BATTERY TEST, DAY 425: THE END. I measured 1.8 volts two days ago, which officially marks the end of the graph’s Y-axis. Today I woke it up for this test and watched it sag from 1.7 to 1.4 volts as I changed modes, the LCD dimming slightly in between each button press. Then I caught the exact moment this test ended: 11:46 AM central time, or 10,198 hours continuously running the old firmware. 🫡
