When you want to use the steam battery to open sully's door, you have to hit use outside of his door. There is a blue faded line on the number 5 on the steam pressure meter and that is the number you have to get to. So whatever number it goes to on the meter when you click the wheel to turn it, you have to add or subtract numbers to get to five. Hope this helps! :p
on the trash can
You use the steam battery in Gear Alley. On number 5.
click use by the sullys place. I havent figured out the combination let. Someone let me know of they have.

In the museum.
use it with the steam engine and steam battery to get into living quarters.
