"Thank you. But as true as that might be," because she's positive at least that Clu finding a lost program would end very badly for the program, "I'd rather you keep your hand if possible. You could just refill my spare batteries off your arm when you have time."

big rechargeable batteries and not Rinzler's ship. They don't need any more damage to the Moira.
