Questions about this item

What laptop models must I already own for the LK03XL 11.55V 52.5Wh battery to fit?

The battery fits HP Envy X360 15-BP, 15-BQ, 15-CN, 15-CP, 15-CR, 17-AE and 17-CE series laptops, including models such as 15-bq100, 15-bq101ng, 17-ae000 and 17-ae111DX.

Will the 11.55V LK03XL battery work alongside the original 916814-855 or L09281-855 part that came in my Envy X360?

Yes, the LK03XL replaces part numbers 916814-855, L09281-855, HSTNN-LB8J and all other listed OEM codes, so it works as a direct swap for the original battery.

How can I confirm the 52.5Wh LK03XL is working correctly after I install it?

After installation the laptop should power on without the AC adapter, the OS battery meter should show a capacity near 52.5Wh at full charge, and the battery should hold charge through normal use.
