Replacement battery for HP Pavilion 15-AU series
This Dr. Battery MPL08318P-23 unit replaces the original battery in numerous HP Pavilion 15-AU models including 15-AU178TX and 15-AU502TX. It uses lithium-polymer cells rated at 7.4 V and 4900 mAh to restore mobile power for owners of compatible notebooks. The pack is supplied new and carries a one-year manufacturer warranty.
Straightforward swap with built-in safeguards
Installation follows the standard battery-bay procedure: remove the old pack, align the connector, and secure the replacement. A smart control chip manages charging current and provides short-circuit, overheat and overload protection to reduce the risk of damage during daily use. Verifying the original part number such as 849569-421 or 849909-850 before fitting avoids the most common mismatch.
38 Wh capacity for typical workloads
The 4900 mAh cell delivers 38 Wh, which comfortably handles web browsing, document editing and video playback on supported Pavilion 15-AU chassis. Runtime drops noticeably under sustained high-load tasks such as gaming or rendering, so users who need all-day autonomy away from mains power should plan for a recharge or a spare pack.
