Rating : - Extend the useful time on your notebook
My Apple is getting a few years old, now. The length of time the original battery could run the notebook was getting shorter and shorter. Now I have about a two hour charge available: I can use this in my classroom with projector, speakers, bluetooth graphics tablet and smart board attached for a complete class. True, all I did in the past was plug the thing in. But this gives some additional options.
