ZTHY MV07R 68Wh Battery for Dell G3 15 & G5 15

The ZTHY MV07R is a direct-replacement 68Wh 15.2V 4‑cell lithium-ion battery engineered to restore runtime for compatible Dell G3 15 and G5 15 laptops.

If your Dell G3 15 (3500, 3590, 3700, 3790) or Dell G5 15 (5500, 5505) shows decreased battery life, unexpected shutdowns, or fails to hold charge, this ZTHY MV07R replacement offers a practical solution. Built to match the original specifications and safety certifications, it provides the same nominal voltage and capacity as the factory unit so your system can run like new again. Before ordering, confirm the part number stamped on your existing battery, since some related models use a 51Wh 3‑cell variant.

How do I confirm this battery fits my Dell model?

Check the labels and part numbers on your current battery; the MV07R compatible list includes MV07R, JJRRD, 0JJRRD, 266J9, 72WGV, W5W19, P89F, MVO7R, PN1VN, and M4GWP. Also verify your laptop model—this pack replaces batteries in G3 15 models (3500, 3590, 3700, 3790) and G5 15 models (5500, 5505).

• Match the part number printed on your existing battery.
