76% Battery Wear on Alienware M14x R2

I've had my laptop for just 1yr and 8months now and i am shocked when i saw that my battery wear is at a very very high amount


should i be really concerned about this?
i use my laptop mostly plugged in and i rarely use it on battery(like only when the power is out)
how did my battery wear so much when i read that the laptop automatically switches to AC power whenever it is finished charging and there's no need to manuall disable battery charging.. maybe i just had a defect on my battery since i got it?

i also think i should replace my battery,
i was searching through the web and i cant find a somewhat credible source for my battery
i am also living in the philippines so i cant go to stores that some of you would recommend. but i can buy a battery from US and have it shipped to me through a friend
can you guys recommend any sources for a battery?(amazon would be fine)

Thanks!!

 

Buy a new battery. Here's the battery from Dell: http://accessories.ap.dell.com/sna/...&s=dhs&cs=sgdhs1&sku=453-10179&mfgpid=6002012

It's kind of pricey. I suggest looking on eBay or using Google to find other online stores.

 

that is too expensive for me, i found some on amazon, but i am not sure if this is the one i am looking for

Amazon.com: Replacment 14.8v 4200mah/62wh Battery for Dell Alienware M11x M14x R1 R2 R3 8p6x6 P06t Pt6v8 T7yjr 08p6x6: Computers & Accessories

is that the one i need? it looks like the one i have, but it doesnt say M14x R2 on the models it fits

it only includes these models:

Replace part number
PT6V8, 8P6X6, 08P6X6, KR-08P6X6, T7YJR, P06T,
Fit for
Dell Alienware M11X
Dell Alienware M11x R1
Dell Alienware M11x R2
Dell Alienware M11x R3
Dell Alienware M14x

 

Make sure the part numbers match. Don't buy a fake or crap battery.

Also, the Dell battery comes with a 1 year replacement warranty, if that makes any difference.

 

Fake batteries could cost a lot more if they get to damage your PC.
