Check your current battery part number

Before ordering, verify that the original battery in your laptop carries one of the listed OEM part numbers. Confirm the laptop model name on the service tag matches the compatibility list exactly. The connector layout and physical dimensions are designed for those part numbers only. A mismatch will prevent correct installation or charging.

Thermals and power in daily use

The 3-cell lithium-ion pack operates at 11.4 volts with a 3750 mAh capacity for typical office workloads. Normal charging and discharging cycles stay within standard thermal limits for the supported ProBook chassis. No active cooling is required beyond the laptop's own ventilation. The battery ships new and includes a 12-month warranty from the supplier.

Questions about this item

Does the battery arrive with any cables or tools, or must I buy them separately?

Only the battery itself is supplied; no cables, screws or tools are included.

How do I choose between the listed part numbers such as HSTNN-OB2X, RH03XL or M75599-005?

All listed part numbers refer to the same 3-cell 11.4 V 42 Wh pack; pick the one printed on your original battery.

What does the 42 Wh rating mean for daily runtime on a ProBook 440 G8?

The 42 Wh capacity matches the original specification, so expect similar run time to the factory battery when new.
