Compatible Dell Alienware 13 R3 replacement

This Dr. Battery MPL05354P-09 is a new lithium-polymer pack built to match OEM specifications for several Dell Alienware 13 R3 sub-models. It delivers 4802 mAh at 15.2 V for 76 Wh of capacity. The black unit suits owners of the listed ALW13C variants who need a direct swap for the original battery.

Straightforward swap with built-in safeguards

Installation follows the normal laptop battery procedure: remove the bottom cover, disconnect the old pack and connect the new one using the original connector. A smart control chip provides short-circuit, overheat and overload protection while enabling quicker charging and longer discharge time. The main risk is ordering the wrong variant, so verify your laptop model and original battery part number before purchase.

76 Wh capacity for typical daily workloads

The 4802 mAh cell comfortably powers general productivity, web browsing and media playback on the supported 13-inch Alienware chassis. Heavy GPU or CPU loads will drain the pack faster, reducing runtime compared to light use. Users who need all-day operation away from mains power without recharging may find the capacity limiting.

Questions about this item

How can I confirm the 15.2 V 76 Wh battery is charging correctly after installing it in my Dell Alienware 13 R3?

The built-in smart control chip manages charging; once installed, the laptop's battery indicator should show the 4802 mAh capacity filling normally and the system should run without sudden shutdowns.

What comes in the box with the MPL05354P-09 and do I need any extra tools to fit it?

The package contains the replacement battery only; no screwdrivers or opening tools are included, so you will need a suitable Phillips driver to remove the bottom cover of the Alienware 13.

Which Dell Alienware 13 sub-models does the MPL05354P-09 replace and how do I pick the right one?

It replaces batteries 4RRR3, JFWX7, P81G, P81G001 and TDW5P in Alienware 13 R3 units labelled ALW13C-D1738, D2508, D2728, D2738 or D2838; match the original battery part number on your old pack to this list.
