Your Sensor battery life is valid for a period of 12 months after the date of registration, regardless of how many cycles you have used it for.
You will receive a notification from the App to say that your Sensor will expire within 30 days, providing you have synced to the App within this time.
There is just a small fee to cover processing and shipping, you will not be required to purchase a new Starter Kit.
