Reviews for Rechargeable Battery - 13-inch MacBook (aluminum)

After 39 months and 1373 cycles, my original battery still has 74% of the original capacity. I'm impressed.

The battery worked fine for about a year. But it started swelling after that. I was ready to pay for a replacement, but Apple does not give warranty against swelling. So you are on your own if the new battery also swells. Moreover, the Apple rep also said that it's "normal" for a battery to swell.

I've had this battery for almost 3 years, and as you can see above, over 1k cycles. I'm going to have to replace now, but based on the fact that it lasted this long, I'm not at all reticent to pay the $130.

Honestly, the MacBook batteries are generally very well built. Mine has lasted me 3 years, I'm on 784 cycles and I can still get a solid 3 hours on it! Purchasing a second battery will only give me extra hours on my laptops life :)

I have also found the battery in my Macbook to be less than great. But that is apparently a known trade-off on Apple's part. Seeing some of the reviews here, it seems clear that some people would benefit from "recalibrating" their batter from time to time. Here's how to do it (from Apple's support site):


PowerBook G4 (15-inch Double-Layer SD), MacBook (all models), MacBook Pro (all models), and MacBook Pro (17-inch) (all models)

The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) and any model of MacBook or MacBook Pro has been updated because of a new battery released with this computer. With these computers, follow these steps to calibrate your battery:

Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.

Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.

Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.

At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.

Turn off the computer or allow it to sleep for five hours or more.

Connect the power adapter and leave it connected until the battery is fully charged again.

Tip: When the battery reaches "empty", the computer is forced into sleep mode. The battery actually keeps back a reserve beyond "empty", to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, with the safe sleep function introduced in the PowerBook G4 (15-inch Double-Layer SD) computers, the computer's memory contents have been saved to the hard drive. When power is restored, the computer returns itself to its pre-sleep state using the safe sleep image on the hard drive.

I have owned my 13-inch Aluminum MacBook for a little over two years now. The original battery is still installed in my MacBook. Below are the statistics from System Profiler for my particular battery:

Charge remaining (mAh): 3923
Fully charged: Yes
Charging: No
Full charge capacity (mAh): 3935
Health Information:
Cycle count: 420
Condition: Normal

The MacBook's battery life is still 4-5 hours with about a 1/4 screen brightness, and surfing the internet. I think this is quite amazing for a two year old computer! I love my Aluminum MacBook!

I bought my macbook pro a year and 1/2 ago and my battery is at 28% health. now i have to get it serviced and that battery probably wont be good either. everything about the macbook pro is great and useful except the horrible battery. I only gave it 2 stars because the macbook pro is such a great computer.

Im a big apple fan and I really enjoy all their products, expect this battery! I got the Macbook because of everyones review on how great they are and how they never seem to have any problems, and I never have except for this battery. It lasted me just a year during which time it would only give me about 1.5 hours of cordless use. After the one year period I have used it - it just completely died out on me. Im sorry, I really don't think it is worth spending $130 for another try at this batter.
