Quote from overzeetop :
It's a different type of battery. First, in the worst case it has about it holds about 20% more energy than an alkaline battery and about 50% more than a NiMH rechargable. In the best case, at high drain, it holds more than 200% additional capacity over alkaline (there is minimal current-dependency on discharge). It will store without leaking in an active state (zero or uA drain) for a decade. It is also nearly unaffected by temperature, from -40C to +60C when used in low drain applications (25mA) as is common for monitoring tasks. And it has a nice drain curve, with the voltage holding up above 1.4v for 90% of it's capacity all the way up to 100mA drain.

So, yes, this battery is for real. It's not for putting into a kids toy or something easily changed or changed regularly. It's great for hard-to-change locations, great for products which need long life, great for high current needs, and perfect for items which you will need powered an emergency and want to store with the batteries in-place and ready to go.

And, as SeriousSardine pointed out, Google Nest (and Blink) devices require them to work properly/efficiently.
So for 20% more capacity, you are paying 400% more.

Math

It's required in school.

At this price per battery the ROI on rechargeable Lithium batteries are probably much better in a year or two you have broken even and they hold the voltage so the squirrely products will work with this. I see many w/ longer warranty so YMMV on this, but even rechargeable Lithium batteries have doubled in price when in fact the minerals in them have gone DOWN over the last year.

Lithium spot prices are down a whopping 80% in the last year, so perhaps you may want to reconsider your statement.

So is reading.

I've had a $100 flashlight ruined by 25 cent alkaline batteries that I forgot to remove after a camping trip. These lithium primary cells, otoh, never leak have a very long (10+ year) shelf life. Put them in a flashlight in your glovebox and you can be sure it'll work fine in 6 years when you finally need it. Alkalines, otoh, will have melted your flashlight's innards. And even LSD rechargeables will have lost their charge.

I use them in various spots where a battery might last long enough to leak, e.g. my garage door keypad and my outdoor wireless temperature and humidity sensor.

Sure, they're not the best choice for your kid's toys. But they have their uses.

I for one won't order ANY Duracell or Energizer battery from Amazon anymore, lithium or otherwise. The amount of counterfeit batteries from them due to comingling stock is mindboggling.

I just stopped at a Buc-ee's today. These are ~$9 for a 4-pack. And ~$15 for 8-pack. I bought two 9V Lithiums for $12.

I hate to spend it but with Blink cameras you need a battery like this.
I've been using alkaline batteries in mine for 5 years. No problems, and decent lifespan. Only thing is the app shows low battery all the time, so you don't really know when they are truly getting low.

Tbh, these batteries will last forever. And for devices like Google nest, these are the only compatible batteries.
How long does it last though?

These are the only ones that work for the Nest Protect Battery Smoke detectors. I've tried multiple rechargeable Li Ion and after about 5 days Nest is giving me the low battery warning. I hate to buy single use but these seems to be the only ones that work.

18 pack at sams is $1.94 per battery (normal price), while this is $2.28 per. This is only a good deal if you just need a few, and if that is the case then good deal!
Do you ever see them go on sale in the store? (I've been watching for sales on Sam's Club online and haven't seen one.)

Quote from zippyd :
The price for these went way up during the pandemic because of supply chain issues leading to high lithium prices. Lithium prices recently dropped but is still double the price they were before the shortages. Prices haven't returned to pre-pandemic levels because demand for lithium usage is way up in EV's, consumer products, battery packs for homes, and electric company batteries to replace peaker power plants. To blame the price increases on inflation is misleading as price increases have more to do with increased demand without a corresponding increase in lithium production than economic inflation. Unfortunately people with low IQ's or political agenda will not understand that nuance even after receiving that information.
What the heck you talking about man. You wrote a lot of things seemingly to explain that inflation does not INFLATE prices.

Every single thing EVERY THING in this world is more expensive due to inflation. If you can't understand that simple fact but yet can state all these other economic impacts then what the heck are you about?!

You make zero sense! Not sure what other people wrote here but if anyone has a political agenda it might be you. I don't know cause I don't even know what you are about writing like inflation is not a thing. Yeah it's a made up fantasy?! What?!
