Yeah, I worry about our HCH's battery when we drive in the mountains. My SOC looks like a yo-yo and I know that it must be hard on the battery. I always thought it would be bad from the perspective of running the battery down low, but never about the temperature aspect.
So what are these data monitering devices you mention?
Commuter car, grocery getter, and summer road tripper--average 10k miles per year.
Winter road trips and ski trips, bad weather commuter and my wife's "daily" driver--expected average 4k miles per year.
