Dr. Battery MPL08318P-11 replacement

The Dr. Battery MPL08318P-11 is a new lithium polymer laptop battery rated at 7.4V and 4900 mAh. It replaces original HP batteries such as BP02XL, BP02041XL, HSTNN-LB7H and HSTNN-UB7B.

Installation and common issues

Installation requires opening the laptop chassis and disconnecting the original battery connector before fitting the replacement. The pack includes a built-in smart control chip that manages charging and provides short-circuit, overheat and overload protection. Buyers must verify the exact laptop model, original battery part number and output voltage before purchase to avoid fitment or detection errors.

Capacity and runtime limits

The battery stores 38 Wh of energy at a nominal 7.7V, delivering 4935 mAh under test conditions. It comfortably powers typical office workloads and web browsing for several hours on a full charge. Runtime shortens under sustained high-load tasks such as video rendering or gaming, and capacity will gradually decline after repeated charge cycles.

Questions about this item

How can I verify the Dr. Battery MPL08318P-11 is working correctly after installation?

After fitting the 4900 mAh 7.4V lithium-polymer pack, the laptop should power on without the charger, show the correct charge percentage in Windows, and run for a period consistent with a 38 Wh capacity.

What comes in the box with the MPL08318P-11 and what must I source separately?

The package contains only the replacement battery itself; no tools, screws, or AC adapter are included, so you will need a suitable screwdriver and your existing charger.

Which capacity version of the Dr. Battery MPL08318P-11 should I choose for my HP Pavilion 15-AU model?

This model is offered in a single 4900 mAh / 38 Wh (7.4V) configuration; match it to your original battery part numbers such as BP02XL, HSTNN-LB7H, or TPN-Q172 to confirm compatibility.
