Quoted from Niterider:I’ve been using Franks battery boards in most of my machines and I’ve not had any issues so far. Just remove your old battery holder and solder one of these in place and all you have to do is occasionally pop in a new button battery. They are pretty straightforward.

If you're soldering anyway might as well just buy a coin battery holder and solder it on the board itself
