The batteries inside of your sensors should last close to a year. When it comes time to replace them, you can do so by following these steps.
- Grip the outer housing of your Notion sensor.
- Turn counter-clockwise (like you're twisting off a bottle cap.)
- Carefully lift the battery out of the battery holder. You can either grip it with two fingers and lift it out or use a small screwdriver and lever it out using the gap on one side of the battery holder.
- The battery can be replaced with a CR2477N coin cell. Press it into place with the smaller diameter side facing down.
- Once the battery is firmly in place, twist the sensor cover over the top of it. It should twist on in a clockwise rotation (like your resealing a bottle cap onto a bottle).
CAUTION: RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO LOCAL DISPOSAL REGULATIONS FOR LITHIUM BATTERIES
