Replacing the battery in your First Alert smoke alarm is a simple task that can be completed in a few minutes. By following these simple steps, you can ensure that your alarm is always working properly and protecting your family from fire.

Before you begin, gather the following materials: a new 9-volt battery, a Phillips head screwdriver, and a step ladder or stool (if needed). Once you have your materials, follow these steps to change the battery in your First Alert smoke alarm:

1. Remove the old battery by unscrewing the battery compartment cover on the back of the alarm. Once the cover is removed, you will see the old battery. Carefully remove the old battery by pulling it straight out of the compartment.

Locating the Battery Compartment

Locating the battery compartment of your First Alert smoke alarm might differ depending on the specific model you have. Generally, it is found in one of the following areas:

1. **Front of the Alarm:** Look for a battery compartment cover or door located on the front of the alarm, often near the bottom.

2. **Back of the Alarm:** Remove the alarm from its mounting bracket and check the back side for a battery compartment cover or door. It might be secured with screws or tabs.

3. **Inside the Alarm:** If the battery compartment cannot be found on the front or back, you might need to open the alarm housing by removing the screws or release mechanism. Be careful to follow the manufacturer’s instructions to avoid damaging the alarm.

Here is a table summarizing the locations of battery compartments in different First Alert smoke alarm models:

Inserting the New Battery

Step 1: Open the battery compartment. Locate the battery compartment on the back or bottom of the smoke alarm. Use a screwdriver or coin to open the compartment door.

Step 2: Remove the old battery. Disconnect the battery terminals by gently pulling on the wires. Make sure not to touch the exposed wires with your bare hands.

Step 3: Insert the new battery. Align the positive (+) and negative (-) terminals of the new battery with the corresponding terminals in the battery compartment. Gently push the battery into place until it clicks or snaps.

Step 4: Secure the compartment. Replace the battery compartment door and secure it with a screwdriver or coin. Verify that the battery terminals are firmly connected and that the compartment is tightly closed.

Additional Tips:

• Never use rechargeable batteries in smoke alarms.
• Replace the battery in your smoke alarm at least every 12 months, or more often if the alarm chirps frequently.
• Test your smoke alarm monthly by pressing the test button.
