What this battery is and who it fits

This is a brand-new Li-ion polymer replacement battery rated at 11.55V and 55.8Wh with three cells. It is built to replace the LK03XL pack used in select HP Envy x360 convertible notebooks across the 15-inch and 17-inch series. The unit carries a 500-plus recharge-cycle rating and includes built-in circuit protection for stable output.

What to verify on your laptop before ordering

Sub-model variations exist inside every listed series, so the series name alone does not guarantee fit. Open the back cover if possible and read the model number printed on your original battery; it must match LK03XL or one of the listed part numbers such as 916814-855, HSTNN-LB7U or TPN-W127. Confirm the voltage and cell count on the label match 11.55V and three cells before purchasing.

Who this suits and who should look elsewhere

This pack suits owners of compatible HP Envy x360 15-BP, 15-BQ, 15-CN, 15M-CP, 17-AE and 17M-AE models whose original battery carries a matching part number. Buyers who cannot locate or read the original battery label should not order, as visual similarity does not guarantee electrical compatibility. Anyone needing a different voltage, capacity or form factor must choose another product.

Questions about this item

What is included with the LK03XL battery and what must be purchased separately?

The package contains the LK03XL 3-cell Li-ion polymer battery rated at 11.55V and 55.8Wh. No tools, screws, cables or installation guides are supplied; those must be sourced separately.

Which part number should I match to ensure the correct LK03XL version for my HP Envy x360?

Open the back cover and compare the printed code on your original battery against the compatible list: LK03XL, L09281-855, 916814-855, HSTNN-LB7U, HSTNN-LB8J, HSTNN-UB71, TPN-W127, TPN-W128 or TPN-I129.

What does the 55.8Wh rating mean for daily runtime on an Envy x360 15m or 17m?

At 11.55V the pack stores 55.8Wh, which typically delivers several hours of mixed use on compatible 15-BP, 15-BQ, 15-CN, 15M-CP or 17-AE series notebooks before needing a recharge.
