Compatible replacement battery

The PowerWarehouse N59787-005 is a new lithium-ion battery built for HP EliteBook 830 G11, 835 G11, 840 G11, 845 G11, 860 G11 and 865 G11 notebooks. It replaces OEM part numbers BX03XL, N59733-AC1, HSTNN-OB3H, N59787-002, BX03056XL-PL and BX03056XL. This unit suits owners of those specific G11 models who need a direct swap.

Voltage and capacity match

The cell delivers 11.58 V and 4840 mAh, matching the original electrical specification so the laptop’s power management recognises it without calibration issues. Buyers whose EliteBook requires a different voltage or a higher capacity cell will not be served by this part.

Thermal and power behaviour

In normal operation the battery runs at the same voltage and current profile as the factory pack, so heat output and discharge rate remain identical to the OEM unit. No additional cooling or power-budget changes are required for the supported EliteBook G11 chassis.

Questions about this item

How long will the 4840mAh capacity last on a full charge in an EliteBook 840 G11?

Runtime depends on workload and screen brightness; the 4840mAh rating matches the original BX03XL specification for comparable battery life.

What connector standard does the N59787-005 use and does it limit charging speed?

It uses the same multi-pin connector as the OEM BX03XL, so charging speed is governed by the laptop's built-in controller, not the battery.

Will this battery fit the EliteBook 865 G11 without modification?

Yes, the N59787-005 is listed as compatible with the 865 G11 and matches the physical dimensions of the HSTNN-OB3H pack.
