I am not really understanding the full purpose of the battery but Maplin here in Ireland does not know of this BR2325. So I am now thinking that I can if possible use another 3v coin cell for this purpose. I did look on the Digi Key web site and the number P202-NC does not come up.
Look for P202-ND. I'm not sure what the "dash" suffix signifies, but it seems that Digikey ends _all_ their part numbers with the same one. I suspect they changed from -NC to -ND at some point (but I don't recall it ever not being -ND, so maybe it's a typo).
If the battery is 3v I am wondering if the capacity is important for this purpose?
Only for how long it can provide backup power.
Maplin have other coin cells 3v I will look at in the shop.
Myself, I'd look for a CR2025 holder which would fit in that location, the cells are easily found, and with a holder, replaceable. If you think it may be powered off a lot, perhaps a gold cap, or rechargeable lithium.
