Ran low temperature test with the display at the dimmest setting in 18ºF temperature compared to one running at 70ºF. Previous attempt was using Duracell batteries in which the freezing temperaturebrought the batteries down to 0 Volts only after a couple of hours. This time around I had Energizer batteries and they are performing much better.
After 12 hours we've drifted just under half a frame compared with the one running at 70ºF. The batteries lasted about 18 hours before display became too dim to be useful.
