Compatibility checklist

Fits Dell Inspiron 13, 14, 15 and 17 models including 3000, 5000 and 7000 series such as 3493, 3780, 3781, 3782, 3785, 3790, 3793, 5378, 5379, 5567, 5570, 5579, 5765, 5767, 5770, 7368, 7378, 7560, 7573 and 7579. Also fits Latitude 3189, 3340, 3390, 3400, 3480, 3490, 3500, 3580 and 3590. Not for laptops that require the 56 Wh 33YDH or the 42 Wh YYRD6 packs; buyers needing those capacities should look elsewhere.

Capacity verification step

The only specification that decides fitment is the original battery’s rated capacity of 42 Wh. If the existing pack is labelled 56 Wh (33YDH) or carries the YYRD6 part number, this battery will not work. Check the label on the old battery before ordering.

Questions about this item

How much heat does the 42Wh 11.4V 3-Cell battery generate during all-day use?

The 42Wh 3-Cell lithium-ion pack produces minimal heat under normal load; keep vents clear and avoid blocking the laptop's cooling system for best thermal performance.

What must I already own to install the WDX0R 42Wh battery?

You need a compatible Dell laptop — such as Inspiron 13 7378, 15 5570, 15 7579, or Latitude 3340, 3400, 3480, 3490, 3500, 3580, 3590 — that originally uses the 42Wh WDX0R pack, plus a small Phillips screwdriver.

Will the WDX0R 42Wh battery work alongside my existing 56Wh 33YDH pack in a Latitude 3400?

No — Latitude 3400 accepts either the 42Wh WDX0R or the 56Wh 33YDH, not both at once; verify the original battery label matches WDX0R before purchasing.
