If you are looking for Apple Laptop Batteries, you might want to check them out. I personally don't own an Apple but my sister does. Needless to say she loves it! Never had to replace anything on it but she always has an extra battery in case she needs it. I own a less name brand laptop but they do carry my battery. They also carry batteries for camera, camcorders, phones, etc. Check it out! The ultimate place for all your battery needs.
I have not purchased from this company. All thoughts are 100% mine.
