Dell 84Wh 4-Cell Replacement Battery

This 84Wh lithium-ion battery replaces Dell part numbers 04F5YV 4F5YV Wj5R2 Wj5R2-02 K1G3K G9G1H 4F5YV. It supplies 11.4V through four premium cells. The unit is built for owners of compatible Dell notebooks who need a direct swap for a worn original.

Practical limits of lithium-ion chemistry

Capacity fades with each charge cycle and high temperatures accelerate wear. The 84Wh rating reflects design capacity when new; actual runtime depends on the laptop's power draw and battery health. Buyers who need more storage for power or a higher voltage than 11.4V cannot use this pack.

Upgrading from a depleted original

A failing battery that no longer holds charge or triggers shutdown under load is the clear signal to replace. The jump is worth it when the old pack delivers a fraction of its rated runtime. This unit restores the factory 84Wh specification; it does not increase capacity beyond the original design.

Questions about this item

How do I know this 84Wh 4-cell 11.4V battery fits my Dell instead of the two other variants?

Match the part number on your original battery to the list — 04F5YV, 4F5YV, Wj5R2, Wj5R2-02, K1G3K or G9G1H — and compare the physical layout with the product photos before ordering.

What runtime can I expect from the 84Wh rating once the battery is installed?

The 84 watt-hour capacity stores more energy than lower-Wh packs, so it extends usable time between charges for typical workloads such as document editing or video streaming.

Does the 11.4V lithium-ion chemistry require a special charger or firmware?

No — the pack is designed as a direct replacement that works with the laptop's existing charging circuit and battery-management firmware.
