A Battery Bot was a small robot that acted like a battery, supplying power to machinery when plugged into a socket. Battery Bots had legs and used them to escape from having to supply power to machinery, and flee from anyone who tried to put them back in their sockets. They were, according to Vullards, unreliable as they were very rebellious and often went on strike. They could also speak, and used their voice to complain and insult anyone who tried to put them back in their socket.
