DMKAOLLK LK03XL 11.55V 52.5Wh 3-cell laptop battery

Replacement battery for HP Envy X360 15-bp 15-bq

This 11.55V 52.5Wh lithium-ion cell replaces the original LK03XL pack in HP Envy X360 convertible models across the 15-bp, 15-bq, 15-cn, 15m-bp, 15m-bq and 15m-cn families. It ships new with a set of screwdrivers so the swap can be done immediately. The three-cell black unit fits the same bay and connects to the same header as the factory battery. Overcharge, overdischarge, over-temperature and short-circuit protection circuits are built in.

Upgrade from a depleted or swollen original pack

When the factory battery no longer holds a useful charge or shows physical swelling, this direct-fit replacement restores full mobile runtime without adapting cables or brackets. The jump is worth it when the laptop must run unplugged for meetings, travel or classroom use and the old cell cannot sustain that workload. It matches the voltage and capacity the system expects, so the firmware reports capacity accurately and power-management profiles remain valid.

Sustained discharge with protection circuits active

Under continuous load the pack delivers its rated 52.5Wh while the onboard electronics guard against over-temperature and short-circuit events. The chemistry is rated for up to 500 recharge cycles over the life of the battery, so daily charge and discharge patterns remain stable for an extended period. Voltage stays at 11.55V nominal throughout the discharge curve, keeping the Envy X360's power regulation steady during long work sessions.
