Reviews for Rechargeable Battery - 17-inch MacBook Pro

My battery expanded, unfortunately. If you go to "about this Mac' (in your menu) > More Info > Power > Full charge capacity. on the 17 inch it should read about 2205. Then check Cycle Count. My number is at 578. The problem is that the batteries are only 'good' until about 300, after that they start doing weird things, like making your laptop shut down while it is plugged into the charger, etc. You just need to purchase a new battery. Also, they tend to get hotter faster the older they are, which explains the expansion. Hope this helps. I am a bit disappointed, but I guess it just happens.

My macbook pro was purchased Sept 06, and I was using the original battery up until today (Oct 09)! My laptop isn't used heavily but i still thought this was pretty impressive when compared to some of the reviews I read on here.

However, for the past few months my laptop has been switching off unexpectedly. At first it started doing this at around 50% remaining battery level, but as weeks went by this gradually rose until eventually I was afraid to even use it for a few minutes without the power cord.

Then about 2 weeks ago I noticed my laptop began to wobble on a flat surface. Soon I realized that it was the casing to the battery! It has gradually got worse over the past few days. I see this is a common problem with this battery from just reading a few reviews. I went to the local apple store expecting to have to fork out $130 for a new battery (especially since my warranty had run out long ago), but they replaced the battery there and then free of charge!

The 'genius' told me that they replace batteries FOC with this (bulging) defect even if the warranty has expired.

Very pleased that I got a new battery for free, but was shocked at how my old battery started to come apart. Surely this could have damaged my laptop if left too long!

Just replaced the second battery due to overly hot MacBook Pro. I bought this computer in June, 2006. Once the computer overheated and wouldn't shut down. In a panic, I put it in the bathtub (no water, of course) and then gathered my senses and removed the melting battery. I've had bizarre things happening to my computer this time, but didn't associate with the battery, because it wasn't bulging at first. Well, it did warp and the battery was the cause of "weird" (even the Apple Tech was stunned by what I described) happenings. Random applications would open when I moved the cursor over icons, files would not open, but when the cursor moved over folders, they would select and move to the location of their choice. Words deleted without me ever touching the delete button. Lots more....

Is there any chance that Apple would replace/repair this computer? I think it's a
hazard.

My battery lasted for 3 years. A couple days ago it started to bow out and now it has bowed out so much I can see inside it. This doesn't seem safe at all. What's up, Apple?

I did not buy my 17 inch MacBook Pro new, but the bulging battery finally explained why it could not hold a charge for more than a couple of hours at most. For the past 2 years I have left it plugged in almost continually.

My 2008 Macbook Pro had the bulging battery problem. Unfortunately I threw out the battery rather than take it back to Apple. I regret this as I understand that Apple will sometimes simply swap the battery. Anyway my advice is to speak to Apple first.

Also if you don't replace the battery and run your Macbook off ac only you will find that OSX throttles the processor which reduces performance. I could not understand why my Macbook was having problems with some HD flash video now I realise it was because I was running on ac power only. (apparently the reason for this is that if the system is under maximum load it can temporarily require more power than ac can give).

Laptop has been in a desk drawer for about a year (no dropping or exposure to weird magnets or temperatures). When I took it out, the batter was bulging. People at the apple store said it looked as if it was "fried". Really don't know how it happened, but I guess I need to buy a new battery. I'm just worried now that it might happen again. Any advice as to how to avoid?

I've had my Macbook Pro for just over 1 year and about a month ago the computer started shutting down without notice. Last week I was working and as I was typing the computer started rocking back and forth on my desk. The battery had warped before my eyes.

I've had no complaints about the computer and I can't be that upset at apple for not replacing my battery..I don't have Apple Care, but I would expect that a failure this drastic would mean they'd at least split the cost with me, considering I bought their most expensive computer!

I replaced my battery in the beginning of this year. I have yet to throw away the old battery for reference reasons b4 I purchased a new one. Although it is no longer in use it is still growing outside of itself. I thought since I am no longer using it and it is sitting in a cool area that it would be ok. It is still growing. I almost ruined my compartment for my battery by forcing it until I haaad to get a new one. It pretty much let itself out of my laptop. A safer alert would be ideal for consumers to know they need a new battery.

I am actually surprised out how consistently terrible the MacBook battery performs. Mine has done exactly the same thing. The worst part, in my opinion, is the 45 minutes or less charge capacity. I am jealous of my friends/ fellow students that have other computers that they can just get to class and start typing without having to find an outlet to plug in. I have already admitted that rather than a "laptop" or "notebook", I have a really expensive desktop with a built in screen.

Since I don't ever take my laptop anywhere with me, just leaving it on its fan on my desk at home, I just took the battery out and leave it in my drawer. While its plugged in, it does not require the battery to operate. I am pretty sure that the only reason my 2006 model is still only on its third battery is because I wised up, took the battery out and don't even use it.

By the way, the only reason I gave it 3 stars instead of one is because I think this is a useful tip, and I wanted my comment to stand apart from all the other 1 Stars.

My rating is 1 star
