Hey guys, i need some help. I have a logitech g930 that keeps dying on me. The battery doesnt hold its charge that well. So i pulled out the battery and im replacing it with and old cell phone battery i have lying around.
The original battery is a 600mah 3.7v 2.3wh and uses a 3 prong molex connection. (Red, yellow, black)
The cell phone battery is a 3.7v 3500mah by Hyperion. The battery has 3 contacts but im sure the middle is for monitoring which leaves the pos and neg.. My question is, on the super mini molex connection is the red positive and black negative? What is the yellow for?
