Crazy question: Where can I buy a GENUINE Note 4 OEM battery?

[AC Question]

Spent the past 4 hours browsing the internet, continuously striking out. 100% of he batteries on amazon/ebay are fake. Is this what you get buying a samsung phone? A year later your S.O.L.? You should get at least 3 years of use out of a $700 phone IMO. Does anyone have some magical soruce (I already know the answer is no) or an idea or anything? Not interested if it's not OEM or genuine. This is a serious problem I see for samsung phone owners. Thanks upfront
