Replacement for HP ProBook series
This 6-cell lithium-ion battery replaces original HP part numbers including 633733-321 and HSTNN-DB2R. It fits ProBook models such as the 4330s, 4430s, 4446s, 4530s and 4545s. The unit ships new and carries a one-year warranty from Dr. Battery, a brand established in 2006.
Thermals and power in daily use
The pack operates at 10.8 V and stores 4400 mAh for a total of 48 Wh. A built-in smart control chip manages charging to reduce power consumption and extend discharge time. Protection circuits guard against short circuit, overheat and overload during normal operation.
Behaviour under sustained load
The same protection circuits remain active during prolonged discharge, limiting temperature rise and preventing overload. Cell balancing from the control chip helps maintain consistent output over long sessions. The 48 Wh capacity supports extended mobile work without requiring a recharge.

Questions about this item
How do I install the MPL08251P-14 battery in my HP ProBook 4530s, and what step is often missed?
Slide the pack into the battery bay until the latch clicks; the step often missed is verifying the original part number 633733-321 or 633805-001 on the old battery before fitting the new one.
What maintenance or replacement will the 6-cell 4400 mAh pack need later?
The lithium-ion cells degrade with each charge cycle; plan to replace the pack when run-time drops below your needs, typically after one to two years of daily use.
What limit appears first during sustained use of the 10.8 V 48 Wh battery?
The 4400 mAh capacity sets the runtime ceiling; under continuous load the pack will reach its discharge limit before thermal protection activates.
