Good question - the CirrusSense Bluetooth Wireless Filter Pressure Gauge replaceable battery lasts up to 2 years. When you open up the package it is ready to work once you attach it to your filter and connect to its app! You can see an image of the battery in the image gallery on the product page. You can contact the manufacturer or us in the future for replacement batteries, which are not expensive.
