The pack is engineered to work with part numbers 458274-361, 493976-001, 501114-001, 484788-001, HSTNN-LB60, HSTNN-XB60, HSTNN-I43C and HSTNN-W46C. No additional cables, software or adapters are included in the box. Installation uses the existing battery bay and connector on each compatible model.

Limited to 14.4V 8-cell form factor

The 14.4V output and 8-cell layout restrict use to the exact EliteBook models listed; other HP lines with different voltages or cell counts will not accept this pack. Capacity is fixed at 73WH, so runtime cannot be extended beyond the original design. Buyers needing a higher-capacity or different-voltage solution must select another product.

Questions about this item

How many cells will need replacing when this 8-cell pack wears out?

The pack contains eight lithium-ion cells rated at 73 Wh; when capacity drops you replace the whole 8-cell unit.

Will the 14.4 V output stay stable during a full workday?

The battery delivers a nominal 14.4 V and 73 Wh capacity, so voltage remains steady until the stored energy is depleted.

Does the 73 Wh pack run hot or loud under constant load?

Lithium-ion cells generate no fan noise; warmth scales with discharge rate but stays within normal operating limits for an 8-cell design.
