Replacement Battery for Dell Latitude and Precision

This 68Wh lithium-ion battery replaces the GJKNX part used in Dell Latitude 5480 5490 5580 5590 5495 5491 5591 5280 5290 5488 5288 E5480 E5580 E5490 E5590 and Precision 3520 3530 models. It matches the original 7.6V specification and four-cell layout. The pack is brand new and rated for 300 to 500 charge cycles.

Upgrade from Worn or Lower-Capacity Packs

If the original battery no longer holds a useful charge or if the laptop shipped with a smaller pack this unit restores full runtime. The jump is worth it when the existing cell shows reduced capacity swelling or fails to charge. It does not fit models that use the VG93N 93FTF or 3DDDG part numbers.

Capacity and Runtime Headroom

At 68Wh the battery delivers a full workday of typical office use on most supported Latitude and Precision chassis. Heavy workloads such as sustained compilation or video export will drain it faster. The four Grade A cells provide stable voltage until the pack reaches end of life after the rated cycle count.

Questions about this item

Will the 9.17 x 3.78 x 0.28 inch GJKNX battery fit inside my Dell Latitude 5480 chassis?

The pack measures 9.17 by 3.78 by 0.28 inch and is listed for the Latitude 5480, so it matches the original bay dimensions.

What is the correct way to install the 7.6 V 68 Wh pack, and what step do people often miss?

Power off, unplug the AC adapter, remove the bottom case, disconnect the old battery cable first, then connect the new GJKNX cable before refitting the case screws.

After how many cycles should I expect to replace the 4-cell Li-ion unit?

The cells are rated for roughly 300 to 500 full charge cycles before capacity drops noticeably.
