Low temperatures mean less chemical activity, so battery life is longer.
That's also why it's harder to start a car in very low temperatures - the energy is lower, plus the thicker oil in a car that's been sitting overnight
10F-30F is -1C - 12C.
My shooting experience with digital camera is between - 28 C and +35 C.
Not sure what cars analogies have to do with photography forums, but if digital camera will be kept outside overnight at -12C, it is going to be dead in the morning. No cold start at all.
To more practical to photography experience, pocketable or else digital cameras will lasts longer in freezing weather if they are kept closer to the body heat, but not too close.
Again, from my practical photography experience, batteries lasts longer (while in use) in mild weather between +10 and +20 C.
For cars under very low temperatures you need to use appropriate oil and battery which holds the charge.
But "very low" temperature is totally variable term these days, with most forums participants been south from Canada border and England, Central Europe

I have started driving in Lada, at the country of origin. No Varta and no Pennzoil. To start in -25C overnight, we would pour glass of gasoline into the oil reservoir, while engine is still warm after parking for overnight.
