Kidde Fire Sentry Smoke Detector Battery Replacement

はじめに

If your Kidde Fire Sentry Smoke Detector is beeping intermittently or if it has been six months since the last battery change, it’s likely time to replace the battery.

A working smoke detector is essential for early fire detection and can save lives. Most smoke detectors are designed to emit regular beeps when the battery is low, signaling that it's time for a replacement. Even if it isn’t beeping, the battery should be replaced every six months to ensure proper function.

Before beginning the replacement process, make sure to have a 9V battery on hand. This guide demonstrates how to replace the battery in a Kidde Fire Sentry Smoke Detector, though similar steps apply to many other models and brands.
