Replacement battery for EliteBook X360 1020 G2

This NShi HSTNN-IB7U lithium-polymer battery replaces the original HP ET04XL unit. It delivers 7.7V and 49.81Wh capacity at 6470mAh. The pack is designed for the EliteBook X360 1020 G2 and HSN-I09C series laptops. Installation is a plug-and-play process once the correct model is confirmed.

Capacity limits for daily workloads

The 49.81Wh rating sets a hard ceiling on runtime between charges. Heavy multi-tasking or high screen brightness will draw the 6470mAh reserve down faster than light document work. Lithium-polymer chemistry degrades gradually, so maximum usable capacity will decline over repeated cycles. Users needing all-day operation away from mains power should plan for mid-day recharging.

Internal fit and connector layout

The black battery housing matches the OEM form factor for the X360 1020 G2 chassis. A direct-plug connector aligns with the motherboard header, requiring no adapter cables. Screws secure the pack once the bottom case is removed, so a small Phillips driver is the only tool needed. Verifying the original part number — 915191-855 or 915030-1C1 — before purchase avoids ordering a unit that will not seat correctly.

Questions about this item

Should I pick the 49.81Wh or 6470mAh rating when choosing this battery?

Both figures describe the same cell; 49.81Wh is the energy capacity and 6470mAh is the charge capacity at 7.7V, so they are interchangeable for this model.

What does the 49.81Wh rating actually deliver in the EliteBook X360 1020 G2?

It restores the original 49.81Wh capacity, giving the same run-time the laptop had with its factory battery under identical workloads.

Does the plug-and-play connector match the HP HSN-I09C interface used in the 1020 G2?

Yes, the battery is built to the HSN-I09C pin-out and voltage, so it connects directly without adapters or firmware changes.
