Compatible Laptop Battery
This 68 Wh lithium-ion replacement fits Dell Latitude 5280 5288 5290 5480 5488 5490 5491 5495 5580 5590 5591 and Precision 3520 3530 models. It matches part numbers GJKNX GD1JP DY9NT 5YHR4 451-BBZG FPT1C KCM82 MT31P and operates at 7.6 volts with four cells. The pack ships with two screwdrivers and an instruction sheet for straightforward installation.
Upgrade From Worn Original
A fresh cell restores full runtime when the factory battery no longer holds charge or reports reduced capacity after hundreds of cycles. The swap is worth it once the original drops below roughly half its initial run time or triggers a service alert in the BIOS. Systems that still meet daily workloads with the aged pack do not need an immediate change.
Capacity And Runtime Headroom
At 68 Wh the battery delivers several hours of typical office use on a single charge depending on screen brightness and load. Heavy workloads such as sustained rendering or virtualisation will drain it faster and may require mid-day recharging. The 500-cycle rating means capacity will gradually decline after extended daily cycling.

Questions about this item
Does the 68 Wh battery use the same screw positions as the original Dell GJKNX pack?

Which step do installers most often skip when fitting the 4-cell pack?
Many forget to disconnect the internal CMOS battery cable before removing the old pack, which can cause a short.
After roughly 500 charge cycles what should I plan for?
Expect the 7.6 V pack to hold noticeably less charge; a fresh GJKNX unit restores full runtime.
