Replacement battery for HP Pavilion 15-AU series

This Dr. Battery MPL08318P-03 is a new lithium-polymer pack rated at 7.4 V and 4 900 mAh. It replaces original part numbers such as 849569-541, 849569-542, 849569-543, 849909-850, BP02041XL and BP02XL across a wide range of 15-AU models.

Owners of compatible HP Pavilion 15-AU notebooks

The cell fits machines including the 15-AU103NG, 15-AU105NG, 15-AU106NG, 15-AU107NG, 15-AU108NG, 15-AU109NG, 15-AU111NG, 15-AU123CL, 15-AU134TX, 15-AU136TX, 15-AU137TX, 15-AU144TX, 15-AU145TX, 15-AU146TX, 15-AU147TX, 15-AU148TX and 15-AU149TX. Buyers with different laptop families or other voltage requirements should verify their original battery before ordering.

4 900 mAh capacity and 38 Wh energy

This capacity supplies typical office workloads and media playback for several hours on a full charge. The 7.4 V output matches the original specification, so the pack integrates with the existing power-management system. Heavy gaming or sustained CPU loads will drain the cell more quickly, and users needing longer unplugged runtime should consider a higher-capacity alternative if one exists for their chassis.
