I have some of the old school ones, which are “test every 6 months, replace every year,” but also a fancy schmancy lithium ion-powered one that should be good for 10 years (so test every 6 months, but replace after 10 years).

Yea the lithium-ion batteries are pretty good, you can also get 10 year smoke detectors with a built in lithium battery. Also a psa, smoke detectors usually only last 10 years and need to be replaced after that. There’s often an expiry date on the detectors.
