68Wh 4-cell Dell Latitude battery

The FOCUSTEC GJKNX is a 7.6V lithium-polymer replacement battery rated at 68Wh across four cells. It fits a wide range of Dell Latitude 5480, 5580, 5280, 5490, 5590 and Precision 3520 and 3530 models. The pack ships with screwdrivers so the swap can be done without extra tools. It is built for owners of those specific machines who need a fresh power source.

Sustained cycle life and protection

The cell chemistry is rated for up to 500 recharge cycles over the life of the battery. Integrated circuitry guards against overcharge, overdischarge, over-temperature and short-circuit events during long work sessions. Steady output at 7.6V supports consistent run-time rather than a brief peak. The black casing matches the original aesthetic.

Replaces worn original packs

This unit replaces Dell part numbers GD1JP, DY9NT, 5YHR4, 451-BBZG, FPT1C, KCM82 and MT31P when the original pack no longer holds charge. The upgrade is worth it when run-time has dropped below useful levels or the battery reports a permanent fault. It is not for laptops outside the listed Latitude and Precision series or for users needing a higher capacity than 68Wh.
