New battery test, day 450: 3.05 volts. Actually I'm calling it 3.045, because it was 3.04 when I arrived at the voltage measurement screen, and then it bounced right back. These latest numbers signal to me that we are, in fact, making the turn: the green line is beginning to curve ever *ever* so slightly downward, akin to what the old test — red line, with the less efficient firmware — did at day 200. Does this mean we're at the halfway point of this new test? Time will tell!
