⚠️ IMPORTANT BUYING NOTICE:

• 1FXDH 4-Cell XL Layout Architecture: This premium 11.40V Lithium-Polymer (Li-Polymer) internal replacement battery pack features an extra-long high-density configuration measuring exactly 349.00 x 104.00 x 8.50 mm and weighing 442.00 g. It drops directly into the lower base tub assembly of your system without causing case buckling, trackpad stiffness, or uneven chassis alignment.

• Storage Space Restrictions (Crucial Rule): This is an extended-capacity 97Wh battery. Due to its maximum physical length, it spans across the entire lower bay inside your machine. It is ONLY compatible with systems that exclusively use M.2 SSD or mSATA storage sticks. If your laptop currently uses a traditional 2.5-inch SATA mechanical hard drive or a 2.5-inch SSD enclosure, this battery will not fit, as it completely takes over that physical hard drive bay space.

• Compatibility & Voltage Verification: Before completing your order, please unscrew your laptop's bottom cover to verify that your original internal battery displays a native operational voltage rating of 11.4V and explicitly matches part number 1FXDH.
