Who should buy this and who should not

Owners of the listed Dell XPS 13 7390 2-in-1 notebooks needing a direct replacement will find the correct voltage, capacity and connector. Buyers with other Dell models, other XPS 13 generations or non-2-in-1 variants cannot use this battery. Shoppers who require a higher capacity than 51Wh or a different cell count should look elsewhere. The pack is intended for user installation with the supplied tools.

Deciding specification: 51Wh capacity at 7.6V

The battery delivers 51Wh (6375mAh) at 7.6V across four lithium-ion cells. This exact voltage and capacity must match the original Dell specification for the notebook to charge and report capacity correctly. A different voltage or capacity will cause charging errors or reduced runtime. Verify the original battery label shows 7.6V and 51Wh before ordering.

Questions about this item

Will the 7.6 V 51 Wh 52TWH battery fit and charge correctly in my Dell XPS 13 7390 2-in-1 that originally used the MM6M8 pack?

Yes, the 52TWH is a direct replacement for part numbers MM6M8, 0MM6M8, XX3T7 and 0XX3T7 and matches the original 7.6 V 51 Wh specification for the XPS 13 7390 2-in-1 series.

How can I verify the new 4-cell Li-ion battery is functioning properly after installation?

The battery should report 7.6 V and approximately 6375 mAh in the system BIOS or Dell Power Manager, and the laptop should run on battery power without shutting down unexpectedly.

Does the package include the 52TWH battery, installation tools and instructions, or must I buy any of those separately?

The box contains one 52TWH battery, one set of matching installation tools and the printed instructions; no additional parts are required for the swap.
