Despite the other radical redesigns, the Surface Laptop 3's battery looks relatively unchanged—same pinned-under-the-board connector, same miserable removal process.

A whole lotta solvent, prying, and patience later, we have lift-off. No stretch-release adhesive here—this tape is tough and really wants to stick around.

Spec-wise, the battery comes in at 45.8 Wh—in both the 15" and 13.5" models. In fact, it's the exact same battery.

This is slightly more than the original Surface Laptop (45.2 Wh) and the Surface Pro 6 (45 Wh). For those of you who measure everything in Apples, it's less than in the 15" MacBook Pro (83.6 Wh).
