This battery suits owners of the compatible Dell Inspiron models who need a direct replacement for the original pack. It is not for users whose laptop requires a different voltage, capacity or physical connector. Buyers with unlisted models should verify their original battery part number before ordering. The one-year manufacturer warranty covers defects in materials and workmanship.

11.4V 3400 mAh lithium polymer specification

The critical specification is the 11.4V 3400 mAh lithium polymer rating, which must match the original battery exactly. A different voltage or chemistry will prevent correct charging and may damage the laptop. Confirm the original battery shows 11.4V and 3400 mAh or 42Wh before purchase. The smart chip manages charge cycles to extend usable runtime.

Questions about this item

My Dell Inspiron 15 7579 currently uses a Y3F7Y battery — will this MPL05308P-07 fit without any other parts?

Yes, the MPL05308P-07 directly replaces the Y3F7Y in the Inspiron 15 7579 and seats in the existing bay with no extra hardware.

If I keep my original 42 Wh charger, will the 11.4 V lithium-polymer pack charge at normal speed?

The built-in smart control chip negotiates with the stock 42 Wh adapter, so charging proceeds at the standard rate for an 11.4 V 3400 mAh cell.

After installing the MPL05308P-07, how can I confirm the 3400 mAh capacity is being reported correctly?

Open the Dell Power Manager or BIOS battery information page — it should show 11.4 V design voltage and a full-charge capacity near 3400 mAh.
