As my lovely Gen 2 is now 12 years old (only got 77k miles on it), I decided to run the 'Life Expectancy Test', included in my (IOS) 'Dr.Prius' app, on the HV battery. I was really pleased with the result - 81.08% capacity, indicating the battery is still in very good condition. Does anyone know if this test is a reliable indicator of battery condition?
