The anticipated battery life for Notion Sensors is approximately one year.
Battery life is determined by the usage of the sensors and the hardware version. In an effort to preserve the electronics in the sensors, we made the batteries easily replaceable without any special tools.

When replacing your batteries, you will have the best performance with Energizer Ultimate Lithium AAA’s. You can use normal alkaline AAA batteries, but you may notice a shorter battery life as a result.
