Questions about this item

Does the box include the battery only, or are tools and a charger also supplied?

The package contains the 6 cell lithium ion battery itself; a charger and any installation tools are not included and must be obtained separately.

Which capacity should I choose for an Asus K55 series laptop that originally used an A32-K55 battery?

This model provides 4400 mAh at 10.8 V, matching the original A32-K55 specification, so it is the correct capacity for that laptop.

What does the 48 Wh rating mean for daily runtime on my Asus X75?

The 48 Wh rating indicates the total energy the pack can deliver; actual runtime depends on the X75 power draw, screen brightness and workload, but it restores the original factory capacity.
