Replacement Battery for Dell XPS 13 7390 2-in-1

This GreenTech 52TWH battery replaces the original Dell unit in the XPS 13 7390 2-in-1 and XPS 7390 2-in-1 models. It is a brand-new, four-cell lithium-ion pack supplied in black. The part matches OEM numbers 52TWH, NN6M8, XX3T7 and their CN-prefixed variants.

7.6 V 51 Whr Capacity

The single specification that confirms fit is the 7.6 V voltage paired with a 51 Whr energy rating and 6710 mAh charge capacity. These figures must match the original battery label exactly; a different voltage or watt-hour value indicates an incompatible pack.

Four-Cell Lithium-Ion Pack for Internal Installation

The battery slots into the internal chassis bay of the supported XPS 13 7390 2-in-1 models, requiring no external cabling or adapter changes. It restores mobile operation for users whose original pack no longer holds charge, while freeing the AC adapter for desk use only. Buyers needing a higher-capacity extended-life battery or a different form factor will not be served by this direct-replacement design.

Questions about this item

What runtime does the 51Whr capacity typically deliver in a Dell XPS 13 7390 2-in-1?

The 51Whr rating matches the original specification, so expect comparable battery life to the factory pack under the same workload.

How does the 7.6V output interact with the laptop's charging circuit?

The 7.6V nominal voltage is identical to the OEM design, allowing the existing charging controller to manage charge cycles without modification.

Will the 4-cell pack fit the internal bay of the XPS 13 7390 2-in-1 without modification?

Yes, the 4-cell form factor is built to the same dimensions as the original 52TWH battery, so it seats directly in the existing compartment.
