I have a Jetson Nano configured with a diode and ML1220 rechargeable battery. However, I have noticed on a couple separate occasions that the RTC will fall out of sync if the device is not powered on for 2-3 weeks. Is this normal?
I understand the battery is supposed to provide 2.5-3.5V, and other posts say it can run with as little as 1.65V. I can start measuring the voltage of the battery cell over time, but that means I’ll have to not power on the unit for a few weeks.
