⚠️ IMPORTANT BUYING NOTICE:

• CC03XL Structural Layout Warning (Two Forms Exist): This professional-grade 11.55V Lithium-Polymer (Li-Polymer) internal replacement battery pack features an architectural footprint measuring exactly 282.80 x 81.00 x 7.10 mm and weighing 203.00 g. HP utilized two entirely distinct frame outlines and mounting tab layouts under the shared "CC03XL" family name. This specific version is the larger 56Wh layout containing a three-tab alignment layout along with an adjusted side mounting bracket configuration. It is structurally distinct from the smaller 52Wh (Type 1) version and they are not cross-compatible. Before finalizing your order, you must unscrew your notebook's bottom shell panel to look directly at your stock battery's mounting eyelets, layout profile, and original labels to guarantee an exact alignment.

• Model Generation & Series Verification: This specific power module is carefully engineered for seventh and eighth-generation (G7 and G8) large-screen business platforms, including the HP EliteBook 850 G7, 850 G8, 855 G7, and 855 G8, along with corresponding ZBook Firefly 15 G7 and G8 workstations. It will not fit smaller configurations (such as EliteBook 830/840 series) or older generations (such as EliteBook 850 G5 or G6), which utilize an entirely separate battery framework. Check that your internal labels match identifiers such as CC03XL, CC03056XL, CC03056XL-PL, HSTNN-DB9O, or L77991-005.
