I have had a G90 Relay system for about 3 years now. I recently tried to change the batteries and noticed they were not connecting properly and actually rattling around in the transmitter! The old dead batteries were not and still fit and connected well. Both Energizer brand. The old batteries are actually a millimeter or 2 longer than the new ones I had bought. Same with new Duracell's I bought. Is anyone else having this issue and is there a fix? Seems like they are making AA batteries shorter now which for spring loaded devices it's no big deal but for this transmitter its the difference between it working and not working.
