The pack fits a wide range of Asus laptops including K43, K53, K54, X43, X53 and several Pro and P-series models shown in the compatibility list. Buyers whose laptop requires a different voltage or a cell count other than nine should look elsewhere. Units not appearing in the supplied compatibility list are not supported.

Questions about this item

Does the battery ship with any cables or tools, or is it just the 9-cell pack?

Only the 9-cell Li-ion battery is included; no cables, screws or tools are supplied.

How do I decide between the 7800mAh and 87Wh ratings when picking a replacement?

They describe the same pack — 7800mAh at 11.1V equals 87Wh — so there is no separate version to choose.

What does the 87Wh rating actually deliver in daily use on an Asus K53?

The 87Wh capacity typically provides several hours of mixed workload runtime, and the cells are rated for about 800 recharge cycles.
