Questions about this item

Does the 7.4 V lithium-polymer cell run hot or draw extra power during long sessions?

The 7.4 V lithium-polymer pack is built to OEM specification with a smart control chip that manages charging current and discharge rate, so heat and power draw stay within the original design limits for the HP Pavilion 15-AU series.

What must I already own to install the MPL08318P-29?

You need a compatible HP Pavilion 15-AU model such as the 15-AU103NG, 15-AU105NG, 15-AU106NG, 15-AU107NG, 15-AU108NG or 15-AU109NG, plus a small Phillips screwdriver to open the battery bay.

Will this 4900 mAh pack work beside the original 7.7 V 4935 mAh battery in the same laptop?

The replacement matches the original 7.7 V 38 Wh rating and fits the same HP Pavilion 15-AU chassis, so it behaves identically to the factory cell without any BIOS or hardware changes.
