Replacement battery for HP Pavilion 15-AU series
This lithium-polymer battery replaces the original HP BP02XL and HSTNN-LB7H packs used in multiple Pavilion 15-AU models. It supplies 7.4 volts and 4900 mAh capacity for compatible laptops. The pack is new and includes a smart control chip that manages charging and protects against short circuit, overheat and overload.
Practical limits of the 7.4 V lithium-polymer
The cell chemistry delivers a nominal 7.4 volts with a rated 38 watt-hours of energy. Voltage is fixed by the two-cell series design so the pack cannot be used in laptops that require a different voltage. The smart chip enforces safety cut-offs that stop charging or discharging if temperature or current exceed internal thresholds.
Capacity and headroom for daily workloads
At 4900 mAh the battery provides enough charge for typical office tasks, web browsing and media playback on supported Pavilion 15-AU units. Runtime will fall when the system drives high-performance graphics or sustained processor loads. The pack is not suited for users who need all-day operation without access to mains power.

Questions about this item
What is the difference between the 4900 mAh and 4935 mAh capacity figures?
The 4900 mAh value is the rated capacity printed on the battery label, while 4935 mAh is the manufacturer's typical capacity measured under test conditions; both refer to the same 7.4 V lithium polymer cell.
How long will a 4900 mAh 7.4 V battery last in an HP Pavilion 15-AU144TX?
The 38 Wh energy rating translates to roughly 3 to 5 hours of mixed office use on that model, depending on screen brightness, background apps and battery age.
Does this battery use the standard HP Pavilion 15-AU charging interface?
Yes, it matches the original BP02XL / HSTNN-LB7H pin-out and 7.4 V output, so the laptop's built-in charge controller manages it without any adapter.
