Battery Life

The sensor uses a lithium non-rechargeable battery, capable of an estimated 200,000+ messages.
Note: Refer to the Sensor Battery Estimator.xlsx spreadsheet on the on the sensor's product page for specific
battery life estimates:

Battery life depends on the number of transmissions per day. Power required for a message transmission is greater
than the "sleep current" for high power radio technologies (e.g, LoRaWAN).
Different battery chemical types deplete over time with different voltage profiles; a lithium battery maintains high
voltage for the life of the battery with a rapid drop near the end of life, and an alkaline battery has gradual
reduction in voltage over time. Sensors ship with a lithium battery, which is the recommended replacement type.
Recommended battery: Panasonic CR123A
Battery life estimates in the online spreadsheet assume room temperature, meaning temperatures near the
maximum and minimum ratings negatively impact battery life. Battery voltage lowers in cold temperatures, and
internal circuitry needs a minimum voltage to operate properly.
Note: Battery life will be reduced in cold environments leading to possible device shut down.
The battery voltage and a low battery indicator are reported by supervisory messages. Refer to the section on
Message Protocol for details.
