How Often Should I Change the Battery in My Smoke Detector?

Richard Erickson • June 14, 2024

Smoke detectors in your home are key to ensuring the safety of your family and property. Having smoke detectors placed around your home is one thing, keeping them in working order is another.

It’s critical to keep your smoke detector battery working to protect your household. Here are some things you should know about the battery in your smoke detector.

How Often Should I Change the Battery?

As important as it is to change the battery in your smoke detector at regular intervals, it’s equally important to test your detectors to make sure they are working. First Alert states that you should test your smoke alarms once a month. They also say that if your smoke detector is powered by a nine-volt battery, it should be replaced every 6 months. We recommend when you change your clocks for daylight savings to help you remember.

The smoke detector itself should be replaced at least once every ten years.

If you have a lithium-powered smoke detector, you will need to replace the entire device every ten years.

Signs that you need to replace your smoke detector’s battery before six months include:

  • It chirps non-stop. Chirping repeatedly is a sign the battery is low and needs replacing. Don’t ignore a chirping smoke detector.
  • Monthly testing fails. While it may be inconvenient to change the battery more often than you expected, don’t procrastinate.

Changing the device itself may be required before its ten years are up if:

  • The smoke detector goes off for no reason. The devices can become more sensitive as they age.
  • It’s been recalled. If the device itself or any part of it has been recalled, it’s time to get a new smoke detector to ensure your device is functioning properly.

What About My Wired Smoke Detectors?

Wired smoke detectors do not have their own batteries. Rather, the control panel for the security system they’re tied into has a backup battery. This way, when the electricity in your home goes out, your system components can continue protecting your home (for a period).

What to Know About Hardwired Smoke Detectors

Hardwired smoke detectors are connected to your home’s power supply, which means that if the power goes out, so will the power to your smoke detector.

The backup battery in your security system’s panel will continue to power the system for a period of time (usually around 24 hours, but it varies depending on the complexity of the system). If that battery dies, your home will be unprotected.

Power must be turned off for maintenance work on the wired smoke detector, which can be inconvenient. Overall, a little more work goes into hardwired smoke detectors, from professional installation to maintenance, but this isn’t a bad thing!

Hardwired smoke detectors are interconnected, meaning all the devices on the same wire will sound when one does. This alerts everyone inside the property and enables them to leave the house immediately.

According to Forbes Home, local codes for new construction are increasingly requiring hardwired smoke detectors because they are so effective.

Whether you use a battery-operated smoke detector or a hardwired one, checking the health of and replacing the battery is important. A working battery means protection for your family.

The Importance of Home Security Systems During the Holidays

By Richard Erickson • November 25, 2024
The holiday season is a time for joy, family gatherings, and festive celebrations. However, it is also a peak time for home burglaries and security threats. With homes often left unattended during travel or bustling with activity, the need for a robust home security system becomes more critical than ever. Here’s why investing in or upgrading your home security system should be at the top of your holiday checklist.  Increased Risk During the Holidays Vacant Homes : Many families travel during the holidays, leaving their homes vulnerable. Burglars are often on the lookout for signs of an empty house, such as accumulated mail or a lack of lights. Busy Schedules : The hustle and bustle of the season can lead to lapses in routine security measures, like locking doors or securing windows. Package Theft : With the rise of online shopping, packages left on doorsteps are a common target for thieves. Porch piracy spikes significantly during the holiday season. How a Security System Protects Your Home 1. 24/7 Monitoring Modern security systems offer round-the-clock monitoring, ensuring that your property is protected whether you’re at home, out shopping, or traveling for the holidays. Professional monitoring services can alert authorities immediately if an issue arises. 2. Smart Technology Integration Smart home security systems allow you to control and monitor your home remotely. Features like live video feeds, motion detection, and smart locks give you peace of mind and control no matter where you are. 3. Deterrence Factor Visible security cameras, alarm systems, and yard signs act as powerful deterrents to would-be burglars. Most intruders will avoid homes with evident security measures. 4. Protection for Deliveries Video doorbells and motion-activated cameras can help you monitor deliveries and deter package thieves. Many systems also allow two-way communication, enabling you to address delivery drivers or suspicious individuals directly. Additional Tips for Holiday Home Security Automate Your Lights : Use smart plugs or timers to create the illusion of an occupied home, even when you’re away. Secure Entry Points : Reinforce doors and windows with locks and sensors that trigger alerts if tampered with. Keep Travel Plans Private : Avoid posting travel details on social media to prevent broadcasting your absence. Alert Neighbors : Inform trusted neighbors of your travel plans so they can keep an eye on your property. Peace of Mind This Holiday Season The holidays should be a time of joy, not worry. A comprehensive home security system provides more than just protection; it offers peace of mind.
