Rechargeable LI batteries are usually 3.6V cells with a voltage regulator whereas non-rechargeable LI batteries are a native 1.5V cells. The former might have unexpected limitations such as limited max current or lower overall capacity.

Seems like a waste of lithium for a slightly longer battery life

These have a role for things like water sensors, temperature sensors, anything in a hard to reach place that you don't want to replace often. They're also the best performing batteries in extreme temperatures. I have sensors on my water meter and in the crawlspace that I use these for. Moving to rechargeables for pretty much everything else.

Must have for Blink cameras or other devices that are hard to reach such as automated blinds.

Showed $7.12 for me but I already have 48 from one of the last deals.

It's still wasteful.

The people that should buy these are people that have devices that need a stable 1.5v cell even under high load or need their batteries to operate in very cold temperatures.

A lot of people buy these for their Blink security cameras which are incredibly sensitive to voltage sag, live in extreme temepratures, and are expected to last for long periods. There are rechargeables that work with them, but its hard to find ones that work well and the cameras don't accurately warn you when the batteries are low like they do with these.
