Direct replacement for Alienware 13 R3
This lithium-ion battery delivers 76 Wh at 15.8 V and matches the original TDW5P form factor. It fits the Alienware 13 R3 and the extensive model list including ALW13C, ALW13CR and D-series variants. The pack ships new in black with a 12-month warranty.
Capacity and daily headroom
At 76 Wh the cell provides a full day of typical office work or several hours of gaming on a single charge. Runtime drops under sustained GPU load or high screen brightness, so keep the charger handy for long sessions.
Upgrade from worn originals
Swapping a depleted factory pack restores original run-time and removes the need to stay tethered to an outlet. The change is worthwhile when the old battery holds less than half its design capacity or shows swelling.

Questions about this item
Will the 15.8 V 76 Wh TDW5P battery fit my Alienware 13 R3 without changing the original charger?
Yes, the TDW5P matches the original 15.8 V specification and replaces part numbers 04RRR3, 0V9XD7, 4RRR3, JFWX7, P81G and 41CP7/73/64, so your existing Alienware charger works unchanged.
How can I verify the new battery is recognised and charging correctly after installation?
Power on the laptop, open Windows Battery Report or the Alienware Command Center, and confirm the design capacity shows 76 Wh at 15.8 V with a charging status while the AC adapter is connected.
Does the package include only the battery or are screws and tools supplied as well?
The box contains 1x TDW5P battery only; mounting screws and any opening tools must be sourced separately.
