What type of battery do Kidde smoke alarms require?

Kidde smoke alarms typically require either a 9-volt battery or lithium batteries, depending on the specific model. Many Kidde smoke alarms are designed to run on a 9-volt battery, which is easy to replace and widely available. Some of Kidde's newer models may utilize long-life lithium batteries that are designed to last for several years, reducing the need for frequent replacements. It is essential for users to regularly check the battery status and replace the batteries as needed to ensure the smoke alarm functions correctly. Additionally, some Kidde smoke alarm models may be hardwired into the home’s electrical system, which could also include a backup battery for added security in the event of a power outage.
