Replacement Battery for HP Pavilion 14-AL 14-AV

This 42WHR lithium-ion unit replaces the original SE03XL battery in compatible HP Pavilion 14-AL, 14-AV and 15-AU laptops. It delivers 11.55V from three cells and is certified to CE, FCC and RoHS standards.

Suitable for owners restoring factory runtime

Buyers needing a direct swap for a worn or failed OEM pack will find the correct voltage, capacity and connector. Users whose laptops require a different part number or a higher-watt-hour design should verify compatibility before purchasing.

3636mAh capacity for everyday workloads

The 42WHR rating supports typical office, browsing and media tasks for a full session. Heavy multi-core workloads or extended unplugged use will deplete the pack more quickly, so keep a charger handy for long days.

Questions about this item

Do I need the original HP SE03XL or 849908-850 part number to confirm this battery will fit my Pavilion 14-AL?

This battery replaces OEM numbers SE03XL, SE03041XL, HSTNN-UB6Z, 849908-850 and 849568-541, so matching any of those on your old pack confirms fit.

Will the 11.55V 3-cell design work with the charging circuit in my older Pavilion 15-AU that used a different voltage pack?

The replacement is built to the same 11.55V specification as the original SE03XL, so the laptop's existing charging controller manages it without modification.

How can I verify the 42WHR capacity is reporting correctly after I install the battery?

Check the full charge capacity in the OS battery report or BIOS; it should read close to 42WHR when new and the voltage should show 11.55V.
