Regularly replacing the battery in your smoke detector ensures it remains functional and keeps your home safe.
To change the battery, use a step stool or ladder to reach the smoke detector. Open the battery hatch, remove the old battery, and take note of the positive and negative terminal placement. Insert a new 9-volt battery in the same orientation, close the hatch, and press the test button until the alarm sounds to confirm proper operation.
For best performance, check your smoke detectors regularly and replace the battery as needed. Refer to your Homeowner Guide for additional details.
