I was talking to my Interstate Battery guy the other day about used batteries. He said they get alot of them at various times. Usually at the end or beginning of the golf season. They test the used units to see if they are still usable. Many are. They just had low states of charge from sitting around. Most of the batteries they see are the Interstate brand but sometimes get other brands as well. I got 4 Crown CR245 (245 ahr) for a floor cleaning machine we have at work. He said they usually get $30 for the used units and they need a core battery as well. Post to this thread if you are needing any used batteries and I will see if they can fill your needs...Rich
