What's the difference between 45Wh and 54Wh battery?
Hi,
I was looking for a new battery for my MacBook Aluminum Unibody (Late 2008) and found that there are 45Wh and 54Wh battery. So what's the difference between 45Wh and 54Wh one at the same capacity? Will the 54Wh one offer a longer usage-time?
Thanks,
Nathan
