Replacement for Inspiron and Vostro laptops

This 9-cell lithium-ion battery delivers 87 Wh at 11.1 V and replaces original Dell packs such as J1KND, YXVK2 and 312-0233. It fits a wide range of Inspiron 13R, 14R, 15R and 17R models plus Vostro 3450, 3550 and 3750 machines. Buyers needing a higher-capacity pack for newer Dell ultrabooks or gaming chassis will not find a match here.

Cool running and stable voltage

The lithium-ion chemistry maintains a steady 10.8 V nominal output during typical office and media workloads. No active cooling is required and the pack adds no audible noise to the system. Users who rely on sustained high-current draw for discrete GPU loads should verify their original spec sheet first.

Direct-fit form factor

The battery uses the original 9-cell footprint and connector layout, so it seats in the existing bay without adapters or case modification. The design aligns with Dell part numbers 04YRJH, 07XFJJ and FMHC10 for a secure latch. Owners of thinner Inspiron models that accept only 4-cell or 6-cell packs cannot use this unit.

Questions about this item

How do I install this 9-cell battery in my Inspiron N5010, and which step do people get wrong?

Power off the laptop, disconnect the AC adapter, slide the release latch, remove the old pack, align the new 11.1 V 7800 mAh unit with the guide rails, press until the latch clicks, then reconnect power. The step often missed is fully seating the pack so the latch engages on both sides.

What maintenance or replacement will this 87 Wh lithium-ion pack need later?

Lithium-ion cells lose capacity over time and charge cycles; when run-time drops below useful levels the pack must be replaced. No user-serviceable parts exist inside.

What limit appears first under sustained heavy load on this 11.1 V 7800 mAh battery?

The 87 Wh energy capacity sets the runtime ceiling; under continuous high drain the pack will reach its depth-of-discharge limit before any thermal throttle activates.
