## Product: Dual Laser Infrared Thermometer
**Brand:** ennoLogic

Hey! Changing the battery in your ennoLogic eT650D is pretty straightforward. Here’s how you can do it:

1. **Turn Off the Device**: Before anything else, make sure it's switched off so there’s no accidental activation.

2. **Find the Battery Compartment**: Check the back of the handle. You'll spot a little door or cover that's the battery compartment.

3. **Open the Compartment**: You might need to slide the cover or use a small screwdriver, depending on your model. Open it gently to get to the batteries.

4. **Remove the Old Batteries**: Take out the old batteries. You'll likely need a 9V battery for this model. Just have a look inside the compartment to confirm the battery type.

5. **Insert the New Battery**: Pop in the new battery, making sure the positive and negative match the markings inside. Check to see it's in securely.

6. **Close the Compartment**: Shut the compartment. If there’s a lock or screws, make sure they’re secured properly.

7. **Test the Thermometer**: Turn it on to see if it’s working with the new battery. If it doesn’t power up, maybe check the battery alignment.

Choosing a good-quality battery will keep your thermometer running smoothly. 

And when you’re done with the old battery, remember to dispose of it responsibly.

Oh, and just a heads up—while it’s great for checking surface temperatures on stuff like cooking or HVAC systems, it’s not the one to use for taking body temperatures. For that, you'd want a thermometer specifically meant for medical purposes. 

Hope that helps!
