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.
