2600mAh ST-01, ST-02 Battery Replacement Compatible with Sony SRS-XB2, SRS-X3 Wireless Portable Bluetooth Speaker with Installation Tool

I have a Sony Bluetooth speaker that I use a lot and I’ve had it for years. The battery that it came with still works but it does not hold a charge for very long. I bought this battery as a replacement. There are no instructions for how to put it in the Bluetooth speaker so I had to watch videos on You Tube to figure it out. Once I saw how to do it, it was easy to take out the old battery. It was a bit tricky to get the new battery in the speaker and get the bottom plate back one so it is level but I figured it out. The new battery works just as well as the old one and seems to hold a charge for a normal amount of time. It still takes about 5-6 hours to get it to full charge. But I am happy that all I needed to buy was an inexpensive battery to be able to keep using my Sony Bluetooth speaker and not have to buy a new one.
