X6x CMOS battery wiring

#1 Post by dandreye » Sat Dec 08, 2018 9:01 am

Hi All,

Could anyone please explain what the "extra" (3rd) wire in X6x CMOS battery is for? Assuming it's a CR2032 (3V) cell inside I'm tempted to make my own because of their ridiculous pricing (>4 times more than what T4x batteries sell for).

Thanks in advance!

Can't remember if it's wired to the positive or negative of the CMOS battery.

Cut open the yellow plastic around the cell, so you can see where the wires go.
Be careful not to short it.
A piece of tape will fix it again.

My guess: RED to PLUS
Both BLACK and WHITE to GROUND
