Yeah, every time I visit LifeHacker it seems to be the semi-clueless leading the mostly oblivious. Maybe there's better stuff hidden away, but I haven't found it yet. Too bad, it's a great concept.

Clearly, the writer clearly doesn't have the foggiest notion about anything prior to lithium rechargeables. ("Dude, that's so 2012.")

In fairness, though, the article if focused on lithium rechargeables. The data is from Battery University, which is a credible source worth referring to. Whether that data is 100% applicable to lithium polymer batteries (vs. the lithium ion 18650s in my laptop) is a good question. The writer does not appear to have considered this. And he should have. Details matter.

EDIT: Good Lord, am I turning into one of the grumpy old guys in the Muppets' balcony??!!
