Dr. Battery MPL08318P-20 replacement

This new lithium-polymer battery replaces original HP units for the Pavilion 15-AU series. It fits models including 15-AU109NG, 15-AU111NG, 15-AU123CL and 15-AU134TX among others listed. The black pack delivers 4900 mAh at 7.4 V to restore mobile runtime.

Fits HP Pavilion 15-AU chassis

Installation uses the existing battery bay and connector without extra cables or tools. The integrated smart control chip manages charging cycles and provides short-circuit, overheat and overload protection. Swapping the old pack frees the notebook from wall power for daily tasks.

4900 mAh capacity and 38 Wh energy

The 7.4 V cell supplies 4935 mAh rated capacity for typical office workloads and media playback. Heavy multi-core processing or high screen brightness will drain the pack faster. Users needing all-day autonomy away from mains should carry a spare or USB-C power bank.
