Electronics360: "Identification of counterfeit electronics"

'Battery bloat', as shown in the illustration, is a normal thing for lithium ion batteries.

I've had it happen to a Samsung phone purchased new from a Verizon store, as well as a Microsoft Surface Pro 4 computer purchased new from Best Buy. In fact, I've got the computer apart right now and I'm in the process of replacing the battery in it.

While I'm not a fan of either Verizon nor Best Buy, I don't think they would stoop to selling counterfeit products.
