### ⭐⭐⭐ Not pin compatible
*by M***E on January 26, 2024*

While this battery works as a replacement for the battery in a Perytong Sleep Headphone set, it lacks the 3rd wire present on the OEM battery which apparently provides power to the “battery full” indicator LED. There’s no way to tell when the battery is full and should be disconnected from a charging circuit.
