The Kinsa QuickCare wireless stick thermometer uses one CR 2032 battery. They're small, reliable (we recommend Energizer or Panasonic), cheap (~$1 each), and easy to find at pharmacies, grocery stores, and the online stores below:
To replace your QuickCare’s battery:
- With the edge of a coin, turn the back of your QuickCare counterclockwise until it pops off.
- Tip your QuickCare to the side and the old battery should fall out.
- Insert the new battery, ensuring the larger, more reflective side with text is facing up.
- Replace the backing, and again use the edge of a coin to turn clockwise and secure the back of your QuickCare.
