NShi 84Wh 6-cell laptop battery for Dell XPS 15 9550 Precision 5510 4GVGH

SKU CH-9BHV-BBRV2

84Wh 6-cell lithium-polymer replacement battery for Dell XPS 15 9550 and Precision 5510 laptops

  • Battery TypeLithium Polymer
  • 84 Wh capacity extends runtime for Dell XPS 15 9550 and Precision 5510
  • 6-cell lithium-polymer design stores more energy than the 56 Wh 3-cell alternative
  • 4 V output matches original specification for stable performance
  • Replaces part numbers 4GVGH, T453X, 0T453X, 1P6KD, 04GVGH, 01P6KD, P56F, P56F001, 451-BBUX
  • CE, FCC and RoHS certified for safety and quality assurance

Compatible Dell models

This 6-cell lithium-polymer battery replaces the Dell 4GVGH pack in XPS 15 9550 and Precision 5510 mobile workstations. It matches part numbers including T453X, 1P6KD and 451-BBUX for direct fitment. The 84Wh capacity restores original runtime for these 15-inch systems. It will not fit laptops that require the 56Wh 3-cell RRCGW variant.

Capacity and voltage

Rated at 84Wh and 11.4V, the pack supplies enough energy for extended work sessions away from mains power. Six cells provide headroom for demanding workloads such as video editing or CAD on the Precision 5510. Runtime falls short only when sustained peak loads exceed the cell chemistry's discharge capability. The upgraded cell design aims to maintain consistent output through the charge cycle.

Lithium-polymer constraints

The Li-Polymer chemistry delivers high energy density in a slim profile suited to ultrabook chassis. Capacity degrades gradually with each full charge cycle, a normal characteristic of this technology. The battery carries CE, FCC and RoHS certifications for safety compliance. Users needing longer service life than a single pack provides must plan for eventual replacement.

Questions about this item

Will the 6-cell 84Wh battery fit the same chassis as the original 3-cell 56Wh unit in my XPS 15 9550?

No, the 84Wh 6-cell 4GVGH battery is physically different and will not fit systems designed for the 56Wh 3-cell RRCGW model.

How can I confirm the new 11.4V Li-Polymer pack is charging correctly after installation?

The Dell BIOS battery health screen should report the design capacity near 84Wh and show a normal charge cycle without error codes.

Does the box include the 451-BBUX screw kit or any tools needed to swap the 6-cell battery?

Only the 6-cell 84Wh battery itself is supplied; mounting screws and opening tools must be sourced separately.
