What's wrong with mysony PCGA-BP2T battery?

Question:I'm planning to leave my sony PCGA-BP2T 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 it.My battery in this one goes about 3 hours.so i suggestion you buy a new one and you can choose : ASUS M68 battery , ASUS M6800 battery , ASUS M6N battery , ASUS M9 battery , ASUS M9A battery , ASUS M9F battery , ASUS M9J battery , ASUS M9V battery , ASUS S5 battery.
