Not delivered fitting SRS-X77
I got a refund today. Ordered this for a SRS–X77. The advertising says it fits this device. In the picture, the connector has 5 pins. As delivered, it only had 3 pins. It would run the device, but it would not charge. & it was about .25“ too long to fit into the device. 🙁

DOA battery
The battery was likely dead upon its arrival to me. It never worked, even letting it charge for many hours brought no change. I was too busy at the time of purchase (late 2024) so I missed the return window. That's on me. But the battery should have worked and didn't, unfortunately.
