42WH replacement battery

This 42WH lithium-ion pack operates at 11.4V and uses four cells to replace the original power source in compatible Dell Inspiron laptops. It fits 13, 14, 15 and 17 inch models across the 5000 and 7000 series including the 5368, 5378, 5567, 5578, 7570 and 7579.

Sustained discharge behaviour

The lithium-ion chemistry delivers a steady voltage curve through typical workloads rather than a sharp drop under load. CE and FCC certification confirms the pack meets safety standards for continuous operation in daily use.

Capacity and voltage limits

At 42WH and 11.4V the pack defines the practical energy ceiling for the supported Inspiron 5000 and 7000 chassis. Systems requiring a higher watt-hour rating or a different voltage will not be compatible with this unit.

Questions about this item

Does the 11.4 V 42 Wh pack run hot during long sessions?

The lithium-ion 4-cell design operates at standard laptop temperatures; no active cooling is needed.

My Inspiron 15 7570 uses a proprietary Dell connector — does this battery include it?

Yes, it is built as a direct replacement for the Dell 42 Wh unit used in the 7570 and other listed models.

Will this 42 Wh unit fit my older Inspiron 13 5368 without BIOS issues?

It matches the original 11.4 V specification for the 5368, so the system recognises it normally.
