HT03XL 11.4V 41Wh 3-cell laptop battery for HP Pavilion 14 15 17

11.4V 41Wh 3-cell battery for HP Pavilion

This 11.4V 41Wh lithium-ion battery fits HP Pavilion 14, 15 and 17 series notebooks including models 14-CE, 14-CF, 14-CM, 14-DH, 14-DQ, 14-DK, 14-FQ, 15-CS, 15-CW, 15-DA, 15-DB, 15-DW, 15-DY, 15-EF, 15S-FQ, 17-BY and 17-CA. It replaces the original HT03XL pack and supplies 3470 milliamp-hours across three cells. Buyers who need a 4-cell or 6-cell configuration, or a different voltage, cannot use this unit.

Straightforward internal swap

The pack installs by removing the bottom case screws, disconnecting the old battery cable and connecting the new one in the same orientation. No soldering or firmware update is required. Common issues are forgetting to detach the cable before lifting the old pack, which can strain the connector, and not reseating the connector fully, which leads to a no-charge condition. The 263-gram weight matches the original so the chassis balance is unchanged.

Steady output during long sessions

Rated at 11.4V and 41Wh, the cells deliver consistent voltage through extended workloads such as video rendering or large compiles without the sharp sag seen in aged packs. The three-cell layout spreads thermal load evenly, so the battery stays within normal operating temperature during multi-hour use. Capacity remains stable across repeated cycles because the lithium-ion chemistry is rated for hundreds of full charge-discharge sequences.
