The short answer is no, but not to be dissuaded, I opened a Tile Slim I owned that had a dead battery.

I opened my Tile Slim with a prying tool. Inside the Tile Slim, the bulk of the space is taken by a custom non-rechargeableCP114951 lithium battery. The exact battery model in the Tile Slim is:

  • Brand: Utralife
  • Model: CP114951
  • Capacity:  380wAh 3.1V

The battery is very thin, like stick of gum thin and measures (L) 51.0mm x (W) 48.75mm x (T) 1.10mm.

Inside the Tile Slim the battery is shielded by a piece of aluminum. The bulk of the internals of the Tile Slim really are the battery, aside from a small circuit board and a slim speaker.

You cannot buy a replacement Tile Slim battery as an individual. That means you cannot replace the Tile Slim battery. Even if there were replacement batteries available, the process isn’t easy.

If you open your Tile Slim, you can remove the battery. There’s some glue you need to peel back, then the battery (at least for me) just pulls out of some sockets. If you’re technically inclined, I guess you could solder a battery case and attempt to use some other kind of battery, but I wouldn’t recommend it. I’m also not sure if you could re-seal the Tile Slim case again, which is needed for the speaker.

What should you do? You’re going to have to replace your Tile Slim. Or you can go down my path and make the move to Air Tags. I know everyone isn’t a fan of Apple, but ever since Tile was bought by Life360 and Life360 sells your location data to 1000’s of companies, maybe take that dead Tile Slim battery as a sign it’s time to also upgrade your privacy.

Hope this helps someone else.

PS. Don’t forget to properly recycle your Tile Slim. You shouldn’t throw electronics in your household garbage and batteries should be recycled. Check out the EPA for more info.
