Genuine replacement for HP Envy X360 15-inch series

This Hecales LK03XL battery replaces the original 3-cell lithium-ion pack used across multiple HP Envy X360 15-bp, 15-bq, 15-cn and 15-cp convertible models. It supplies 11.55V and 55.8Wh capacity from new grade-A cells with an integrated smart chip.

Suits owners of listed Envy X360 convertibles

Buyers whose laptop model is not in the compatibility list should look elsewhere, as the connector and firmware handshake differ between chassis generations. The pack is not designed for non-Envy HP lines or for devices requiring a 4-cell or 6-cell form factor.

55.8Wh energy rating matches the factory

The 4835mAh cell stack at 11.55V restores the original runtime envelope without requiring BIOS updates or hardware changes. Safeguard circuitry protects against incorrect voltage, short circuit and internal overheating during charge and discharge cycles.

Questions about this item

What does the 55.8 Wh rating mean for daily use on an HP Envy X360?

The 55.8 Wh capacity typically provides several hours of mixed workload on compatible Envy X360 models before needing a recharge.

How does the 11.55 V specification affect compatibility with the laptop's power system?

The 11.55 V output matches the original design voltage for the listed Envy X360 series, so the battery connects directly without adapters.

Will the three-cell pack fit the internal bay of a 15-bp or 15-bq chassis?

Yes, the 3-cell form factor is built to the same dimensions as the original LK03XL battery for those chassis.
