Review: It works - So far so good, I just swapped out the batter on my Sony xb-21 and it works. All plugs fit correctly and power the speaker. I have had this speaker for 4+ years and beat it to death. After taking it apart and replacing the battery I wouldn’t trust it to be waterproof any longer. But for $20 if I get another year or so out of it I’d be happy Edit: update after 5 months still going strong. Stays charged and plays music for a decent amount of time considering it is an off brand replacement. ## Features - High quality replacement battery for Speaker - All batteries are Certificated with ISO9001, RoHS, CE, UN38.3, and MSDS - Battery Specifications - Capacity: 3000mAh, WH: 11.34Wh, Type: Li-ion, Voltage: 3.78V - Dimensions: 68.6 x 20.0 x 20.0mm Weight: 76.4g - Please ensure both model and battery part number are matched with your device.
