You would figure that those batteries would be fairly drained and have significantly higher internal resistance after all the other tests, so there is a good chance it would have worked, but it's not guaranteed. | |

I did an experiment with a red and blue LED, both with 100 ohm resistors in series as the OP suggested. On 3V, 50 ohms in the positive lead was enough make the blue LED go out when the button was pressed. | |
