The Tile Mate 2022 model does not have a replaceable battery.  You can open the original and use this case with a new CR2032 battery to keep your Tile working.  

When you open the old tile, pull out the board, rip the battery terminals off the battery but make sure they don't come off the circuit board. Carefully peel the speaker off the old tile and place it in this new shell.

The circuit board sits on two small pins in this case.  Press the board down to make it click into place.  Then add the battery and place the lid on the case.  It takes quite a bit of force to squeeze the case together.  This is by design to ensure the case does not fall apart after a year or two of use.  If you need to change the battery again in a couple of years, you will need to destroy this case and print a new one.

This case is approx 1mm thicker than the old case but roughly the same size in the other dimensions.  Squeezing the case presses the button on the tile.
