Multiple normal charge and discharge cycles are required to activate the battery and restore normal capacity.  ②When the speaker is charging the battery, it needs to be charged at an ambient temperature between 5 °C and 35 °C, otherwise the charge indicator will go out, causing the battery to fail to charge.  ③When the speaker is not used for a long time, it takes a long time to activate your machine to activate the battery self-protection state. Only after breaking through this state can the battery be charged and used normally.  ④Before the speaker needs to be charged, do not expose the speaker to rapid temperature changes, direct sunlight, or moisture, which may cause the battery to be damaged in high temperature or humidity and fail to charge.

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. 🙁 Review: 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. ## Features - Excellently Compatible : Suitable for So-ny Speaker SRS-X77, SRS-BTX300, SRS-X55 - Battery Specification : Voltage:7.4V, Capacity:2600mAh/19.24Wh, Size:131.20 x 21.30 x 18.60mm, Weight:234.5g - Prompt Before Use : Please allow enough time for charging the battery before using it.
