How to Replace Smoke Alarm Batteries

One of the most important devices protecting your home is the smoke detector. We rely on these devices to warn of us danger, yet we often don't give them much second thought. If your smoke detector runs on batteries, it's vital that they be changed on a regular basis so the detector will work its best. This simple household task should never be neglected. Here's how you should replace the batteries.

Things You'll Need

• Step stool
• 9-volt battery

Instructions

1. Gently pry the cover off the smoke detector. Use your step stool to reach the device if necessary.

2. Dust the inside of the cover to be sure that the vents are clear. Locate the battery. It should be clearly visible, and will be the same shape as the 9-volt battery you'll be replacing it with.

3. Remove the old battery by pulling it out of its clip. Discard the old battery, or recycle it if you have the opportunity.

4. Plug in the new battery. Insert it firmly into the battery clip, making sure that the positive terminal is lined up with the positive tab of the battery.

5. Replace the cover. Push firmly to ensure it is on securely. Then test the smoke detector by pressing in the test button in the center of the cover.
