Don’t bother changing your smoke detector batteries until you’ve tested your smoke detector. We’ve got a step-by-step of how to do that here.

Well, the smoke detector fairy won’t be showing up to do it for you. If you don’t regularly test and change your smoke detector batteries, you’re playing with fire (pun intended). Your smoke detectors will eventually stop working, or they will be so low on battery that if the alarm goes off, the beeping sound may be too quiet for you to actually hear it.
Smoke detectors should be a “sure-thing” in your home. You shouldn’t be wondering whether or not the battery is dead or almost dead, and you shouldn’t be wondering if they are functioning correctly. Take the time to get to know your smoke detectors, figure out how they work, and keep fresh batteries in them. It’s just not worth the risk. (Did we mention it only takes five minutes?)
