Hello, New to the forum. I have a Milwaukee M18 Impact Driver and I was given it by a friend and only charger he had was a Milwaukee Jobsite Radio and of course he wants the radio back naturally, so i took the connector off the radio, so im left with the connector that the battery clicks onto which has five wires on it and so long story short and to the point, I was wondering if it was possible first of all, and how would i go about connecting it to another 18v charger i have (not milwaukee). Do it have to be milwaukee, or can i use another brand, what are my options and is there a diagram available?, in the long run of things im trying to be cheap and plus i just like to build electronics. Anyway please help and Thanks for your time.
