Endured ~ -25C to 25 C (always mounted in the car) so far. I was also concerned for the battery because people rated it to work from -10 C to 20 C. I always recommend to my family and girlfriend but they always say "Why need a dash cam unless you're an unsafe driver." Their loss I guess.
It is the heat that is the bigger concern when it comes to bulging.
I can almost guarantee most people who say they "have no issue" have not opened their dashcam to look at the state of the battery. I had one where I opened it up just after 4 hours on a hot day. There was no physical outside appearance of an issue but once I opened it, the battery bulged and was showing signs of punctures starting (the battery pushes against internal components and can get punctured).
Basically, you have no clue until you open it up.
If you speak to any expect about dashcams, they will all tell you the same thing. Capacitor only. It is not worth the risk of a battery.
