Dr. Battery MPL08318P-08 replacement

This new lithium polymer battery replaces the original unit in HP Pavilion 15-AU series laptops. It delivers 4900 mAh at 7.4 V and matches the 38 Wh energy rating. The pack is aimed at owners of the listed models who need a direct drop-in replacement.

Thermals and power behaviour

The built-in smart control chip manages charging current to reduce heat during recharge cycles. Overheat, short-circuit and overload protections shut the pack down before temperatures reach unsafe levels. Normal operation stays within the original thermal envelope of the laptop chassis.

Smart chip and safety features

The onboard controller enables quicker charging and lower self-discharge compared with unmanaged cells. Integrated safeguards prevent damage from accidental short circuits or sustained overloads. A one-year manufacturer warranty covers defects in materials and workmanship.

Questions about this item

How do I install the MPL08318P-08 battery in my HP Pavilion 15-AU109NG and what step is often missed?

Power off the laptop and disconnect the AC adapter. Remove the base screws, lift the bottom cover, unplug the old battery connector, fit the new 7.4 V pack, reconnect the cable, replace the cover and screws, then charge fully before first use.

What maintenance or replacement will the 4900 mAh lithium polymer pack need later?

The cells lose capacity over repeated charge cycles; when run time drops below what you need, replace the pack with another MPL08318P-08 or compatible 7.4 V unit.

What limit appears first during sustained use of this 38 Wh battery?

The 4900 mAh capacity sets the runtime ceiling; under continuous load the pack will discharge until the built-in protection triggers a shutdown to prevent over-discharge.
