On the Bridge or Pharos phases when you are clicking on the zaps, there are 2 buttons to the right of the progress bar. One looks like a hammer and one looks like a lightning bolt. Clicking the hammer or anywhere along the progress bar will use one energy zap and increase the progress bar by one unit. Clicking on the lightning bolt, if you have a battery will offer you the option to use it and increase the zaps counter by 500. If you don't have a battery, it will offer you the option to buy one for 90 piastres.

I'm not sure where you heard the "mission menu" from, but that is how you use the batteries.

Good luck!
