Will This Battery Work in Your Laptop?
“Spectre x360 14” is not enough to pick a battery. HP uses different batteries across generations, so match your exact model before you buy. Run this quick check first.
The 14-eu0xxx generation uses a different 4-cell, 68 Wh battery, which makes it a poor match. HP’s service guide also advises using the battery supplied with the computer, an HP replacement, or a compatible battery bought from HP. The OUWEE WS04XL is a third-party option, not an HP-approved part.
