Hi jsamp - I'll check out Greentec.
I'm looking ahead a bit because I like this car and I'd like to support the battery refurbishment industry if it comes to that.
I'd say the battery is passable. I can get 8-12 miles EV with careful driving and minimum accessories. However, it has blinked a couple of times - once the car stopped using the battery completely and another time it lost charge too quickly.
To preserve the battery I'm treating it like my phone -
generally keeping the total battery charge around 50% SOC (total capacity, which I think is now around 25% on the EV percentage gauge),
not charging above or below 30%/70% (0% to 60% on the EV gauge)
not using fast chargers often
and running the engine with "EV later" when using air conditioning and heat.
