Replacement battery for Dell Inspiron 14R 15R 17R

The KingSener N3X1D is a 6-cell lithium-ion pack rated at 11.1 V and 6000 mAh. It replaces Dell part numbers N3X1D, M5Y0X, T54FJ and 71R31. Korean-made cells are used for consistent discharge performance. The pack ships in black and carries a two-year manufacturer warranty.

Fits 14 15 17 inch Inspiron R and SE series

This battery fits the Inspiron 14R, 15R and 17R families including SE variants such as the 4420, 4520, 4720, 5420, 5425, 5520, 5525, 5720, 7420, 7520 and 7720 models. It also covers Latitude E5420, E5430, E5520, E5530, E6420, E6430, E6440, E6520 and E6530. Buyers with non-listed Dell chassis or other brands should verify the part number before ordering.

Voltage and capacity must match the original

The decisive specification is the 11.1 V nominal voltage combined with 6000 mAh capacity. A pack with a different voltage will not charge or power the laptop correctly. Capacity determines run time, so the 6000 mAh rating should equal or exceed the original battery’s rating for equivalent mobility.

Questions about this item

Will the N3X1D 6-cell pack fit the battery bay on my Dell Inspiron 14R-5420 without modification?

Yes, the N3X1D is built to the original Dell 6-cell form factor for the Inspiron 14R, 15R and 17R families, so it seats directly in the existing bay with no adapter or trimming required.

What is the correct order to install the N3X1D and avoid the common latch-miss error?

Power off the laptop, disconnect the AC adapter, slide the pack in until the guide rails engage, then press firmly near the centre until both side latches click audibly — skipping the audible click is the step most users miss.

How often should I recalibrate the fuel gauge on the 6000 mAh N3X1D to keep the reported capacity accurate?

Run a full charge to 100%, then a complete discharge to automatic shutdown, followed by an uninterrupted recharge every 30 to 60 days; this resets the smart-circuit gauge without stressing the Korea-made Li-ion cells.
