Looking at the docs for that board, it is not properly documented. If
you look for the given Digikey part number (P202-NC -> P202-ND) It
appears that it actually uses a BR2325/HCN, and not a BR2325. Both are
Panasonic lithium coin cells, but the former has solder leads. Any 3V
lithium coin cell with similar lead spacing (or a socket/cell combo),
20.5 mm, should work fine.
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.
If the battery is 3v I am wondering if the capacity is important for this purpose? Maplin have other coin cells 3v I will look at in the shop.
Thanks for the helping hands,
