Replacement battery for HP Pavilion 15-AU series

This Dr. Battery MPL08318P-30 unit replaces the original pack in numerous HP Pavilion 15-AU models, including the 15-AU103NG through 15-AU147TX variants. It is built for owners who need a direct-fit, 7.4 V lithium-polymer cell rated at 4900 mAh. The black housing matches the factory aesthetic and installs without adapters.

Practical limits of a 7.4 V lithium-polymer pack

The chemistry delivers 38 Wh of energy at a nominal 7.4 V, with the supplier noting a 7.7 V device voltage and 4935 mAh capacity. Runtime scales with the laptop's actual power draw, so heavy workloads will deplete the charge faster than light browsing. The integrated smart chip manages charging current and discharge pacing, but it cannot overcome the fundamental energy ceiling of the cell.

Build quality and daily implications

A built-in protection circuit guards against short circuit, overheating and overload during everyday use. The lithium-polymer pouch format keeps the pack slim for the Pavilion chassis, and the black finish resists visible wear. Buyers who need a higher-watt-hour option or a different voltage should look elsewhere, as this model is fixed at the stated specifications.

Questions about this item

Which capacity version of the Dr. Battery MPL08318P-30 should I choose for my HP Pavilion 15-AU103NG?

The MPL08318P-30 is offered in a single 4900 mAh / 38 Wh configuration. Match your original battery part number such as 849569-421 or 849569-541 to confirm fit.

What does the 4900 mAh rating mean for daily runtime in my laptop?

At 7.4 V the pack stores roughly 38 Wh. Real-world runtime depends on your Pavilion 15-AU series workload, screen brightness and power settings rather than the mAh figure alone.

What interface does this battery use and what does it limit?

It connects via the proprietary HP Pavilion 15-AU internal battery connector. The 7.4 V output and the smart control chip set the voltage and protection limits for charging and discharge.
