What Battery Does the SimpliSafe Glass Break Sensor Use?
The SimpliSafe Glass Break Sensor specifically uses a CR123A lithium battery. This is a common size for many security devices, cameras, and even some high-powered flashlights. You’ll often see them labeled as a “123A,” “VL123A,” or “CR17345.”
Why this type of battery? CR123A batteries are chosen for several reasons:
- Long Lifespan: They are designed to last for a long time, typically 3-5 years in a low-drain device like a security sensor, depending on usage and environmental factors.
- Consistent Power: Lithium batteries provide a stable voltage throughout their life, meaning your sensor gets reliable power until the very end.
- Temperature Resistance: They perform well in a wider range of temperatures compared to alkaline batteries, which is important for sensors that might be installed in less climate-controlled areas of your home.
- High Energy Density: They pack a lot of power into a small size.
It’s important to stick to the specified CR123A battery. Using a different type might not fit, could damage the sensor, or won’t provide the correct power output, leading to unreliable performance or premature failure.
Why Battery Life Matters for Your Glass Break Sensor
The lifespan of your CR123A battery in the SimpliSafe Glass Break Sensor is primarily determined by how often it needs to “listen” and communicate. Here’s why a fresh battery is so critical:
- Constant Monitoring: The sensor is always on, listening for the specific acoustic signature of breaking glass. While it doesn’t actively transmit all the time, it requires continuous power to be ready.
- Low Battery Alerts: SimpliSafe systems are designed to notify you well in advance when a battery is running low. This gives you plenty of time to replace it without compromising your security. Don’t ignore these alerts!
- False Alarms and Connectivity: A weak battery can sometimes lead to erratic behavior. It might cause connectivity issues with your base station or, in rare cases, lead to false alarms if the sensor’s performance is compromised.
- Protection When You Need It Most: The worst time to discover your sensor has a dead battery is during an actual emergency. Regular checks and timely replacements are essential for peace of mind.
Typical Battery Lifespan and What Affects It
As mentioned, a CR123A battery in a SimpliSafe Glass Break Sensor typically lasts between 3 to 5 years. However, several factors can influence this:
- Sensor Placement: Sensors installed in rooms with more ambient noise (like near windows that are frequently opened or closed, or in very drafty areas) might process more sound data, potentially using slightly more power.
- Environmental Conditions: Extreme temperatures, both hot and cold, can affect battery performance and longevity.
- Signal Strength: In homes with weaker Wi-Fi or SimpliSafe signal strength, the sensor might need to work harder to maintain a connection, which can drain the battery faster.
- System Usage: While not a significant factor for battery sensors, very frequent arming/disarming cycles of your system indirectly signal the sensor to be more active in its communication checks.
When to Replace Your SimpliSafe Glass Break Sensor Battery
There are generally two main indicators that it’s time to replace the battery:
- System Notifications: Your SimpliSafe system is smart! It will usually send a notification to your app or keypad when a sensor’s battery is running low. This is the most reliable indicator and gives you ample warning.

It’s also a good proactive practice to note the date you installed a new battery. If you have multiple sensors, setting a calendar reminder every 3 years can help you stay ahead of potential issues before the system even alerts you.
How to Replace the Battery in Your SimpliSafe Glass Break Sensor: A Step-by-Step Guide
Replacing the battery in your SimpliSafe Glass Break Sensor is straightforward and can be done yourself in just a few minutes. You won’t need many tools, making it a DIY-friendly task.
Tools You’ll Need:
- One fresh CR123A lithium battery.
- A small Phillips head screwdriver (often not needed, but good to have just in case the screw is tight).
- A soft cloth (optional, for cleaning).
Step-by-Step Replacement Process:
Before you start, it’s a good idea to disarm your SimpliSafe system. If you’re concerned about accidentally triggering an alarm, you can also put your system into “Test Mode” via the SimpliSafe app or keypad. This will alert you that the sensor is reporting, but won’t trigger a dispatch.
-
Locate the Sensor: Find the glass break sensor mounted on your wall or ceiling. Note its position so you can re-mount it correctly.
-
Open the Sensor Housing: Most SimpliSafe sensors have a small screw on the bottom or side that holds the housing together. You may need a small Phillips head screwdriver to loosen this screw. Don’t remove the screw completely if not necessary; just loosen it enough to allow the cover to detach.
-
Remove the Old Battery: Once the housing is open, carefully remove the old CR123A battery. You might be able to gently pry it out with your fingernail or a small, non-metallic tool. Pay attention to the battery’s orientation (positive and negative ends).
-
Insert the New Battery: Take your new CR123A lithium battery. Ensure you insert it with the correct polarity. Typically, the positive (+) end of the battery should face outwards or towards the spring inside the compartment. The sensor housing usually has markings indicating the correct orientation.
-
Close the Sensor Housing: Carefully align the two halves of the sensor housing and close it. If you loosened a screw, re-tighten it securely but avoid over-tightening. If there was no screw, the housing should simply snap or slide back together.
-
Mount the Sensor (if removed): If you had to remove the sensor from its mount, re-attach it securely. Ensure it’s positioned correctly to pick up the sound of breaking glass. The optimal range for most glass break sensors is within 25-30 feet of windows.
-
Test the Sensor: This is a crucial step!
- If using Test Mode: Navigate to the sensor in your SimpliSafe app or keypad, and it should show as “Working” or “OK.”
- Manual Test: You can simulate the sound of breaking glass. A common method is to gently tap a spoon against a hard surface while standing near the sensor. The sensor should blink or give an audible chirp (depending on its settings) to indicate it detected the sound.
- System Test: If your system has a general “Test Mode,” you can activate it through the SimpliSafe app or control panel, then trigger the sensor. You should see it register as active.
If the sensor doesn’t respond, double-check the battery orientation, ensure the housing is properly closed, and try testing again. If problems persist, contact SimpliSafe customer support.
