Replacement battery for HP EliteBook and ZBook

The PISKEKAT SS03XL is a 50Wh lithium-ion pack rated at 11.55V with three cells. It replaces a long list of HP part numbers including SS03XL, 933321-855 and HSTNN-LB8G.

Sustained operation and safety

Built-in protection circuits guard against short circuit, over-voltage, over-current and deep discharge during extended use. The cell assembly has passed CE, FCC and RoHS certification and each unit is tested to meet OEM specifications. These safeguards help maintain stable output over long work sessions and protect the battery’s usable cycle life.

Compatibility checklist before ordering

Verify that the original battery part number matches one of the referenced codes such as 932823-171 or HSN-113C-4. Ensure the laptop’s battery bay accepts a three-cell 11.55V form factor before purchase.

Questions about this item

Does the 50Wh 11.55V 3-cell battery run hot or noisy under continuous load?

Lithium-ion cells produce no audible noise and minimal heat during normal operation; built-in over-current and over-voltage protection limits temperature rise during extended use.

Must I already own a compatible HP EliteBook or ZBook model for this SS03XL pack to work?

Yes — it replaces part numbers SS03XL, 933321-855, 932823-171 and others listed for EliteBook 840/830/730/735/740/745 G5-G6, ZBook 14U G5-G6 and MT44.

Will this 11.55V replacement work alongside the original charger and BIOS on an older EliteBook G5 unit?

The pack matches the factory 11.55V 50Wh spec and carries CE, FCC and RoHS certification, so the existing AC adapter and system firmware recognise it without modification.
