⚠️ IMPORTANT BUYING NOTICE:

• 245RR Extended 6-Cell Layout: This premium 11.10V Lithium-Polymer (Li-Polymer) internal replacement battery pack features an extra-long, high-capacity profile measuring exactly 356.00 x 110.10 x 9.30 mm and weighing 350.00 g. It drops directly into the lower base tub assembly of your laptop without causing outer frame bulging, casing tension, or internal trackpad click stiffness.

• Storage Space Restrictions (Crucial Rule): This is the extended-capacity 91Wh maximum-spec configuration module under part number 245RR. 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 an M.2 SSD or mSATA storage stick. If your laptop configuration 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 2.5-inch hard drive bay space. If your system relies on a 2.5-inch internal drive, you will need the shorter 61Wh (T0TRM) battery alternative.

• Compatibility & Voltage Verification: Before completing your order, please unscrew your laptop's lower backplate to verify that your original factory battery displays a native operational voltage rating of 11.1V and explicitly matches part numbers like 245RR, H76MV, or 0H76MY.
