New battery test, day 650: 2.86 volts. Number go down! But even when number go down, watch can still function just fine, down to 1.62 volts (which realistically we won’t get to until the battery has but minutes left). If I had to guess, I’d guess I have 30% of my CR2016’s capacity remaining, which means we should easily make it to the two year mark, and I should be able to wear it all semester and well into the summer. If I’m being bold? I think it‘ll tick from February 2022 to September 2024. 🤞🏽
