11.1V 5200mAh 6-cell replacement battery

This new lithium-ion battery delivers 11.1 volts and 5200mAh across six cells. It fits Dell Inspiron 13R 14R 15R 17R models and matches part numbers such as J1KND and 4T7JN. Owners of compatible N-series and M-series notebooks can restore original runtime without modification.

Direct-fit design with certified safety

The pack uses the original connector layout so it seats in the existing battery bay with no adapters. UL CE FCC and RoHS certifications cover the unit, and built-in protection guards against short circuit and overcharge during daily charge cycles.

Capacity fixed by cell count and chemistry

Six lithium-ion cells set the energy ceiling at 5200mAh; runtime scales with workload and screen brightness rather than any firmware tweak. Users needing longer unplugged time would require a higher-capacity pack that the chassis does not accommodate.

Questions about this item

Does the 11.1 V lithium-ion chemistry limit the charge capacity to 5200 mAh?

The battery is rated at 11.1 V and 5200 mAh using six lithium-ion cells; that voltage and capacity combination is the specified limit for this pack.

What physical mounting does the six-cell pack use on an Inspiron 15R or 17R chassis?

The pack follows the standard Dell slide-in form factor for the listed Inspiron 13R, 14R, 15R and 17R models and locks with the existing latch.

How is the battery installed and which step is often missed?

Power off the laptop, disconnect the AC adapter, slide the pack into the bay until the latch clicks, then power on and let the BIOS recognise the new capacity.
