Battery power with displays

I have built with Arduino a clock/calender which has a 16x20 LCD display, a 4 Digit LCD display for time display and a clock/timer chip which maintains its settings with a coin battery. I have tried powering the setup with 6 Eneloop AA batteries in series but it ran out of power in one day. I am loo...
