Anker products.
As you note, the problem with batteries is there's just so much undifferentiable import crap. Lots of it has fancy packaging.
Anker is no doubt trafficking in generics as well, but they do have their own design department (even goods like their Qi chargers that are made out of glass and metal have logos embedded in them and don't look like everyone else's generics) and when I posted a lukewarm review on Amazon ("Seems to work, nothing impressive, but good that it works.") about a phone battery, a rep with native English contacted me immediately and asked if there was anything they could do or offer to improve my experience from lukewarm to stellar.
So that at least is indicative of a company that cares. Note that I don't work for Anker, but since that experience (the phone battery was my first purchase of their products) I've purchased a number of subsequent products and none of them performed more poorly than the original OEM equipment, so that's at least something in this world of mostly fake batteries.
