How long should the battery last?

The battery has a life-time of at least 1000 measurements.

When the user installs new batteries and gets readings thought to be inaccurate, please check the following:

How old is the battery? Batteries loose capacity over time even if not used.

Please ensure the battery is new.

A battery may work with other devices (alarm clock for example) that have a lower minimum required input voltage but may not work with the thermometer.

If the Microlife product remained in the warehouse of a Microlife dealer for a substantial time, the lifetime of the battery can be significantly reduced.

Room temperature also affects battery life. At temperatures below 15°C, the performance of batteries is reduced significantly!
