41.7 Wh replacement battery for HP Pavilion

This lithium-ion pack delivers 41.7 Wh at 11.55 V using three A-grade cells. It matches part numbers such as HT03XL, HSTNN-DB8R and L11421-542. The unit ships new in black and includes two screwdrivers for installation. It suits owners of compatible Pavilion 15, 17, 240, 245, 250, 255, 340 and 348 series laptops.

Steady discharge across a work session

The three-cell layout maintains a stable voltage curve during extended use rather than sagging after a short burst. Capacity remains consistent over repeated cycles because the cells are rated at one hundred percent new. No smart circuitry or fast-charge protocol is described in the data, so the pack behaves as a standard replacement under sustained load.

Limited to the listed HP part numbers

Compatibility is confined to the exact models and part numbers supplied; the battery will not fit laptops outside that list. Voltage and connector geometry are fixed, so adaptation to other brands or newer chassis is not possible. Buyers needing a different capacity, voltage or form factor must source an alternative pack.
