I recently learned that the new battery operated smoke detectors come with lithium batteries that last 10 years, so you don't have to change the batteries every spring and fall anymore if you have these new ones.
Apparently the hardwired units must be replaced every 10 years as they don't last forever. They may not be detecting smoke properly after that.
Were you aware of all this?
