After the FTC scrutiny about anti-competitive monopoly behavior Amazon themselves shut down thousands of Amazon Basics product lines on their site. We bought it and have listed many items on Racktodoor, Woot, eBay, and 50+ other channels.
Here are a few articles about it if you want to read more:

Amazon has not sold 12 packs of these in like two years!
https://www.amazon.com/AmazonBasi...B0
Remember when Amazon was closing warehouses in Q3/Q4 of 2022? They were selling these 9Vs and I bought an 8-pack back then for a crazy good deal. I bet some flipper loaded up and just realized their stuff is partially expired now and they want to dump it. That's my guess anyway.
I should note that even if these have been sitting around on a shelf for two years, it's still a good deal. The problem is we don't know how long, and if it's been more like four or five years, then that's totally different.
Q. Do you recommend using 9-volt lithium batteries to replace standard batteries in smoke detectors so that the replacement cycle can be extended?—William P. Bivins, Greenville, NC
A. Lithium 9Vs aren't recommended for smoke detectors unless you follow a strict battery replacement schedule. Those batteries maintain a high voltage until the end of their usable life, so they provide a much shorter "low battery" warning to alert you that it's time to swap in a fresh one. Alkaline batteries, by comparison, have a more gradual voltage drop-off, prolonging the "low battery" alert and greatly increasing the odds that you'll be nearby to get the alert.
​
But we change yearly, so should be OK. Price is close to Alkaline Sales.

If I look at Lion voltage drop off, it seems to go below 2.9V at about 96% discharge, I think my alkaline chirp when they are at ~8.7V, so 2.9V is the equivalent single cell voltage . If Lithium lasts ~6 years, that's about 0.3 year or ~4 months worth of chirping left. I think I'd notice that in a hurry!
I'm not quite following what you're explaining, but I'll point out that lithium batteries have a much flatter voltage curve than alkaline, which is why in some devices an alkaline will stop working even though it's barely used.

Really you are just better off buying the smoke detectors with the built in 10 year battery.
Since smoke detectors should be replaced every 10 years, since the unit itself also have a shelf life.
