Replace your smoke detectors

No, not the batteries. The whole smoke detector. Yes, all of them.

They’ve got a useful life span of about ten years. Smoke Detector Life Expectancy – Consumer Reports. And unless your house is less than ten years old, you’ve never replaced them.

And you’re supposed to test them once a week. You do test them once a week, right? Yeah; me, either. I replaced six and two of them were completely inoperable.

And they’re inexpensive. The new ones have a ten year battery! Cheap 9-volt batteries are about $2 each; I got six First Alert alarms with ten year battery backup for $62.

Replace your smoke alarms, and save money. And maybe someone’s life.
