Replacement battery for Dell Inspiron 13R 14R 15R

This 11.1V lithium-ion pack replaces the original Dell J1KND unit across the Inspiron 13R 14R 15R 17R families. It fits models such as N3010 N3110 N4010 N4110 N5010 N5110 N7010 and N7110. Buyers restoring an older notebook to daily use will find a direct mechanical and electrical match.

Upgrade from a worn or failed original pack

When the factory cell no longer holds charge or triggers a service alert, this 48Wh replacement restores mobile operation. The jump is worth it if the laptop otherwise meets your needs and the original battery is depleted, swollen or unrecognised by the BIOS. It is not for users who need a higher-capacity design than the original 48Wh specification.

48Wh capacity with 500-cycle rating

The 6-cell 5200mAh pack delivers 48Wh, matching the OEM energy rating for typical office and web workloads. CE and FCC certification confirms baseline safety compliance. Runtime will fall short for sustained heavy loads or users who require all-day operation without mains access.

Questions about this item

Will the 6-cell 11.1V pack fit my Inspiron 15R N5010 without a chassis mod?

Yes — the battery is built to the original Dell form factor for the entire 13R 14R 15R 17R series, so it slides into the standard bay on the N5010 with no cutting or adapters.

What is the common mistake when fitting the J1KND replacement into an Inspiron 14R N4010?

People forget to release the locking latch before pulling the old pack; the new battery clicks home only when the latch snaps fully into its recess.

After roughly how many cycles should I plan to replace this 48Wh Li-ion unit?

The manufacturer rates the cells for up to 500 recharge cycles; once runtime drops noticeably below that threshold, swap in a fresh pack.
