What this battery is and who it fits

The LXHY M5Y1K is a 40Wh 14.8V lithium-ion replacement battery built for a wide range of Dell Inspiron 14, 15 and 17 models across the 3000 and 5000 series, plus selected Vostro and Latitude units. It matches part numbers including GXVJ3, WKRJ2 and HD4J0.

Who should buy it and who should not

Owners of the listed Inspiron, Vostro or Latitude notebooks needing a direct 2600mAh replacement will find this unit fits the original bay. Buyers with other Dell lines or non-Dell laptops must look elsewhere because the connector and form factor are specific to the models named above.

How it fits into a repair

The battery slots into the existing compartment without adapters and uses the stock charging circuit. It restores mobile operation for machines that currently run only on mains power and frees the user from hunting for a compatible OEM pack.

Questions about this item

Does this 14.8V 2600mAh M5Y1K battery replace the original pack in a Dell Inspiron 15 5558?

Yes — the M5Y1K is listed as compatible with the Inspiron 15 5558 among many other 5000-series models.

Will the battery fit the same bay and connector as the factory GXVJ3 unit in an Inspiron 17 5756?

The part-number list includes GXVJ3, so the M5Y1K uses the identical bay and connector for the Inspiron 17 5756.

After installing the M5Y1K, how can I confirm the laptop recognises the 40Wh capacity correctly?

In Windows, open the battery report or BIOS; the design capacity should read 40Wh and the voltage 14.8V.
