Details

An Apple Watch that once lasted a full day now dies during an evening run, or switches off at 30 percent when it gets cold. Battery wear shows up faster on a watch than on a phone, because the cell is tiny and charged every day. Sometimes the battery swells and pushes the screen up from the case, which needs attention right away.

This aftermarket internal battery is offered for Series 1 to Series 9, SE, SE 2, Ultra and Ultra 2. Each series and case size uses its own battery, so choose both in the options.

Signs the battery needs replacing

Common signs are a watch that doesn't last a day, unexpected shutdowns, slow or failed charging, and a screen lifting at one edge because the battery has swollen. On newer models, Settings > Battery > Battery Health on the watch can help confirm wear.

Replacing it is an advanced repair: the display is held with adhesive and connected by delicate flex cables. Use gentle heat and a thin blade, don't lift the display further than the cables allow, and fit new display adhesive when closing. Water resistance can't be relied on afterward.

A fresh battery makes a watch that still works well good for daily wear again.

Questions

Are batteries interchangeable between case sizes?

No. Each series and case size uses its own battery, with different dimensions and connectors. Select both.

How do I find my Apple Watch series and case size?

The case size and model number are engraved on the back. Apple's Identify your Apple Watch page lists which model numbers belong to each series.

How difficult is the replacement?

It's an advanced repair because the display is adhesive-sealed. Use heat and a thin tool, protect the display flex cables, and fit new display adhesive.

Is this a genuine Apple battery?

No. It's an aftermarket battery made to fit the Apple Watch.
