How to Replace Batteries in SimpliSafe® Devices
Updated
With the exception of the Base Station, SimpliCam Indoor Camera, Smart Alarm Indoor Camera, and Key Fob, all of the components for our latest SimpliSafe have batteries that can and should be replaced periodically. When a sensor needs new batteries, your system will display an error message on the Keypad.
The Base Station requires specific rechargeable batteries; and the SimpliCam Indoor Camera only functions when connected to power, rather than being battery operated. The Smart Alarm Wireless Indoor Security Camera has non-replaceable batteries within it, and can be used on battery or plugged into a power outlet.
Finally, the battery within the Key Fob cannot be replaced. If you require assistance with your Key Fob, please contact support.

To charge your battery, you’ll need a USB-supported power brick that supports 5V, 7.5W+, 1.5A+ charging. Using the supplied cable, plug it into the power brick and the camera and charge your battery. To fully charge your battery, it can take up to 5 hours. You’ll know the battery is fully charged once all 3 lights are illuminated and no longer pulsing.
To replace your battery, slide it back into the battery compartment in the Outdoor Camera with the tab facing outwards. Then, twist the cap back onto the Outdoor Camera until you hear it click.
Still Need Help?
If the battery for your SimpliSafe® product was recently replaced, it can take up to 21 hours for the low battery or offline warning to clear. You can bypass this time frame with the following steps:
Using your Keypad, press the Menu button
Enter your Primary PIN
Scroll until Test Mode is highlighted
Use the right arrow and tap to the right to enter Test Mode
Locate the test button on your SimpliSafe® device and press it three times
This will cause the device to check back in with the Base Station and should clear the low battery or offline warning
If those steps do not work, we recommend removing the camera or sensor from your account and reinstalling it using the corresponding installation guide on our Help Centre.
