Product identity

This PISKEKAT VI04 is a 14.8 V lithium-ion replacement battery rated at 38 Wh with four cells. It is built for owners of compatible HP ProBook 440 G2, 445 G2, 450 G2, 455 G2 and Envy M7 series notebooks who need a direct spare for the original pack.

Interface limits

The pack uses the proprietary HP connector and form factor listed under part numbers such as 756743-001, 756478-421 and HSTNN-LB6K, so it fits only the models named in the compatibility data. It will not work in laptops that require a different voltage, pin layout or physical shape.

Deciding specification

The 38 Wh capacity determines whether this unit matches the runtime of the original battery; buyers should confirm their current pack carries the same watt-hour rating before ordering.

Questions about this item

Is the VI04 battery sold in any other capacity or cell count besides the 38Wh 4-cell version?

The VI04 is offered only as a 38Wh, 2600mAh, 4-cell lithium-ion pack at 14.8V. No alternative capacities or cell configurations are listed for this model.

What runtime can I expect from the 38Wh rating in a real laptop?

A 38Wh pack typically delivers several hours of mixed office work on a 14–15 inch HP ProBook or Envy, though actual time varies with screen brightness, CPU load and battery age.

Does the battery use a proprietary connector or a standard interface, and what does that limit?

The VI04 uses the same keyed multi-pin connector as the original HP spare parts listed, so it fits only the compatible ProBook, Pavilion and Envy models; it is not interchangeable with other brands or voltages.
