Futaba had to make a decision to do it one way or another. There are pros and cons to either method, obviously. Dave, your original comlaint was that Futaba tried to save from using even a 20cent part. I was simply pointing out that the tabbed battery cell is no cheaper, and probably cost more to implement overall, than using a cell holder. I was also pointing out the reliability benefits of the way Futaba did it vs. coin cell holder with spring clip, which is subject to corrosion and other enviromental related contact problems. We use industrial singlle-board computers for our rig instrumentation embedded PC systems and have had problems with those pesky coin cell holders.
