stingerman,
The unfortunate word is that they won't. The reason is that when the orgininal SC1 came out, it worked well with exising 123 batteries e.g., there were no design or manufacuturing defects and the product functioned just like it should.
With the advent of Ultra and SF batteries, the problems began because the batteries were slightly larger in diameter. Accordingly, SF redesigned their product.
I wish they would replace them as I have several that are going to go in the recycling bin shortly.
