    A: Firstly, maybe you have choosed a wrong charger or electro circuit which can not fit your Aspire 5820T battery.

Let me start out by saying that I was quite skeptical of buying a battery online for half the price that Acer offers them at, but being the extremely broke college student that I am, I really didn't have much of a choice. Let me tell you that so far, this product is great. (its only been a few days, but all seems well) Fits perfectly into my laptop, and holds a charge for over 3 hrs while surfing the internet and through constant use. I would suggest your site to anyone and am extremely satisfied.


This was a great product! the battery fits perfectly into my laptop.The battery definitely lasts a whole lot longer than the manufacturer battery did. I am extrememly satisfied and would definitely reccommend and buy again from your company.
