Rating: 5/5 Excellent product March 28, 2015 The battery in an old Powerbook G4 wouldn't last more than about 15 minutes. We ordered this NewerTech battery to get more like out of this old computer. Worked great! After conditioning the battery (the instructions were great) the computer now lasts several hours on battery power. Looks like it will give several more years of service.

I would recommend this item to a friend!
