The longest-lasting Mac notebook battery ever.
The battery in the new 17-inch MacBook Pro lasts up to 8 hours on a single charge1 and can be recharged up to 1000 times2 — 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’s 40 percent bigger than the previous generation and 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,3 and remains the same price as the previous-generation model.

But building a battery that lasts up to 8 hours is only part of the story. Giving it a lifespan of up to 1000 recharges required breakthroughs in battery technology. Apple electro-chemists developed advanced chemistry that maintains the battery’s charging capabilities longer than ever. And while most notebooks wear down their batteries by charging them at a constant rate, the 17-inch MacBook Pro takes a different approach. Using an Apple-developed technology called Adaptive Charging, a microchip on the battery constantly communicates with the computer to determine the optimal way to charge its cells, adjusting the current up and down depending on a variety of conditions. Combined, these advancements offer a dramatic improvement in battery lifespan: more than three times the lifespan of typical notebook batteries — up to five years.

With the high-resolution LED-backlit widescreen display on the 17-inch MacBook Pro, you get desktop-quality color in an Apple notebook for the first time. The moment you open your MacBook Pro, you’re greeted instantly by full, corner-to-corner screen brightness. The 1920-by-1200-pixel resolution (133 pixels per inch) means you can view more palettes and windows or watch HD video in its native 1920-by-1080 resolution. Perfect whether you’re working in the studio or out in the field, the display offers a 60 percent greater color gamut than previous generations for richer, more vibrant colors and a 700:1 contrast ratio that makes whites brighter and blacks blacker. In addition, the seamless glass enclosure makes the display stronger and more durable. Because it’s power efficient and the glass is mercury- and arsenic-free, it’s greener than ever. And now you can choose a standard glossy display or an optional antiglare display, depending on your needs.
