Replacement for HP EliteBook x360 1030 G3 G4

This 7.7V 56.2Wh lithium-ion battery replaces the original BM04XL unit in HP EliteBook x360 1030 G3 and G4 series notebooks. It matches the 7300mAh capacity and voltage of the factory pack. The compatible part numbers include HSTNN-UB7L, L02031-541, BM04056XL and L02478-855.

Upgrade from degraded or failed original cells

When the original battery no longer holds a useful charge or the notebook shuts down unexpectedly, this new pack restores full runtime. The jump is worth it if the laptop still meets your performance needs but the battery health has dropped below a usable threshold. Connector geometry can vary between production batches, so verify the interface against the product images before ordering.

Behaviour under sustained daily cycling

Lithium-ion chemistry delivers stable voltage through the discharge curve rather than a sharp drop-off near empty. The manufacturer advises an initial conditioning routine: discharge to five percent, then complete a full charge cycle three to four times to wake the cells. After conditioning, the pack maintains consistent output during extended unplugged sessions. Not suited for users who need a higher-capacity alternative or a different form factor.

Questions about this item

Will the BM04XL battery fit my HP EliteBook x360 1030 G3 G4 series notebook?

This battery replaces part numbers BM04XL, BMO4XL, HSTNN-UB7L, L02031-541, BM04056XL and L02478-855 for the HP EliteBook x360 1030 G3 G4 series. Check the connector in the product image against your original battery because size, cable length and interface can vary between factories.

What is the correct first-time installation step for the BM04XL battery?

If the new battery is not recognised, reinstall it and verify the interface is fully connected. Then discharge to 5 percent, not zero, and complete three to four full charge cycles to wake up the cells.

How long will the 7.7 V 56.2 Wh lithium-ion battery last before it needs replacement?

Lithium-ion cells typically deliver several hundred full charge cycles before capacity drops noticeably. Calibrating by cycling to 5 percent and recharging every few months helps maintain accuracy and prolongs useful life.
