Replacement battery for Dell G3 G5 Inspiron

This new NShi 266J9 lithium-polymer battery delivers 11.4 V, 51 Wh and 4 255 mAh across three cells. It replaces Dell part numbers 266J9, C9VNH, 0PN1VN, 0M4GWP, MV07R and 0415CG. The pack is coloured black and carries UL, CE, FCC and RoHS certifications.

Fits listed Dell G3 G5 Inspiron P89F models

Compatible with Dell G3 15 3500, 3590, 3790, G5 15 5500, 5505 SE, Inspiron 5490 and the P89F series. Buyers whose original battery is the 68 Wh four-cell MV07R variant will need that larger pack instead. This unit only suits the 51 Wh three-cell configuration.

51 Wh three-cell capacity decides fit

The single specification that determines compatibility is the 51 Wh three-cell rating. Dell G3 3500, 3590, G5 5500 and 5505 accept two different batteries; the 68 Wh four-cell alternative will not interchange with this 266J9 pack. Confirm the original label before ordering.

Questions about this item

Does the 266J9 battery match the 3-cell layout of my Dell G3 3500?

Yes, this 266J9 unit is a 3-cell lithium polymer pack rated at 11.4 V and 51 Wh, matching the original 3-cell form factor for the G3 3500 series.

What is the common installation mistake with the 266J9?

Buyers often confuse the 266J9 3-cell pack with the MV07R 4-cell 68 Wh alternative; verify the part number on your old battery before fitting.

How long does the 266J9 typically last before replacement?

The manufacturer rates the 266J9 for a 12-month warranty period; after that, capacity may drop below useful levels and a new pack will be needed.
