Built with the IoT in mind.
They say it draws 20mA. What voltage is that at? Being generous and assuming it can run on 1.5V, you would get 60 hours out of a 1200mAh AAA battery.
Let's run it the other way... assuming 8 leap years in the 35 year period that's 304416 hours (check me I'm tired) so 1.97e-4 volts?
That doesn't make any sense. The voltage will be 1.5V at lowest. No semiconductors operate at the microvolt level you suggest. If anything, you'd be pumping the voltage *up*.
I assume the battery life is based on 20mA during short infrequent duty cycles, with a much lower (by orders of magnitude) dormant current draw.
Yeah, you'd get a perhaps hourly update. 35 years still sounds ridiculously optimistic. I'd guess a year at best.
