Are products marketed as for Lead Acid batteries worth my time?

I have on hand the 2 batteries shown below They both show no voltage on the bench dmm.

There are a number of units on Amazon labeled as desulfators. Are any of them worth my time? What's the minimum I should expect to pay? Any specific brands?

How long should I expect to wait for results with a unit that "works"?

Wikipedia seems conflicted on this topic. Specifically, it explains the operation but also says there is no peer reviewed research to support it.

Thanks so much

Lead-acid batteries are completely recyclable, therefore they have scrap value.
Lithium ion batteries are almost impossible to recycle, so you are charged to dispose of them.
