Yes and no.
As I stated previous, build quality regarding things like connectors, housings, wires, or even the construction of the cells themselves can be a deciding factor - and most people know what the premium brands are (Sanyo for instance). What I am referring to is when battery manufacturers themselves make claims beyond that regarding battery technology itself and how their brand is superior, leaving the consumer with the impression that their battery is somehow chemically and therefore electrolytically superior to another which simply isn't true.
