40Wh 14.8V Lithium-Ion Replacement

This 40Wh 14.8V lithium-ion battery replaces the M5Y1K pack in compatible Dell Inspiron 14, 15 and 17 models. It supplies 2600mAh across four cells and arrives new with a manual. Buyers restoring runtime on listed Inspiron 3000 and 5000 series laptops can use it as a direct swap. It is not for owners of Dell models outside the fit list or for systems requiring a different voltage or cell count.

Check Model Number and Voltage

Before ordering, confirm the original battery part number matches one of the listed replacements such as M5Y1K, P51F, VN3N0, GXVJ3, HD4J0 or 991XP. Verify the laptop label shows 14.8V and that the chassis fits the 10.6 x 1.5 x 0.75 inch form factor. Do not install if the part number or voltage differs, as incorrect packs can cause charging errors or physical mismatch.

Manual Included for Installation

The package includes one M5Y1K battery and a printed manual. The manual guides safe removal of the old pack and insertion of the new unit without special tools. No driver disc, calibration software or AC adapter is bundled. The manual does not replace the laptop service guide, so consult the manufacturer documentation for model-specific screw locations or cable routing.
