The battery in my apple remote fails to hold a charge more that 4 hours unplugged. so I figure needs new one. The remote is from a 4th gen apple tv, but the remote may be 1st gen? any how the info I have is off battery A519 Li-ion 3.78v 410 mAH 020-8476 It has two solder on tabs on two corners, close to them. Apple says its not replacable. I have the remote apart. But I stopped to see if battery available before I go any further I hope one is available I had purchased A battery for my old iPhone 6 and it worked great, until phone itself went wonkie
