Replacement Battery for HP EliteBook 830 G11

The KingSener BX03XL is a 100% brand-new lithium-ion replacement battery built for the HP EliteBook 830 G11 series. It delivers 11.58V and 4840mAh for 56.04Wh of capacity. The pack uses high-quality cells and a reliable PCB to match the original design specification.

Straightforward Swap With Break-In Steps

Installation follows the original battery layout, so the part fits the chassis without modification. The supplier recommends three full charge and discharge cycles at low current to condition the cells. Avoid leaving the AC adapter connected continuously during use and store the pack above 80% charge if removed for a month or longer.

Voltage and Capacity Confirm Compatibility

The decisive specification is the 11.58V output combined with 4840mAh capacity. Verify the original battery carries the same voltage and part numbers such as BX03XL, BX03056XL or HSTNN-UB9E before ordering. Buyers who need a different voltage or higher capacity should look elsewhere.
