Replacement battery for Dell G3 and G5

The NShi MV07R is a 68Wh 15.2V lithium-ion pack built to replace the original Dell MV07R, JJRRD, 72WGV, W5W19, PN1VN and M4GWP batteries. It fits Dell G3 15 3500, 3590, 3700 and 3790 models as well as Dell G5 15 5500 and 5505 series notebooks. The four-cell design targets owners of those specific laptops who need a fresh power source.

Capacity limit and model split

This pack delivers 68Wh at 15.2V using four cells; a different 51Wh three-cell variant carrying part number 266J9 exists for the same laptop families. Buyers must verify the original battery label before ordering because the two versions are not interchangeable. The chemistry is rated for up to 500 recharge cycles over its service life.

Safety certifications and daily handling

CE and UL certifications confirm compliance with electrical safety and environmental standards. Integrated protection guards against overcurrent and overheating during charge and discharge. A low-power IC design reduces standby drain, and the manufacturer recommends an initial conditioning routine of cycling between 5% and 95% three to four times. Physical disassembly, crushing or puncture is prohibited.
