I was skeptical that this battery would be good because of the low price, but I decided to give it a try, also because of the low price. It arrived quickly and was well packaged. It had less than a full charge when I first installed it so I waited until it was fully charged (didn't take long) before using it. It lasted about 3 hours before the charge level was low enough that I thought about putting it on the charger again. I thought this was very good for an older laptop that has a large screen. It has been the same every time I have used it. I am very pleased with this battery.
