Replacement 41.9Wh Li-polymer battery

This new POWER-FENG battery replaces the original HT03XL pack in compatible HP Pavilion 14 and 15 models. It delivers 11.55 V and 3630 mAh capacity in a black Li-polymer form factor. The part matches multiple HP service numbers including HSTNN-DB8R and L11119-855. Buyers needing a different voltage or capacity cannot use this unit.

Fits listed HP Pavilion 14-CE and 15-CS chassis

The battery slots directly into the existing bay without extra cabling or adapters. It restores mobile operation for machines identified by the supplied model list such as 14-CE0030TX and 15-CS0038TX. Systems outside the listed series will not recognise the pack. Installers must ensure the laptop chassis matches one of the declared model codes.

Sustained discharge at 11.55 V nominal

Under continuous load the Li-polymer cells maintain the rated 41.9 Wh until the pack reaches its low-voltage threshold. Capacity fade follows normal Li-polymer ageing rather than a sudden drop-off. The pack contains no active cooling, so thermal management relies on the laptop's internal airflow. Users expecting hot-swap capability or smart-fuel-gauge recalibration will not find those features here.

Questions about this item

How long will the 41.9Wh capacity last under continuous load?

The 41.9Wh rating indicates the total energy stored; actual runtime under sustained use depends on the laptop's power draw, which varies by model and workload.

Does the 11.55V Li-polymer battery run hot or noisy during all-day operation?

As a passive Li-polymer cell, it has no fan and produces no noise; heat output is determined by the laptop's internal charging circuit and workload.

Which HP Pavilion models are confirmed compatible with the HT03XL part number?

It replaces HT03XL and fits listed HP Star 14 and 15 series models including 14-CE, 14-EC and 15-CS ranges.
