Questions about this item

Does the NShi 2F8K3 battery ship with any cables, screws or tools, or must I buy them separately?

The replacement battery is supplied as a standalone 8-cell lithium-ion pack; no cables, screws or installation tools are included, so reuse the hardware from your Alienware 17 R1 or 18 R1.

The listing shows several OEM part numbers — 2F8K3, G6M0W, 0G6M0W, KJ2PX, 0KJ2PX — which one should I match to my laptop?

All five part numbers refer to the same 14.8V 86Whr 5811mAh 8-cell design; if your Alienware 17 R1 or 18 R1 originally used any of those codes, this battery is the correct match.

What does the 86Whr rating actually deliver in daily use on an Alienware 17 R1 or 18 R1?

The 86Whr capacity provides the same energy budget as the original 8-cell pack, giving comparable run-time for the 17-inch or 18-inch chassis under identical workloads.
