Off-the-shelf lithium-ion cells come in fixed, cylindrical shapes. The 13-inch MacBook Pro is powered by custom-made, ultrathin lithium-polymer batteries.
The standard aluminum electro-static trackpad has been replaced with a new glass Multi-Touch trackpad, which provides 40 percent more tracking area than before. Use two fingers to scroll up and down a page. Pinch to zoom in and out. Rotate an image with your fingertips. Swipe with three fingers to flip through your photo libraries. Swipe with four fingers to show your desktop, view all open windows, or switch applications. The entire trackpad surface is also a button, allowing you to both track and click virtually anywhere on the trackpad. And you can easily enable multiple virtual buttons in software, such as right-clicking.

The keyboard has also been improved, with the rigid aluminum keyboard webbing cut precisely to hold the keys, which are curved to perfectly fit fingers. And it's illuminated, so when you're in low-light settings, such as airplanes or conference rooms, you can always see what you're typing.

The 13-inch display is made of edge-to-edge, uninterrupted glass for a smooth, seamless surface and features LED backlighting for brilliant instant-on performance that uses up to 30 percent less energy than its predecessor. The ultra-thin displays provide crisp images and vivid colors which are ideal for viewing photos and movies

Long-Lasting Battery
The 13-inch MacBook Pro now includes a newly engineered lithium-polymer battery that that lasts up to 7 hours on a single charge thanks to advanced chemistry, intelligent monitoring of the system and battery, and Adaptive Charging technology. The battery is built right into the computer, eliminating the space-consuming mechanisms and housings that standard removable batteries require. This non-removable battery also provides a longer battery lifespan of up to 1000 recharges--meaning fewer depleted batteries and less waste, which is better for the environment.

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 13-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.

Intel Core 2 Duo Processor
Experience improved energy efficiency, expanded wireless connectivity, and amazing battery life with the 2.26 GHz Intel Core 2 Duo processor, which has a super-fast 1066 MHz front-side bus (FSB), and an large 3 MB L2 cache. (An L2, or secondary, cache temporarily stores data; and a larger L2 cache can help speed up your system's performance. The FSB carries data between the CPU and RAM, and a faster front-side bus will deliver better overall performance.)

The hafnium-infused circuitry--which reduces electrical current leakage in transistors--conserves even more energy, giving you more time away from the wall outlet. With 3 MB of shared L2 cache, data and instructions can be kept close to the two processor cores, greatly increasing performance and allowing the entire system to work more efficiently. And, because the processor cores share the L2 cache, either can use the entire amount if the other happens to be idle.
