    Rather, "power" is uncountable when it means "energy". Consider: "her superhero powers included unaided flight and mind-reading" :)

  • I actually thought about that. Decided that batteries should not have superpowers. Most inanimate objects just don't have the required responsibilities. Sep 24, 2014 at 13:27
  • The battery is dead. Before it died, was it animate? The powers that be are undecided.
