NShi J0PGR 7.6V 42Whr 4-cell laptop battery for Dell Latitude 5285 5290

4-cell replacement battery for Latitude 5285

This 7.6 V lithium-ion pack is built as a direct replacement for Dell part numbers J0PGR, X16TW, FTH6F, 0X16TW and 0FTH6F. It fits the Latitude 5285 and Latitude 5290 two-in-one tablets and traditional clamshells. The unit ships new and ready to install.

42 Whr capacity with 5526 mAh at 7.6 V

The four-cell design stores 42 Whr of energy, delivering 5526 mAh at the nominal voltage. That capacity supports typical office workloads, web browsing and video playback for a full workday on a single charge. Heavier sustained loads such as rendering or large compilations will drain the pack more quickly.

Low heat output and silent operation

As a solid-state power source the battery generates no fan noise and adds negligible heat to the chassis during normal use. Power draw follows the laptop's own consumption profile, so thermal behaviour matches the original Dell pack. The lithium-ion chemistry maintains stable voltage until the charge is nearly exhausted.
