I'm coming down on the side of batteries don't make sense in the mountains, where it is steep and cold. (In the suburbs or city IMO they are a no-brainer.)
Driving to Belle on Sunday the CRV barely eeked out 30 on the way up, I got 42 on the return. The difference is the elevation gain/loss. Hauling batteries up the mountain, it's just an ICE with one hand tied behind it's back. If you average the 42 and 30, I got 36, and I'll bet my old CRV would have gotten 32-34 on the same trip, driving a lot faster.
Also, it's colder now and it's getting hard to hit 40 mpg on the way to work. I was 42-45 over the summer. Every morning now when I start er up, the ICE runs right away. In summer I was driving half a mile on EV to start. It's got to be the cold.
The plan was always to sell the CRV after we move. Just that now I think it is going to be traded in for ICE pickup, probably not a hybrid.
