Adafruit DS3231 battery life

Post by pedro98 »

Hi,

With the Adafruit DS3231 Precision RTC Breakout (https://www.adafruit.com/product/3013), how long is this expected to work if it is only powered by the coin battery?

Thanks

Our product page states years of battery life.
With a coin cell plugged into the back, you can get years of precision timekeeping, even when main power is lost.

The datasheet has some details about the current consumption.
