Questions about this item

Does the Dr. Battery MPL08251P-16 include any cables or tools, or is it just the battery?

The package contains the 6-cell lithium-ion battery only. No AC adapter, screws, or installation tools are supplied, so reuse the hardware from your original HP ProBook battery.

I see several HP ProBook series listed — 4330s, 4430s, 4530s and others — how do I pick the right one?

Match the original part number on your old battery (for example 633733-151, 633733-241 or HSTNN-LB2R) to the compatibility list. Voltage must be 10.8 V and capacity 4400 mAh.

What does the 4400 mAh rating actually give me in daily use on a ProBook 4540s?

At 10.8 V the pack stores roughly 48 Wh. Typical office workloads on a ProBook 4540s draw 15–25 W, so expect about two to three hours of unplugged runtime.
