The battery has lasted this long, but I will change it soon just in case. The bell is not used a lot as it is in a secure apartment building and we have few visitors. We do get a lot of packages, though, and the bell is often rung when a delivery has arrived. The system has never failed. Highly recommend this doorbell system.
