A1579 Replacement Battery for Apple Watch Series 1 Battery 42mm.A1554, A1579, A1803, with Complete Repair Tool Kits + Back Cover Adhesive + Installation Instruction.

This battery has shown me how really bad my old one was. The kit came with everything you’ll need to install your new battery. It arrived quickly.

Installed battery worked fine for three days. Now won’t hold a charge beyond an hour. Has a weird squiggly line that say it’s charging but it’s clearly not.

Adhesive gasket did not work for me, I used B7000 glue, worked better

The main complaint I have is about the included double sided tape that supposed to hold the screen in place after replacing the battery. I cleaned the surface, and tried sealing the screen twice using included seals, but neither time it worked and screen came of minutes after wearing the watch. I even tried clamping the screen for a few hours to make the screen stick to the frame but that didn’t help.I’d recommend the seller including a good seal instead of adding a bunch of useless tools.

Installed easily but battery did not work. Put old battery back in and it works but puffy so it will not close. New battery does nothing! Very disappointed because I used it so I cannot return

Replaced the battery and its bad, won’t even charge! Also the adhesive did not stick well. May have gotten a dud box, but would not purchase again.

I received a non working battery and could not return it.
