I am using PIC18, an RTC DS1307 and an LCD. the timer is running in good condition only when it is powered, it does not works in battery mode. Can anybody solve this problem......?

What I mean is that the RTC must continue displaying the time when it is disconnected from 5V and connected to the LCD again with 5 V again. Otherwise how can I test that the clock is running even in battery mode. Is there any other way?
