Charged batteries are like bacon, you can never have enough
To solve this problem some teachers or IT peeps may consider Oncore’s 6-Bay Battery Charger for Apple notebooks the solution.It’ll charge 3 batteries simultaneously and keep up to six charged and ready for action. Not only will it work with the new Macbooks, it will also work for older iBooks.
Guess that “dog ate my battery” excuse won’t work any more. Curses!
