Well, I got the above battery, soldered it in place, and left the cart in the EZWriter II all night long (green light on). No joy. Not charging. I don't need EZ Manger running, do I?
I have an EZ-Flash III 1Gb, and the battery died some time ago. I tried to replace it with a standard button battery but failed. In the process I lost the original battery. Can anyone tell me what the correct battery is for this flash cart?
