Replacement battery for Dell 16-inch laptops

This 6-cell lithium-ion unit replaces the original Dell P0FWH pack in the Inspiron 16 Plus 7640, Inspiron 16 7640 2-in-1 and Alienware M16 R2. It delivers 11.7V and 90Wh from a 7692mAh cell stack. The black casing measures 12 by 3.4 by .5 inches and weighs .9 lb.

Voltage and capacity limits

The 11.7V nominal voltage is fixed by the laptop's charging circuit; a higher-voltage pack will not charge and a lower-voltage pack will not power the system. Capacity is capped at 90Wh, so runtime matches the original specification and cannot be extended without a chassis redesign.

90Wh capacity decides fit

The 90Wh rating determines whether this battery physically and electrically matches the Dell service manual for the listed models. Buyers who need a higher-watt-hour pack for longer unplugged time will not find it in this form factor.

Questions about this item

Which part number should I pick for my Inspiron 16 Plus 7640?

All listed part numbers — P0FWH, 0M9DG0, M9DG0, CN-0M9DG0, 01969N, 1969N, CN-01969N, HGJCY, 0HGJCY, CN-0HGJCY — refer to the same 11.7V 90Wh 6-cell battery; choose the one printed on your original pack.

What does the 90Wh rating mean for daily use on an Alienware M16 R2?

The 90Wh capacity matches the OEM specification, so you should see the same run-time per charge that the laptop delivered when it was new.

Does the 11.7V output work with the Dell charging circuit in the Inspiron 16 7640 2-in-1?

Yes — 11.7V is the factory voltage for these models, and the battery includes the protection circuitry the Dell power-management system expects.
