Apple 17-Inch MacBook Pro battery review

Compare with the MacBook Pro 13 and Pro 15-inch MacBook Pro Macboook 17 has a 40% larger battery (vs 95WH 68WH) 17inch and larger. On MBP17 has a 2.66 or a 2.93 GHz processor, up to 8 GB of RAM and two Nvidia 9400M (integrated) and 9600 (discrete) graphics cards. A 320GB 5400RPM hard drive is standard, but can be converted into a drive with 320 GB 7200 RPM drive or a solid state 128GB/256GB. But at 6.6 pounds, not really so heavy in the hand, as expected. And to 0.98 inches, is only slightly thicker (0.03 inches) than the other two MacBooks.

In fact, the MBP17 battery is enormous. Occupies almost the entire lower half of the bottom of the computer. For the battery as large as possible, Apple has even eliminated the battery removal mechanism. Apple Lithium-polymer pack screws and promises a lifetime of 1000 full load, which means 2000 charge cycles, half or quarter of 4000 charge cycles before battery capacity reduced by 80%.

Apple calls: * Assuming the screen at half brightness, wireless, light browsing, light word processing (for which no Bluetooth, but otherwise a default configuration). Integrated graphics 8 hours, 7 hours with beefy GPU. In fact, the screen just a hair over half brightness, WLAN, Bluetooth off, keypad with backlight, discrete graphics, Web browsing and the occasional Photoshop work, we managed 3 hours of 57 minutes time (the others are the half will light up 4 hours 39 minutes running time). That's almost two hours longer than MBP15 battery* t, and 2 hours and 30 minutes longer than MB13 battery.

17-inch Apple MacBook Probattery reivew of users:

I have two of these batteries and provide power for three or four hours. Performance and durability are achieved according to the instructions in the help section. Apple powerbook g4 battery calibrate once a month for the instructions, and do not let him all the time connected. If you remove the power plug, remove the battery from overcharging. If you do these two things, you will receive a lifetime.

Apple has designed a large battery for 17-inch MacBook Pro keeps, chug 3.5 to 4 hours and far exceeds my old G4 15 "PowerBook battery with double the operating time. I am very impressed. Good job Apple!

After nine months of continuous use my MacBook Pro 17, an unexpected system has recently been completed and is expanding the battery cover and buckling and will not be charged. The life cycle with other rechargeable battery systems I have used seems to be more or less the same.

I had absolutely zero problems with all my purchases from Apple (which is very important.) It seems, however, was my 13-inch MacBook Pro battery shot from the inside, with one side 1.25 "high normal verses 0.5." Of course will not work from within and are exposed to the weather and all internal parts are swollen I bought my MacBook Pro for $ 3514 on my MacBook Pro in 2007 -. without success (my warranty went) through Apple technical service calls, I hope this problem in my Apple Store to be solved. I will be disappointed if I have to pay for a new, after already spending more than $ 10,000 in assets from Apple in the past 10 years.
