Reviews for Rechargeable Battery - 15-inch MacBook Pro (aluminum)

This was billed as an eight hour plus battery but I have to concur with the other reviewers that I have never experienced better that two hours, 50 minutes. I have done the monthly or more frequent discharge and full recharge but to no avail.

I purchased the 15" MBP new in late 2008 when they first came out. In the last few weeks I have been noticing trackpad problems and I thought my trackpad was going out. After removing the battery and inspecting the compartment I realized that my battery had swollen and was causing the trackpad problems. Removed the battery and the trackpad is working as good as new. Now however it looks like I am out the $130 for a new battery. Battery has lasted about three and a half years. Probably not bad for a lithium-ion rechargeable but the replacement cost is kinda steep.

It's been a great laptop. Took it to Iraq with me in 2009. Only problem I had was a worn out fan earlier this year in May 2012.

I use my macbookpro daily. Plug in numerous times a day plus have extended times without plug in. This battery has lasted 38 months. It's now dead. Only had reduced time on the battery in the last 6 months. Pretty darn good for a rechargeable and FAR better than anything I ever had with all my HP laptops over 15 year period. Glad I switched.

It's a battery, even if it IS an Apple battery. I got exactly two years out of the battery that came with my 15 inch MacBook Pro. I was dumb back then: I just forked out $99 and slapped in a new one. I got two and a half years out of that one and was only a little smarter: before forking out $129, I checked the system stats and discovered the fool thing only had 62 cycles on it! You can bet I have done some research and will be doing some cycling this time around! Maybe I can at least make it to three years on lucky number three battery? Even at this rate it was only about $3.30 a month for the second one.

Had to replace the first battery because the old one swelled up so much I couldn't use the touch pad any more. The second one hasn't even lasted 6 months and now reports a "Service Battery" alarm. I'm happy with my MacBook Pro but I really wish there was another option for the battery.

I'm going to order a third battery for my MBP 5.1 That is one per year, the first one lasted 14 months the other 2 not quite as long, come on Apple get you battery problems fixed, it ridiculous having to buy a battery every year for a computer that is only used on battery power a couple of hours a week, the rest of the time it's always plugged in to AC power.

I bought a new 15" MBP in 2009 with an extended warranty. The first battery lasted less than two years, and swelled sufficiently to prevent the trackpad from operating properly or allowing the battery cover to fit flush. I got a replacement battery free and, when the trackpad failed to operate properly, that was replaced also. A year later, the second battery failed - bloated as a dead pig - and, the trackpad didn't work, and the battery cover wouldn't fit. When I tried to purchase a second battery from the "premium reseller" (my warranty had expired 2 months earlier, the "new" battery serial number indicated that it was almost 3 years old. My laptop is now a desktop.

I have been reading all these bad reviews for the MBP battery pack and honestly I couldn't disagree more. Beside the fact that it is a bit costly (130dollars? com'on! I would say 90dollars would be reasonable), the battery did well all these years. I am sure people have different experience, although on my previous PowerBook I had also a good battery experience; I changed the battery once on the fourth year, half a year before I got my MBP.
I bought my MBP on Oct 2008, just a few days after the redesign model launched. So since the beginning of Nov 2008 I have been using my computer every single day, mainly as a desktop replacement. Just for you to get an idea, the iStatNano widget (I really don't know how accurate it is) shows 1232 cycles and 74% health. I have to say that the health was around 90-95% all these years and has been falling the last month noticeably.
I have been unplugging my Mac everytime it reached 100% (or 99%, sometimes it never got to 100) and plugging it in after the "battery running low" notification (it is extremely easy to do so with the magsafe). Other than that I didn't take any extra care.

Will I buy a new battery? Well, my MBP is kind of old, a friend of mine has the 2010 model and it really goes superfast (i5/7 chip vs the core 2 duo.. huge difference).

I will probably get a third party battery till the (much anticipated) new MBPs are launched end of 2012 or early 2013. Apple is definitely losing some clients with that kind of pricing.

PS I am really curious of how much it costs to all these people who own the "non-user replaceable" MBPs to get a new battery pack..

Ive had this MacBook Pro for about a year and the battery went from lasting 7 hours to lasting 2 hours.

This is worse than my 4 year old MacBook.

If Apple makes the batteries, they should have actual battery companies make the batteries instead.

I like Apple, and they make GREAT products, don't get me wrong, but batteries, not so much...

In spite of the reputation, Apple's batteries (largely due to the software that controls the battery, not the battery itself) last far longer than batteries in typical PC laptops. After several years, my battery will still give me 2-3 hours of life in my Mac.

But I have the same issue that DB has. My battery swells and it interferes with the operation of the track pad. When I first turn the machine on, everything is okay, but as the battery heats up, it swells and then the trackpad doesn't work properly.

Personally, and even though the machine and battery is out of warranty, I consider this to be a defect and IMO, Apple should give some credit towards a new battery.

I've had my macbook pro since this model(redesigned) came out in fall of 2008 and have had great success with the machine both in performance and wear. 3 years later I'm still on my first battery and only now starting to see a slight taper in it's life on a full charge. I see comments people have made on this exact batter but they are referencing older vintage machines. People the 2006 or 2004 machines had a whole different technology. These are a rock solid design and this batter is for the 2008 unibody and newer MBPs. I couldn't say more good things about this machine and battery combo. It's a gem.
