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

I've tried the "best" generic batteries, and they all stink. They generate tremendous amounts of heat (which is wasted energy and shows a lack of efficient operation). This battery works well, doesn't overheat and gives solid battery life.

This is the only real battery worthy of your mac. Don't be fooled by imitators.

I bought my Mac Pro 3 years ago. Only now is the battery not holding its usual charge. By that I mean, the charge lasts only 3-4 hours instead of 7.
Considering that my husband bought a PC at the same time, and that his battery is now, at the same time as mine, giving him a short recharge time, I don't think that my Apple battery has disappointed me.
So, I give it a FIVE STARS rating.

I have had this same battery on my 15in MBP since mid 2009. I have had no problems with it, but lets face it having a battery for over 3 years is pretty good. One thing people need to realize is that you are not supposed to drain you battery ever. New batteries do not have the "memory" that old batteries have had. The trick to long battery life is keep it above 20ish percent and do not leave it plugged into a power source, unless you absolutely need to. If you treat it right this is a good product, I will be buying a new one!

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.

Most of the issues I have heard and read about battery life are connected to how the battery is used (or not used). If you leave any rechargeable battery at full charge and plugged in you are going to experience issues with battery life and swelling. Regardless of brand of the battery. Try actually using your laptop for what it is. If you use your computer pretty much as a desktop, buy an iMac that will solve your issues with battery replacement. Otherwise remove the tether from your MBP and use it anywhere and everywhere. You should get much longer life out of your battery.

Just wanted to chime in because I saw many negative reviews. I've had my late 2008 MacBook Pro 5,1 for more than two and a half years now and after 542 cycles I'm still at 93% capacity. That is all!

The battery is a finite product. Apple clearly states that the battery will hold less of a charge after the 300-400 charge/discharge cycles. If you use your computer everyday, thats like maybe a year to a year and a half. Don't go discounting all of Apple just because this clearly expected degradation happens. Everyone's usage style is different, therefore performance will differ from person to person. The expected battery life is stated under half screen brightness, and web-browsing. I give this product a 5 star rating because it performs as it is advertised.

I have had my 15" MBP for 10 months now and not a lick of problem, I just followed the guide lines for any rechargeable battery...Charge to full then run it dead, then charge it full and repeat.... I have 53 cycles and still get 7 hours out of my battery the original design capacity is 6900mAh now it is 6849mAh not bad after 10 months

Nevermind all the people here trashing this battery, they seem to not know anything about how to maintain it and take proper care of it. Discharge the battery twice a month and it'll keep on going for several years. I'm using a late 2008 MBP (the first Unibody ones), almost two years and at 145 cycles, it holds 94% of the original capacity (4333 mAh out of 4600). I'll definitely buy a second one when this one reaches 65%, but it seems it wont for a loooong time.
