More Battery Life for Macbook

 

Holy Cow!!! This really works.. I thought for sure I was going to have to buy a new battery for my Macbook.  The laptop is only 2 years old and I was only able to get about 45 minutes before my battery died. Now after applying this calibration in the link below my Macbook goes for about 2.5 hours.
