NShi RU03XL 48Wh laptop battery

SKU CH-1WXF-2CFTG MPN RU03XL

48Wh 11.4V lithium-ion replacement battery for HP ProBook x360 11 G3-G6 and x360 440 G1 models

  • Battery typeLithium Polymer
  • 48Wh capacity extends runtime on compatible HP ProBook models
  • 4V lithium-ion chemistry delivers stable current with low self-discharge
  • Certified to CE, FCC and RoHS standards for safe operation
  • Replaces multiple OEM part numbers including RU03XL and HSTNN-IB8P
  • Fits HP ProBook x360 11 G3 through G6 and 440 G1 series

Compatible HP ProBook x360 models

This 48Wh lithium-ion battery replaces part numbers including RU03XL, HSTNN-IB8P and HSTNN-UB7P. It fits HP ProBook x360 11 G3 through G6 Education Edition units and the x360 440 G1 series. The 11.4V pack uses Grade-A cells and carries UL, CE, FCC and RoHS certification. Buyers needing a different voltage or connector layout cannot use this unit.

Sustained discharge and calibration

The smart chip regulates stable current and limits self-discharge during daily cycling. For optimal capacity the maker advises discharging to 5 percent then charging fully, repeating the cycle three to four times. Continuous heavy loads will deplete the 4212mAh reserve at a rate proportional to the notebook's power draw. Systems that demand more than 48Wh between charges will see shorter runtime.

Upgrade from 30Wh original equipment

Many factory configurations shipped with a 30Wh battery; this 48Wh version increases stored energy by 60 percent. The swap is worthwhile when the original pack no longer holds charge or when longer unplugged sessions are needed. Machines outside the listed ProBook x360 families, or those requiring a different part number, are not supported.

Questions about this item

Does the 11.4 V lithium-polymer pack run hot during all-day use?

The battery is certified to CE, FCC and RoHS standards and uses Grade-A cells designed for low self-discharge and stable current, which keeps heat low under normal loads.

Will the existing connector on my HP ProBook x360 11 G4 match the RU03XL?

The replacement shares the same connector layout as part numbers HSTNN-IB8P, HSTNN-UB7P and L12717-1C1; verify the photo before fitting.

Can I keep my original 30 Wh charger when I swap to this 48 Wh unit?

Yes, the 11.4 V voltage is identical, so the existing AC adapter will charge the higher-capacity pack without issue.
