±1 minute per month at 25°C

±1 minute per month at 77°F

1 year, typical with logging interval of 1 minute. Faster logging and/or statistics sampling intervals, entering burst logging mode, and remaining connected with the app will impact battery life. Excessive readouts, audible alarms, and paging all impact battery life. Visual alarms and other events can have a marginal impact on battery life.

Two AAA 1.5 V alkaline batteries, user replaceable
