What is the amp hour rating for the monitor one?

I'm wondering if the device turned on, read 1 or 2 analog sensors, synced with a device to cloud ledger then Hibernated and did this 2x per day how long would the battery last in a monitor one?

The [Monitor One Battery](https://docs.particle.io/reference/datasheets/tracker/monitor-one-datasheet/#battery-specifications) is 12200 mAh. You can get an approximation of the usage by using the [Battery Calculator](https://docs.particle.io/tools/developer-tools/battery-calculator/). The Tracker One setting will be similar, but change the battery size from 2000 to 12200.
