What this battery replaces

This PISKEKAT unit is a new lithium-ion laptop battery built to replace HP part numbers 756743-001, 756745-001, 756478-421, 756479-421, 756478-422, HSTNN-DB6K, HSTNN-DB6J, HSTNN-LB6K and HSTNN-LB6I. It fits HP ProBook 440 G2, 450 G2 and TPN Q139, Q140, Q141, Q142, Q143 models as well as HP Envy 14, 15, 17 and Pavilion 15, 17 series notebooks.

The specification that decides fit

The pack delivers 14.8 volts from four cells and is rated at 2200 milliampere-hours. Those three figures — voltage, cell count and capacity — must match the original battery exactly or the notebook will not recognise the pack.

What the pack needs around it

No cables, adapters or firmware updates are required; the battery slots into the existing bay and connects to the stock motherboard header. It frees the user from a worn-out cell that no longer holds charge and restores up to 500 recharge cycles of mobile operation. Buyers whose laptop uses a different voltage or connector cannot use this pack.

Questions about this item

What does the 2200mAh rating mean for daily use on an HP ProBook 440 G2?

The 2200mAh capacity at 14.8V provides the energy storage the original 756743-001 supplied, so runtime matches the factory specification for that notebook.

Which connector standard does the 756743-001 replacement use and what does it limit?

It uses the same proprietary HP connector as the HSTNN-DB6K and HSTNN-LB6K packs, so it only fits models listed such as ProBook 440 G2, 450 G2 and Envy 14, 15, 17 series.

What physical space and mounting does the 4-cell pack need?

The 4-cell brick matches the original 756743-001 dimensions and screw-hole pattern, so it slides into the battery bay of compatible HP ProBook and Envy chassis without modification.
