Replacement battery for HP Pavilion 15-AU series

This Dr. Battery unit replaces the original power cell in numerous HP Pavilion 15-AU models including the 15-AU150TX, 15-AU160TX and 15-AU163TX. It matches the OEM form factor and connector so it fits directly into the battery bay without modification.

Built-in smart control chip and safety protections

The integrated chip manages charging current to reduce power consumption and extend discharge time. It also provides short-circuit, overheat and overload safeguards that protect both the battery and the laptop during daily use.

4900 mAh capacity at 7.4 V delivering 38 Wh

The lithium-polymer pack stores 4900 milliampere-hours at 7.4 volts for a total energy rating of 38 watt-hours. This capacity supports typical office and web-browsing workloads for several hours, while intensive tasks such as gaming or video rendering will deplete the charge more quickly.

Questions about this item

Does the MPL08318P-04 need any calibration cycles after installation?

No calibration is required; the built-in smart control chip manages charging and discharge automatically from first use.

What limits runtime during a full day of continuous work?

The 4900 mAh / 38 Wh capacity sets the energy ceiling; sustained load will drain the pack until it reaches the chip's low-voltage cutoff.

How much heat does the battery generate when the laptop runs all day?

Lithium-polymer cells and the protection circuit keep heat low; normal operation stays within the 7.4 V design envelope without active cooling.
