I finally got around to doing the "Tony Test" GOM reset. I got 138 miles. I have had the car for 42 months and 37,000 miles. The car was manufactured in 11/2012 according to the information plate at the bottom right of the driver's door opening.

138/146=94.5%

I just did an Extended charge about 7 hours after a Standard charge. It added 6 kWh in 47 minutes. That was more than I expected. Of course, that is energy from the wall, but it's still a lot of battery energy in the Extended portion.

I have nearly 45,000 miles on the car now.

That's a pretty solid battery.

Finally found the time to get this test done, did extended charge from 70% or so SOC to full on the 120v trickle charger, unplugged the battery for about an hour (all the time I had) and upon reconnecting saw 139mi on the GOM. 139/146 = just over 95%. Car has 34.5k miles on it and outside temp was approx. 75°.

Seems to fall in line with miimura's results above. One question, when I turned A/C to Eco Hi, the GOM dropped to 107. Is that just because we've reset the computer, or does the A/C really kill that much range?

The deduction for the A/C is also reset. No, Eco-Hi should not actually take that much.
Deduction should adjust back to what it was before the test in a week or two.

I have stopped using eco A/C in the Summer as it has been said the standard mode provides better battery cooling.

Finally did Tony test on replacement pack done at 71k miles. Have almost 9k miles since and am running at 141/146 or 3.5% degradation. Happy I didn't get a refurbished pack with more than 10% lost.


How did you get a replacement battery pack?

Warranty replacement. Low voltage on string, would shut down car. Had to tow it to dealer 3 times. Took to dealer 5 times over two weeks they cleared errors and would send me on my way but next day when trying to start it wouldn't start with EV system error.
