Your smoke detector is a crucial safety device that can save your life and the lives of your loved ones in the event of a fire. However, even the most reliable smoke detector is useless if its battery is dead. That’s why it’s important to know how to change the battery in your smoke detector, and to do it regularly. Fortunately, changing the battery in a First Alert smoke detector is a quick and easy process that anyone can do.
The first step is to locate the battery compartment. On most First Alert smoke detectors, the battery compartment is located on the back of the unit. Once you have located the battery compartment, use a screwdriver to remove the cover. Inside the battery compartment, you will find one or two 9-volt batteries. Remove the old batteries and replace them with new ones. Be sure to insert the new batteries in the correct orientation, as indicated by the positive and negative terminals in the battery compartment.
Once you have replaced the batteries, close the battery compartment cover and replace the smoke detector on its mounting bracket. Once you have replaced the batteries, it is important to test the smoke detector to make sure that it is working properly. To test the smoke detector, press the test button. The smoke detector should sound an alarm. If the smoke detector does not sound an alarm, check the batteries and make sure that they are installed correctly. If the smoke detector still does not sound an alarm, it may be time to replace the smoke detector.
Identifying the Battery Compartment
The battery compartment in a First Alert smoke detector is typically located on the back of the unit. It is usually covered by a small, plastic door that must be opened to access the battery. To open the battery compartment door, locate the small indentation on the bottom of the door. Use a fingernail or a small screwdriver to gently pry the door open.
Once the battery compartment door is open, you will see the battery. The battery is usually a 9-volt alkaline battery. If the battery is dead, it will need to be replaced.
To replace the battery, simply remove the old battery and insert a new one. The positive terminal of the new battery should be facing up. Once the new battery is in place, close the battery compartment door.
| Step | Instructions |
|---|---|
| 1 | Locate the small indentation on the bottom of the battery compartment door. |
| 2 | Use a fingernail or a small screwdriver to gently pry the door open. |
| 3 | Remove the old battery from the compartment. |
| 4 | Insert a new 9-volt alkaline battery into the compartment. |
| 5 | Close the battery compartment door. |
Removing Old Battery
Changing the battery in your First Alert smoke detector is a simple and important task that should be done every year. By following these steps, you can ensure that your smoke detector is always working properly and keeping you and your family safe.
1. Locate the battery compartment.
The battery compartment is typically located on the back or side of the smoke detector. On First Alert smoke detectors, it is usually secured with a screw or latch.
2. Open the battery compartment.
To open the battery compartment, use a screwdriver to remove the screw or use your fingers to slide the latch to the side.
| Type of battery compartment | How to open it |
|---|---|
| Screwed battery compartment | Use a screwdriver to remove the screw |
| Latched battery compartment | Slide the latch to the side |
3. Remove the old battery.
Once the battery compartment is open, remove the old battery by gently pulling it out. Be careful not to touch the terminals of the battery with your fingers, as this could cause a short circuit.
Now that you have removed the old battery, you can proceed to install the new one.
Inserting the New Battery

Checking the Smoke Detector’s Life
Smoke detectors have a limited lifespan. Most models last for 10 years, but some can last for up to 15 years. It’s important to check the smoke detector’s life regularly to make sure it’s still working properly. Here are the steps on how to check the smoke detector’s life:
- Check the smoke detector’s user manual. The user manual will tell you how to check the smoke detector’s life.
- Look for a date code on the smoke detector. The date code is usually found on the back of the smoke detector. It will tell you the month and year that the smoke detector was manufactured.
- Subtract the smoke detector’s age from the present year. This will tell you how much life the smoke detector has left.
- If the smoke detector is 10 years old or older, it’s time to replace it.
- If the smoke detector is less than 10 years old, you can continue to use it. However, you should check the smoke detector’s life regularly to make sure it’s still working properly.
- If you have any questions about checking the smoke detector’s life, consult with a qualified electrician.
Here is a table that summarizes the steps on how to check the smoke detector’s life:

Troubleshooting Common Battery Issues
Dead Or Weak Battery
If your smoke detector is beeping once every 30-60 seconds, it’s likely that the battery is dead or weak. Replace the battery with a fresh one of the same type and voltage. Make sure the battery is installed correctly, with the positive and negative terminals aligned properly.
Damaged Battery Contacts
If you’ve replaced the battery but the smoke detector is still beeping, the battery contacts may be damaged. Remove the battery and inspect the contacts for any corrosion or debris. Clean the contacts with a cotton swab dipped in rubbing alcohol and insert a new battery.
Loose Battery Connection
Ensure that the battery is securely connected to the contacts. If the battery feels loose, try twisting it slightly to tighten the connection. You can also try inserting a small piece of paper or cardboard under the battery to create a tighter fit.
Incorrect Battery Type
Double-check that you’re using the correct battery type for your smoke detector. Refer to the manufacturer’s instructions to determine the specific battery type required.
Damaged Smoke Detector
If you’ve tried all of the above troubleshooting steps and the smoke detector is still malfunctioning, it’s possible that the smoke detector itself is damaged. Replace the smoke detector with a new one.
Electrical Problems
In rare cases, electrical problems can cause the smoke detector to malfunction. Check the wiring connections for any loose or damaged wires. If you’re not comfortable working with electrical wiring, contact a qualified electrician.
Radio Frequency Interference (RFI)
Radio frequency interference (RFI) from other electronic devices, such as cordless phones or microwaves, can sometimes interfere with the smoke detector’s operation. Relocate the smoke detector away from any potential sources of RFI or try using a different frequency for the interfering device.
Safety Precautions When Changing the Battery
Before you begin, ensure you have the correct battery type for your smoke detector. The battery type will be specified in the user manual or on the back of the smoke detector.
Once you have the correct battery, follow these safety precautions:
-
