This unit fits Inspiron 3558, 3559, 3565, 3567, 5451, 5452, 5455 and 5458 when the original battery matches the product photos. Buyers with different Dell series or mismatched connectors should look elsewhere because the two variants are not interchangeable.

40Wh capacity decides runtime

The 40Wh rating determines how long the laptop runs on a single charge. Verify that your original battery shows the same voltage and cell count before ordering, as the physical layout differs between the two versions Dell produced for these chassis.
