Couple years back, I had a battery bulge issue for my Alienware 17 R4 that was bought in November 2017. Warranty expired February 2019. I had it replaced by Alienware support back then (January 2020). They charged me with full battery price back then. Now am facing the issue again with my replaced battery. It has started to swollen now. These last two years I had bare minimal usage for my Alienware as I have been using my office laptop the most and not even played a single game. Last time, the support team told me that I would have done something wrong for this battery swollen issue but this time I am pretty sure that they are wrong and Alienware have the worst battery / worst QC for the battery pack.
