Narrative:
While changing circuit breakers for external power, disconnected aircraft's batteries. After completion, forgot to reconnect batteries because mechanic working with me turned power on. Thought he connected batteries, went to gate, batteries were showing zero volts, charger not working. Mechanic on line reconnected batteries, aircraft was dispatched.
