rene_canlas' guide worked on 3 out of 4 batteries for me! Thanks so much rene!

I had a red light and a green light. Took the batteries off and tested voltage on both. One was 77v and one was 5v. So then I plugged in the Segway and tested the ports that the battery plug into. One read 27v. And the other read 11v. Not sure if that's a problem but it seems odd. Either way I used as heavy gauge wire as I could did negative to negative and positive to positive and let it sit for 40 seconds. Feeling both batteries the entire time and with a fire extinguisher nearby just in case. Neither battery heated up and when I tested batteries again the one that was at 5v was now reading 60v. So I plug in the two batteries on my Segway and Wala. Two green lights Segway recognizes both batteries now.
