light weight and long battery life. The charger turns green when the Battery is charged which is good. Used a few times so far, the drill is great. However, here's what's annoying. Once you have the battery in place it will be very difficult to remove. The battery locking mechanism is all plastic and when I press the button on the battery to eject it it doesn't pop out.After struggling with this for 30 minutes I was able to remove it.It seems that when the button is pushed all the way down the internal spring releases the latch doesn't quite pull to remove the battery.Either a bad battery or an unsuccessful design.
