Battery life

Battery life of a logger varies depending on the actual measurements the logger records. On a 15 minutes measurement interval, the average battery life for the Logmore Guardian Logger is 4 years. However, data intensive use can shorten the battery life. You can estimate the battery life and configure a logger's measurement interval on Logmore Cloud, see Logger Configuration.
