Replacement Battery for Dell Inspiron and Vostro

The 2-Power J1KND is an 11.1V 48Wh lithium-polymer pack built to replace the original Dell J1KND battery in Inspiron 13R, 14R, 15R and 17R notebooks as well as Vostro 1440, 1450, 1540, 1550, 3450, 3550, 3555 and 3750 models. It delivers 5200mAh across six cells and matches the OEM form factor for a direct fit.

Upgrading from a Depleted or Failing Pack

This battery replaces units that no longer hold charge, show rapid capacity loss or trigger BIOS warnings about battery health. The jump is worth it when the original cell chemistry has degraded past the rated 1000 cycles or when a swollen pack prevents the laptop from sitting flat. It restores full runtime without requiring a new power adapter.

Limits of the 11.1V 6-Cell Standard

The 11.1V six-cell architecture fixes the maximum energy at 48Wh, so runtime scales only with load and power-management settings. Physical dimensions of 8.35in by 2.35in by .87in mean the pack fits only the listed chassis; it cannot be used in thinner ultrabooks or models that require a different voltage or cell count. No higher-capacity version exists in this form factor.

Questions about this item

Will the 6-cell J1KND battery fit the original bay on my Dell Inspiron 15R N5010?

Yes, the 6-cell J1KND matches the OEM form factor for the Inspiron 15R N5010 and slides into the same battery bay without adapters.

What is the common installation mistake when replacing the J1KND pack?

Many users forget to slide the locking latch fully until it clicks; the battery will seem seated but will lose contact under vibration.

After roughly how many charge cycles should I expect the 48 Wh pack to need replacement?

The manufacturer rates the J1KND for more than 1000 cycles before capacity drops to a level that warrants a new pack.
