## Product: Duracell Coppertop 9V Batteries (4-Pack)
**Brand:** DURACELL

Yeah, Duracell Coppertop 9V batteries are a solid choice for smoke detectors. From what we've gathered, they have a good track record for delivering consistent power, which is pretty important for critical devices like smoke detectors and carbon monoxide alarms.

Duracell says these batteries can last up to five years in storage if you keep them well, so you don't have to worry about them losing juice if they're sitting around for a while.

People seem to trust them—they're known for being durable and dependable. 

Even though sometimes the packaging might not have the freshest date printed, our research shows they tend to work just fine in smoke detectors. The long shelf life is a big plus if you're using them for emergency power, which means less worrying about changing them out all the time.

If you need to know the exact expiration date, just double-check with the seller or take a look at the packaging when you get them. Duracell does offer a warranty for defects, so that should ease any worries about shelf life or the battery not lasting as long as expected.

Overall, these batteries are reliable and give you the consistency you'd want for keeping your smoke detectors powered up.
