Battery Life Calculator for SL50 series button data loggers

The SL50 series of data loggers are sealed for life with an internal battery that cannot be replaced.
The loggers therefore have a life, at the end of which it must be replaced,that life depends upon a number of factors such as the sample time, the resolution and the ambient temperature they are exposed to.

This tool enables the minimum product life to be calculated.
For short cycle high temperature applications it is often better to consider this as the number of cycles that can be logged.

To optimise battery life follow the rules below:

  • Use the maximum log interval that you can accept.
  • Using low resolution will significantly increase battery life.
  • Use, wherever possible, the 'Stop When Full' mode so the logger does not carry on logging after the test.
  • When the logger is not in use for significant amount of time, battery life an be increased by changing the logging interval to 24 Hours.
