Just bought a new battery yesterday from "Experimac" in my neighborhood who seem to specialize in Apple products. Under my charge info it says cycle count 0, condition normal, amperage -22, charge remaining 6502 out of full charge capacity of 7000. Just bought it yesterday. I got it at 63% charge, used it for about 2 1/2 hours on battery and it slipped down to about 56%. closed the lid, left it for about 2 hours in hibernation mode, came back and it was at 7%. That doesn't seem right or is it? I've set the settings as much as I can to conserve power. If they were open today I would have taken it back but next year I will.
