Questions about this item

How long will the 4400 mAh capacity last under continuous load before the battery reaches its limit?

The 6-cell lithium-ion pack stores 48 Wh at 10.8 V, giving roughly 4.4 Ah of usable charge before the built-in protection circuit stops discharge.

Does the pack run hot or make noise when the laptop is used all day?

The battery has no moving parts and produces no audible noise; heat output depends on the laptop's own thermal design rather than the cell chemistry.

Which original Asus battery part numbers must already be in the laptop for this replacement to fit?

It replaces Asus part numbers A31-U53, A32-U53, A41-U53 and A42-U53 across the listed U33, U42, U43, U52 and U53 series models.
