40Wh 3-cell lithium polymer battery

This 40Wh lithium polymer battery operates at 11.25V and contains three cells rated at 3550mAh. It is a brand new replacement part for select Dell Latitude, Vostro and Inspiron laptops including the 3120, 3410, 3510, 5300, 5400 and 7300 series.

Direct swap with built-in circuit protection

The battery matches the original JK6Y6, H5CKD and 7T8CD form factors so it fits the existing bay without modification. Built-in circuit protection guards against overcharge and short circuits, and the cell chemistry is rated for more than 500 recharge cycles.

Check model suffix and colour before ordering

Several Inspiron 2-in-1 models exist in both Silver and Black chassis; this pack fits only the Silver variants of the 7300, 7306, 7500 and 7506 series. Verify the exact model number on the base of your laptop against the supported list to avoid a mismatch.

Questions about this item

How can I verify the JK6Y6 battery is working after installation?

The laptop should power on using battery power alone and the operating system or BIOS should recognise the new pack and show it charging normally.

What comes with the NShi JK6Y6 and what must I buy separately?

The package contains the 3-cell 40Wh lithium polymer battery only; no tools, screws or additional cables are included.

Which JK6Y6 version should I choose for a Dell Inspiron 7300 2-in-1 Silver?

This battery fits the Inspiron 7300 2-in-1 Silver series; it does not fit the black-chassis versions of the 7300 2-in-1.
