The battery life was dwindling on the original battery in my G4 1.67 GHz 15" Aluminum. I replaced it with an after market battery touting a 25% capacity (5000 MAHz) increase. It does seem to have an increased capacity but the battery indicator has become erratic. Today, with a gradual decrease from full charge to 62%, suddenly the notice came on warning that it was running on reserve power and it showed 4% charge. I have twice let it run down to shutdown and then recharged it. The indicator still is erratic??
