Replacement Battery for HP ProBook Series

This new 6-cell lithium-ion battery replaces original HP part numbers including 633733-151, 633733-241 and 633733-251. It fits ProBook 4330s, 4430s, 4530s and related models listed in the compatibility data. Buyers who need a different voltage or form factor cannot use this unit.

10.8 V 4400 mAh 48 Wh Specification

The electrical rating of 10.8 volts and 4400 milliampere-hours (48 watt-hours) is the single figure that decides fit. Your original battery must show the same voltage and a comparable capacity; a mismatch means the laptop will not recognise or charge the pack correctly.

Built-in Protection Chip and One-Year Warranty

The integrated smart control chip manages charging current, prevents short circuits, overheating and overload, and extends discharge time. Dr. Battery backs the pack with a one-year warranty, so a verified defect within that period qualifies for a replacement.

Questions about this item

How long will the 4400mAh capacity last in a ProBook 4330s under normal use?

The 48Wh rating gives several hours of typical office work; actual runtime depends on screen brightness, CPU load and battery age.

What voltage does the 10.8V pack deliver to the laptop's charging circuit?

It supplies a steady 10.8V nominal output, matching the original HP specification for the listed ProBook models.

Will the 6-cell black casing fit the battery bay on a ProBook 4540s without gaps?

Yes, the pack is moulded to the exact footprint of the original 633733 series batteries for those chassis.
