This will vary slightly depending on a number of factors. In our testing, we've seen performance better than 2 seconds per million seconds. For comparison, that's up to five times more accurate than your average digital watch. The tiny silver oxide battery (8mAh, included) keeps the RTC running when your device (Raspberry Pi or Arduino) is
