I have ordered it for my friend's laptop and fortunately it did fit. Customer service was very friendly and might be a great battery, but we cannot tell now.
With moderate usage, including surfing the Web with WiFi and a little YouTube video, plus sometimes some music in iTunes, this battery lasts about 4 hours! Incredible for the price.
I am glad to report that I have regularly gotten around 6 hours of usage on the battery power alone, which is perfect for what I need to use my computer for. I recommend this battery as it is performing very well for me right now, and has been for the last couple of months
