I like the device having an indicator stating that it needs to be replaced. To often I see detectors that are beyond yellowing and they are still in service.
It's smart of you to replace them, many people don't, I myself need too.

I bought a CO detector about 20 years ago for $32. When the detector signaled that it needed attention, I replaced the standard 9-volt battery. In addition, the detector's instructions directed the purchaser to replace "The Module"—from the manufacturer—
at $40!
I yanked "The Module" out, and pried open its seal: inside was a
second standard 9-volt battery.
