Questions about this item

Which HP laptop models accept the LK03XL 11.55V 52.5WH battery?

The battery fits HP ENVY x360 15-BP, 15-BQ, 17-AE and 17-CE series plus the part numbers LK03XL, LK03048XL, LK03055XL, HSTNN-IB8M, HSTNN-LB7U, HSTNN-LB8J, HSTNN-UB7I, 916368-421, 916368-541, 916814-855, L09281-855 and others listed.

Will the 4-cell 11.55V pack work in an older HP that originally used a 3-cell battery?

No — the voltage and cell count must match the original specification; this pack is 11.55V with four lithium-ion cells and only replaces batteries with the same rating.

How can I confirm the new LK03XL battery is charging correctly after installation?

The laptop should show the battery detected at 11.55V and 52.5WH in the BIOS or OS power meter, and the charge percentage should rise steadily while the AC adapter is connected.
