Beisite 2F8K3 86Wh replacement battery

This new lithium-ion battery delivers 14.8 volts and 86 watt-hours of capacity. It is built for Alienware 17 and 18 series laptops including R1, R2 and R5 revisions. The black pack replaces part numbers such as 4ICR19/65-2 and 451-BBCB. A 12-month warranty covers the unit.

Suits owners of listed Alienware models needing

Buyers with laptops outside the Alienware 17 and 18 families listed in the compatibility data should look elsewhere. Machines requiring a different voltage or physical layout will not accept this pack. The battery is not a universal fit for other brands or newer Alienware chassis.

14.8V 86Wh lithium-ion specification

The single figure that decides fit is the 14.8 volt 86 watt-hour rating matched to the 4ICR19/65-2 form factor. If the original battery shows a different voltage or capacity this unit will not work. Verify the part number on the old cell before ordering.

Questions about this item

Does the 14.8 V 86 Wh battery fit the Alienware 17 R5 and M18X R3 chassis without modification?

Yes, it replaces part numbers 02F8K3, 2F8K3, 0G33TT, 0J33TT, 0KJ2PX, 4ICR19/65-2, 451-BBCB, G33TT and KJ2PX, which are the original batteries for those models.

Which screw or latch do I release first when swapping the 4ICR19/65-2 pack in an Alienware 17?

Remove the bottom cover screws, then disconnect the battery cable from the motherboard before lifting the old pack out; skipping the cable disconnect risks damaging the connector.

When should I replace the 86 Wh lithium-ion unit in my Alienware 18?

Replace it when run time falls well short of a full charge or the battery no longer holds 14.8 V under load; the supplier covers defects for 12 months.
