The InTemp data logger requires two user-replaceable AAA 1.5 V alkaline or optional lithium batteries for operation at the extreme ends of the logger operating range. Expected battery life varies based on the ambient temperature where the logger is deployed, the frequency of connecting to the AccuShelf, and battery performance.


Note: Make sure the batteries installed have flat negative terminals. There should be no indent in the bottom of the batteries. Batteries with indents in the negative terminals may become loose and prevent proper operation.

To install or replace the batteries:

  1. If the battery door is already installed on the back of the logger, use a Phillips-head screwdriver to remove it.
  2. Remove any old batteries.
  3. Insert two new batteries observing polarity.
  4. Screw the battery door into place.


Once you replace the batteries, please call or email TruMed Support immediately to re-launch the logger:
