Graph of battery discharge: a red line declines steeply at day 400, whereas a green line remains steady, close to where it's been since day 10.

   New battery test, day 400: 3.07 volts. This is very exciting! It wasn't that long ago that the original battery test (red line) was limping over the 400 day mark at just 2.4 volts, the energy of beeping the buzzer causing it to drop 100 mV. With the new firmware, we're still sitting strong at nominal voltage, and even the heavy lift of lighting the green LED causes a drop of just 10 mV. 💪
