Very small batteries and connecting it

Not sure if right forum.I have to connect a cr2025 battery to a circuit.Is there any glue that would make the connection. The old battery died and really do not want to use soldering iron on a battery that small.

If you could scrounge up one of the sockets they snap into you could solder to that.
I also got a lot of hits using "conductive glue" or "conductive tape"

You could make a a flat disc of solder on the end of each wire, cool, pinch it on the battery, and just hit it with a wrap or two of electrical tape.

You didn't give us much info as to the use but in addition to battery holders you can get tabbed cells.
Just search for CR2025 with tabs.

Get the tabbed cells. I tried soldering to a CR2025 and the heat boiled some of the electrolyte out. I couldn't get it hot enough to melt solder without destroying the battery. That's why they are spot-welded
