It sticks up a good inch or inch and 1/4 above the frame. The wires dont reach the terminals either. It had a CB9 B in it when I got it, that didnt last but a couple of weeks ( im guessing overcharging was the culprit) but it fit great. The manual only specifies 12V 12 amp. Google hasnt been much help either. I got this bike for my GF to learn on, and now I look like a moron. I really need some help on this one, Im not an official mechanic but I have/ have had a bunch of bikes and am not a newb nor a moron, but am beginning to wonder about that last statement.....Its such a cute little bike and only 1100 original miles, I need her to be riding it in the next week or two. TIA
