Dr. Battery MPL08318P-28 laptop battery 4900 mAh 7.4V

Replacement Battery for HP Pavilion 15-AU Series

This lithium-polymer battery replaces original HP units in compatible Pavilion 15-AU models including the 15-AU150TX and 15-AU160TX variants. It delivers 4900 mAh capacity at 7.4V to restore mobile runtime for users whose original packs no longer hold sufficient charge. The pack suits owners of listed part numbers such as HSTNN-UB7B, 849569-421, 849569-541 and 849569-542 who need a direct swap without adapter changes. Buyers with other laptop families or different voltage requirements cannot use this unit.

Thermals and Power Behaviour

The 38 Wh cell operates at the nominal 7.4V and 7.7V device voltage specified for the target platform, drawing power within the laptop's original charge circuitry limits. A built-in smart control chip manages charge current to reduce heat during replenishment and extends discharge time under normal workloads. Protection circuits guard against short circuit, overheat and overload conditions so the pack remains stable during daily use. No external cooling or special power settings are required beyond the host laptop's standard management.

Build and Connector Details

The black lithium-polymer enclosure matches the form factor expected by the compatible Pavilion chassis, allowing the battery to seat securely in the original bay. Connector pin-out aligns with HP part numbers HSTNN-UB7B, TPN-Q172 and TPN-Q175 so the ribbon engages without forcing or adaptation. A one-year manufacturer warranty covers defects in materials or workmanship. Users whose machines fall outside the listed model range or who need higher capacity than 4900 mAh should verify specifications before ordering.
