I'll make the assumption that you know the basics here...

To make well-filtered voltage source from your battery, first run it through a diode (forward biased).  Then put 1000 uF per amp electrolytic across it.  Then follow the recommendations of your voltage regulator chip manufacturer for additional chip input and output filter capacitors.
