Introduction

If your Anker Soundcore Select Pro A 3126 is not holding a charge or turning on momentarily, then turning off, it may be due to battery deterioration. As a result to repeated charging cycles, your battery loses its ability to properly hold a charge. Use this guide to replace your battery.

If you notice your battery looks swollen, puffy, emitting smoke, or smells funny. Proceed with caution, for a swollen battery poses a serious fire hazard and should be handled with extensive care.

Make sure your speaker is fully powered off and disconnected from the charger before beginning the battery replacement or working with any internal components.

Using a spudger, pry open the front half of the speaker.
The front and back halves of the speaker are connected by several cables. Open the speaker slowly and avoid pulling on the cables, as they can be damaged easily.

Step 8

Using a Phillips #1 screwdriver, remove the two 12.5 mm screws securing the motherboard to the speaker.
Remove the motherboard from the device.
Remove the two 9.0 mm battery screws to separate the battery from the motherboard.
Use the point of a spudger to push on alternating sides of the connector to "walk" it out of its socket to disconnect the battery connector from the motherboard.
It may take a lot of alternating before the connector comes out. Be patient, and don't pull on the cables.
If the connector doesn't release using the spudger, use a pair of tweezers to firmly grip the sides of the connector and pull straight away from the socket.
If you're having trouble, try rocking the connector side-to-side to loosen it.
