Questions about this item

Does the 8-cell 14.4V lithium-ion pack run hot or draw extra power during long sessions?

The 63Wh battery is built to OEM spec with a smart control chip that manages charging current and protects against overheating, so it operates at normal laptop temperatures under typical all-day loads.

You need an HP ProBook 4730s or 4740s that originally used part numbers 633734-141, 633734-151, 633734-421, 633807-001, HSTNN-I98C-7, HSTNN-IB25, PR08, QK647AA or QK647UT.

Will this 4400mAh replacement behave the same as the original battery in an older ProBook 4730s?

Yes — it matches the original 14.4V voltage, 8-cell layout and 63Wh capacity, and the built-in protection chip communicates with the laptop's power management exactly like the factory pack.
