Reviews for Rechargeable Battery - 15-inch MacBook Pro

After almost 5 years, I finally need a new battery. INCREDIBLE! This is why I will only own a MAC. Thanks for putting out a great product!

I have a Macbook Pro 4,1 and at 37 months old, my battery still has 86% capacity after 120 load cycles. I generally use it plugged in, but it lasts a few hours still if I keep the screen illumination down

I've used two batteries since I got this computer new because I've done lots of traveling and I always have to keep a charged-up spare handy just in case. One of the two is starting to get a little weak now that it has around 70 cycles on it. Doesn't seem like that much of a surprise to me. It still works, but it just doesn't hold the kind of charge that it did when it was new, so it's time for a new one. For the most part, I've found that the battery would last longer than I could keep awake on an airplane - so if the airline breaks down and coughs up a source of electrical power it just gives you a means of falling asleep to iTunes as you cross the Pacific, which beats having to rely on the airline's tunes every time!

My computer is two years old. I bought it refurbished. The battery has 520 !!!!! cycle counts and keeps my computer powered up for two hours or so. Of course it's not 5-6 hours as the new macbook pros but pretty good. It says: 'Replace soon' but it's been saying that since the cycle count reached 450.

I have the original battery in my 2007 MBP with over 500 cycles. It still holds a charge of over two hours fully charged and lasts much longer if I'm only word processing. It appears I got one of the few good batteries.

I ONLY USE IT WHEN I TRAVEL BECAUSE I HARDLY CHARGE THE LAPTOP, I CHARGE THE BATTERY AND PASS IT TO IT. SO I RARELY CHARGE MY LAPTOP THE NORMAL WAY BECAUSE LAST TIME, THEY SHUT THE ELECTRICITY AND I HAD TO REBOOT THE WHOLE THING, WITH THIS BATTERY I CAN HAVE IT AS A BACK UP AND NOT WORRY SO MUCH. THIS HAPPENS OFTEN IN EUROPE SO ALWAYS GOOD TO USE IT FOR THAT REASON.

I bought my macbook pro in the summer of 2007, and now - almost 3 years later - it has started failing me. While I'm not excited about dropping $130 in order to purchase a new one, I do believe that I've gotten my money's worth out of this battery. I think mine lasted quite awhile considering that Apple recommends that this battery be replaced at about 300 cycles. Battery life wasn't the best, but I didn't mind that too much. Not really much to complain about other than that.

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.

It seems most of these reviews are useless. It really depends on charge cycles. The analogy I'd use is it's like tires. If you put 80,000 miles on your car in one year do you complain your tires didn't last more than a year? No you just buy new tires. Same thing with batteries. If you go through 300-400 charge cycles in a year of course your battery isn't going to last long.

I am happy with my purchase - I had to order a battery after my original laptop battery hit 300 cycles (1 1/2 years) and it's life did not last long. I ordered a new one because I am a student and I need my MBP to be portable.

I would say that this battery is as good as the other battery, IF you properly take care of it. It's not just about the cycling. DON'T leave your power cord plugged in when your laptop is off and it's fully charged! Only when you're actually working on it. That will just ruin your battery.

After 1 1/2 years of cycling almost every day or a few times a week, and never leaving the power cord in when it's not needed, my battery was still at about 4 hours, even with the Internet, but diminished after it's 300th cycle.

Testing out this product, I am happy with it, but wish that we could get an 8-hour battery for our older MBP's. Mine replacement is lasting me 4-5 hours using the Internet and adjusting settings for better battery usage.
