Replacement battery for HP Pavilion series

The 2-Power HT03XL is a new lithium-ion battery built to replace the original power pack in a wide range of HP Pavilion 14, 15 and 17 inch notebooks. It matches the OEM part numbers HT03XL, L11119-855 and HSTNN-UB7J among others. Owners of compatible models can restore full mobile runtime without adapting cables or brackets.

41.7 Wh capacity at 11.55 V across three cells

The pack stores 41.7 watt-hours and 3470 milliampere-hours at a nominal 11.55 volts using three lithium-ion cells. In normal use it delivers steady voltage for everyday office work, streaming and light multitasking. Power draw follows the laptop's own management; the battery adds no audible noise and produces only the warmth typical of a modern Li-ion cell under load.

Direct-fit design with original connector layout

The battery uses the same physical footprint and connector orientation as the factory unit, so it seats in the existing bay without modification. Screw holes align with the chassis mounts on listed Pavilion 15-DA, 15-DB, 15-DW, 15-DY, 17-BY and 17-CA models as well as 14-CE, 14-CF and 14-DF series. Buyers whose laptop requires a higher-capacity pack or a different voltage will need a different part number.

Questions about this item

How do I install the HT03XL battery and which step do people often get wrong?

Remove the bottom case screws, disconnect the old battery cable, fit the new 3-cell 11.55 V pack, reconnect the cable before refitting the case — the step most people miss is reconnecting the cable before the case goes back on.

What maintenance or replacement will the HT03XL need later?

The 41.7 Wh Li-ion pack will gradually lose capacity; plan to replace it once run-time drops below your needs — no user-serviceable parts inside.

What limit appears first during sustained use of the HT03XL?

The 3470 mAh capacity sets the runtime ceiling; under continuous load the battery will hit its discharge limit before any thermal throttle.
