4. Under Battery Information, you can find the current capacity (fully charged) and also the original capacity for the battery - the cycle count shows how many times the battery has undergone an AC charge to full - Mac batteries typically have about a 1000 cycles - eventually they will run down more quickly - time to replace them when that gets too annoying.

Replacement batteries for many Macs can be ordered at OWC
