I'm new at this so bear with me.
I was trying to desolder an SNES battery from a cart that was pretty much non-working.
I managed to suck away the majority of the solder, but from what I can tell, the remainder of the solder on the back side of the cart is still intact and won't melt. I was wondering if anyone knows anything about desoldering the batteries because the battery I'm trying to remove won't come off, and the remainder of the solder left won't seem to reach a melting point.
Does anyone have any advice? Or can point me to a thread or tutorial that works (the one I used didn't work well as you can imagine).
