What is the lifespan of a Kidde smoke alarm?

The lifespan of a Kidde smoke alarm varies depending on the model. Generally, smoke alarms have a recommended lifespan of 8-10 years. Kidde, a trusted brand in fire safety, designs their alarms to meet or exceed industry standards. Some of their models feature a 10-year sealed lithium battery, providing continuous protection without the need for battery replacements. These alarms have a built-in end-of-life indicator, notifying users when it's time for a replacement. For traditional models with replaceable batteries, Kidde recommends replacing the batteries at least once a year and the entire smoke alarm every 8-10 years. It's important to regularly test smoke alarms and follow the manufacturer's guidelines to ensure optimal performance and safeguard against potential fire hazards.
