The short answer; depends on what sensor, network, mounting place, and network conditions you have.
Z-Wave
Under “normal use,” following our recommendations, the battery life is expected to be 10 years. See this test and verification report.
LoRaWAN
Like Z-Wave Strips, they are optimized for low power consumption that, under the right circumstances, last 10 years, or more. However, this is highly dependent on the profile settings. Please verify your expected battery life with our battery calculator.
