It should theoretically have a very long operational life. The switch came with the battery separate, but opening it the first time was extremely difficult. I thought it was going to break. I could see some of these being damaged just trying to put the battery in for the first time. Other listings show a battery pull tab. I've ordered a version with external battery drawer for us to take apart.
