Questions about this item

How long will the 4400 mAh 6-cell lithium-ion battery last before runtime drops noticeably?

The pack is rated at 4400 mAh and 48 Wh; capacity fade typically appears after several hundred full cycles, so expect gradual reduction over 1–2 years of daily charging.

Does the battery get hot or make noise when the laptop runs all day?

It has no moving parts and produces no sound; the built-in smart chip manages charging to limit heat, but the cells will warm under sustained load like any lithium-ion pack.

What must I already own for this battery to work in my laptop?

You need an Acer Aspire model listed in the compatibility list — such as 5745G, 5820T or 7739 — and the original battery must match the 10.8 V, 6-cell form factor.
