: Almost all of the available coin cell battery holders for this type of battery have a
20mm lead spacing, the original batteries in these Yamaha units have a ~14mm spacing,
making the 20mm holders incompatible without making modifications. Since this holder has
wire
leads it makes it more universal and compatible with a variety of lead spacing pcb mount footprints.
