The 11.4V 45Wh rating must match the original specification printed on your existing pack. If the label on your current battery shows a different voltage or watt-hour value, this unit will not work correctly in your device.

Questions about this item

How can I confirm the RH03XL is working correctly after installing it in my HP ProBook 440 G8?

The battery should charge to 100% in the OS power meter and report 11.4V and 45Wh capacity; run a discharge cycle to verify runtime matches the 3947mAh rating.

What comes with the RH03XL battery and what must I purchase separately for my HP Zhan 66 Pro 14 G4?

The package includes the 11.4V 45Wh Li-ion battery only; no tools, screws or AC adapter are supplied, so reuse the original charger and any mounting hardware from the old pack.

Which RH03XL version should I choose for an HP ProBook 650 G8 versus a ProBook 430 G8?

The single RH03XL part number RH03XL HSTNN-IB9P HSTNN-OB1T TPN-DB0B fits both the 650 G8 and 430 G8, so select this one model for either laptop.
