What’s wrong with my Apple A1078 battery?

Question:I’m planning to leave my Apple A1078 battery while it downloads for 3 hours… its fully charged and the setting for the brightness of my monitor is in its lowest possible… and the monitor automaticaly turns off in 1 minute if you go idle… Do you think it won’t drain that quickly? what should i deal with it . Answer:It depends on the strength of your battery. You can check it by hover over it with your mouse. It should say how much time you have left on battery .My battery in this one goes about 3 hours.so i suggestion you buy a new one and you can choose :Acer BTP-43D1 battery , Acer BTP-550P battery , Acer BTP-63D1 battery , Acer BTP-39D1 battery , Acer BTP-34A1 battery , Acer BTP-25DI battery , Acer SQ-1100 battery.Good luck!
