• Model Generation & Series Verification (Crucial Rule): This high-efficiency power engine is custom-engineered exclusively for late 2016–2017 premium HP Spectre x360 13-W and 13-AC (13-w000 through 13-w099 & 13-ac000 through 13-ac099) convertible 2-in-1 models. Please note that it will not fit other Spectre 13 generations (such as the older 13-4000 series, or later versions like the 13-ae, 13-ap, or 13-aw lines). Those alternative models utilize completely distinct physical casings, incompatible connection ribbon locations, and varied voltage lines. Before completing your purchase, safely open your laptop's lower enclosure panel and verify that your old factory battery displays the product model identifier SH03XL or HP spare parts number 859356-855.
