Replacement 6-Cell Lithium-Ion Battery

This new 10.8V 4400mAh battery replaces the original HP ProBook power pack for models such as the 4330s, 4440s and 4540s. It matches the OEM 633733 and 633805 part numbers and restores mobile runtime to factory levels.

Direct Fit for ProBook Chassis

The pack slides into the existing battery bay without adapters or cable changes, freeing the user from a tethered AC adapter. Built-in smart-chip protection guards against short circuit, overheat and overload during every charge cycle.

Steady Output Through Full Discharge

The 48Wh lithium-ion cells deliver consistent voltage from start to finish, avoiding the sharp drop-off seen in aged packs. A one-year warranty backs the rated capacity for daily workloads away from mains power.

Questions about this item

How long will the 4400 mAh capacity last before the 6-cell pack needs recharging under heavy load?

The 48 Wh rating gives roughly 2 to 3 hours of continuous high-drain use before a recharge is required.

Does the built-in smart control chip keep the 10.8 V pack cool and quiet during all-day operation?

The chip manages overheat protection and power consumption, so the battery runs silently and stays within safe temperature limits.

Which original HP part numbers must match for this replacement to work in my ProBook?

Compatible part numbers include 633733-151, 633733-1A1, 633733-241, 633733-251, 633733-321 and 633805-001.
