Product identity

This FOCUSTEC lithium-ion battery replaces the original power pack in Dell Inspiron 13, 14, 15 and 17 models across the 5000 and 7000 series. It is a new, 4-cell unit built for owners who need a direct swap without adapter changes.

Deciding specification

The battery delivers 42WH at 11.4V, matching the factory rating listed for compatible Inspiron 5368, 5378, 5567, 5578, 7570 and 5770 chassis. A different watt-hour or voltage value means the part will not fit or charge correctly.

Capacity and limits

The 42WH capacity restores typical mobile run-time for web browsing and document work on supported 13, 14, 15 and 17 inch systems. It will not extend usage beyond the original design envelope, and it cannot power models outside the listed Inspiron 5000 and 7000 families.

Does the 11.4 V lithium-ion pack work with the Dell 42 Wh connector used in the Inspiron 15 7000 series?

Yes, the 11.4 V lithium-ion design matches the original Dell 42 Wh specification and fits the connector used across the Inspiron 15 7000 series models listed.

Will this 4-cell battery physically fit the chassis of a Dell Inspiron 17 5770?
