In The Villages, the type installed by the builder are not sealed. The batteries are replaceable. If you replace the alkaline battery with a lithium battery, then you essentially have a 10 year smoke detector, that will function just like the sealed units. By code, sealed units are only required when you are adding a smoke detector in a remote location where the detector is not connected to the house electrical system. My point is that there is no need to replace the non-sealed detectors with the sealed type. Just replace the battery. If you want it to last 10 years, then use a lithium battery.
