Questions about this item

How long will the 4400 mAh capacity last before the battery needs recharging under continuous load?

The 6-cell lithium-ion pack stores 48 Wh at 10.8 V; run-time varies with the laptop's power draw, so a ProBook 4540s under full load will deplete it faster than the same model idling.

Does the pack run hot or draw extra power during all-day use?

The built-in smart control chip manages charging current and provides overheat, short-circuit and overload protection to keep temperature and power consumption within safe limits.

Which HP ProBook models must I already own for this battery to fit and work?

It replaces original part numbers such as 633733-151, 633733-241 and 633805 series and fits ProBook 4330s, 4331s, 4430s, 4431s, 4435s, 4436s, 4440s, 4441s, 4446s, 4530s, 4535s, 4540s and 4545s.
