Eh, I think it depends on how the technology advances and if the battery remains a primary feature going forwards. We already have lots of battery powered devices and device consumption of battery energy could just as easily become the place to optimize. It's the primary hurdle now for EVs, but when people swap the AAs in their devices, I hardly can imagine anyone feeling as if they're degrading the product. I imagine in this scenario, quality control and branding would still play a pretty big part of the process as well.
