MacBook, MacBook Air and MacBook Pro computers come with lithium polymer batteries to provide maximum battery life in a compact space. To understand battery technology and battery life, it's good to know common battery terminology:

• Cycle count:Batteries are expected to function for a certain number of cycles. This number represents the sum of total and partial discharge cycles throughout the life of the battery. You can see the cycle count limit for your computer by reviewingDetermine battery cycle count for Mac notebooks.
• Full charge capacity:measured in mAh[milliampere hours], this refers to the amount of power the battery is capable ofcontaining, minus the energy required to shut down the device.This number lowers as the battery becomes depleted with usage and age.
• Remaining charge capacity:this number represents the current amount of power left in the battery as measured in mAh [milliampere hours]. Using the computer when not connected to AC power will cause this number to decrease as power is depleted from the battery.
• Defective:batteries are considered defective when they stop working due to a defect in materials or workmanship, or due to a manufacturing defect. Defective batteries are covered under Apple's one-year limited warranty and extended-service contracts.
• Load:the amount of activity being performed by a task or tasks. Certain power-intensive processes place a heavier load on the battery and result in a greatly reduced runtime per charge.
