FastMac 17" MBP battery
Upgrade specialist FastMac has announced a new upgraded notebook battery, designed specifically for the 17-inch MacBook Pro. By swapping it with the default unit, owners are said to gain extended battery life, over and above the 5.75 hours promised by Apple. Along those lines, the FastMac battery is rated at 71Wh, surpassing Apple's 68Wh figure. Both batteries, however, use lithium-polymer cells, and have LED lights to indicate charge status. The new FastMac model should ship within 10 days, and can be pre-ordered now for $100; this is said to be $30 cheaper than a replacement from Apple.
