SRS-XB22 Battery Replacement

Firstly, you need to pry the speaker grill away from the speaker.

Use a spudger/guitar pick to prise up each end of the grill.

You are trying to lift a clip at either end. (circled in red)

Once lifted at both ends, gently pull the grill forwards.

Completely remove the grill.

Remove the 8 screws that hold the speakers in place.

Slowly pull the speakers forward to free them from the case.

Disconnect the speaker cables from the internal circuit boards.

Be careful, the sockets are easy to damage

Remove both of the rubber gaskets from the case - one for the left speaker, one for the right.

Starting at the ends of the speaker, prise the back case away from the main unit.

Work your way along the front of the case.

Once the front in freed, work you way along the edges, freeing the whole case.

There is A LOT of double sided tape between the outer and inner case. It requires a lot of work to remove it.

The case is one piece. Although it looks as if it splits at the rear, it is sealed together.

Remove the rear outer casing of the speaker.

Remove 3 screws at either end of the speaker, so 6 screws in total.

Using a spudger, unclip the top and bottom plastic clips, holding the front of the speaker.

(I made the error and removed the illuminated surround, hence it is not in two of my pictures here - it is NOT necessary to remove it)

Slowly pull the front panel forwards.

Be careful, there are 3 wires still connected.

Disconnect the three wires, freeing the front panel.

Lift the rubber gasket away from the unit.

Locate the 6 screws holding the internal structure in place.

Remove these 6 screws.

Use a spudger to lift the button away from the speaker.

Be careful, it's held down by more sticky tape!

Slide the main plastic unit forward from the speaker.

There will still be a couple of circuit boards in the back that are connected. These are the boards for the rear panel.

Disconnect the battery lead from the circuit board.

Carefully, pull the battery out of its recess.
