Replacement battery for HP ProBook models

This new lithium-ion battery replaces original HP packs such as 633805-001 and 633809-001. It fits a wide range of ProBook 4330, 4430, 4440, 4530 and 6460 series laptops. The six-cell design restores mobile operation for ageing or failed factory units.

4400 mAh capacity at 10.8 volts

The pack delivers 48 Wh from six grade-A lithium-ion cells rated at 4400 mAh and 10.8 V. That capacity is the single figure that determines whether the battery will meet the runtime you expect from a standard ProBook cell.

Low heat and stable output in daily use

Built-in protection circuits guard against short circuit, overheat and overload during normal charging and discharging. The cells are rated for up to 500 charge cycles with minimal thermal rise under typical office workloads.

Questions about this item

How long will the 48Wh rating actually run my laptop?

The 48Wh capacity translates to roughly three to five hours of typical office use, depending on screen brightness and workload.

Does the 10.8V output match the original HP ProBook 4540S battery voltage?

Yes, 10.8V is the standard nominal voltage for the HSTNN-DB2R and HSTNN-IB2R packs used in those models.

Will the six-cell pack fit the HP ProBook 4540S battery bay without modification?

The pack is built to the 633805-001 form factor, so it slides into the same bay as the original six-cell battery.
