li-ion battery will last 15 years or more. What do you think?
