Very very few. The technology for battery pack saving was just really starting out in the days of the NES. It was possible on some of the bigger games such as Final Fantasy, Metroid and Zelda though.
The NES Nintendo used a battery usually for saves. Unlike todays systems there was no hard drive or memory card so if the game didn't have built in capabilities you couldn't save. A lot of the games used codes that you entered that allowed you access back to the point you were at. Hope this helps mate.
