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.

Apple MacBook Pro 17 Battery Specifications:

Technology: Lithium-polymer

Capacity: 68wh

Color: Silver

Weight: 652.05 g

Working Hours: 8 hours

Battery Code: A1189 MA458, MA458 * / A MA458G / A MA458J / A

Compatible Model: Apple MacBook Pro 17 inch Series battery

Warranty: 1 year limited warranty

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.

Rechargeable battery 15-inch MacBook Pro Recall

In August 2006, Apple discovered that some 15-inch MacBook Pro batteries and MacBook Pro 13-inch battery supplied to Apple did not meet our high standards for battery performance. Apple initiated a worldwide battery exchange program for certain rechargeable batteries that were sold for use with 15-inch MacBook Pro computer systems from February 2006 through May 2006. More info here :

Rechargeable battery 15-inch MacBook Pro Customer review :

If you follow the instructions in the manual, and cycle the battery once a week. You may have about 4 to 5 hours life of your MacBook Pro 17inch battery. I tried cycleing the battery and it really works and makes the battery life. But the key is to be carried out once per week.

These Apple A1175 batteries are terrible. I religiously-cycle batteries and I get about 9 months of them before I am up to about 1 to 1.5 hours. Unfortunately, the aftermarket is not much better. I'm glad that Apple is investing in battery technology, because these things are very expensive and suck.

I bought my MacBook Pro in August 2006 and my battery crashed on 15 November. I love my MacBook Pro but the battery is a disaster ...

I think the Apple laptop battery life is pretty good on the MacBook Pro I was in a three hour flight the other day and my Mac battery died shortly before landing. Other PC users around me had to close because of problems with the batteries for 45 minutes. After the flight actually had a contractor ask me what I have equipment and questions about the battery b / c I could not believe it took so long.

But in my opinion, this battery is extremely hot and more than one PC which I've worked on or the PowerBook I had until I upgraded. Therefore, be sure to wear pants or use a pillow when you use your laptop on the lap map!

The design is great for the MacBook Pro and then the battery, I only used a larger fan in the MacBook have to make it this cool thing. I think it is a failure of computer design and less on the battery, but.

9-Cell Primary Dell Inspiron 1545 battery review

The Dell Inspiron 1545 meets two of the most basic laptop requirements: Both its screen and hard drive are large enough to handle the gamut of multimedia tasks. Intel Pentium-branded processor lags behind the mainstream Intel Core 2 Duos, comes with a nice 15.6-inch widescreen, 320GB of storage space, and 4GB of memory. At 5.8 pounds, the Inspiron 1545 rides a fine line between portable mainstream and desktop replacement. Here will write something for Dell inspiron 1545 battery 9Cell primary review.

The Dell inspiron 1545 battery specs :

Technology : 9-cell lithium ion

Capacity : 85Whr

Volt : 11.1V

Manufacturer Part# : RU586

Compatible model : Inspiron 15, Dell Inspiron 1525, Inspiron 1526, Inspiron 1545

This product comes with 1 year limited warranty.

The Dell Inspiron 1545 Battery Over view :

9Cell Inspiron 1545 battery extend your internet business and journey. Inspiron 1545 battey is a safty and fresh battery. It is a little heavy as its 0.43 kg and have a added stick compare to the 6Cell. I think the stick has a 3Cell battery pack. It provides uninterrupted reliable performance you need to get the most out of your system. Inspiron 1545 laptop battery is 12 month quality warraty.

Customer Rview

I have had time to try out my new 9 cell battery on my Inspiron 1545, and it lives up to it's claim of much longer charge time than the standard 6 cell. It's nice to know that I can actually leave the adapter at home and still use my computer for extended periods of time without fear of running out of battery power. A wise purchase for me.

Less than a year, I bought two Dell Inspiron 1545 laptop. I have an update of the 9 cell Dell inspiron 1545 battery. After three months of use, we noticed that no less than an hour burden. Now both teams are getting the message to begin the observation that the life of the battery is low and must be replaced.

I paid for this "best" of the booster battery. But it is a total waste of money. Look carefully at the specifications and details, Dell says the battery. You notice they do not say how long the battery will not hold a charge also say that the life expectancy. I think the battery should last at least a year.

I bought Dell computers in the past and have some sort of problem with either. The two Dell Inspiron is the last time that you buy.

If I buy a new computer, always buy a spare battery just in case. "It was no different when I bought my new Inspiron 1545 just last month. As always, I ordered a spare Dell laptop battery to go with him. Normally, I'm bought the same type that came with the computer, but according to the request a Replacement Battery realized I that while the kit comes with a 6-cell battery, a 9-cell battery is available. The description better battery life promised with 9-cell, and the description was correct. With 6-cell Inspiron 1545 battery, only in a position to want to go around two hours unplugged, but with the 9-cell battery, which go more than four hours was unplugged while on the Internet. you no longer between the classes I need for batteries change, I now use as my primary batteries and took the 6-cell my backup. The extension of the life 9-cell, I do not see me with my 6-cell battery at all.

Sony tips On Using the AC Power Source

The AC adapter, AC/DC adapter or AC/DC converter is a type of power supply - typically those that are embedded in an over-sized AC plug. Other names include plug pack, plug-in adapter, adapter block, domestic mains adapter, or power adapter. Informal terms include wall wart, wall cube and power brick. These are typically packaged with electrical devices that do not contain their own power supply. By separating the power supply from the main body of the electronic device, it can be made more compact and lighter. Any heat dissipated by the power supply is outside the device, so it can run cooler. Using standardized commodity external Sony laptop battery power supplies can simplify regulatory approval for sale in various countries; only the power supply itself needs to be tested for national standards compliance, instead of a whole device.

    See the online Specifications to check the power operation of your model.
  • Do not share the AC outlet with other power-consuming equipment, such as a photocopier or paper shredder.

  • You can purchase a Sony vgp-bps2 power strip with a surge protector. This device prevents damage to your computer caused by sudden power surges, in an electrical storm, for example.

  • Do not pull or place heavy objects on the power cord. Do not use power cords between the Sony vgp-bps5 product and desks or walls or bend or damage it at any time. Damage to the power cord could cause fire or electrical shock.

  • To disconnect the power cord, pull it out by the plug. Never pull the cord itself.

  • Unplug your computer from the AC outlet if you are not planning to use the computer for a long period of time.

  • Make sure that the AC outlet is easily accessible to Sony vgp-bps8.

  • When the AC adapter is not used, unplug it from the AC outlet.

  • Use the AC adapter supplied with your computer or genuine Sony vgp-bps9 products. Do not use any other AC adapter as it may cause a fire or electrical shock.

Toshiba Satellite U505 Notebook Review


The Toshiba Satellite U500 and U505 series notebooks are built with 13 inch display screen, Intel Core 2 Duo Processors, it should leave deep impression to many folks. The U405 is an excellent product in 2008, and now, the new Toshiba pa3399u 1brs laptop Satellite U505 is perfect as well.

Below is the specification for Toshiba Satellite U505:

  1. Processor: Intel Core 2 Duo P7350 (2.0GHz, 1066MHz FSB, 3MB cache)

  2. Memory: 4GB DDR2 SDRAM (800MHz)

  3. Operation System: Windows Vista Home Premium SP1 (64-bit)

  4. Storage: 400GB HDD (5400rpm, SATA)

  5. Screen: 13.3-inch diagonal WXGA (glossy, 1280x800)

  6. Graphics: Integrated Intel Graphics Media Accelerator 4500MHD

  7. Optical drive: Slot-Loading DVD SuperMulti (+/- Double Layer) drive

  8. Wireless: Intel 5100AGN

  9. Dimensions: (W x D x H): 12.5" x 9.08" x 1.16"/1.50"

  10. Weight: 4.75lb (not including weight of AC adapter).

  11. Battery: High Capacity Lithium-Ion Toshiba pa3634u 1brs Battery (12-cell, 92Wh, 8500mAh)

  12. Others: Texture Finish in Luxe Brown Premium

Toshiba pa3534u 1brs U505’s outline is featured with plastic material, Luxe Brown Premium finishing, there are textures around the palmrest and LCD, and it is formed by heavy pressure module. Many other cheap computers which made up of plastic material easy to generate squish sound, but U505 doesn’t.

The brand-new Toshiba pa3420u 1brs Satellite U500 and U505 series notebook feature a portable compact footprint similar to most laptops with a 13.3 inch screen, but we can’t say that this notebook is super protable, actually, it maybe one of the larger 13 inch laptops currently on the market. Toshiba U505 is not only thicker than the Apple's MacBook Air or Lenovo's ThinkPad X301, but also thicker and heavier than the DELL Studio XPS 13 or the 13-inch MacBook Pro.

The U505 screen is WXGA (1080 x 800), CCRL backlight are great. U505 did same with U405 on gloss and matte matching for the screen. So you won’t experience trouble the reflections except you sit under the direct sunlight and the Toshiba pa3450u 1brs screen brightness turns down.

As we know, there are many notebook factories already have begun to improve the display screen to 16:9 aspect ratio as LCD are also 16:9. But on U500 and U505 series, Toshiba still insist on the old 16:10 aspect ratio widescreen display. This character let U505 more seems like square-shaped.

U505 uses flat keys as Toshiba pa3421u 1brs decided to make them seems like an upside down "T" shape, this is not same as the former U405, so the new users have to take few times to familiar with the keys. The keyboard and touchpad backlighting are nice to help you see what you're typing in a dark environment.
