Rechargeable Battery - 13-inch MacBook (White)

this is a great product if you use it properly. Because it is a lithium polymer battery it needs to be charged fully then drain fully and charged fully etc... to keep it healthy. I get about 4 - 4.5 hours out of this if I i drain it and then charge it (like above). when i first used it like normal i only got about two hours until i realized that you had to do this. This is a great product and if you use it in this way you can even achieve as much as five hours! This is a great product and i would highly recommend it.

From the first day I got the battery, I charged it fully, let it get down to 15 or 20 percent and then charged it again. My computer is 55 months old, and the battery has had 1000 charge cycles and I still get 2.5 hours out of a charge. The battery health is at 82 percent. There's really nothing else to say. …More
