HT03XL 11.55 V 41.9 Wh Replacement Battery

The HT03XL is a new lithium-ion battery rated at 11.55 V and 41.9 Wh. It replaces the original power pack in numerous HP Pavilion 14, 15 and 17 inch models including the 14-CE, 14-CF, 15-CS, 15-DA, 15-DB, 17-BY and 17-CA series. Buyers who need a higher capacity cell or a different voltage will not be served by this part.

Direct-fit design limits installation to listed

The battery matches the factory form factor and connector layout for the part numbers HT03XL, HSTNN-DB8R, HSTNN-UB7J, L11119-855 and L11421-542 among others. It cannot be used in laptops outside the specified Pavilion families because the keying and pin-out differ. Systems that require a 3-cell or 6-cell pack with a different watt-hour rating are not compatible.

Black housing with included screwdrivers eases

The pack ships in a black enclosure and the box contains one HT03XL battery, a user manual and two screwdrivers for immediate installation. No specialised tools are required beyond the supplied drivers. The rechargeable cell delivers 3685 mAh at the rated voltage. Units that need an external charger or a proprietary docking connector are not supported.

Questions about this item

What does the 41.9 Wh rating mean for daily use?

The 41.9 Wh capacity stores enough energy for several hours of typical office tasks on a compatible HP Pavilion laptop.

Which HT03XL version matches my specific Pavilion model?

Check your laptop's exact model number against the supported list — 14-CE, 14-CF, 14-DF, 15-CS, 15-DA, 15-DB, 15-DW, 17-BY or 17-CA series — and match the original part number such as L11119-855 or HSTNN-UB7J.

What voltage does this battery operate at and what does that limit?

It operates at 11.55 V, which is fixed by the cell chemistry and must match the laptop's power rail; the system will not accept a different voltage.
