What could be a consequence of not replacing smoke detector batteries regularly?

Not replacing smoke detector batteries regularly can lead to an increased risk of malfunction. Smoke detectors rely on batteries to function effectively, and a dead or weak battery may prevent the device from sounding an alarm during a fire. This malfunction could result in a failure to detect smoke or heat, directly impacting the safety of occupants in the building. Regularly replacing batteries ensures that the smoke detector operates optimally and continues to provide the crucial early warning needed to evacuate and respond to fire emergencies safely.
