What this battery replaces

The Dr. Battery MPL08251P-T01 is a six-cell lithium-ion unit rated at 10.8V and 4400mAh, delivering 48Wh. It is built as a direct replacement for a long list of original HP part numbers including 633733-151, 633805-001 and HSTNN-LB2R, and fits compatible ProBook models such as the 4330s, 4430s, 4440s, 4530s, 4535s, 4540s and 4545s series.

Check your original part number first

Before ordering, remove the old pack and confirm its part number matches one of the listed codes such as 633733-241, 633733-251 or 633809-001. Verify that the original voltage reads 10.8V and that the physical shape aligns with the six-cell form factor used in the noted ProBook families.

Steady output with built-in protection

A smart control chip manages charge current to reduce heat during extended use and supports longer discharge cycles. The pack includes short-circuit, overheat and overload safeguards that keep voltage stable throughout a full work session rather than only in brief bursts.
