Is the battery safe at high temperatures?Updated 8 months ago

YES!

The Predictive Thermometer uses an LTO (Lithium Titanate Oxide) battery, which is very stable. Much safer than the Lithium batteries you’re used to (Lithium Ion or Lithium Polymer). The LTO survives up to 105 °C (221 °F) and will just break if you get it much hotter. Since it’s tucked away inside the thermometer, the water content of the food keeps it safely below the boiling point (100 °C/212 °F).
