Replacement Battery for HP Envy X360 Convertible

The No Sew LK03XL is a 55.8Wh 11.55V 3-cell lithium polymer battery built for HP Envy X360 convertible models including 15m-cn, 15m-bp, 15m-bq, 17m-ae and 17-bw series. It replaces part numbers such as L09281-855 and 916814-855. The pack measures 10.5 in by 4.8 in by 0.67 in and weighs 0.26 kilograms. It ships with two screwdrivers and an instruction sheet.

Straightforward Swap with Basic Tools

Installation requires only the included screwdrivers to remove the bottom case screws and disconnect the old battery cable. The connector matches the original LK03XL layout so no adapter is needed. The most common issue is forgetting to detach the cable before lifting the pack which can strain the motherboard header. Follow the supplied guide and reconnect firmly to avoid a no-post condition.

Verify Your Exact Model and Part Number

Before ordering confirm that your laptop model appears in the compatible list such as 15m-cn0012dx 15m-bp112dx or 17-bw0013dx and that the original battery carries a part number like LK03XL L09281-855 or 916814-855. Voltage must read 11.55V and capacity 52.5Wh or 55.8Wh on the label. This battery is not for HP Envy models outside the listed series or for units requiring a different voltage or cell count.
