Cameron & Co DS-CS-HUT190NB laptop battery 7.6V 4300mAh

Direct replacement for Huawei MateBook

This Cameron & Co DS-CS-HUT190NB battery replaces the original HB25B7N4EBC unit in HZ-W19 and MateBook laptops. It is a brand-new lithium-polymer pack rated at 7.6 V and 4300 mAh, delivering 32.68 Wh of capacity. The slim black cell measures 232.94 x 116.02 x 2.55 mm and fits the factory battery bay without adapters.

Fits the original chassis and connector

The pack uses the same form factor and connector as the Huawei original, so installation only requires removing the bottom cover and swapping the cable. No soldering, shims or firmware updates are needed, and the 100 % OEM-compatible design keeps the existing charge-management circuitry in control. This restores full mobility without altering the laptop's thermal or mechanical layout.

Steady output through a full workday

Lithium-polymer chemistry provides a flat discharge curve, so voltage remains stable from the first minute to the last percent of the 32.68 Wh rating. The cell sustains the notebook's normal load without the sharp voltage sag seen in aged packs, avoiding unexpected shutdowns during sustained productivity tasks. Capacity retention stays consistent over repeated charge cycles when the system's built-in management is used.
