DESC: The MacBook Pro Battery lasts up to 8 hours on a single charge and can be recharged up to 1000 times — compared with only 200 to 300 times for typical notebooks. To do this, Apple engineers custom-designed lithium-polymer cells to create the largest possible battery, then they went even further: They built the battery right into the computer, eliminating the space-consuming mechanisms and housings that standard removable batteries require. The result is a battery that offers up to 8 hours of wireless productivity on a single charge — all in a notebook that’s less than an inch thin, weighs just 6.6 pounds, and remains the same price as the previous-generation model.
