"you can only extract 20% of their capacity from them before you damage the battery by sulfating the plates."
You're confusing two issues, I think. Sulfation happens if a lead acid battery is kept in a (partially) discharged state for too long (weeks). That will happen with deep-cycle batteries as well.
The issue with starter batteries is that the plates are thin and tend to crumble during a deep discharge, when a large fraction of the lead plate is electrochemically converted.
Get off the soapbox. We have no moral superiority, and we don't even rank that high in freedom of the press. We're below the UK FFS.
Funny. Years ago I thought I remember research that said the reverse. Can't find it though - Google seems crappier nowadays (you just get zillions of hits for the 2014 item).

So maybe the particular mouthwash used was bad?
"Death is wrong" is still stupid though. This is a nongeek/nerd article. Because any geek who knows his/her science knows what forever means AND thus logically won't want to live forever AND thus at a certain point Death is Right.
0) I doubt people are psychologically able and stable enough to _enjoy_ a mere billion years of existence. A thousand years, ten thousand years, maybe. But a billion? Now guess how long is forever. So many can barely tolerate a single day of no Internet access
1) How many stars are going to last forever? What are you going to do when the last ones in your range die?
2) I doubt you want to live so long that this becomes very personally relevant: https://en.wikipedia.org/wiki/...
When I posted a comment on this sort of thing before, someone basically said we all know what living forever means, you don't have to tell us. But this whole "death is wrong" story is evidence that not all of us do.
Lastly, "May you live forever" would be a pretty scary witchdoctor curse if it worked, maybe someone should write a sci-fi horror story... I'm a crap writer tho.
Behind every great computer sits a skinny little geek.
