Replacement battery for HP Spectre X360 15-BL000

This 6-cell lithium-ion battery replaces the original pack in HP Spectre X360 15-BL000, 15-BL0XX, 15-BL000NA, 15-BL000NG and 15-BL001NA models. It delivers 11.55V and 79.2W capacity for a direct fit. The unit is new and carries CE and RoHS certification. Buyers needing a different voltage or cell count should look elsewhere.

Sustained discharge at 11.55V across six cells

The lithium-ion chemistry maintains a steady voltage curve during long work sessions, reducing the sharp drops seen in worn packs. Rated at 79.2W, the capacity supports extended multimedia playback and document editing without frequent recharging. Consistent cell balancing helps preserve runtime over the full discharge cycle. It is not suited for users who require hot-swap capability or external charging cradles.

Thermal behaviour and power draw in daily use

The pack operates within normal laptop thermal limits during typical office and streaming loads. Lithium-ion construction keeps self-discharge low when the system sleeps, preserving stored energy between sessions. No active cooling is required beyond the notebook's own chassis airflow. The one-year replacement warranty covers defects in materials and workmanship.
