Even though that thread expired the price stayed the same. I bought it several times for this price between now and then.

It has 10 year shelf life. It's hardly a clearance.

Thats my point, they are advertised as 10 year shelf life and expire in 2030.

One thing to keep in mind is that Lithium battery power levels drop very quickly when the battery is getting weak. This is unlike Alkaline batteries that have a more gradual curve. As a result, this is NOT recommended for smoke/carbon monoxide alarms or any electrical devices that provide a warning chirp when the battery is getting weak. The nagging chirp is important to make sure you replace the battery. With a Lithium battery, you might hear the chirp a few times and after that the device is dead which will give you a false sense of security.

This battery will outlast a smoke alarm. You would need to replace a smoke alarm before the battery goes dead. Some smoke alarms are now sold sealed with batteries like this (in a different shape maybe). Smoke alarms have expiration dates and I believe they chirp when this date comes.

I don't understand your point. Stuff can be sold before the expiration date. So these can be sold for 9 years from now. Shelf life is not usage life. So, these can be used in 10 years after manufacture and still last for as long as they last after 10 years on the shelf. People buy things to use, not to store them for 10 years before use.

Smoke alarm is what I buy this for. It save me from climbing up there to change it ever year. Even though might only get 5 years out of it, I'm good with that. How much is the regular alkaline cost already? take that and lets say multiply it by 5. I'm just using 5 years as a minimum life span and never mind about the 10 years.

What is the basis of this? I would think this depends on the power consumption of the smoke alarm. Usually the battery of smoke alarm is recommended to be replaced twice a year.

Shelf life just means how long you can store them before you should start using them. Basically by 2030, the battery is not guaranteed to have 100% capacity. So even if you start using it at 2030, it may still have 90% of its rated capacity.

These lithium batteries are very hardy. Somebody measured a set after 15 years and they were basically as good as new.

FYI, this is only a smoke alarm, It doesn't have carbon monoxide detection.

Which is fine by me. I don't have gas appliances and my car is electric!
