41.9Wh 11.55V replacement battery for HP Pavilion

This 3-cell lithium-ion battery supplies 41.9Wh at 11.55V and is rated for up to 500 recharge cycles. It replaces the original HT03XL or L11119-855 pack in compatible HP Pavilion 15-CS, 15-CW, 15-DA, 15-DB, 15-DW, 15-DY, 15-CR, 14-CE, 14-DK and 14-DQ series notebooks. The unit is new and ready to install.

Check your current part number

Verify that the existing battery carries part number HT03XL, HTO3XL or L11119-855, or one of the listed alternates such as 920046-121, 920046-421 or 920046-541. Confirm the laptop model appears in the supported series above, as 17-inch BY and CA models are also included while other HP lines are not. Ensure the voltage and cell count match the original specification.

No extra accessories or software are bundled

The package contains only the battery itself; no tools, screws, cables or calibration utilities are supplied. Installation relies on the notebook’s existing latch or screw mechanism and the system’s built-in battery management. Users must follow the laptop manufacturer’s replacement procedure to complete the swap safely.
