Direct replacement for Dell laptops

This 43Wh lithium-ion battery replaces part numbers GK5KY, 04K8YH, 092NCT, 0WF28 and 451-BBKK in compatible Dell notebooks. It delivers 11.1V across three premium cells and arrives new with CE and RoHS certification. Buyers who need a higher capacity or a different voltage should verify their original part before ordering.

Fits without extra parts

The pack is designed to slot into the existing battery bay using the original connectors, so no cables, brackets or tools are required beyond what the laptop already provides. It restores full mobile operation and frees the user from staying tethered to an AC adapter. Systems that use a different physical layout or connector keying will not accept this unit.

Steady output over long sessions

Lithium-ion chemistry maintains a stable voltage curve during extended workloads such as document editing, media streaming or video calls, reducing the sudden drops seen with aged cells. The three-cell construction balances runtime and thermal behaviour for consistent daily use. It is not intended for high-drain scenarios that exceed the design limits of a 43Wh pack.

Questions about this item

How long will the 43 Wh capacity keep my Dell running under continuous load?

The 43 Wh rating indicates the total energy the 3-cell lithium-ion pack can deliver; actual runtime depends on your laptop's power draw during sustained use.

Does the 11.1 V lithium-ion pack run hot or loud when the laptop is on all day?

The battery itself has no moving parts and generates minimal heat during normal discharge; system thermals are managed by the laptop's own cooling design.

Which Dell models accept the GK5KY, 04K8YH, 092NCT, 0WF28 or 451-BBKK part numbers?

This pack is built to fit Dell notebooks that originally used any of those part numbers; match the code on your old battery to confirm compatibility.
