⚠️ IMPORTANT BUYING NOTICE:

• BL04XL Structural Layout Blueprint: This professional-grade 7.70V Lithium-Polymer (Li-Polymer) internal replacement battery pack features a specialized ultra-thin profile measuring exactly 292.50 x 92.50 x 5.50 mm and weighing an agile 235.00 g. It drops securely flat into your laptop's designated lower internal chassis tray without generating outer casing alignment strain, frame bowing, or mechanical trackpad click stiffness.

• Model Generation & Series Verification (Crucial Rule): This high-efficiency power engine is custom-built exclusively for the fifth and sixth-generation (G5 and G6) HP EliteBook x360 1040 convertible multi-touch series. Please note that it will not fit traditional, non-convertible EliteBook 1040 G5/G6 clamshell models, nor will it work with older iterations (such as the EliteBook 1040 G1, G2, G3, or G4), which rely on entirely separate structural frame footprints, alternative connection pin alignments, and completely different voltage parameters. Before finalizing your purchase, unscrew your notebook's bottom cover panel to verify that your stock factory battery explicitly features original part numbers like BL04XL, BL04056XL, HSTNN-DB8M, or L07041-855.
