I would try with the old charger.
Yes my understanding is they are both 36v. There is nothing written on either that i know of. Anyway have charger plugged in now and it reads with a red led light. The charger that came with the new battery read with a green light . The other clue i have that something is wrong is that the last two times that i went out for a cycle the battery was getting lower and not higher in charge according to the meter on the handlebar as i used the throttle. So i wonder if the new charger really works at all. Anyway will get it a few hours and see if the light goes to green and see how much power i get on my next cycle experience tomorrow. Glad i was thinking overtime about this last night :0)
