Compatible 75Wh replacement battery

This 11.4V lithium-ion battery replaces the original 8N0T7 pack in Dell XPS 15 9575 and Precision 5530 2-in-1 systems. It matches the factory voltage and 75Wh capacity so runtime returns to like-new levels. The black casing fits the existing bay without modification. Installers should verify the part number before fitting.

Capacity and voltage match

The single specification that decides fitment is the 75Wh capacity at 11.4V, which must equal the original battery rating. A lower capacity would shorten runtime; a different voltage would prevent the laptop from recognising the pack. This unit meets both figures exactly, so the firmware accepts it and the fuel gauge reports correctly.

Steady discharge under load

Under sustained workloads the cell chemistry delivers a stable 11.4V output until the 75Wh reserve is depleted, avoiding the voltage sag that causes sudden shutdowns on worn packs. The lithium-ion construction maintains consistent current during long compile sessions or video exports. Temperature rise stays within normal limits for the chassis design.

Questions about this item

How long will the 75 Wh capacity actually run my XPS 15 9575?

The 75 Wh rating matches the original Dell specification, so real-world runtime should be equivalent to a factory-fresh battery under the same workload.

Does the 11.4 V lithium-ion pack use the same connector and pinout as the original 0TMFYT part?

Yes, it is built to the 0TMFYT / P73F001 pinout and will seat directly into the XPS 15 9575 or Precision 5530 2-in-1 battery bay.

Will this black 8N0T7 pack fit the XPS 15-9575-D1805TS chassis without modification?

The pack shares the exact dimensions and screw-hole pattern of the Dell 0TMFYT unit, so it drops into the D1805TS and all listed 9575 variants.
