@gunrunnerjohn posted:The 3V BCR is simply a 1.5F 5V supercap and a couple of wires. When I take the old battery out, I just clip the wires at the battery, solder them to the supercap with a little heatshrink for insulation, and I have a replacement battery with the correct connector. Remember, red to positive on the supercap.
Here is a link to a supercap on DigiKey that should do the job: https://www.digikey.com/en/pro...22C155PSBA0H/6166275
