Drop-in replacement for HP ProBook X360

The NShi RU03XL is a new 3-cell lithium-ion pack rated at 11.4 V and 48 Whr. It matches the original part numbers for HP ProBook X360 11 G3, 11 G4 and 440 G1 models including EE variants. Install it directly in place of the factory battery to restore mobile runtime. No adapters or firmware steps are required.

Thermals and power draw in normal use

The lithium-ion chemistry delivers stable current with low self-discharge during daily workloads. Each unit is tested for correct voltage, circuit protection and consistent output before shipping. CE, FCC and RoHS certifications confirm compliance with safety and emissions standards. Typical operation stays within the thermal envelope of the original design.

Build integration and what it frees up

The pack fits the existing battery bay without chassis modifications or extra cabling. Replacing a worn cell restores untethered use for education or field deployments. It does not add charging circuits, increase capacity beyond the 48 Whr rating or support models outside the listed ProBook X360 series. Buyers needing higher capacity or a different voltage must choose another part.

Questions about this item

How do I install this RU03XL 11.4V 48Whr battery in my HP Probook X360 11 G3, and what step is often missed?

Power off the laptop, disconnect the AC adapter, remove the bottom case screws, detach the old battery connector from the motherboard, fit the new 3‑cell pack, reconnect the cable firmly, then reassemble; the step most often missed is reconnecting the battery cable before closing the case.

What maintenance or replacement will this 4210mAh lithium‑ion pack need later?

The 3‑cell lithium‑ion pack will gradually lose capacity over time; when run‑time drops below your needs, replace it with another compatible 11.4V 48Whr unit such as part numbers L12791‑855 or HSTNN‑UB7P.

What limit appears first under sustained heavy load on this 11.4V 3‑cell battery?

Under sustained heavy load the 48Whr capacity is the limiting factor — runtime shortens until the pack reaches its low‑voltage cutoff and the laptop shuts down.
