Replacement battery for Spectre x2 12

This 42Wh lithium-polymer battery replaces the original ML03XL pack in HP Spectre x2 12 removable PCs. It delivers 11.4V and 3570mAh in a black housing. The unit is supplied new and matches part numbers 813999-1C1 and 814277-005.

Steady discharge at 11.4V

The cell chemistry maintains a stable 11.4V output during continuous workloads rather than only in short bursts. Rated capacity of 42Wh supports extended mobile sessions without sudden voltage sag. Internal protection circuits manage thermal limits during sustained draw.

Single-pack form factor constraint

The battery fits only the listed Spectre x2 12 models such as TPN-Q165, 12-A001DX, 12-A012TU and 12-A011TU. It cannot power devices that require a different voltage, connector layout or physical envelope. Buyers needing higher capacity or a different voltage must select another part.

Questions about this item

How much heat does the 11.4V 42Wh Li-polymer battery generate during all-day use?

The battery itself produces negligible heat; warmth you feel comes from the laptop's processor and charging circuit, not from the 3570 mAh cell.

What must I already own for this ML03XL battery to work in my Spectre x2 12?

You need a compatible HP Spectre x2 12 model such as the A001DX, A011TU or A012TU and a small Phillips screwdriver to open the case.

Will this 42Wh replacement behave the same as the original battery in my older Spectre x2 12?

Yes, it matches the original 11.4V 42Wh specification and fits the same part numbers ML03XL, HSTNN-IB7D, 813999-1C1 and 814277-005.
