Replacement battery for HP Pavilion 14 and 15 series

The PISKEKAT HT03XL is a 3-cell lithium-ion laptop battery rated at 11.55 volts with a capacity of 41.9 watt-hours and 3630 milliampere-hours. It serves as a direct replacement for the original HT03XL and a long list of compatible part numbers including L11119-855, HSTNN-UB7J, HSTNN-DB8R and many others. The unit is supplied new, built with quality cells and a smart protection circuit. It fits numerous HP Pavilion 14-CE, 14-CF, 14-DF, 15-CS, 15-DA, 15-DB and 15-DW models among others.

Verify the exact part number before ordering

Check the label on your current battery or the HP service manual to confirm that your original part number matches one of the compatible codes such as HT03XL, L11119-855, HSTNN-UB7J, HSTNN-LB8M or L11421-542. Several different batteries look similar but carry different voltages or connector layouts, so visual inspection alone is not reliable. Ensure the laptop model appears in the supported series list, for example 14-ce0xxx, 14-cf0xxx, 15-cs0xxx or 15-da0xxx, before proceeding.

Steady output through a full discharge cycle

The 3-cell lithium-ion chemistry delivers a stable 11.55 volt nominal voltage across the discharge curve, avoiding the sharp voltage drop that can trigger early shutdowns under load. The integrated smart chip monitors cell balance and temperature continuously, maintaining consistent current delivery during extended sessions such as video playback or document work. Rated capacity of 41.9 watt-hours supports typical mixed-use workloads for several hours depending on screen brightness and peripheral activity.

How do I know whether the 41.9 Wh version matches my Pavilion model?

What runtime can I expect from the 3630 mAh rating in a Pavilion 15-CS?

The 3630 mAh capacity at 11.55 V restores the original 41.9 Wh design, giving the same battery life the laptop had when it was new.
