⚠️ IMPORTANT BUYING NOTICE:

• RE03XL Internal Slim-Chassis Layout Blueprint: This professional-grade 11.55V Lithium-Polymer (Li-Polymer) internal replacement battery pack features a specialized ultra-thin structural layout measuring exactly 184.70 x 101.70 x 5.80 mm and weighing an agile 243.50 g. It seats securely flat into your laptop's designated internal chassis tray alignment guides without generating structural pressure against the lower baseplate panel, preventing palm rest warps or mechanical trackpad click stiffness.

• Model Generation & Series Verification (Crucial Rule): This high-efficiency power engine is custom-built exclusively for the sixth-generation HP ProBook 430 G6, ProBook 440 G6, and ProBook 450 G6 business notebook series. Please note that it will not fit older ProBook platforms (such as the ProBook G1, G2, G3, G4, or G5 lines), nor will it fit later redesigned systems (such as the G7, G8, or G9 lines). Those alternative iterations utilize completely different internal physical dimensions, non-matching screw alignment tabs, alternative terminal connection layouts, and alternative voltage matrices. Before completing your checkout order, unscrew your notebook's lower base cover plate to physically verify that your stock factory battery explicitly features tracking part numbers like RE03XL, RE03, L32407-2B1, or HSTNN-DB9A.
