I only have 400 miles on my Karma and it looks like the low 40s is where I am at the moment. I did use a half-gallon of gas so far. My bad.
Before I bought my car, I drove a higher-mileage demo for a 150 miles and got almost 50 miles out of the battery. But it was a borrowed car and I drove it very cautiously and with a light foot. (You break it - you own it.)
I'm just wondering if, at the beginning of a battery's life-cycle, storage capacity increases over time as the battery becomes "conditioned." Anyone? (I know what happens at the end of the life-cycle.)
