Great battery (and don't forget to calibrate)
On "Better Battery Life" I routinely get close to five hours of battery life (while using it)!
New Apple batteries, those inclu On "Better Battery Life" I routinely get close to five hours of battery life (while using it)!
New Apple batteries, those included with a machine and those bought separately, arrive partially charged and need to be calibrated. This procedure provides a baseline for the processor built into the battery, so the processor can effectively regulate power consumption.

Expensive but better than the competition
Realistically, you are probably going to get 5 hours at the most with this battery. That said, stick with the original. I bought a Realistically, you are probably going to get 5 hours at the most with this battery. That said, stick with the original. I bought a replacement battery for around $30 online. I thought I was getting a great deal. Three months later, the battery quickly developed gaps so I would get sudden shutdowns...those can easlily corrupt OSX and prevent startup.
