Part of my school music budget is eaten up every year for all the batteries we use in our auditorium in wireless microphones. I am very hopeful a new gizmo called ‘Batteriser’ will change all that. This very cool invention will apparently extend reusable battery life by a boasted 800% and should be available this fall according to a recent article in MacWorld online magazine. Check it out. For approx. $2.50 you can buy the ‘Batteriser’ that will hopefully make a difference.
