Guy's, Anyone know where I can get this coin battery (The one of the left) from.. You see the only ones that I see is the one on the right (That battery has the wrong solder leg spacing. The legs are too far apart (The Negative leg)..

I thought you were going to solder in some contraption in order to use a conventional cell ???
Been there, done that and old enough to know better.....

The difference doesn't look difficult to handle.

Try bending that little legs till reach each hole.

It's for my JR XP8103, as it still has the old battery in it. If I solder in a battery socket (on this TX).. The back cover won't fit back in place..

Thanks, Though bending the negative leg in makes the battery too high on one side, so don't look nice (I've tried that in the past)...

Oh you can't bend the leg in because it's spot weld to the edge. You see the other coin battery the negative leg is spot welded the further in..

I could have told you that but I wanted you to find out for yourself !!! That’s the best way to learn ....

I did do a backup battery change on my Futaba Zap radio but you had to strip down half the radio before you got at the battery which is sandwiched behind the screen and the main battery, so what I did was drill the battery box exactly where the backup battery is located and soldered a battery holder so it would be easier in the future to change the battery, see pic ignore date on battery.
