56Wh 33YDH Replacement Battery for Inspiron 17

This 56Wh lithium-ion battery replaces the original power source in Dell Inspiron 17 7000 models including 7577, 7773, 7778, 7786, and 7779 2-in-1 units. It is built for owners who need a direct swap to restore full mobile runtime without modification.

7.6V Lithium-Ion Chemistry and Four-Cell Layout

The pack operates at 7.6V using a four-cell lithium-ion design rated at 62Wh high-performance capacity. Runtime scales with the host laptop's power draw, so heavy workloads will deplete the charge faster than light office tasks.

Replaces Worn or Failed Original Packs

This unit fits only the specific Inspiron 17 7000 variants listed; three different batteries exist for these chassis and they are not interchangeable. Buyers who cannot match their original battery to the product photos should not purchase this model.

Questions about this item

Does the 56Wh or 62Wh capacity match my original battery?

The listing shows 56Wh in the title and 62Wh in the specifications. Check the Wh rating printed on your original 33YDH battery to confirm which capacity you need.

How long will the 62Wh capacity actually run my Inspiron 17 7000?

Runtime depends on your specific model (7577, 7773, 7778, 7779, 7786) and workload, but a 62Wh 4-cell lithium-ion pack typically provides several hours of mixed use on these 17-inch systems.

Will the 7.6V voltage work with my Dell laptop's charging circuit?

Yes, the 7.6V output is designed to fit Dell laptops requiring that voltage, and the battery is listed as 100% compatible with the specified Inspiron 17 7000 series models.
