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

I can't believe that my Macbook battery barely lasted 2 years, now, I need to have my Macbook plugged in all the time, it won't even last a minute without it. I am thinking if it is worth investing another 130$ on this, which may not even last a year or just buy an iPad and keep the Macbook plugged in..

I am not too impressed with the quality of battery life..

Having bought the late-2008 unibody MacBook in April 2009, I have used this laptop extensively, with the same battery.

Battery Information:

Cycle count: 604

I still get about 2 hours (at 50% brightness) fully charged. I"m in the market for a new battery, but the battery I have now is still chugging through :D

Full charge capacity (mAh): 270
Health Information:

The battery all of the sudden died on my after 400 cycles, and it doesnt hold its charge longer than 2 minutes.

Current Battery Capacity: 2153 mAh
Original Battery Capacity: 4100 mAh
Battery-Loadcycles: 350
Age of Mac: 23 months

In about a month, my battery capacity has plummeted from 75-80% to 52%! This is a rapid deteriation, which I wasn't expecting, as I take good care of my battery. I can't even calibrate the battery properly now, due to the ever-increasingly decine in battery capacity - the battery doesn't know when to reserve charge for when it needs to go into sleep mode! This means that my macbook will suddenly, without warning, shut down, and due to Pages not having a recovery function, I have lost several important documents.

I do not have the money avaliable to suddenly shell out £100. Their needs to be a price cut, or a new battery developed. It is ridiculous that the mac issued less than a year after mine has a 5-7 hour charge and a lengthy shelf life, and mine, which i purchased for a similar price, has a 1-2 hour charge after less than 2 years of use.

i cant complain about the performance of my computer... apple has very good products... now i can agree with others that the battery dies all too quickly... but in my case it happened because more than often i would just leave my comp on for days even weeks and it would die on its own... thus came the problem where it just started dying all to quick.. now im lucky if it last a minute unplugged... its not just apple computers that do this, every other comp without the proper care will die, and if u leave your laptop on and plugged all the time it will drain your battery even faster, and your computer wont have any other choice but to rely on the power plug to stay alive... word of advice once you are done using your computer just shut it down yourself.. if you are not lookin for an extra battery this will save u money...

Not much to add to what others have said about the poor performance of this battery. I never unplugged my laptop much and after only 197 cycles by battery is defunct. Apple Store was no help. Now out of warranty. Upset.

I have owned a MacBook 13" for just over 2 years. The battery can't hold a charge anymore. Only 266 cycles. Once it gets to 25-30% remaining charge - just goes black! Not good enough for any product but especially Apple!

Dunno what's going on, but this battery just doesn't cut it anymore. I've had this second generation, or first, aluminum laptop for little under a year and now the battery is acting up. The battery can't last no longer than 45 minutes without dying. As I type this, the battery went down from 21% to 14%, which was about five minutes. I like this brand, but this is ridiculous. I don't want to have to switch over to Dell or Sony.

I've had my MacBook for two years. I noticed it was holding a charge for significantly less time about 6 months after I purchased it, and it has become progressively worse. now it wont hold a charge at all. I was shocked to see so many others having the same problem. Interestingly, I can still get a half hour out of my 11 year old power book when it is fully charged. Do I need to buy a new battery every year or two?

I came to this site to check the prices for this battery to replace my current one, and not only was I surprised to find so many negative reviews, but also disappointed as i've had the same experiences, which you would not expect seeing as this was an Apple branded product. Two years is INDEED the magic number, I've had my MacBook since 2008 and it continues to work fine, but the battery itself will only last about 30 - 40 mins on a full charge. If I dim the screen to about 25% (which barely makes you able to see anything depending on the lighting) then you MAY squeeze out more. $129 is honestly laughable for this product.
