Dr. Battery MPL08318P-15 replacement

This lithium-polymer battery replaces the original pack in HP Pavilion 15-AU series laptops. It matches the OEM voltage of 7.4 V and fits models such as 15-AU103NG through 15-AU149TX. The unit is new and includes a smart control chip for charge management.

4900 mAh capacity and 38 Wh energy

The cell stores 4900 mAh, delivering 38 Wh for typical office and media tasks. It supports several hours of unplugged use on a single charge. Runtime decreases under heavy CPU or GPU load, and the pack will eventually require recharging.

Smart chip protections and thermal limits

Built-in circuitry guards against short circuit, overheat and overload during normal operation. The polymer chemistry runs cooler than older cylindrical cells at similar loads. Sustained high discharge will raise temperature and trigger the overheat protection.

Questions about this item

Will this 7.4 V 4900 mAh lithium-polymer pack fit my HP Pavilion 15-AU144TX alongside the original charger and motherboard?

Yes — the battery is listed as compatible with the 15-AU144TX and other 15-AU models, and it matches the HSTNN-LB7H / HSTNN-UB7B part numbers used in those chassis.

How can I confirm the MPL08318P-15 is charging and reporting capacity correctly after installation?

The built-in smart control chip communicates with the laptop’s power management; you should see the 7.4 V / 4900 mAh rating appear in the OS battery meter and the charge cycle complete without error codes.

Does the box include mounting screws or tools, or must I source them separately?

The package contains only the replacement battery; any screws, brackets or opening tools required for your specific 15-AU series chassis are not included and must be sourced separately.
