Replacement Battery for HP Laptops

This 11.1V lithium-ion pack replaces the HP BQ350AA and compatible part numbers including BQ350AAABA, BQ350AAAC3, HSTNN-CB1A and HSTNN-CB1B. It is built for owners of those specific HP notebooks who need a new power source that matches the original voltage and connector layout. Buyers with different HP models or other brands cannot use this battery.

Sustained Output From Six Premium Cells

The 6-cell design delivers a rated 5200mAh capacity, allowing the laptop to run for extended periods on a single charge rather than only short bursts. Lithium-ion chemistry maintains stable voltage through the discharge curve, so performance stays consistent during long work sessions or media playback. The pack is CE and RoHS certified for safety and environmental compliance.

5200mAh Capacity Decides Fit For Your Needs

The 5200mAh rating is the single figure that determines whether this unit meets your runtime expectations. A higher or lower capacity would change how long the notebook operates away from mains power. If your workflow demands more stored energy than 5200mAh provides, this battery will not satisfy that requirement.
