This pack replaces factory batteries that no longer hold a useful charge in the listed Alienware models and the P31E, P69F and ALW17C series.

Questions about this item

How do I install the 99Wh 11.4V Li-polymer battery in my Alienware 15 R3, and what step is often missed?

Power off the laptop, disconnect the AC adapter, remove the base screws, detach the old battery connector before lifting it out, then connect the new battery firmly before reassembling; the step most often missed is unplugging the old battery connector first.

What maintenance or replacement will this 99Wh battery need over its lifespan?

The battery is rated for up to 500 recharge cycles; after that capacity will drop noticeably and a replacement will be required.

What limit appears first during sustained heavy use of this 11.4V battery?

Temperature control protection activates if the pack overheats during prolonged high-load operation, throttling output until the cells cool.
