Replacement for HP Pavilion 15-AU series

This new Dr. Battery lithium-polymer pack replaces the original battery in compatible HP Pavilion 15-AU models such as the 15-AU178TX, 15-AU502TX and 15-AU620TX. It matches the OEM voltage of 7.4V and fits the same battery bay without modification. The unit is ready to install on supported part numbers including HSTNN-UB7B, TPN-Q172 and TPN-Q175.

Upgrade from a worn or failed original pack

When the factory battery no longer holds a useful charge or shuts down under load, this 4900 mAh unit restores the laptop's mobile runtime to its original level. The jump is worth it if the existing pack shows swelling, rapid percentage drops or cannot sustain the system away from mains power. It does not increase capacity beyond the stock 38 Wh rating, so buyers who want more storage than the original design cannot gain it here.

Capacity and headroom for daily mobility

The 4900 mAh cell delivers 38 Wh at 7.4V, supplying enough energy for typical office work, web browsing and media playback on a single charge. The built-in smart control chip manages charging, short-circuit, overheat and overload protection to keep discharge stable. Runtime shortens under heavy CPU or GPU load, during gaming or when driving external displays, which is the point where the pack runs out of headroom.

Questions about this item

Does the 7.4V MPL08318P-17 battery fit the HP Pavilion 15-AU178TX chassis without modification?

The battery is built as a direct replacement for the original 849569-421 pack used in the 15-AU178TX and matches the laptop's internal mounting points.

What is the correct sequence for installing the 4900 mAh lithium-polymer pack in a Pavilion 15-AU series notebook?

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

When will the 38 Wh Dr. Battery cell need replacement under normal daily charging?

The one-year manufacturer warranty covers defects; after that period, monitor runtime decline to decide when a fresh pack is required.
