Check Your Batteries

The time is coming again to check your smoke detectors, “Fall back, and Spring Ahead.” Batteries should be replaced at least once a year or whenever the low-battery indicator sounds. Conventional smoke alarms should be replaced every 10 years too. If you have a lithium battery, they should last 10 years.
