DeepSleep will allow your Mac laptop or desktop to sleep without using any power or drain the batteries. It saves everything to disk and stops using power completely. When you wake up your machines by pressing the power button, DeepSleep will restore everything and wake up just like you left it. It takes a little longer than normal sleep but it is a great battery saver when you know you won't be using the computer for a while. Give it a try, you will love the convenience and the extra battery life!

Requirements:
OS X 10.9+
