This 53Wh lithium-ion battery fits the EliteBook x360 830 G7 and G8 series. It replaces part numbers including CX03XL, HSTNN-LB8R and HSTNN-IB9G. The unit ships new in black with a 12-month warranty.

Voltage and capacity limits

The cell delivers 11.55V and 53Wh, matching the original specification for the convertible series. It will not power the standard EliteBook 830 G7 or G8 models, which use a different battery design.

Verify exact model before ordering

Check the product label on the bottom of the laptop to confirm it reads EliteBook x360 830 G7 or G8. The standard clamshell 830 G7 and G8 are not supported, so installing this battery in those chassis will not work.

Questions about this item

Does the 53Wh capacity mean longer run-time than a lower-Wh battery?

Yes — 53Wh at 11.55V stores more energy, so it typically extends unplugged use compared with a lower-capacity pack.

Will this 11.55V pack charge correctly in my EliteBook x360 830 G7?

The voltage matches the original CX03XL specification, so the laptop's charging circuit will accept it normally.

Is the connector on this HSTNN-LB8R unit the same as the factory battery?

It replaces part numbers including HSTNN-IB9G and L78551-005, so the physical connector is identical.
