I know this has probably been covered a lot, but what was the original battery capacity in miles (very subjective I understand) for a 2013 energi? I bought mine 4 years ago with 60000 miles on it and now have 117000. About 43000 are EV miles and around 4200 are regenerative. Seemed like when I first got the car it got around 21-22 miles on a charge in summer and maybe 15-16 in winter. This past year it has been 10 or so in winter and around 15 in warm weather.
So the other day I decided to charge it up and as soon as I pulled out I switched to EV later. I drove around town and used the regenerative braking to hopefully break through any old barriers there might have been in the battery pack. I did this for 3 straight days (I retired, I can do this). Anyway, after th first day I noticed a jump to around 16, then the next day to 17, and now after another day or 2 I got a reading of 19 when I started to drive. So i took a long drive and drained the battery and it just finished charging. I will be curious if it is back up around 18-19. Hoping so.
