I bought this mid December for my ASUS UL50 and it worked well for the first few weeks. It arrived quickly and worked well for the first few weeks. Yesterday, about one month after using it for the first time, it failed to charge correctly. The recharging lights on my computer started blinking green- meaning it was fully charged to orange-meaning low charge. Later when I was using my laptop, the icon on the bottom right showed more than half of the power remaining but it went dead and suddenly shut off.
I thought it was maybe just a computer failure so I installed the OEM battery and it started charging right away. I tried charging this replacement battery but the same problem - lights started blinking. I don't know what's wrong with it but I'm hoping the manufacturer will exchange this defective one for another one that will hold a charge.
I bought this battery thinking that it will not worth to me but after using it couple of days I found that Oh my GOD thats gr8. It is producing more power than my previous one. I am very happy with this purchase.
Great battery at great price. The battery doing well as per its title..........
The battery is the same mAh as the factory battery, but for the price difference I can get two of these and still save money. Awesome for the price... and I get something like 3 hours on one charge.this battery is rock ..i have more lifetime on my dell laptop
