Do smoke alarms require batteries? What type of batteries are recommended?

Yes, most smoke alarms, especially battery-operated ones, require batteries to function. The batteries power the alarm and allow it to work even during a power outage. The type of battery recommended can vary based on the smoke alarm model. However, 9v alkaline batteries are commonly used. Some alarms also support long-life lithium batteries that can last for several years. It's essential to check the manufacturer's instructions for the recommended battery type and replacement schedule.
