Actually, they are Energizer Lithium Batteries. There's definitely a difference. The main thing has to be the weight. The Lithiums advertise as being one of the lightest on the market. I picked up a 4 pack of Lithiums and Titaniums and the Lithiums were definitely lightter.
The mouse is just about the weight of a regular pro mouse. Adding batteries just makes it heavier. So Apple was smart to put the lightest batteries possible.
And mine lasted 3 months and a week. Amazing.
