1. How long will my battery last?

Sensors use a common CR2032 lithium coin type cell.

The battery will last for approximately 4 to 8 months under typical conditions, but there are certain conditions that will affect battery life. When Impact Detection is enabled, the battery life will decrease depending on the frequency of movement and impacts. Lithium batteries, like most batteries, are sensitive to cold temperatures and their battery life decreases when exposed for extended periods of time.
