How do you change a battery in a digital thermometer?

The digital thermometer battery replacement is not difficult and can be completed with a few simple tools. Here are the steps you can take to change the battery in your digital thermometer:

  • Open the back of the thermometer case and remove its battery compartment cover by exerting a small force in pulling it off.

Why it’s important that the battery is fresh and not old or dead?

It’s essential that your battery is fresh to ensure its optimal performance. Having an old or dead battery could impact the accuracy of data or measurements of your digital thermometer or causes a delay in taking temperature readings.

How to tell if your digital thermometer battery needs replacing?

You can tell if your digital thermometer battery needs to be replaced if you notice that its LCD is dim or blank, and it takes a long time to get an accurate reading, or sometimes it won’t read at all. Typically, your thermometer’s battery needs to be replaced if it’s more than five years as it has already worn out.

How to store your batteries properly for maximum life span and safety?

The digital thermometer battery life is not indefinite. Depending on the brand, model, and settings, a digital thermometer battery may last anywhere from 3 to 5 years.

Here are the essential things you should know about storing your thermometer safely to enhance its lifespan:

  • Before and after use, wash the thermometer in warm water.
  • Sterilize it by using a cotton ball coated in alcohol.
  • Do not clean it with hot water or bleach.
  • Store it in a cool and dry place.
  • Keep it away from the reach of children.
  • Place the probe cap or plastic case to keep it away from dust particles.

Final Thoughts

Changing the digital thermometer’s battery is easy and can only be done within five minutes. Be careful when removing the old battery as this might damage its compartment, prompting you to buy a new thermometer since it’s sensitive. Also, clean off the dust from its sensor lens before replacing it to get accurate readings and prevent condensation buildup. Lastly, dispose the old batteries properly as they might be swallowed by a child, causing death or injury.
