Reviews for Rechargeable Battery - 15-inch MacBook Pro

Having used my laptop daily and quite heavily for the past two years, and haven't had a single problem with the battery life. After a little over an hour of watching movies, it's still got over 50% juice left. Full charge capacity is still at 4251 after 200 cycles, battery's at 75% health according to iStat as well. According to Apple's suggested use/charging policies, I've treated it quite poorly as well. Not sure why so many have had problems.

My first battery died shortly before my 1-year warranty had expired. Apple replaced the battery with a new one, but it was reduced to about 2% of its capacity within a few months. Now I'm left with a laptop that will shut down instantly if the power cord is knocked out of place. I spent over $2,000 for a laptop with a battery worth less than the lint in my pocket. Of course, after I had received my second battery my warranty was over and I couldn't get ahold of Apple to see if they would do anything about the second one. My cycle count on the second battery was 57 when it died. I followed all recommended practices for maintaining battery life and even have a new power adapter.

I've had my MacBook Pro for 2 years now with 528 cycles and 52% left. Far superior to other products I've owned!

I have gone through 2 batteries, I gave this a 3 star because of apple replacing both batteries.

Tip genius gave me
run it like a lap top, put it through charge cycles

right now when i run it like a desktop i take out the battery, it runs as long as you have it plugged in

I am not sure why so many people are complaining about this battery. I had mine for three years and it worked great. Then, I installed Windows 7 on my Macbook Pro, and that, for some unknown reason, fried the battery. Afterwards, I could only get 30 minutes out of it (before I played around with Windows 7, the battery had 1.5 hours of life in it). So a word of caution... Don't install Windows on your Mac notebooks!

Even with following the proper charging cycles, plan on this battery having a 1 hour lifespan within the first 6 months of use. Sometimes, even when the battery icon says you have another hour left, the computer will completely shut down mid-use and will take 30 minutes of being plugged in before the battery charges enough for it to turn on. This is extremely stressful when you're working on deadlines and don't have 30 minutes to wait for your computer to charge. In my opinion, Apple should recall all of their macbook pro batteries, or just replace them for free.

Disappointed with the battery life. After a year and a half mine was toast. I even bought the apple care plan and they wouldn't replace it. Talk about frustrating. Great computer, but when you don't take care of the people who are trying to take care of the merchandise bought from you. It really hurts the overall product.

I'm replacing the 2nd battery on this laptop. The latest lasted 21 cycles. It's outside the 90 day warranty so I'm out another $130. Calibrating did no good, all of the resets did no good. You can't fix garbage. Apple should be ashamed of themselves.

Yeah, there is a problem with these batteries. I've had 2 replaced under warranty in the last 18 months but now the warranty is expired and I'll have to shell out the cash or always be plugged in. Your credit card issuer MAY offer to extend the 12 month warranty if you purchase a NEW battery. Thats my plan, at least I know I'm good for another 24 months for $130. Not the best, but gotta make it work!
Cycling the battery will help make it last, try to do that.

This battery obviously has a design flaw. Too many of them develop a problem where they just stop putting out power even though they have a substantial amount of charge left. My original was replaced under warranty and now the replacement has developed the same problem. It's worse than a worn out battery that won't hold much of a charge because with those you get a warning before they die. With these the computer just shuts off without warning.

Bad Apple. Bad, bad Apple. Could be worse, though. Could be one of those models where the battery is internal.
