Apparently the reason why I ruined my camera battery in a short period of time was because I over charged it every time I plugged it on. I used to leave it charging for almost a day or because of my forgetfulness. This is why I resonate with designs like the Dialug that integrate a timer into the socket. So for gadgets that need 2-3 hours of charging, the timer automatically turns off the power supply once the time is up.
