Compatible HP Pavilion Replacement

The No Sew HT03XL is a lithium-ion laptop battery built to replace the original HP L11119-855 unit. It fits a wide range of Pavilion 14, 15 and 17 series models listed in the compatibility data. The pack ships new and ready to install.

Voltage And Capacity Details

Rated at 11.55 V with 41.9 Wh and 3470 mAh, the three-cell design delivers the same energy budget as the factory battery. It powers typical office workloads for a full session and handles media playback without unexpected shutdowns. Runtime falls off under sustained heavy loads such as gaming or video rendering.

Lithium-Ion Chemistry Limits

The lithium-ion cells self-discharge slowly when the notebook is stored for weeks, so a top-up charge is advised before long trips. Capacity fades gradually after several hundred charge cycles, eventually requiring another replacement. Extreme heat or deep discharge accelerates that ageing process.

Questions about this item

Will the HT03XL 11.55V 41.9WH battery fit my HP Pavilion 15-DB0015DX alongside the original charger?

Yes, the battery replaces part numbers HSTNN-DB8R and L11119-855 used in the 15-DB series, so it works with the existing HP charger.

How can I confirm the new HT03XL battery is charging correctly after installation?

The laptop should show the battery icon charging to 100 % and report 11.55 V / 41.9 Wh in the BIOS or HP Support Assistant.

Does the box include only the HT03XL battery or also screws and tools for the 14-CF series?

You will get one HT03XL battery; screws and opening tools are not included and must be sourced separately.
