Questions about this item

Does the SX03XL battery require any additional cables or adapters to install in an HP ProBook x360 435 G7?

No extra cables are needed; the SX03XL connects directly to the laptop's internal battery connector using the existing motherboard interface.

Will the 11.55V 45Wh SX03XL work alongside the original AC adapter that came with my ProBook x360 435 G8?

Yes, the battery is designed to charge from the laptop's original charger at the same 11.55V rating, so the existing adapter remains fully compatible.

How can I verify the SX03XL is functioning correctly after installation?

The laptop should recognise the battery immediately, show a charge level in the OS, and reach a full charge using the original charger, indicating the built-in protection circuit is operating normally.
