I tried that with a company laptop, I couldn't wait to leave for the day, so instead of shutting down or hibernating, I put the laptop into sleep mode :P
The battery didn't surprisingly last overnight! BUT when the batteries do go flat, all that happens is the laptop awakens and shuts itself down.
So I would agree, put a switch onto the main positive cable and switch it off at night, so its running only on batteries.
