Extended Capacity 74 Watt Hour Battery for MacBook Pro 17"
MacWizards has teamed up with one of the most experienced battery producers in the world to provide a reliable and inexpensive upgade or second battery for your Macintosh computer. This battery is a Li-Polymer 10.8 volt 6800 mAmp hour battery designed for the all 17" MacBook Pro computers with removable batteries. It features a 74 Watt Hour extended capacity.
Note: The MacBook Pro is the silver colored laptop with a magnetic power connector, if you have a black or white computer you may have a MacBook but it is not a MacBook Pro. Also, Apple has recently released a new MacBook Pro with a non-removeable battery.
With a 8% greater capacity than the original Apple battery, this battery meets or exceeds all Apple specs for the 17" MacBook Pro with removeable battery with a fit and finish that compliments your laptop. Featuring integrated charge level display LEDs and integrated circuitry to report battery level to the MacOS (allowing you to observe battery level from the menu bar in your computer desktop).
Macintosh laptop computer batteries have a lifetime of roughly 500 to 800 recharges. If you use your computer daily, that means you can expect the battery to last about 15 months to two years (although it will experience reduced lifetime before then and you may choose to replace it annually). When your battery starts to go, the usuable capacity of the battery will reduce slowly at first and more rapidly as the battery nears life end.
Per Apple's recommendation, it's a good idea to fully drain and recharge your battery at least once a month (more often is better) for optimal battery life. This also recalibrates your battery to insure that the time per charge estimate provided by the MacOS continues to be reliable.
