⚠️ IMPORTANT BUYING NOTICE:

• KC04XL Ultra-Thin Precision Form Factor: This professional-grade 15.40V Lithium-Polymer (Li-Polymer) internal replacement battery pack features an exceptionally slim layout profile measuring exactly 289.00 x 88.60 x 6.00 mm and weighing an ultra-lightweight 211.00 g. It drops completely flat into your laptop's lower internal chassis tray without generating outer frame bulging, casing alignment tension, or mechanical trackpad click resistance.

• Compatibility & Part Number Verification: This specific engineering footprint is custom-tailored for the HP Envy 13-ah0000 series. Please note that it will not fit other Envy 13 generations (such as the 13-ab, 13-aq, 13-ba, or 13-ad lines), which rely on completely different physical dimensions and connector positions. Before completing your purchase, please unscrew your notebook's bottom cover plate to verify that your original factory battery explicitly displays a native operational voltage of 15.4V and lists original part numbers like KC04XL.
