Battery powered smoke detectors have a useful life of 10 years...not the batteries, but the unit itself and its ability to detect smoke particles.
We moved into our home in 2010 and I've been meaning to check the age of our smoke detectors, not just throw new batteries into them. Sure enough, the previous homeowner replaced them around 2009 and I should have done so back in 2019. Off to The Home Depot for some replacements.
For your own safety and the safety of those you love, please remember to check the date on your smoke detectors!
