Answer:

please mark me brainlist

Explanation:

As much as we would like it to be otherwise, electronic devices are not invincible. Batteries can die, and other parts of the device can wear out over time.

You’ll want to regularly check your detectors and replace their batteries, or in some cases the entire device. Doing this ensures that your family will stay safe if there ever is a fire in your home.
