Just a note with those holders. They shouldn't be used in anything that will be shipped as the battery can get knocked out. The original shipped batteries were soldered in so they could be shipped safely. In fact a lot of the time the cells were taped or cable tied as well as soldered in on some bits of hardware!

The newer CR2032's have much lower mass and can withstand many more G's before it's an issue so they are usually in holders.

That is why I added the second Mouser link for the retaining clip, which is frequently missing from old stock. It takes a screwdriver to unclip it, plenty secure for transportation.

Got it thanks. That link crashed Mouser the first time so I assumed it was a dead one :)
