Home / Battery Replacement Guide

Find below a short video demonstration changing Tempdrop's battery.

Tempdrop takes a CR2032 3V lithium coin cell battery. It can be purchased on Amazon or at any store with coin cell type (watch) batteries for a few dollars. Every Tempdrop ships with a wand to help replace the battery and each new Tempdrop sensor has arrows to indicate the opening points. 

Alternatively, you can find one such tool on Amazon by searching for an "opening tool kit." See below.

For more detailed, step-by-step instructions, scroll down.

Please note that once the sensor is opened, any stored data will be erased so be sure to sync before replacing your battery. Changing the battery mid-cycle will not affect your temp results.

To replace the battery on Tempdrop, you'll want to use fingernails or a plastic tool, not a metal tool like a screwdriver.

 1.Gently use the tool to separate the front and back sides of the Tempdrop sensor according to the indication arrows.

 2. Remove and swap over the battery. Ensure your battery is removed and inserted the correct way. Note how your battery is placed before removing. 

3. Before you reassemble the Tempdrop sensor, make sure that the inner frame arm is clicked down into the bottom shell as indicated below.

4. In order to close the sensor, hold the wider, bottom part as shown and use your other hand to click the two shells together around the edge. Don't press in the middle of the sensor. You should hear a click.


If you see a gap between the 2 halves, reopen and check the inner frame as outlined in step 3 or reach out to support for more help.
