New Standard Horizon FNB-80LI Replacement Battery f/HX471S
From the back of the radio it looks like an OEM battery, But it is labeled \\"Battery Jack\\" brand and has no matching numbers or Yaesu or Vertex logos anywhere. States \\"Genuine Yaesu Vertex-Standard Product\\" on the web page but shows no evidence of that when you have it in hand. It does power up my radio and appears to charge, time will tell if it's actually any good.
