Alienware 14 warranty covers battery?

I got my Alienware 14 seven months ago and since then I've been using it like a desktop rather than a laptop (Always plugged in with the AC adapter), I did this because I read that the new alienware 14 had lithium battery and the battery wouldn't have any problems but now I started getting the classic "Plugged In not charging", some weeks ago it charged until 77% now it charges up to 64% and keeps decreasing daily. I already updated my Bios and the drivers, took the battery down and connected the AC adapter and deleted the battery drivers and re installed them but nothing seemed to work. I would want to know if the default warranty covers the battery so I could get a new one, and how could I get the battery if I don't live in the united states but I am going to Los angeles soon for holiday. If the warranty doesn't cover it where can I buy a new battery for Alienware 14 (2013 model) preferably not online.
Thanks for the help!

 

I believe the battery has its own warranty. It should come with a 1 year warranty. The policy recently changed.

If you are within that one year of ownership, call Alienware Technical Support ASAP.

 

Dell has international warranty, so you need not visit USA to claim warranty, just contact your local Dell support.
