Why is my battery pack melting? Answered
I am new in electronics, and I am building an LED circuit with 2 AA batteries, green LED, and toggle switch. I put the batteries in the circuit (it's a 9v battery clip with a Two AA Battery holder) and it ran for a bit, then the bottom started to melt a bit. It is an older AA holder but the 9v clip is new. Is it because of the old component, switch, voltage, anything!
